Can You Go the Speed of Light?
Einstein's classic thought experiment involves sitting on a train travelling at the speed of light. If you hold a mirror in front of your face, will you see your reflection in a mirror? How...

What would it look like to ride alongside a beam of light?This is a question Einstein had asked over a hundred years ago.Now the trouble was, he couldn't actually do the experimentso he had to use his imagination;he had to do a thought experimentto figure out what a reasonable outcome would be.I could imagine there'd be some element of nausea.I'd imagine everything would get more intense.Maybe it would confuse the brain; I don't really know if you'd be seeing very much.I was on a water slide just a couple of days ago and I found that really difficult.Einstein's intuition told him that the world should feel the same in all frames of reference moving with constant velocity.These are called inertial frames of reference.So it ...
