comment Is it foolish to distinguish between covariant and contravariant vectors?
I think that number there should be $0.01$ and not $0.001$...

I'm sure I saw it in the vapor above it.

comment Is anti-matter matter going backwards in time?
Just a note: If Freymann's view (a single electron bouncing back and forth in time) is true, then we would have exactly the same amount of electrons and positrons... Don't we?

comment If tachyons existed, would we notice them?
You can create space-like separated events by putting the trigger in the past light cone of them. The simplest case is flashing a light in the room. The event where the two light rays reach two opposite walls and scatter from them is spacelike separated.

comment How can we prove that a photon is absorbed only once?
"generally have buttons that produce one photon" there are single photon sources, those are important in quantum computing and quantum encryptions. So I think we already have a source that can spit a photon when you press a button.

comment How can we show that the speed of light is really constant in all reference frames?
My friend's point is that if the source of light is on the Earth too, then of course the measured speed is $c$ relative to Earth. Can you cite an experiment where the source of light isn't Earth based?
