Nice theory! +rep
It technically isn't time travel, more like viewing the past since you can't actually interact with things and live there. But it would require one of two things:
- We create a way of traveling faster than the speed of light, and the further into the past you want to go, the faster you would have to travel. For instance, if you want to travel 1000 years into the past, you would have to go a thousand times faster than you would if you wanted to travel 1 year into the past, in order to get there in the same amount of time. The speed required to do this is hard to even comprehend, so I don't think this method will work.
- The other possibility is we invent technology that allows us to teleport, through the use of worm holes. Sounds like something out of science fiction, but it would be much more practical and achievable than literally traveling faster than the speed of light.
We would also have to develop a telescope so powerful that it could see humans from light years away. For example, if you wanted to see into Jesus' time, it would have to be able to zoom in 2000 light years, or 1,173,139,200,000,000 miles. (That's over one quadrillion if you were curious.)
Who knows, maybe one day it could be reality.
