So if I was in a space battle and the enemy 'jumps to light speed'(1) to make a quick escape ... they would actually be easier to target with a laser because they 'slow down' from my perspective?
(1) 'light speed' as in the speed of light, not as in a sci-fi context of hyperspace jump/FTL jump.

Since the universe expands with >1c, I wonder if the photon actually crosses the whole universe. And if not, how it would look like from the prespective of the photon?
E.g., to a photon moving at 1c, the whole universe has a contracted length of 0 meters, and it crosses the whole universe instantly. To us, observers at <1c, the whole universe has a non-contracted length of <a lot> and the photon takes <a long time> to cross the whole universe. By the time the photon's 0-second journey across the entire universe has finished (whatever that means), we're all extremely old. :D This is the time dilation meme of slowly-aging space travelers but taken to the extreme.
