I wonder how you'd solve for time machine door position issues. You'd probably want the machine to be able to fly and be sure to arrive in earth's atmosphere.

I would stick with the true and tried: https://m.stacker.news/48504
as far as positioning, you got me thinking, wouldn't it work like coordinates? like the machine stays still but time and space move around it.
reply
That's what I'd imagine too, but coordinates in space relative to what? Earth isn't where it was relative to the sun when I began typing this, our sun isn't where it was relative to the center of the galaxy when I began typing this, and so on.

Exactly. You have to move backwards through time AND space. It's the theme of the movie TENET.
Another time-travel movie that accounts for this is the indie movie Primer, obviously vast differences in budget.

adding tenet to the list. I love a good time travel/parallel universe movie/show.

relative to itself. it becomes the event observer. since this is all hypothetical, and not to get lost in the sauce, I think it would be more fun to re-imagine it within the context of the timechain.
We can build models that can track + predict movement. like watch gears, each layer adds on another complexity. eventually covering the movements of everything. this could provide two things:
  • give us a reference for positioning: of ourselves, in reference to our planet, in reference to our solar system, in reference to our galaxy, and so on - in time.
  • give us a reference for time: like you said, we can not trust using the sun and our relations to it as a reference of time/space. there is no aug 28 2024 in space, and if history did not play out the way it did, we could be using another calendar with other dates. But we can use the reference for positioning to extrapolate a reference for time. since the the universe is expanding all the time, it should keep positions unique enough for no overlaps in time.
i give you the timespacechain.
