This is what is most difficult to do in the theory of relativity.
Explaining to the housewife that she has to bring back carrots, potatoes,
and two red peppers from the market is very easy.
And she will understand it easily. Explaining the theory of relativity is
more difficult, even if the equations are trivial.
The point is, it's jam-packed with counterintuitive phenomena and little
pitfalls.
One of the most famous pitfalls in the history of this theory has been the
confusion that all scientists have made between the notion of chronotropy
and the notion of measuring time by a given watch.
It's not the same thing.
If one thinks that it is the same thing, a paradox, that is to say a pure
absurdity, will immediately appear. We call this paradox that no one has
ever been able to solve (except by shouting from the rooftops that it has
been solved without having solved anything at all) the real paradox of
Langevin.
Indeed, to say that time passes less quickly for the two twins is absurd.
This is FACTLY absurd. The error stems from the confusion between
measurements taken by watches and the chronotropy of watches.
I want the chronotropy to be reciprocally lower on the other watch: To'=
To/sqrt(1-v²/c²) and that this phenomenon is constant and invariable
with the direction of movement of the observers.
But it is not the same with the time that these watches are going to note.
We must not forget that chronotropy is not the only measure to take into
account, but that the universal anisotropy must also be taken into
account: crossing space is not ONLY moving away in space is also crossing
time, it is also really moving away in the past of the other. Let t'=
t.(1+cosµ.v/c)
The real equation therefore becomes:
t'= t (1+cosµ.v/c)/sqrt(1-v²/c²)
There is no longer any paradox.
Although the watches have a chronotropy which makes the other watch really
beat and reciprocally less quickly, in the end, the effect on the times
themselves is not reciprocal, which would be, it is true, totally absurd.
, and the road open to all the critics of the world's cranks. And we could
only agree with them.

Chronotropy: "The rate of muscular contraction, especially of the heart."

So you believe watches are mechanically distorted because of velocity?
What YOU want is irrelevant. What counts is what the universe wants.

To'= To/sqrt(1-v²/c²) and that this phenomenon is constant and invariable
with the direction of movement of the observers.
x' = (x - vt)/sqrt(1-v²/c²), t' = (t - vx/c²)/sqrt(1-v²/c²)

The twin's movement according to the stay-at-home twin is x = vt, so
t' = (1 - v²/c²)t/sqrt(1-v²/c²) = sqrt(1-v²/c²)t, not the inverse that you assert.

It's useless to ascribe a mechanical explanation to the so-called "paradox.".

This sentence does not mean anything. It absolutely does not explain the
phenomenon. When I read this, I find it sad to cry, not that a scientist
could have written such bullshit, but that other men reprized this silly
sentence as if a genius had spoken.
It is as if he was saying: "a dog is a dog because a dog is a dog".
I have said over and over again (but nobody seems to care) that it was not
the accelerations that explained the phenomenon, and that almost all of
the differences were made during the purely Galilean phases. We also said
bullshit of the type "the twin jumps of reference" or "the needles panic
during the U-turn". This is all sad.
We drown the fish with words. Nothing really obvious or understandable is
explained. In short, as I have always said: "The theory of relativity is
right, beautiful, and experimentally obvious. But when a man is asked to
explain it, he does not know how to do it. Everything turns to dust. under
the rug because we don't know how to say things ".
The accelerations? LOL.
And why not the papal balls?

question 1.
What must above all be understood is that a physicist is first and
foremost a man.
And that when a new idea appears, it is necessarily criticized in fact.
Whether it is correct or not does not matter. We criticize.
As for the Langevin paradox, as I said, the problem is human narcissism.
We made Einstein a religion. nothing is worse than wanting to give a drink
to a religious, and scientific theorists are religious who do not know
themselves.
I explain (and there, it's beautiful to cry about why there is a paradox,
and HOW we solve the paradox).
It is unheard of in the history of mankind. No one had ever done it.
But they answer me: "Uh ... no, there is no paradox, for the good reason
And I keep getting the same ridiculous excuse "there are accelerations",
"there are benchmarks", the situation is not symmetrical "," there is a
time-gap "...
I explained that all of these excuses are either "a dog is a dog, but you
can't explain why a dog is a dog" or are downright bogus. Like this dark
story of the Blessed Virgin which makes a time-gap when it revolves around
Tau Ceti. All that is pipe. From religion all learned. There is no
time-gap. When the twin spins he sees the earth which marks t = 3 years
and when he reappears on the other side he still sees the same earth which
still marks 3 years.
On the other hand, and there, we do not talk about it, there is a real
relativistic spatial zoom effect (elasticity of distances and loggers) and
the earth that he saw at 4 light years (longitudinal relativistic
contraction well understood) passes to 36 light years.
The distance the earth must now travel towards him, at an apparent speed
of 4c, and this for the remaining nine years of his journey.
It is a precision and an accomplished beauty.
But that's not what we teach on the college bench.
I know it.
But it's not me who makes the programs.
In fact, I don't exist.

What must be understood (I beg you to be open-minded) is that the
acceleration phases do not matter, or so little that they can be
neglected.
That is just a claim on your part. Can you support your claims?
For instance, if the Galilean phase lasts only a few micro-seconds and the deceleration/acceleration last a few years, then which phase induces the most time dilation?

You see, it can't be neglected in this case. In some cases it can and some cases it can't. The computation will tell us if we should neglect it or not.
It is not the accelerations that induce the effects, but the Galilean phases. The accelerations are negligible
and neglected in the problems.
Those problems with accelerations, if they say it's neglected, they should ship port their claim, explain why it's me collected.
When the twin takes off, and passes to 0.8c, we can assume that his
pendulum still marks To = 0 and t = 0.
Pendulum? You mean, clock or wristwatch?
Better yet, which twin paradox and Ariel are you alluding too?

Sorry, Richard, but this is common crank babble.
It’s complaining that accepting relativity is simply religious faith,
rather that a scientifically validated theory. It’s dismissing the
scientific method and saying that people just believe blindly rather than
what they actually did, which is test the idea scientifically.
It’s also crank babble to insist that it’s the obligation of the thinking
mind to question everything, doubt everything, as though nothing is
understood.
It’s also crank babble to say, “If I do not understand it, then nobody
understands it, because I’m smarter than most people, so it’s impossible
that they understand something I do not.”
You are not being at all interesting or unique or original. Instead, you
are repeating all the standard crank babbles.
I'm not saying the theory of relativity is wrong.
I am simply saying that it is very poorly explained.
Take the example of the traveler from Langevin, it is clear (and I do not
even ask myself the question) that the brother will come back younger than
his brother. I don't even need experimentation to find out. I say like
everyone else that the brother will be 18 years old, and the one left on
earth 30.
It is perfectly obvious.
Regarding particles in laboratories, I say the same thing. It is perfectly
obvious.
So no, I'm not criticizing. But I refine, I describe, I demonstrate.
It goes through amputations and pains that hurt men (I have experienced
the same thing in sociology and in theology). Therein lies the main
problem.
For example, this time-gap thing, I don't know where the scientists went
to look for it. It does not exist that. There is NO time-gap during the
U-turn. I don't need this.
Review my little comics on it. You will see that when the twin turns, he
is 9 years old from start to finish, and that the earth is seen there, as
it was at time t = 3 (it has aged three times slower than the traveler at
this moment) and that he still sees it at t = 3 when he reappears on the
other side of the star to begin his return.
There is no time-gap. On the other hand, as Einstein said, and on that, he
is right "space is a reference mollusk". When the traveler turns around
and goes from 0.8c to -0.8c, a relatiistic zoom effect will appear. There
is a colossal space-zoom that falls into place.
This, yes.
The time-gap is the pipe of sincere and honest people who want to explain
things. I wish to believe. But they are wrong.

One needs to read a lot in the literature to sift out the better ones

There are many variants of the twin paradox.
They have a Galilean phases, some have acceleration phases and some have frame
jumping.
There are "time dilation" in each of these "phases".
If the twin paradox scenario under consideration has no acceleration, then there
is no time dilation due to that non-existing phase.
If there are several variants, then none is true, because only one would
suffice.

What is strange is that most of them are broadcast, and that we study
them.

Except mine.

Wrong. By 'several variants' some have the traveling twin travel to Tau
Ceti, others to Alpha Centauri, others to an unspecified location.
Some have the twin take time to turn around, others the turnaround is
instantaneous, others there is a frame jump where the twin meets a third
traveler and gives the time interval to him instead.
They may have different answers but all use the same math, so all are
correct.
Speaking of math, it's always good to remind that your bunch

No, you are all believing in pseudo science. As far as I can tell, you are all stupid.

Here is the real twin paradox, with unnecessary complications stripped out exactly in the tradition of Einsteins thought experiments where he ignores everything he "thinks" is not important.

1. Two twins in a universe devoid of everything except the twins, observe each other and note that the distance between them is growing at a constant rate.

2. STR claims that "the moving twin" will age slower because his time is dilated.

The Paradox is that neither twin can claim to be the "non moving twin" and also neither twin can be assigned as the one who is doing the moving. Each can be stationary or moving but none can prove it either way, so therefore none can be experiencing any time dilation and the other not. If the both experience time dilation, then that requires the existence of a Absolute Time to which the Twins times can be dilating in reference to.

So therefore no time dilation is possible, and thus Einstein's claim of Time dilation is irrational nonsense.

Nope, not at all.

You see? You’ve boiled down the twin paradox to precisely one step too far,
where the misconception of the beginning student kicks in.

You have claimed symmetry between the twins, where in fact there IS no
symmetry. That is precisely the mistake the puzzle was designed to caution
against.

I am allowed to submit a variation of the twin paradox just like others submit their version on how to solve it.
This is the twin paradox mark 2.
It reveals the very same problem that the original paradox highlighted, but sans the unnecessary parts.
the twin does not have to "return" for Time dilation to work, read the theory of SR sometime.
"We" are observing the twins, in every thought experiment it's WE who are the only observers, imagining whats happening from two different perspectives. (obs 1 and Obs2 or the two twins) Try to think like a person who understand something about Physics please. (or even just imagination and rational thought)
You can't plot any paths on your moronic chart that pretends that such a thing as "spacetime" exists, UNLESS you first claim that you KNOW which twin is absolutely the stationary one. and that's impossible here and forbidden in STR anyway.

That link and the excuses it proposes are nonsense nothing new or even rational is explained there.

I gave a revised version of the twin paradox, and that "explanation" is no explanation at all.
The paradox is that Einsteins theory results in a statement that is expressed as:
A>B AND B>A. This is the paradox. This is an impossibility.
My version of the twin story and the original twin story are just stories that draw attention to the above expression.

The negation, for them, of Langevin's paradox becomes criminal indecency.

We are at the same level as a man who has just killed his wife, she lies

fine. There is NO problem."

It is on the same level.

But the most dramatic is that it is the biggest pundits of the theory who

This is totally crazy.

Always, always, always, they will answer: "No, no, there is NO paradox.
It's YOUR bullshit that sees one".

For them, it is quite normal for them that two watches beat each other
less quickly. LOL.

And if you point it out to them by giving them the correct explanation
(notion of effective reciprocal chronotropy, but of proper time however
evolving differently in the two twins due to the sparial anisochrony and
the zooming effects on the distances), they spit you out. the mouth.

It reveals the very same problem that the original paradox highlighted,
but sans the unnecessary parts.
the twin does not have to "return" for Time dilation to work, read the
theory of SR sometime.
"We" are observing the twins, in every thought experiment it's WE who are
the only observers, imagining whats happening from two different
perspectives. (obs 1 and Obs2 or the two twins) Try to think like a
imagination and rational thought)
You can't plot any paths on your moronic chart that pretends that such a
thing as "spacetime" exists, UNLESS you first claim that you KNOW which
twin is absolutely the stationary one.
What are you TALKING about? Why do you think one twin has to be identified
as absolutely stationary to draw a line on a space vs time graph? Do you
not think this is possible in Galilean relativity, where it’s ALSO not
known which one is absolutely stationary?
Post by everything isalllies
and that's impossible here and forbidden in STR anyway.

That's not the twin paradox. That is an example of ordinary time dilation.
In this case, each twin sees the other's clock AT A DISTANCE running
slow. They will see each other's clock running slow by the same amount.
The twins never meet again so cannot do a side-by-side comparison.
In the traveling twin paradox, one of the twins turns around and
returns, and meets the first twin in person and do a side-by-side
comparison. It is NOT symmetrical.
This is the work of someone who can't think clearly.
The Twin paradox is all about the silly contradictions that can arise due to the concept of Time Dilation.
IN that scenario, the author of the paradox was only returning the travelling twin to emphasise the dilemma.
But its not an essential component is it?
Because he is not going to age as fast as the stationary twin irrespective of whether he decided to return home or not.
And because this is a thought experiment, the actual twins don't exist, you know that right? So its only US, the readers of the paradox that get to IMAGINE what might occur, should Einsteins claims be correct.
So it not like we are privy to the experience of the travelling twin when he get home and see his aged brother.
You totally miss the whole point and value of the thought experiment when you get so anally retentive.

If you believe that asymmetry is the solution for the paradox, then simply remove that asymmetry from the scenario, and run the thought experiment again, time dilation still occurs, BUT the actual problem is still there!
The paradoxical aspect is that the claimed lack of ageing can be equally claimed by either twin.
Now in the real world, if i aged slower than you but you also have claimed that it was you who aged slower than I, then we both aged slower than the each other.... and you think that this is not a problem of rational thought?

Ok,
The fact that each twin assuming they never were reunited, and were seperated by say one light year at the end of the experiment, you claim are "seeing each other in the past", as if that would somehow muck up the claim that one is younger than the other. They can still figure out that one has not aged like the other IF Einstein is correct.

No need to return at all. Both know that it is going to take one year for the information to reach them , and that's not the issue here. So they most certainty agree on their ages whilst separated, but they just have to wait for the messages to travel across that one light year.

Here's the thing with Muons. Its claimed that they only have a minuscule lifetime. And how did they figure out that when they only have a tiny fraction of a second to do their observations of one single Muon? Well they don't do it that way. What they did do is akin to this illustration:

Assume that a fish has a lifetime of only a minute, on the basis that when you took him from the water and placed him on you lab bench, he died a minuter later.

Muons are supposed to be travelling almost the speed of light. You almost stopped them in a block of plastic then observed them briefly creating a short trace in a cloud chamber. I submit that you already were observing almost dead Muon's and the lifetime you believe a Muon has is already mostly used up. Its like observing a 98 yo man and saying that men only live 6 months. You don't KNOW for sure that Muon's are only "created" up in the upper atmosphere, they also could be created down at sea level but just not as many. There are lots of possibilities that are not taken into consideration, even the outlandish ideas might be true. Hell, take a look at the magical un-intuitive claims made for QM. Much of modern Physics and Science is based on someone claiming that "We KNOW that such and such" when really there is much that is speculation at best, and a deal of biased beliefs.

So you are wrong to say that its critical that the twins reunite in order to demonstrate some form of paradoxical aspect of Relativity.

Bubble chambers have been around since what, the 1940s? 1930s? You can
see the track of a muon or other particle from when it forms to when it
decays, and from the path length, know how long it lasted. Do that for
lots of muons to get a half-life.
This Muon conservation is not necessary to discuss STR, Einstein never used Muons in his hypothesis yet claimed to have a solid hypothesis. That's what I want to focus on.

Anyway, in the cloud chamber, I watched them for hours, fascinating.
But the CLAIMED cause for those traces does not match their Physics.
You say we can observe the moment of creation of the Muon, and then its extinction. But that is only one interpretation of what we see. You cant prove that this interpretation is correct or that its the only possibility, that's exactly why its impossible to PROVE a theory from experiments.

So the Muon is created, and the Muon has Mass... it is supposed to accelerate to near light speed instantly? No acceleration period? That would require the application of an infinite amount of FORCE from somewhere, to accelerate ANY object that has Mass, to near light speed in ZERO time. (actually impossible) Plus once that object that has Mass (even a tiny bit) but its moving at almost light speed, then according to the equations, it would possess almost infinite MOMENTUM. Almost infinite energy would be released when that Muon collides with any solid matter...

err ... but I never saw that in the cloud chamber....
The energy required to accelerate an object to light speed is infinite, and therefore impossible, so at just a shade under Light speed, even that low Mas Muon would still need enormous application of force, requiring enormous amounts of Energy..... but I don't see that in the cloud chamber....

That is clearly nonsense. You are confusing what it is called "relativistic mass" with mass.
The word mass has two meanings in special relativity: invariant mass (also called rest mass) is an invariant quantity which is the same for all observers in all reference frames, while the relativistic mass is dependent on the velocity of the observer. According to the concept of mass–energy equivalence, invariant mass is equivalent to rest energy, while relativistic mass is equivalent to relativistic energy (also called total energy).

The term "relativistic mass" tends not to be used in particle and nuclear physics and is often avoided by writers on special relativity, in favor of referring to the body's relativistic energy. In contrast, "invariant mass" is usually preferred over rest energy. The measurable inertia and the warping of spacetime by a body in a given frame of reference is determined by its relativistic mass, not merely its invariant mass. For example, photons have zero rest mass but contribute to the inertia (and weight in a gravitational field) of any system containing them.

You are referring to an obsolete concept called relativistic mass. It is
a confusing idea since "relativistic mass" is frame dependent and
changes, while rest mass is invariant. Nowadays what is taught is that
energy has momentum and a particle moving near c has a lot of (kinetic)
energy, which has momentum, which resists further acceleration. The
momentum is the same as that the relativistic mass would have, if you
use that concept. If you have older books discussing relativistic mass,
just multiply it by c^2 to get the equivalent energy.

Yet the Muon can, while NOT gaining Mass to the value near infinity,
It has kinetic energy. Lots of kinetic energy for atmospheric muons
(gamma from 10-20). But not infinite (gamma=infinity).
Post by everything isalllies

Nope. Atmospheric muons mostly come from the decay of pions produced by
cosmic rays. The energy they have is the original kinetic energy of the
pion plus energy from the mass difference between the pion and muon (34
MeV), but this energy gets shared with two neutrinos which are also
formed. The original pion energy can be fairly substantial.
Post by everything isalllies
No detectable force of the Einsteins required magnitude is to be found.. yet Muons are still doing it and our beliefs about Muons is still true.
I wouldn't want to apply classical concepts like acceleration to newly
formed muons. As I said I am satisfied with the idea that they are
"born" with their speed/momentum/energy. Just like a photon, which
never can have a speed other than c. It does not "accelerate" to c when
formed. It can't.
Post by everything isalllies

But they do. They have kinetic energy, which has momentum, which resists
further acceleration. Plus they make a great example of time dilation by
being able to reach the ground even though they should be able to go
only about 600 meters in their own frame.

By your logic we need to eliminate electrons, protons, and (especially)
photons.

Einstein: Any mass no mater how small, will increase in Mass towards infinity whilst consuming all the energy in the universe if it were to attain near Light speed.
A good example of why "relativistic mass" is confusing and not really
used now.

An atmospheric muon does have energy substantially more than its rest
mass equivalent, but the amount it has is that of the original pion
(large but not infinite) + 34 MeV minus what two neutrinos take.

This nonsense is typical of the way your brain has to slip into neutral if you accept Einsteins irrational theories.
The belief that Energy can have momentum, is a perfect example of insanity.
It was developed as a concept to try to overcome the impossibility that an object can gain Mass from nowhere just because someone is watching it move past. (that's the STR in a nutshell)

But to claim that a Property of an Object can exist without an Object, (Energy- the capacity to do work) can then have another Property that is only applicable to an object with Mass, (Momentum) is the height of insanity.
It highlights just how stupid people studying Physics have become, which explains why none of you guys can carry on a decent conservation and use rational thinking.
p=mv, that's the equation you apply if you want to calculate a comparative value for Momentum, and any later claimed equations for Momentum better be in accord with this equation. But they are not. Therefore they are wrong and its easy to see why as explained above.

Your statement, "The momentum is the same as that the relativistic mass would have,"
means that you are claiming that whatever the Mass is, that is also exactly what the Momentum is, therefore your equation becomes p=m or simply Momentum is Mass, same thing.
And "relativistic Mass" does not kick in at some percentage of lights speed, the Mass, if we assume that Einstein is correct, is increasing at any speed, its just hard to detect at lower speeds.

So what Einstein claims is this: And object has a continuously changing Mass linked to its speed as observed from another location from which the velocity was measured.
And to make it even more insane, 500 differently moving observers will all claim that the same objects Mass has 500 different values.

In other words, the Property if an object we have called Mass, is not actually a property of the Object, but is a property of observed speed of the object. We are measuring a property of speed that causes us to get different readings when we measure an objects speed but its not an objective value, its subjective.

Its hard to write about this because its difficult to rationally discuss the thoughts of an insane mind. Insane minds invent irrational ideas. Irrational ideas can't be analysed rationally.

Nowadays what is taught is that
Post by Michael Moroney
energy has momentum and a particle moving near c has a lot of (kinetic)
energy, which has momentum, which resists further acceleration. The
momentum is the same as that the relativistic mass would have, if you
use that concept.
This nonsense is typical of the way your brain has to slip into neutral if you accept Einsteins irrational theories.
The belief that Energy can have momentum, is a perfect example of insanity.
What about light? It's easily demonstrated that light, which is
massless, has momentum p=hf/c and energy E=hf.
Post by Michael Moroney
It was developed as a concept to try to overcome the impossibility that an object can gain Mass from nowhere just because someone is watching it move past. (that's the STR in a nutshell)
"Gaining mass" which is different for different observers is confusing,
so energy having momentum (which falls out of SR) is more understandable.
Post by Michael Moroney
But to claim that a Property of an Object can exist without an Object, (Energy- the capacity to do work) can then have another Property that is only applicable to an object with Mass, (Momentum) is the height of insanity.
Light has momentum without mass.
Post by Michael Moroney
It highlights just how stupid people studying Physics have become, which explains why none of you guys can carry on a decent conservation and use rational thinking.
p=mv, that's the equation you apply if you want to calculate a comparative value for Momentum, and any later claimed equations for Momentum better be in accord with this equation. But they are not. Therefore they are wrong and its easy to see why as explained above.
Your statement, "The momentum is the same as that the relativistic mass would have,"
means that you are claiming that whatever the Mass is, that is also exactly what the Momentum is, therefore your equation becomes p=m or simply Momentum is Mass, same thing.
No, it means p=mv, which you yourself wrote.
Post by Michael Moroney
And "relativistic Mass" does not kick in at some percentage of lights speed, the Mass, if we assume that Einstein is correct, is increasing at any speed, its just hard to detect at lower speeds.
So what Einstein claims is this: And object has a continuously changing Mass linked to its speed as observed from another location from which the velocity was measured.
And to make it even more insane, 500 differently moving observers will all claim that the same objects Mass has 500 different values.
You make my point the concept is confusing. You are just one person
confused by the concept.
Post by Michael Moroney
In other words, the Property if an object we have called Mass, is not actually a property of the Object, but is a property of observed speed of the object. We are measuring a property of speed that causes us to get different readings when we measure an objects speed but its not an objective value, its subjective.
Its hard to write about this because its difficult to rationally discuss the thoughts of an insane mind. Insane minds invent irrational ideas. Irrational ideas can't be analysed rationally.
Just forget "relativistic mass" and use the idea of energy having momentum.

Nope. There are many other kinds of "mass" :

" ...A large number of people or objects crowded together"
" the majority of."
" any of the main portions in a painting or drawing that each have some unity in color..."
" the ritual of chants, readings, prayers, ..."

etc.

You need to understand that words have meanings in context. A word can mean many different things in many different languages.
You must have the brains to know which definition to use.

In physics,
There is what we call "proper Mass" (aka rest mass, or just "mass") and there is
relativistic Mass (a valid *expression* that is fading out).

No, its been thoroughly done away with, because having two definition of Mass is not possible in Physics.
There was always and can only ever be just Mass, to start saying that an Object possess two types of Mass that each have different values whilst at the same time saying that Mass is defined as a Measurement of Inertia, which gives only one result, not two.

The reason why the decided to kill off Relativistic Mass was because its really stupid to claim that a Mass can increase just because some is watching some object move. Where does the additional Mass come from?

Now you most certainly did say that Relativistic Mass is Obsolete. And that's the "approved" statement of Mainstream Physics.
You used the tense of obsolete "obsolescent" suggesting that its "in the process of becoming" obsolete. But that's stupid. The Physics community is hardly going to say from 2023 the idea of "relativistic Mass" will no longer be acceptable in Physics, so in the meantime we can occasionally use it but gradually do away with it.

Did Einstein say when his theory was accepted as fact by the scientists , that they should slowly grow out of the Physics of Galileo and ever so gradually replace it with his Physics?

Wrong. Its "a" twin paradox (and your below scenario doesn't match the essence of the twin paradox).
Post by everything isalllies
1. Two twins in a universe devoid of everything except the twins, observe each other
and note that the distance between them is growing at a constant rate.
OK. Do you realize in your above statement, that each of server has set up a coordinate system!?
You have specified implicitly that they each have done that, that package have their frame.
Alice sees, measures, that Bob is changing position within her frame.
Ditto for Bob.

Now this contradicts the first part of your sentence: "a universe devoid of everything except the twins".
You say it's devoid of everything except the twins. Yet you implicitly say there are also other things, namely the two frames.

moving can be moving inertially or moving with acceleration.

But YOU implicitly said that there are also reference frames. And I quote:

If they can note distances, then they have coordinated their space. They have given a coordinate system or a reference frame.
That is what it means to "note the distance". In other words, they have a certain scheme, a procedure, to detect distances or changes
thereof. This is what your words meant.
Post by everything isalllies

Frames need not be "hard"; in a loose sense, they need not be physical. But if you want to do physics, to do actual measurements, we do need to use physical stuff, "objects". For instance if I want to measure the speed of an incoming car, I don't have to crash physically into it. I can send a specially crafted EM to it and measure the return signal. Nothing material has interacted with us except for photons.
But we did use physical devices like the source, and the reflector (incoming car).

moving can be moving inertially or moving with acceleration.
Correct. Moving inertially typically means without proper acceleration.
Moving with acceleration typically means moving with proper acceleration different from zero.

There's a big difference with coordinate acceleration. You have not specified with acceleration you are referring to in your scenarios.
As I said, you need to be clear.
Post by everything isalllies
In fact STR never includes any allowances for any non inertial observer or any object observed in any frame,
SR allows for non inertial motion (when described from an inertial frame).
Another way to say this, is that SR allows for an object to have non-inertial motion; SR can compute the time displayed on that object
during its non-inertial motion. SR can also describe the motion of this non-inertial object via any inertial frame.
Post by everything isalllies
that is not exclusively moving inertially. If you believe it does, then quote from Einsteins 1905 paper please,
showing where he allows acceleration in his hypothesis or in his calculations.
Let S be an inertial frame.
Consider the set of events (x(t),t).
SR applies to all sets of events thus also applies to the set (x(t),t), right?
x(t) is arbitrary here [well, best to require that it is continuous], thus
including accelerated motion. You can set x(t) = a*t² /2 if you whish.
An object can follow this path. (x(t),t) still Remains a set of events as described by S, right?

There are many scenarios of the twin paradox. Each scenario is different and must be analyzed giving the initial data, the initial scenario.
In some scenarios the twins reunite where one is younger. In some scenarios the twins reunite with the same age. It all depends on the scenario. One needs to stay the scenario clearly at the beginning to do the right analysis.

Claiming things I never said or meant.
You whole argument here is that I said two observers are the only objects in the universe, and they observer a growing distance between them.

You think that there additionally MUST exist two frames of reference because that's the only way the two observers can observe any change in distance.

But this is only because you don't understand Physics.

Do tell me this... it is a very important point... You posited that **The Observers notice** a change of position.
How can they noticed this?
Post by everything isalllies
You think that there additionally MUST exist two frames of reference because that's the only

Correct. That is the **meaning** of Observers.
'Observers' is synonym to 'coordinate system', synonym to 'reference frame', synonym to 'SpaceTime coordinates', synonym to (x,t).

I agree in the Common Street language these are not synonyms.
But in physics, in particular in special relativity, they are (well there are slight different
connotations but they basically mean the same thing and Beyond the scope of our discussion here).

So again, learn the appropriate language else you will not be understood.
Again, I suggest you read the section of servers in the book I referenced you above.
Then there is a similar section in 'spacetime physics' by Taylor/Wheeler. And read up some more to get a proper understanding of the concept of Observers (and inertial frames, etc).

True. We are concerned with what will the measuring device display.
So you are saying in reference frame one, Obs2 is changing positions.
In reference Frame 2, Obs1 is changing positions.

Here, 'ObsX' refers to *persons*m or *objects*, or more accurately, a set of spacetime coordinates.
For instance, in frame 1 (F1), we may have the set of coordinates (x=1,t=1), (2,2), (3,3) etc. These coordinates are "changing".
They may represent the coordinates of Obs2, say.

Is this is what you have been meaning all along?

That is what it means to "note the distance". In other words, they have a certain scheme, a procedure, to detect distances or changes
You are creating a strawman here.
Claiming things I never said or meant.
EXACTLY !!
The point is, the words you use MEANS what I have told you. If you want to discuss physics, you must use its language.
The words and sentences you've been using, are to be taken as per the physics meaning. And the meaning is what I told you above.
Perhaps that is not what you meant but that is what your words meant here in physics.
In the marxism-leninism "the best political system" means communism.
Who cares?

'Observers' is synonym to 'coordinate system', synonym to 'reference frame', synonym to 'SpaceTime coordinates', synonym to (x,t).
I agree in the Common Street language these are not synonyms.
And that makes "confirmed by observations" a synonym of -
"derived from some moronic postulates of an insane guru"
But in common language they are not synonyms.

"...the twins, observe each other and note that the distance between them is growing..."
No rebuttal?
So you agree, and you agree that you contradicted yourself in your sentence!?

You are creating a strawman here.
Claiming things I never said or meant.
You whole argument here is that I said two observers are the only objects
in the universe, and they observer a growing distance between them.
Now you seem to think that this necessitated the existence of OTHER
things in space or in my thought experiment.
You think that there additionally MUST exist two frames of reference
because that's the only way the two observers can observe any change in distance.
But this is only because you don't understand Physics.
A frame of reference is not an object of Physics. Its not PART of any Physics hypothesis.
No, sorry, you’re wrong, as I’ve indicated elsewhere. Conservation of
energy is an example of a physics hypothesis — a law in fact. Kinetic
energy is a key part of that law. Kinetic energy cannot be defined without
a reference frame. Try it.
Post by everything isalllies
Only the two observers are in this experiment. All Physics processes can
only happen to these two objects.
The frames are ABSTRACT devices used to allow consistent observation.
They cant affect the experiment in any way.

Of course. Kinetic Energy is a MEASURE not a THING, not an OBJECT.
And ALL measurements are related to other objects.
But taking a measure does not imply that your choice of where to measure FROM and in what direction, is in itself PART of PHYSICS processes.
You are reifying a CONCEPT.
FoR's are not PART of any observation, they only allow the measurement to have a verifiable origin.

do you think this means, in term of your measure.

No, that’s simply not correct.
Kinetic energy classically is (1/2)mv^2, where m is the mass of a single
object, and v is the speed of that same single object — not relative to
some other object, but to some coordinate system.

If you have a 3-object system, say three pool balls, you can certainly
evaluate the kinetic energy of each ball, like the kinetic energy of A
without saying that v is relative to balls B or to ball C or even to the
table.

Conservation of energy is a real regularity of physics. If you think it
refers to nothing real, then you don’t understand physics, period.

If it helps, physics is NOT the study of material bodies and how they
behave. If you thought it was, then you have a grade-school understanding
of physics, and what you need to correct that is not a logical argument but
a better education in the subject.

the differences were made during the purely Galilean phases. We also said
bullshit of the type "the twin jumps of reference" or "the needles panic
during the U-turn". This is all sad.
There are many variants of the twin paradox.
They have a Galilean phases, some have acceleration phases and some have frame jumping.
There are "time dilation" in each of these "phases".
There are many, indeed; but in the meantime in the real

Yes, I am obviously right.
When you don't understand something, you have to start over on a simple
basis. What must be understood is that the first physicists of the time of
Poincaré or Einstein were not morons or terrorists of thought. They saw
very well that this story was wrong somewhere and many were those who
precisely posed what is still called Langevin's paradox today.
There is bound to be an absurdity in saying that two watches move on each
other. It's so obvious that you don't even have to discuss it to be
convinced.
It is absurd in fact.
Yet increasingly precise experiments have shown that the theory is valid.
The question today is therefore: how can an absurd fact come out of a
theory that is nevertheless valid. I worked on it for a long time
(decades) and I found where the theoretical problem came from.
I'll tell you one thing: often, when you don't understand a problem, it's
because the question is poorly asked. In this story, I see with perfect
evidence that it is the confusion that men make between the proper time of
the two twins and the chronotropy of the two frames of reference. It's not
the same thing. The proper time of the star twin will ultimately be
smaller than the proper time of the twin on earth. That is to say what is
written on the watches.
But what is written on the watches, even if it is PARTLY dependent on
chronotropy, symmetrical constant effect of type sqrt (1-v² / c²),
is not all of the time matches or mismatches. Anisotropy also plays a
role.

I put back to understand, the following small diagram.
Note for example that t = To = t'= To' = 0 when all the watches are
triggered.
We see that the watch O notes t = 0 for the event E, and that the watch To
(which represents the local time marks -15 for E). In the other frame of
reference R 'things are roughly the same type. The watch O 'marks t' = 0
for E, and the local time watch marks To '= - 41 for E.
But that's not all. Imagine that a second event takes place at the same
place in R six nanoseconds, or six seconds, or six light years later
(depending on what time we took initially). We will then note for E in R:
(x, t, z, To, t) or
for this second event (12.9.0, -9.6) instead of (12.9.0, -15.0). And in R
'we will denote (32,9,0, -31, 2.24154) instead of (40,9,0, -41,0).
This means that if in R To and t remain identical (the time t of the watch
placed in O and To the local time), it is no longer the same thing in R
'because, there, the event E2 n' will no longer take place at the same
time for t '(in O') and O ".
We will have t'2 = 2.24154 and To'2 = 10.
However, the two watches are in the same inertial frame of reference R
'and it is clear that they therefore have the same chronotropy.
What causes the two watches to not note the same time? Because in R', E
and E2 do not take place at the same place. The anisotropy plays fully on
the proper times of the watches, even if the chronotropy of these same
watches is identical.
It's clear?

Richard, break the problem down. There are TWO questions involved in this
puzzle.
1. Why is it not a paradox?
No, it’s not.
2. What is the explanation for why one twin comes back younger
The traveling twin doesn’t come back younger.
Well, if that were true, then you wouldn’t have a paradox to complain
His clock second contain a larger amount of TIME than the stay at home
clock second.....that means that clocks in different frames accumulate
clock seconds at different rates and thus when they meet again they show
different number of clock seconds. This does not mean that the traveling
clock is younger. It means that the traveling clock accumulated Tt
seconds contains the same amount of TIME as the stay at home clock
accumulated Ts seconds. IOW, a clock second on any clock does not
represent the same amount of TIME in different frame and that’s why when
the twin meet again they show different accumulated clock seconds but
these different accumulated clock seconds contain the same amount of TIME.
The answer to the first question is defusing the mistake that generates the
apparent paradox. The mistake is specifically this: “But snce motion is
relative, it is a completely symmetric scenario. The traveling twin can
think of himself as moving and the earth twin as moving away and then
moving back.” The mistake is — specifically — thinking that it is a
symmetric situation when it is not. Remove the symmetry and the apparent
paradox dissolves, because if it is NOT symmetric, then you cannot make the
claim that you can just reflect the situation as the earth twin moving away
and coming back toward the traveling twin.
question 1.
If you need further response about why it is not symmetric, that can be
described in multiple ways. The symmetry of the situation would require
both observers to be in inertial motion, when ONE is clearly not. Describe
that as “one twin feels acceleration and the other not” or equivalently
“one is at rest in a single inertial reference frame, while the other is
not” or “the worldline of one twin is straight while the other is bent”.
These all MEAN the same thing, using different words. If you don’t
understand how they can mean the same thing, that’s because you do not
understand connections like experienced acceleration and bends in a
worldline. And that you could only fix by READING.
This still doesn’t answer question 2 for you, which comes from
straightforward calculation with Lorentz transforms. But first you have to
understand the answer to question 1.

So you believe watches are mechanically distorted because of velocity?
No, the watches are in their normal state in all the repositories. They
simply beat each other less quickly (ie the one I'm looking at beats less
quickly than mine) by relative effect.
If I move at v = 0.8c, and I look at a watch at rest, or vice versa, a
strange but real phenomenon appears due to the nature of time. It will
appear to me to beat six seconds while mine beat ten seconds.
For her, the effect is the opposite. She looks at my watch in astonishment
and notices that on the contrary, it is mine which beats by six seconds
while hers beats by ten seconds. It is a phenomenon that should be taken
for granted and scientifically established. The fact remains that this
poses, in the end, a huge paradox that most scientists have exposed to
criticize this theory. The problem is that today, in 2022, we still do not
know how to respond correctly to this paradox (except me for decades).
We do not understand that there is a need for the local time differential
To and the proper time of the watch t.
Yes, chronotropy is reciprocally weaker "elsewhere". No, this does not
affect the final consistency of the theory if we do not forget that there
is also another effect: universal anisochrony and that the equation To '=
To / sqrt (1-v² / c²) is only part of the correction to be made to the
two (or more) travelers.

Chronotropy: "The rate of muscular contraction, especially of the heart."
Yes.
Chronotropy (in relativistic physics) : frequency of a given rhythm,
speed at which the watch hands turn.
You are confusing relativistic physics with your private armchair
philosophy.

It is a term that you invented because simply doing the actual physics that
works would not make you special and worthy of attention (in your mind).

You are very likely mentally ill, Richard.

x' = (x - vt)/sqrt(1-v²/c²), t' = (t - vx/c²)/sqrt(1-v²/c²)
The twin's movement according to the stay-at-home twin is x = vt, so
t' = (1 - v²/c²)t/sqrt(1-v²/c²) = sqrt(1-v²/c²)t, not the inverse that you assert.
It's useless to ascribe a mechanical explanation to the so-called "paradox.".
I don't understand the way you put it.
In Langevin's reasoning about the traveler, we have to cut things into
four parts.
The first part is the one where the terrestrial twin sees his brother go
to a star placed at 12 al. It could be Tau Ceti.
The journey takes place at a constant Galilean speed of v = 0.8c thanks to
new technology.
The second part is where the earthly brother sees his twin coming back to
him (this is called the return phase).
The third is the vision of the outward journey by the traveler himself,
and the fourth is the vision he has of his return journey.
In these four descriptions, only one and the same equation should be used:
t'= t (1+cosµ.v/c)/sqrt(1-v²/c²)
where t is the natural time of one of the twins, and t 'the time measured
by the other observer.
Always, always, always, you will come across this simple and devilishly
precise equation.
I don't mind people despising it, rejecting it, not believing it.
LOL.
You will not change the reality of the eternal equations.

Nope. Something else happens between the outward journey and the return
journey: the traveler JUMPS FRAMES. This can be accomplished by the
traveler decelerating and then accelerating in the opposite direction, or by
passing his clock information to a third person already traveling in the frame
he jumped to.

Neither will you change the universe. Either your theory agrees with it or it doesn't.

"It doesn't matter how beautiful your theory is, it doesn't matter how
smart you are. If it doesn't agree with experiment, it's wrong."
-- Richard P. Feynman

And all the extra claptrap you've tossed in does't change the fact that the simple
Lorentz transform is sufficient to solve the so-called "paradox." Occam's razor
says that the simplest solution that solves the problem is the right one. The Bible
says, don't go whoring after other gods.
