But from the point of view of someone on... A spaceship traveling at the speed of light, which is an impossibility, incidentally.

Photons can travel at the speed of light because they have no mass.

So if there were a photon, it would take no time.

So from the point of view of a photon, time and space don't exist.

Yeah, if we get faster than light travel, perhaps. Right, right. That's the case. But, you know, there's the twin paradox. You could have two twins, and one travels at the speed of light some distance, comes back, isn't any older. The other twin could be decades older.

Would be nice, yeah.

There have been seminars on it held at the University of California at San Diego on what they call retrocausality.
