But if Observer A then tries to calculate the coordinate relative velocity that Observer B should calculate, it turns out to be v*gamma^2. So there are very observable consequences. Inconsistent and contradictory consequences.

No, That's a wrong assumption. A and B each measures a different [V[ cbecause their clock seconds have a different TIME content.
You assumed wrongly that a clock second is an absolute unit of time......it is not.
A clock second on the A clock /= a clock second on the B clock.

Consider a distant observer traveling at .867 c ( ฮณ=2
) relative to the solar system along the line that is collinear with the
sun's axis of rotation. As the clockwork solar system spins beneath him,
the distant observer peers through his powerful telescope at Big Ben in
London. After taking relativistic doppler into account, the distant
observer measures Big Ben's little hand to make one revolution for every
two revolutions of his own wristwatch's little hand, in accordance with
special relativity. He also observes that Big Ben's little hand still
makes 730.5 revolutions for every revolution that the earth makes around
the sun. From these two observations the distant observer concludes that
in his inertial frame of reference the earth's orbital velocity is only
half the velocity necessary to keep the earth in stable orbit around the
sun.

Will the earth spiral into the sun? If not, why not?

Note: Newtonian gravity is not assumed in this paradox. Invariant
spacetime curvature is assumed to be the cause of the earth's orbit.

Dr. Hachel, may I suggest that you appeal to the generous spirits of Python and rotchm, who I believe are Frenchman and French Canadian respectively, to translate the Big Ben Paradox a la francias. They have a command of both the English language and the Big Ben Paradox. I believe that Athel also has a command of your language and is also a keen student of the BBP.

If we admit that the rocket passes very far (say a thousand light years
from the earth) and transversely, we can imagine that it will have time to
remain transverse long enough to measure the effects of slowing down time
by 2 for quite a long time.

Moreover, the perimeter of revolution of the earth around the sun will be
smaller, because if the Oy axis is invariant, everyone knows that the Ox
axis will be halved.

We will have a period twice as long (it apparently turns less quickly) and
on a shorter circumference.

These two effects, if they were real, would favor a fall of the body in
the center of the system.

However, it is quite obvious that it is not because an extraterrestrial
rocket will pass 1000 light-years from the earth that the earth will
decide to fall on the sun. It's absurd.

So yes, the earth will appear to rotate half as fast as a period of
revolution, and on an ellipse a=R and b=R/2.

But that is only an appearance.

Let's take the problem differently. Suppose the rocket is hurtling towards
the earth at 0.8c. We imagine that the earth's orbit is drawn on a piece
of paper on the table and the rocket descends from the ceiling towards the
plane of the orbit drawn.

The rocket does not perceive any contraction of the distances, since it
approaches the plane without transverse displacement. The orbit is intact.

But on the other hand, terrestrial watches rotate three times faster, and
the earth rotates three times faster around its orbit.

It is obvious that if it were real, at this speed three times greater, it
would leave its axis. v'(tang_app)=v(tang).sqrt[(1+v/c)/(1-v/c)]

These are only effects of perspective.

R.H.

Thank you for your insights, Dr. Hachel. BTW, I notice that your posts to Sylvia continue to demonstrate an increasing warmth of sentiment and, dare I say, romance. Please keep this forum informed in the event of an engagement and/or nuptials.

It is not an assumption, Stupid Ken. It is what SR derives from its two
postulates.

A and B measure the same v but in opposite directions. They have the
same magnitude |v|.

No, Stupid Ken, time is measured in seconds which is defined as the time
of 9192631770 Cs transition cycles.

No, Stupid Ken. Each of those statements come from the scientific
method. All scientists need to follow the scientific method if they wish
to create a valid scientific model.

The lack of a TOE is irrelevant. It just means nobody has discovered a
valid TOE so far. And apparently any such TOE will not be simple.

no, I challenge you, It needs to be circular, hence repetitive. The
detectors at start would necessarily coincide with those at the end. The
credit of america ๐—ฑ๐—ผ๐˜„๐—ป๐—ด๐—ฟ๐—ฎ๐—ฑ๐—ฒ๐˜€_๐—ณ๐—ฟ๐—ผ๐—บ_๐—”๐—”๐—”_๐˜๐—ผ_๐—”๐—”+. This is amazing. It looks
like an underdeveloped country.

Stupid Mike, it is a wrong assumption because the SR postulate (P2) is wrong.

No they don't get the same result because three clock seconds have different value of time.

You assumed wrongly that a clock second is an absolute unit of time......it is not.

No stupid Mike, you assumed wrongly that each cycle of Cs have the same interval of TIME.....they do not
Each cycle depend on the arrival of specific amount of energy and the arrival of this energy
is dependent on the absolute motion of A and B. Since A and B are in different states of
absolute motion, each cycle will take a different interval of time (absolute time) to arrive and thus a different amount of time (absolute time) to complete a cycle of Cs.

I did not say I can detect absolute motion. I merely describe, according to my model, w,ha,t causes

It predicts the result of observing the ticks through a telescope, and
measuring the interval between them. The relativistic Doppler effect
formula gives the answer.

A postulate cannot be wrong. A postulate is a postulate.

They have the same value of time because the second has an exact
definition, Stupid Ken. In addition to symmetry arguments for the
velocity having the same magnitude.

Stupid Ken, your assertions are not valid arguments. The second is
DEFINED as that many Cs transition cycles. A definition cannot be wrong.

Your assertions are not valid arguments.

There is no such thing as absolute motion in any science model. All
motion is relative.

> Since A and B are in different states of

No such thing as absolute motion in any model of science. Therefore this
clause is meaningless nonsense.

> each cycle will take a different interval of time (absolute time)

Because the first part of the conditional clause is false, this blather
can be ignored.

> to arrive and thus a different amount of time (absolute time) to complete a cycle of Cs.

More blithering word salad.

Since your Muddle Mechanics is dependent on something that doesn't even
exist, it has no value whatsoever, so it is ignored.

And do you still believe that 9 192 631 770 ISO idiocy
is some "Newton mode"? You're such an amazing idiot,
stupid Mike, even considering the standards of your
moronic religion.

Stop lying, stupid Mike, the definition of second is varying.

Of course it can, stupid Mike. Your assertions are not valid arguments.

stupid Mike, what does the following equation mean to you?
1 second in frame A= 1/gamma second in frame B
Does it say that a second in frame A=a second in frame B?
Gee you are stupid.....you have no idea what is TIME.

In current kinematics, there is a longitudinal Doppler effect (for example
the Doppler effect relating to sounds).
But in relativity, it is difficult to speak of a single Doppler effect,
because there are two.
There were also two in classical mechanics, but the second effect is so
weak for low speeds (gamma factor) that it is rightly ignored.
I think (not out of arrogance, but out of love of what is true) that it
would be better on this point to adopt my terminology.
I call longitudinal relativistic effect the effect of the first degree due
to spatial anisochrony (or speed of light).
I call INTERNAL relativistic effect the effect of the second degree linked
to the relativistic factor gamma.
I refute the idea of transverse Doppler effect which leads to confusion.
When I see a rocket arriving at me, its displacement is purely
longitudinal (cosยต=-1).
It therefore has a longitudinal Doppler effect of the first degree.
But it also has a "transverse" Doppler effect as it does not move
transversely in any way. The term therefore seems to me liable to
misinterpretation. I therefore prefer the term INTERNAL Doppler effect.

These two Doppler effects are cumulative.

The object which moves in space will therefore undergo two Doppler effects
and the residual equations will become for the apparent speeds, for the
perceived proper durations, for the perceived lengths, and for the
received wavelengths.
Vapp=Vo/(1+cosยต.Vo/c)
t'=t.(1+cosยต.Vo/c)/sqrt(1-Voยฒ/cยฒ)
L'=L.sqrt(1-Voยฒ/cยฒ)/(1+cosยต.Vo/c)
lambda'=lambda.(1+cosยต.Vo/c)/sqrt(1-Voยฒ/cยฒ)

Notion of relativistic Doppler effects, my love Sylvia.
