If one gets rid of the friction caused by air it is much easier to go faster than the speed of sound? And your reasoning is, if you get rid of photons/light you will be able to travel faster than light. Well I’m not sure if
that is how it works. but i like that your thinking. you might try your questioning at this other forum. http://www.physicsforums.com/
Erm no, sound and light are very different types of waves. A sound wave
is carried BY air, a light wave IS a photon.
And the speed of sound limitations are engineering ones (i.e. designing something that minimises friction etc) whereas the speed of light limitations are fundamental physical laws.
It's actually impossible for anything to go faster than the speed of light (as far as current theories predict).
