    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.

      That’s just time travel with extra steps!

        It literally is time travel.

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

        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.

        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?

          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.
