Sure. But assuming time is traveling the same for you, their origin point, and the photons going between the two, they won't suddenly appear when the event has just begun, even if they travel instantaneously. Because, as you say, the point at which they first saw the event had yet to receive the light image of the event.
And if they do seem to suddenly appear much faster than you would believe possible, you suddenly know that you're at the bottom of a time-dilation gravity well (or the equivalent). Though you probably could have figured this out beforehand from the red-shift of the light traveling between the two points. Or you know that they observed the event from a closer point of view, instantaneously traveled to a most distant location to change clothes, and then traveled again to your location. Time travel is only one of at least three possibilities.
- xwdv 4y agoIf you are in a time dilation gravity well, the mere act of outsiders traveling into it might be time travel itself, as they are traversing the well from the outside (what you would think of as the future) to reach a point inside where time is lagging behind.
- anonymouskimmer 4y agoTime may be lagging behind, but you aren't traveling backward in it. Merely transitioning to a slower tick-tock cycle.
- xwdv 4y agoSo in that case traveling into the heart of the well would feel like you are fast forwarding the events of the well until you gradually synchronize with the tick cycle and things move at normal speeds? In which case you could never reach the exact moment of the event you set out to see.
