My first thought was 'no shit' as well. There's a horrible heartbreaking anime about that.. Voices of a Distant Star.

other forces ... can transmit information at speeds >c

I sadly disagree. Even if we figure out a way to instantaneously transport ourselves across the universe, there will be some shitty clause in fine-print that says we can't go back, or it took 0 time for us but 1 billion years for everything else.

Check out this video by Anton Petrov:

That's just time travel with extra steps!

[–] xkforce@lemmy.world 11 points 1 year ago (1 children)

It literally is time travel.

[–] gravitas_deficiency@sh.itjust.works 3 points 1 year ago* (last edited 1 year ago)

We are all currently time-traveling at a ratio of (edit: roughly) 1:1

They're probably referring to quantum entanglement, which affects the entangled particles instantly.

[–] echodot@feddit.uk 7 points 1 year ago (1 children)

Yeah but you can't interfere with quantum entangled particles, if you do you break the entanglement. So it isn't usable as a method of communication.

[–] intensely_human@lemm.ee 1 points 1 year ago

It isn’t usable as a method of communication by any means we’re aware of.

Something I’ve not been asked to get through my head about QE: If observing the entangled particle destroys the entanglement, doesn’t that mean we’d need “containers” of entangled particles to send a bunch of information?

[–] luthis@lemmy.nz 3 points 1 year ago

You can't send information with entangled particles. You just learn the state of the other particle by inference when you observe the first particle.
