The problem is, the past isn’t there any more. You can’t go back to something that no longer exists.

Trump has been doing this for years. :^)

If that’s the case, how many science fiction stories are now fantasy stories?

[Tellurian]

Uhh, sure, yeah. You first.

One problem with time travel that I’ve never had explained: the earth is not where it was in space an hour ago, let alone many years ago. And we’re not just talking about where it is relative to the sun in its orbit, because the sun and its solar system is moving though space; as is the galaxy.

So to go back or forward in time, one would have to move through space as well, find where you wanted to be and make sure you don’t materialize inside a tree or a wall.

Ok, then do it!!!! Similar to finding all those species that evolved from the previous “specie. “ Find those too. Fanciful buffoonery, just another clown filling up space to keep the money flowing in.

OK, just in these first few lines I know this is nonsense. This guy doesn’t know his physics.

I think whenever you go in time, you must also plot _where_ you will be in that time. Because the earth will not be in the same place. If you go back in time a week, for example, you need to also go back to where the earth was a week ago.

I read a story once where the character went back in time and taught the Romans modern medicine or gave them modern medicine. Something like that. The outcome was the Earth became so overpopulated thousands of years later, that it was like a writhing ball of humans. The aghast time traveller went back to ancient Rome again but this time he left a rifle.
