That's cool, yes. I'm sure that people actually engineering cars or trains
go though all that sort of stuff. I don't imagine the teacher would have
assigned the problem if we needed to calculate that sort of thing. :-)

They do have mass. They just don't have rest mass. Indeed, the color of the
photon tells you its mass. And, in theory, the photons are going in a
straight line, and it's only the spoon ^H^H^H^H^H space that's bent.
