Let's assume that somehow humanity invented a teleporting machine that could momentarily transport a person over very large distances (up to several light years).
As we know, the speed of light is finite, and so the light from all stars and planets gets to us for quite some time. As an example: Sun is about 8 light minutes from the Earth, so if the Sun explodes or whatever, the observers on Earth will know it only after 8 minutes.
So, the question: if a man from Earth teleports momentarily to some planet 1 light year away and looks on the Earth with some really powerful telescope - what will he see? Can he witness all the events (well, whatever can be caught with the telescope) on Earth for the past year prior to teleportation? Does it mean that moving faster than light is actually time-traveling to the past (from the travelers's POV)? And does it mean that because of this "time paradox" an object moving faster than light breaks the timeline and therefore it's impossible?
