I think that it is not possible to travel to our past, I think we would actually be traveling to the past of another timeline, maybe one we created when we went there but it will not be the same world. If you get my point.
That too. The system should not tolerate time travel to any point before time travel itself was invented.
I heard not too long ago that, well let me just say “experts” because I’m not clear on if it was scientists or what, anyway these experts think time travel may be possible, but only to the future.
I didn’t hear if they said they thought you could come back to the present.
