He was dead when we found out, how the fuck would he come back in time?

[–] Shrubbery@piefed.social 66 points 1 month ago (4 children)

Being able to time travel implies he could also jump forward in time (e.g. to check his posthumous reputation).

[–] Elgenzay@lemmy.ml 31 points 1 month ago (1 children)

But why does Stephen Hawking not being able to time travel mean time travel doesn't exist?

[–] corvi@piefed.social 39 points 1 month ago (2 children)

Probably a reference to his “time travelers party”, a tongue-in-cheek way he used to suggest backwards time travel is impossible

[–] agamemnonymous@sh.itjust.works 22 points 1 month ago (1 children)

Maybe no one came to his party because they knew he was on the list

[–] RestrictedAccount@lemmy.world 7 points 1 month ago

Or maybe the time travelers went back and faked his name onto the list as a prank.

[–] Elgenzay@lemmy.ml 3 points 1 month ago (2 children)

Ah right, so they would have given him the technology to do so i guess is what it's implying

[–] UnspecificGravity@piefed.social 5 points 1 month ago

Why would they do that, they know he's on the list.

[–] gnarles_snarkley@beehaw.org 2 points 1 month ago

He would have crushed the time traveler into goo and stolen the technology

[–] TachyonTele@piefed.social 21 points 1 month ago

Going forward is sadly the only way we can time travel. I explained this to Stephen in a couple weeks.

Yeah...a time traveller would be able to jump ~~forward~~ less backward in time to check that.

But Stephen Hawking wasn't a time traveller, he just wanted time travellers to visit him.

I want to jump over this time period to get a better time in future.

Well, all you need to do is travel at a significant fraction of the speed of light. That will let you fast-forward the rest of non-relativistic reality. Then it's just a matter of slowing down again.

Sounds very simple, thank you for that information.
