A.D. Doug, PhD and Loki in “Unfinished Business”

You time travel in a place that has no time, right?

Loki

Right.

That's not possible.

Loki

I know...

So you traveling to a place that doesn't exist anymore is equally impossible, and therefore, it's something you might be able to do!

Loki

Sure. Excellent. Y'know, makes total sense. Doesn't sound like science.

No. But it does sound like fiction!
