I said negligible mass, not massless
If a photon manages to avoid termination with an object until the end of the universe (which means it will collide with something and terminate) then from its perspective, it just existed in more points in space during its 0 lifetime.
any particle has mass, and it is affected by gravity, this is proven by black holes sucking up anything, including photons of light.
what would *really* be interesting is to imagine what a tachyon's (which travels faster than light) perspective is... we believe time slows down to infinity when at light speed..but then how or what do these Faster than light particles ride on? they move through spacetime, but unlike at-lightspeed photons, the tachyon has gone beyond that... so what do these particles 'time' at? do they go against time (like that experiment having message arriving before it was sent)?
if they do, then they actually would terminate before being sprung into existence, going from point B to point A, but from our reference, we can only detect them at their termination point as they collide with our instruments.
spooky stuff.
