Only time travel to the future is possible. For example I will time travel one hour into the future and it will take me one hour to get there

My Lemmy client says your comment is 1h old. Is it possible to learn this power?

It still takes you an hour, it just takes everyone else near infinitely longer.

Slowing down the metabolism seems the mistake realistic thing we might be able to do to something like time traveling.

I saw it on TV when I was 7 or 8. I had nightmares for months.

Even though a bit cringy because of the metaphysical stuff, I really liked that twist on the time travel trope.

And the bike is a space machine, but not a time machine. What we need is a spacetime machine.

If used correctly, the bike can move you forward in time. It takes approximately 60 minutes to move an hour into the future. But you can't return so think twice before you go into a horrible age.

you can easily return to the past

but a tree used to be there where you are and now you've impaled it

Well, if we follow that logic, then where you end up is the emptiness of space, even if you go back exactly one year.

People tend to forget that the Earth not only goes around the sun, but the whole system is moving, so Earth is not in the same place as it was a year ago, even if it is relative to the sun.

I think that brings up the question of how do we go about establishing an absolute position? If everything is moving, what isn't?

Everything being relative is a hell of a thing.

Presumably all time travel devices, spells, etc. compensate for that. If someone figured out how to travel to the past, calculating where the planet was at the time should be easy by comparison.

Even more specifically, if we are talking a temporal teleport, then this shouldn't be a surprise. Most mainstream fiction uses teleports for time travel, pop out of one time and into another without experiencing the time between. As opposed to the device Farnsworth made in The Late Philip J. Fry, where they actually just change speed through time instead of skipping through it. In the latter case, you shouldn't have to worry about this issue at all. But with a teleport, any teleportation device is simultaneously a temporal and spatial teleport, due to causality and the nature of spacetime. So any teleport would need spacetime coordinates, not just spatial or temporal coordinates.

is THAT what that was about?

I only ever watched the first half of the TV movie. Second half never really seemed to air, or it really failed to explain anything.

Yeah, they fly through some "portal" or whatever and end up in the previous day. Then langoliers show up to devour it. There's some other madness going on, too. You know, typical Stephen King shit.

It is a plot point in the sci-fi series Perry Rhodan, where they push the whole solar system 15 minutes into the future (iirc) to hide it from the rest of the universe.

No, sounds like the solar system just got pushed out of phase with the rest of their universe.

4

The solar system will probably fall apart with the sudden disappearance of gravity of other systems

1

For the "present" of the rest of the universe it is just empty space, the Solar System is in a bubble of spacetime completely disconnected from the rest and continuously shifted 15 minutes.

I'd like to return to about 12 hours ago so I can sleep
