Sci-fi might have spoiled us with how communication would work in space.

Subspace is the answer of course!

    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.
