#595229 — Proper time and relativity

FromRichard Hachel <r.hachel@frite.fr>
Date2022-11-12 09:42 +0000
SubjectProper time and relativity
Message-ID<D0oArXlGADk_mv6eiLyfZ4Ncwn4@jntp>
Hachel's principle.

"If two relativistic mobiles travel, in equal observable times, identical 
paths, their proper times will remain equal."
 
It's a very simple sentence that I think is quite correct.
 
Yet this principle deeply shocks all relativist physicists in the world.

Baez crackpot index:

3. 2 points for every statement that is clearly vacuous.

25. 20 points for naming something after yourself. (E.g., talking about 
the "The Evans Field Equation" when your name happens to be Evans.)

If you knew how much I don't give a damn about Baez's bullshit, who 
whistles well, but never sings.

And don't forget to add your fellow idiot Tom 5 points

There is only one proper time, ...

de other guys watch don't count.


If you're wearing two watches, which one has the correct time?

No. There is more than one time at a black hole.
Time ends and starts over...

In other words, If I'm wearing two watches, in equal observable times, and I'm traveling in identical
 paths, which watch has the proper time?

the other one. Here you have, for instance, a lying polaker bitch in 
*8_seconds*. A lying polaker before the entire world, on record. These 
modrafaka bitches had *extermination_camps* on their territory, before 
Hitler entered the shithole.

https://%62%69%74%63%68%75%74%65.com/%76%69%64%65%6f/X3Ol7JjMFqPO/

It doesn't matter. Pick one and tell me why the other one doesn't
show the proper time/

What is "observable time"?  What does travelling "identical paths" mean?
Just the trajectories are the same?  Or the trajectories and the speeds
at every point of the trajectories are the same?

In physics proper time is the arc length of the trajectory when plotted
in the 4D spacetime.  This means proper times of the two object are only
guaranteed to be the same if their entire movement is the same (same
3D paths in space with identical speeds at every point of the path).

But this is just a generic well-known fact, not any "Hachel's principle".

> It's a very simple sentence that I think is quite correct. 

As stated it's neither correct nor incorrect, it's actually not even wrong
due to its use of undefined terms.

> Yet this principle deeply shocks all relativist physicists in the world. 

Nobody is shocked, trust me.

Of course it is, it's shocking, because that's not what the theory of 
relativity as taught says.

I talked about it for a long time with several people here.

They all consider that proper times will no longer be the same.

I take the well-known example of Tau Ceti.

We're going to arrange for two rockets (it's a thought experiment), 
leaving at the same time, from the same place.

They start from the ground, and will connect Tau Ceti (12ly).

One starts according to the accelerated example that we have long treated 
here, and which is 10m/s².

Let a=1.052 ly/y² as Stan Fultoni rightly points out.

The other will start with a constant real speed of 2.5122c.

They will cross the same space, and arrive at the same time.

Don't forget what Hachel says (that's me): "events coinjoint in one frame 
of reference are cojoint in all".

If they leave at the same time, they leave at the same time in all the 
observing reference frames.

If they arrive at the same time, they arrive at the same time in all the 
observing reference frames.

I don't even have to explain it, it's so trivial and obvious.

I then said that the path being the same, the observable time (ie 
terrestrial) being the same, the proper times will be the same.

We come back to the dramatic error that Stan makes (because he learned the 
theory from the mouth of his teachers) and which is to believe that the 
proper times are much shorter than I say in the accelerated frames of 
reference.

The error is there.

Stan makes a conceptual error in his integration, not in the calculation, 
I always have the same answer as him no matter what I integrate.

But the problem is not there.

You can't integrate, and it doesn't work that way.

Just as one cannot add relativistic velocities together as Galileo or 
Newton would have done.

Do you understand what I'm explaining?

I'm not asking to be believed. I ask, at least that we understood 
perfectly what I wanted to say the day when the experiments will be able 
to show that indeed, certain things are wrong.

However, their paths between those two events is not the same in all
reference frames. The first rocket travels along a curved path in most
reference frames. The second rocent travels along a straight path in
every reference frame.

When I talk about the same path, you will notice that I didn't use the 
confusing term "trajectory".

The term trajctoire can be confused with the term trajectory in 
space-time.

I'm not talking about that.

I beg you to read carefully what I wrote.

Nobody reads right, although I write right, and very careful what I say 
because I know it's hard on your indoctrinated brains.

You don't want to get out of it, and for that, you make me say what I 
didn't say.

I repeat it once again (even I have a feeling it's going to be useless):

They will cross the same space, and arrive at the same time.

I didn't say "the same space-time".

Please, be awake and lucid.

And that's your mistake.

They don't follow the same paths through spacetime.

An observer will see the constant speed traveler move ahead of the 
accelerating traveler, then the accelerating traveler gains speed and at 
some point the distance between them is no longer increasing and then it 
starts decreasing, until the distance reaches 0 at the destination.

At no point other than at the start and end of the journey are the two 
travelers at the same location at the same time.

Obviously different paths through spacetime.

 Et mes couilles, elles suivent le même chemin, dans l'espace-temps?

 J'ai beau les supplier d'arrêter.

 Ils continuent.

 Que puis-je faire?

 Je les supplie, une fois, deux fois, trois fois, d'arrêter...

 Ils continuent...

 Mille fois, sic mille ans... 

 Quoi faire?

 Suis-je Superman? 

 Non, je ne suis pas Superman. Je ne viens pas de Krypton, et je ne vole 
pas dans les airs.

 Cela, ils ne le comprennent pas. 

 Merde, c'est pourtant pas con à comprendre.

So you agree they don't take the same paths through spacetime.

Does he also agree that adjusting clocks
to your ISO idiocy means putting them into
some "Newton mode"?

Yes my love.

That's what I keep saying.

They follow the same path, in space.

But not in space-time, since I begged millions of physicists to tell the 
difference (but they're too dumb, it's horrible).

Shit!

I have been begging people for years to be very careful with the words, 
and the dogmas they use.

They spit in my face.

So yes, my love, that's what I say, the same path.

Not the same "4D trajectory" that I don't understand, because I don't care 
about your bullshit of bullshit.

I am talking about the same spatial trajectory in the observing frame of 
reference.

The other bullshit and stupidity, I don't care.

OK, so your statement from your first post is false then.

Stop fantasising about experts' stupidity. You'll get
nowhere using this method of discourse.
