I'll start it off, why doesn't light travel faster or slower then 299 792 458 m/s ?
It does travel slower. That's the speed of light in a vacuum.
How much energy does a photon have?
If it has no mass does it mean by e = mc^2 it has no energy?
ing magnets, how do they work?
So, Uppi, does that mean that protons have no magnetic moment, but positrons (the anti-particle mate of electrons) do?
Or do all charged particles (protons & anti-protons, positrons & electrons) have magnetic moments?
And does that mean that neutrons don't have spin?? Or do neutrons have spin, but no magnetic moment?
The constant nature of speed of light is an observed fact established by the [wiki]MichelsonMorley experiment[/wiki].
Einstein's theories take that fact as a premise.
Nope. As to why? I'm not really sure that's a sensible question. That's just the way it is.Yes, I know this, but why is the speed of light what it is, and can it be faster or slower unobstructed in vacuum?
Nope. As to why? I'm not really sure that's a sensible question. That's just the way it is.
Forgive me if I am not satisfied with that answer.
