Hi
I would just like to ask a few questions bugging me.
1. Why do we regard a photon as having no-rest mass. Is the fact that a photon is 'never' at rest enough of a reason.
2. Why don't we take the photon into consideration when dealing with the gamma factor.
3. Our most sensitive equipment use light. Let's make this huge assumption that we get an object to travel at a velocity much higher than the speed of light, how then can we ever measure any speed higher than c. I hope I make no offense by this but according to me there are some parts of special relativity I am against, here is one silly argument: If we were all moles blind but not deaf. Why wouldn't special relativity revolve around the speed of sound(through air)? How would we know of light? if we stood in front of a supersonic aircraft which would someway avoid colliding with us as it approaches us, what speed would we measure? Say the craft was moving at mach 5, I will make a safe bet that our most sensitive equipment would be based on sound waves. With no doubt the sound wave which we measure would arrive only at the speed of sound. This is the quite similar to the simple scenario used to explain the basics of special relativity.
4. Following from 3, what is so special about the photon?
Thanks
