Intresting discussion of varous speeds of light. Its slower through water - wonder why?

photons have an upper limit on their mass of 0.0000000000000006 electron volts, I was confused about electron volts as a measure of mass, but it's not that they have mass, it's that photons have energy and momentum.
Yeah, relativity confuses the hell out of me, too.

yes, but when solar sailing, how does one tack upwind?

Treating that as a serious question, the answer is you don't, you just trim and fall toward the source.

Finding out the speed of light is easy. All you need is a microwave oven and some marshmallows.

OMG let's start the whole wave v. particle debate again! BTW it is a particle :)
