Reply to comment by 0xLenk in What if time travel is impossible because of this? by [deleted]

yes, very valid point. My thinking was that earth most likely does not revolve at a constant 67,000mph, its always a little varying therefore it would be impossible to fully predict the earths point around the sun. that being said im probably 100% wrong on this lol its just a super interesting topic for me.

I don't necessarily think we need to predict it's location, if we are time traveling back in time, its location was already known as it has happened before. We need to learn how to track the earths location in space.

Also could be 100% wrong also, just my theory.
