When I toss a ball up it is bounced back in my hand with certain
velocity. If I do that in a train compartment, always tossing with
equal force, whatever might be the velocity of the train, there is
never a change in velocity of the ball. Why?
I now toss up a pulse of light on the mirror and I always receive the
pulse with unchanged velocity c at the source. Why?

Yes, a "certain" velocity that has the same magnitude as the
ball had when you tossed it.

You always *are* in a "train compartment", so to speak. You have
never been in some kind of "absolute rest".

Why would there be? You always are in a train compartment.

You cannot *toss* pulses of light. You can *release* them.
Tossing means that you can influence the speed by varying
the "amount of toss". You can't do that with light.

OK, I will search meaning in your answer. ‘All inertial frames are
equivalent’. Now tell me why they are equivalent. Why any mechanical
experiment, such as tossing up a ball, cannot detect velocity of the
train compartment?

Light is not waves predicted by Maxwell. They are photons. That is why
I used a light pulse. Such a pulse with narrow length can be produced
by lesser. First you must come to the conclusion if this light pulse
behaves like a ball and if the observer in a train will always measure
its velocity to be c.
I will not buy the argument of Dirk that for an observer in the train,
he is always at zero velocity. He can accelerate and knowing the
acceleration he can predict his new velocity. For a ball this new
velocity is undetectable. I asked why. I want specific answer.

No idea.
This fenomenom has been given names like "inertia" but that
doesn't really help much. It's just a name.
*Why* nature behaves that way, seems to be a question for
which we have no solid answer. There's lots of questions
without solid answers.

Why not ? His point is very clear and correct. You are never at rest,
you and the ball are always moving. Standing on a moving train is like
standing on the Earth.

So why is he avoiding the answer? Ball cannot detect velocity of the
train because as you have pointed out, ball is also moving with the
train. This is the reason why all mechanical experiments are
equivalent in all inertial frames.

It appears to me that all are averse to discuss the question I raised
for fear of shaking fundamental aspect of SR. So I would like to make
my argument.

I do not wish to discuss here, whether light is ballistic or not. If
light is ballistic then it would behave like a ball and so even for
light all inertial frames would be equivalent. But in that case, MMX
needs no explanation and there is no need for SR.

In case light is not ballistic, then inertial frames are not
equivalent and it is easy to detect motion of any frame based on
absolute velocity of light. But in this case detected velocity of
light would be c+v and c-v. In this case too SR will have to be
dumped.

Some illustrious posters have argued that there is no difference in
the frames. This is true in terms of relativity. However a passenger
can always perform the experiment, while stationary and then after
accelerating to some constant velocity. Problem with relativity is
that it doesn’t deal with such a reality. Of course stationary
observer will easily detect this velocity but actually this is not
necessary. Based on knowledge, a passenger can find out if light is
ballistic or not. If it is ballistic then he will not be able to
detect his own uniform motion.

Some have argued that, SR is based on two postulates. However
postulates cannot ignore known facts. Extraordinary postulate can be
made in case of unknown. For example postulate of ether to explain
wave nature of light. But ether was rejected as it would require
abnormal properties. Here we are dealing with something within our
knowledge of something and that which can be proved. A very small
pulse of light can be generated and it does have finite velocity in
space. Once we know this, there is no other way but to treat this
pulse as a bunch of photons. It is madness to treat light as both
Maxwell’s wave and photon simultaneously.

The only question remains is that of nature of light which gets itself
propagated at a constant velocity. Whether it is source independent or
not has no relation to the postulates. If light is ballistic then
Einstein’s 2nd postulate is wrong and if it not then his 1st postulate
is wrong.

Do you understand that your experiment is poorly worded, right?
First, you affirm that "there is never a change in velocity of the ball".

There are at least two physical problems in that phrase. Can you recognize them?

He means there is no change in the horizontal velocity of
the ball relative to the track, moron. Of course there is a change
in the vertical velocity, it changes direction as he stated, imbecile.
You are an idiot. Can you recognise yourself?

No it isn’t a different situation, papabozo. It is clearly the same as the ball experiment, you stupid fuck.

That is the problem. You show *no understanding whatsoever*
of physics 101 (which means level age-13) and you are here to
make arguments about a topic of advanced physics.
You don't have the background, you don't have the maturity, and
you don't have the mind-set for having such discussions. Go to
school, do some real hard work, and come back in 10 years of so.

More likely, there simply isn't much interest in a tosser like
Vilas Tamhane, whose knowledge is so pathetically poor that he
wasn't even able to form a coherent question about the topic.

No one does that. Classical and quantum electrodynamics have
separate domains. Both, as conventionally formulated, fundamentally
rely on the ideas of special relativity. But we can expect that
rather than learning about them, you will continue being a tosser.

So you were wrong there, then.

> But where are your answers?

Just in-between your text above, rather nicely. Di'nt see them?
Ok, yet another, if vain, try:
each inertial observer sees light "pulsing" at c.
each of them sees other observers as if using length contracted rods and
time dilated clocks for their measuring, thus however reaching the same
result for c.
two observers assign the same contraction and dilation values to each
other's frames.
this implies of course that they don't operate along coinciding lines of
simultaneity.

See the mutuality of the transformations:

I am not talking about two observers. I am talking about one observer.
I am speculating on his observations in two different frames. We know
that the frames are different and the passenger can safely arrive at
this conclusion from the record of acceleration.

Once the passenger knows (knows and not measures) that his compartment
in the second frame has different velocity, he simply has to find out
if the pulse of light returns back to the source or falls behind. This
is the only experiment he has to conduct.

I am not even assuming any result. Whatever might be the result, SR is
a looser.

You have put your argument on its head. Instead of starting from
bottom to top you have put the train of logic in a reverse gear.
