Darunia, know what the difference is? People back then had proof of concept for flight, birds.


Yes, birds can fly. That does not mean that man can. It is not inately obvious that anything a bird can do, man can. It would have been difficult to conceive of gas-powered turbines and engines and propellers in the 5th century.

If birds = proof of flight = man can fly,

then

Photons = proof of speed of light = man can go that fast

Or, at least, close to it. To claim that our knowledge of physics is definitive, and there is no more to be written about the speed of light is ignorant.


I need you guys to stick around me, tonight anyway... I fear that DJ may try and burn me as a witch if I speak anymore of human travel at or near the speed of light.
