The point is that the speed of sound is NOT constant!
by this I mean that different observers, travelling at different speeds relative to the air, will observe different speeds for sound.
The air defines the stationary observer as stationary with respect to the air.

There is no such stationary observer definition for light.
All observers, no matter how fast they are moving with respect to each other) will see the light as traveling at the same speed.
Indeed the whole concept of a stationary observer becomes invalid,
There is only the motion of the observer relative to the observed event.
(One could almost say that ALL observers are stationary with respect to light).

Note that perhaps a better definition for "c" than the "speed of light" might be
c = the maximum speed of propagation of information

Hi, thanks again for your opinion. well i meant the speed of sound is constant in air or whatever medium it travels in. and so also is speed of light constant in Vacuum.

I must admit that our discussion has come to the stage where it becomes more like "your believe against my believe. your idea against my idea, your word against mine", and at this point, it becomes very hard to progress. Only Experiment can save this day. and Yes, i am aware that many experiments in Physics have been claimed to verify and prove the accuracy of Special relativity.

You believe in Relative nature of Velocity because of the Velocity transformation of Galileo and Lorentzo. well, the reality is that i don't believe that Velocity is relative, I believe that if an object e.g a toy car is calibrated such that it will travel at a speed of 50m/s when set in motion, then to any other observer of a different frame, the speed of the toy car must be measured to be 50m/s. it doesnt matter what the observers perceive the velocity to be. the Maths of my article did not rely on any velocity addition for it to be created. also, the maths of my article showed that there is no need for velocity addition/subtraction.

I dont believe in that proposed speed limit by einstein. sooner or later, we would become technologically advanced enough to create or witness objects/matters that travel much more faster than speed of light. i think the limit we should be talking about should be about our current technological power. The future is Hope.

You believe that there is no stationary observer and every motion is relative but unfortunately, my article did not support that idea. My article showed that some frames are better in their measurements than the others.

Personally, i believe that any specie that can be Intelligent and wise enough to build a spaceship and fly out of the earth into space, should also be intelligent enough to differentiate whether he is moving or he is at rest. Humans are not stupid. and i regard such conclusions as an insult to the human intelligence and capacity. I think many conclusions of special relativity looks rather funny to me. but thats just my opinion anyway..

thank you once again.

My personal belief is that it is unlikely that so many physicists looking into this problem over so many years will ALL have got it totally wrong.
There can be an element of "follow the leader" and "don't rock the boat" in physics (as in all walks of life),
But I think that there are enough genuine efforts by "respected mavericks" in physics to avoid too much enshrining of the current dogma.
Certainly enough that any obvious errors in the theories of relativity will have been identified.

However I agree with you, if we all stick solely to our personal beliefs, there is no progress to be made.
(This applies to all walks of life, not just this thread).

Hello MBW, thanks for the comment. yes, i agree that it is unlikely that so many physicists looking into this problem over so many years will ALL have got it totally wrong but you and i know very well that the most criticised theory in recent history is the special relativity.

I think it is also very likely that this special relativity has a problem and that is why ever since the day of its creation, it has been going through lots of criticism, even when Einstein was alive.

This idea of of "follow the leader" and "don't rock the boat" in physics has created a great shield and protection for the special relativity and as a result, anyone who tries to say anything against relativity is immediately regarded as crackpot or enemy of the public. I think this modern physics has become more political than scientific.

I am not the only one who is not agreeing with special relativity. you might check google and read few things about many people who do not agree with the theory and their respective reasons.

I think i have no choice than to "follow the leader" but keep my opinion and idea alive and hope that someday, enough evidence and better experiment will come out and resolve every misunderstanding. Until then, i live in hope of the better future.

My pleasure having this discussion with you in the most respectful and civilised manner.
Thank you. and enjoy your evening.
Michael

Fortunately, Physics has a clear way to break out of "follow the leader" situations- experiments. There have been a number of experiments done that validate the basic ideas of both special and general relativity. Do you know of any experiments that contradict relativity?
