Thank you for this framing. I haven't thought about this particular corner before! Also, if it is the case that from the POV time is not passing at all, all time passes in no time, which would mean perceiving the entirety of time in one static juxtaposition, but... can information reach a thing traveling at light speed? Does it matter the angle of incidence? (Nothing can catch up, but information-carrying particles like other photons could intersect or approach head on... but with their own relative velocity capped...?) Time to fire up the Wikipedia...

Nothing can travel faster than light, so no, nothing can catch up to something traveling at the speed of light. Really though the physics says nothing can _attain_ the speed of light, so light (or some other photon) could still intercept something with mass traveling at 99.9999999% the speed of light. And that thing with mass will never reach 100% the speed of light. If you want to look deeper I suggest checking out the accelerating expansion rate of the universe, and what that means for information traveling throughout the universe over the next billions of years. Humanity is actually extremely lucky to have been born at a time when the universe was young enough to still be mostly visible. Civilizations that come about in the next 10s of billions of years might actually assume their galactic clusters are the only ones in existence (much like we thought initially until Hubble found another galaxy).
