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

You obviously have never been married.

She remembers things from the past before I was born, about me.

In the end, we are all Time Travelers. Some get to travel a little further than others, but on average, we get to travel through about 80 years.

The time travel of science fiction is just that, fiction. And it always will be. Like alternate realities, fun to imagine and ponder, but still just fiction.

There is this thing called the "block universe" theory which suggests that all space-time is an eternal block. The past, present, and future exist at all times. We each are a space-time curve running through this block.

This suggests no free will, or a rather constrained free will that somehow is compatible with determinism, as the future is already set in stone.

In a block universe time travel either will be there or it won't. Some being outside the block would be able to see if there were space-time curves that went backward through time.

Oh it’s there alright just like the future.

Think of time as a continuous flowing stream with no beginning nor end.

Maybe time/space appears to move in a straight line because we live here and it’s the only reality we’ve experienced. Similar to defining gravity as being the same on the moon and sun as it is here...
