Two physical events are said to be simultaneous when they occur at the
same time, when they happen at the same instant.

But FOR WHOM?

A misunderstanding seems to have existed for many decades, probably since
1905, in the minds of scientists.

They seem to think (but maybe I'm wrong) that the notion of simultaneity
depends on the inertial frame, and that jumping from frame to frame I will
no longer simultaneously perceive previously simultaneous events, i.e.
that E1 and E2 will no longer occur at the same time.

This is completely wrong.
The notion of simultaneity, on the contrary, and this is the genius of the
properly understood theory, is remarkably and rigorously invariant by
change of frame of reference.

All the events of the universe for an observer remain remarkably
simultaneous for another observer who will cross it with a speed of 0.6c
or 0.8c.

What scientists confuse with the notion of simultaneity is the notion of
chronotropy.

Admittedly, the hands of the watches will reciprocally beat less quickly
when one looks at the other watch.

But that is the notion of measuring time, the notion of chronotropy.

Not the notion of simultaneity.

The two observers will apprehend, at this joint moment, exactly the same
universe, the same present world.

Obviously very distorted spatially because of the spatial component
x'=(x-v.To)/sqrt(1-v²/c²).

But the same universe "currently" visible.

It is this strange misunderstanding that is embedded in the minds of
scientists like a bit in the jawbone of a horse that I have been
denouncing for years.

On the other hand, a misfortune never arriving alone, to compensate for
this error of concept, the scientists will create another: they will
imagine the chimera of the "plan of the present time" in a given reference
frame.

The error will then become total.

They will miss the magnificent notion of universal anisochrony: you CANNOT
synchronize two inertial watches together.

The notion of simultaneity no longer exists for two observers not present
in the same place.

For all the events of the universe to be simultaneous, it is necessary
that the observers (fixed or evolving at relativistic speed) are in the
same place.

Any distance in space immediately introduces an anisochrony of t=x/c.

Romeo and Juliet only really coexist together when they are in the same
bed.

No. Both Poincaré and Einstein seriously asked the same question,
thought carefully about it and ended up with similar answers.

Since then a lot of people have been considering this problem too,
especially to spot what is conventional and what is not in
synchronization procedure, and why they are needed.

The only confused mind here is yours Richard, for at least 30 years.

The problem with manipulative personalities is that they often manage to
pass themselves off as victims.

And they accuse those who are right of being confused.

Jean-Pierre Messager will explain to us how it is, for example, that he
can tell us that he is not confused in the bullshit he tells and that he
probably believes to be right.

I asked him many times to explain to me how he managed not to be confused
by studying a simple Langevin in apparent speed (ie what I see in my
telescope, and which is "something").

I have as always, and with ALL the "representatives" of the "exact
doctrine" heard the sweet song of the cicadas of the cicadas in the
distance.

I swear to you: with ALL!

But I know where the problem comes from, it is theological.

"We will never be able to put our faith in a guy who is all alone on the
scales and all the science on the other. He is necessarily an idiot who
speaks like Aznavour was an idiot who sang".

He's not confused, Jean-Pierre.

He is strong.

It explains very well how it is that a rocket heading towards me at 0.8c
can be observed with an apparent speed of 4c.

He is not confused.

He knows.

Problem, I'm not confused either, let alone him, because I've pondered the
question for decades.

And he will explain to us that the proper time of the traveler will be 9
years.

That is to say that for 9 years, he will see the earth come back towards
him with a speed of 4 c.

The problem will come when we ask him the question: "but over what
distance, then?"

It is not confused Jean-Pierre.

Sometimes, he makes you laugh so much that you almost find him funny.

Bunches of freaks!

Crazy bunch!

You are a psychopath, Richard. Being wrong on math or physics
is not that a big deal, you are nobody. But the pathological
habit you have to consider better than anything, including
scientific studies, whatever you've pulled out of your ass
(i.e. shit), is a problem because you are M.D. And having
such a state of conduct as an M.D. can hurt or kill people.

You should have been forbidden to practice for years, probably
from the very beginning.

J'ai pas trop le temps de faire des cadres, et je préfère y mettre des
chats ou de beaux visages,
mais si j'avais le temps, je mettrai des belles coquilles manuscrites.

Celle-là, venant de Jean-Pierre, est particulièrement croustillante.

Il est de plus en plus fou.

Je persiste néanmoins à lui demander comment il fait pour multiplier 9
par 4 et trouver x=7,2

Je trouve sa mathématique "confuse" et réciproquement.

Ca doit bien faire une dizaine d'années que je lui demande (comme aux
autres d'ailleurs), et, qu'en réponse, j'entend toujours que le doux

Mais bon, admettons.

Oh, stinker Python is opening its muzzle again,
and trying to pretend he knows something.
Tell me, poor stinker, what is your definition of
a "theory" in the terms of Peano arithmetic?
See: if a theorem is going to be a part of a theory,
it has to be formulable in the language of the
theory. Do you get it? Or are you too stupid even for
that, poor stinker?

For all. A matter of a convention respected globally.
Like TAI. Or UTC. Unlike the idiocies of your insane

Given a reference frame which has been coordinated, two events are said to be "simultaneous" when the clocks
located at the events in question indicate the same value.

It does depend on the inertial frame by definition of " simultaneity".
Just apply the definition. That is what the word means.
If you are thinking of something else, use a different word.

Nope. Just apply the definition. You do know what a definition is, right?

You are then thinking of some other notion. Use a different word than "simultaneous".

Can you translate that into the appropriate language (english) ?

Or, are you just spamming?

If I define a shark as a 4-legged grass eater -
will sharks start to eat grass, poor halfbrain?

Your question does not follow. Insufficient information.

However, since a cow is a four legged grass eater, then that animal (cow) would be a shark.
This terminology is valid for our discussion since you defined your word(s).

In different contexts, words have different meaning. Didn't you know this?
(Yes you did since you agreed to it in the past)

Doesn't your "if you are thinking of something else, use a different word."
apply?
Well, yes, it does. But it's your idiot guru and you who should use
different words. The meaning of "time", the meaning of "simultaneity"",
the meaning of "second" - they all existed before and they were different
than your definitions say.
And they still are. You believe you have the power to distort any meaning
of any word you want to. You're such a bunch of arrogant idiots.

Don't force your whishes onto others. Learn some respect.
If you choose to come here, use *their* rules.

And this is also true for most words you use.
The meanings of words change throughout history. Didn't you know this?

And you do this too (but you are too stupid to be aware of it).
I use the meanings as defined in the context. Can't you do that?
When I immerse myself somewhere, I use their rules. Can't you do that?

This is one of the biggest bullshit I've ever heard from a guy who
understood the theory of relativity.

Relativity says exactly the opposite, and if it does not say so, it is
because it is badly explained.

If I synchronize two similar watches and I separate them both in the same
way and on the same distance, but opposite, they will NEVER simultaneously
mark the same time between them.

Each will advance on the other in a real and physical way by a value of
T=x/c.

This is called spatial anisochrony.

The "present time plan" is pure nonsense, nothing, a mental chimera.

Its a definition. Don't you know what a definition is? Whats its purpose, its use?

I've now told/explained it to you. Now you should know.

You are confused. We were not talking about synching watches. We were talking about
the *simultaneity* of two *events*. See your first sentence of your OP.

"synchronize two similar watches and I separate them"
has nothing to do with your OP; it has nothing to do with simultaneity.
Try to remain on topic.

OK, whatever. I don't see the use of saying this, and is off topic.

In the context of marxism-leninism and its definitions communism
is the best.
In the context of creattionism and its definitions God created
species.
In the context of The Shit and its definitions time dilates. Sure.

But in the meantime in the real world, forbidden by your

serious clocks always did.

Of course. I could easily use their shitty rules and help them to

Then how about I go to you, in your room where you are sitting.
I will impose my rules onto you. How would you like that?

No answer? (requires a yes/no answer).

I did not shape/define them. I use the ones as defined in this NG; that's respect.

SR correctly predicts the values displayed by clocks.
But you have shown to be a reality denier.

Nope. Even Newton noticed & said t' <> t.

A lie from The Fanatic trash you are. Above you said you will not use their rules and now you say you do.
You just contradicted yourself.

But you can't since you do not have the mental abilities to do so; you have zero math skills, 0 reasoning skills and a big deficiency in the language you use... And you are a reality denier.

Oh, stinker Python is opening its muzzle again,
and trying to pretend he knows something.
Tell me, poor stinker, what is your definition of
a "theory" in the terms of Peano arithmetic?
See: if a theorem is going to be a part of a theory,
it has to be formulable in the language of the
theory. Do you get it? Or are you too stupid even for
that, poor stinker?
