It has been made clear to me that any velocity can be seen as rest mass, meaning that if I observe someone else experiencing time more slowly than me due to general relativity, so long as they do not change velocities, they will see me as experiencing time more slowly than them. I have also heard that, from from our point of view, anything traveling at the speed of light (in other words, any mass-less particle) does experience time, or appears to be forever frozen in time. But this leads me to another question that, how would an object with mass appear to behave from the point of view of something traveling at the speed of light? And for that matter what would something traveling at the speed of light observe when observing another mass-less particle that is traveling in the exact opposite direction
