The Universe's Time Machine
Suppose some time in the far future, we figure out how to travel great distances across space in a short period of time. We figure out how to move light years away from Earth in mere seconds, whether it be through interdimensional travel or otherwise. Our telescopes become strong enough that we can capture light from ground level activity of a planet or star light years away. Our virtual reality and hologram technology become sophisticated enough that we can take that light from galaxies far away and cast it around us to recreate and experience a scene.
At some point, a stargazer realizes he is so far from Earth that the Earth he sees in the sky is actually many years in the past. He begins to experiment with this, repositioning himself either farther or closer to the Earth by light years at a time to see the Earth either older or younger. It is entertaining at first, especially with telescopes being strong enough to see things on the surface like you...[More]
