Reply to comment by AussieWalk in Whats stopping us from sending a probe into a black hole if we haven't already? by stealth941

Nothing would happen.

You can read up on what Quantum Entanglement actually means in this thread.

Sadly, PopSci has completely misrepresented Quantum Entanglement, and it doesn't mean what most articles about the topic says it means.

So the entanglement would break because of how time passes differently close to a black hole?

The problem is that there is no way to communicate with entangled particles alone. Even if we assume perfect entanglement preserved all the way into the black hole, there's no way to send information: this is known as the no-communication theorem.

Wouldn't that be true of any mass? All mass has gravity thus would affect space-time?

Is it really determined how entanglement interacts with black holes? I’d thought that was kinda open. Like, according to the “no hair” theorem they ought to destroy information, but that’s not unitary, which is kinda essential to the behavior of anything entangled with them (and quantum physics in general).

There are proposed resolutions to this apparent paradox but is there a consensus on the right one? And if not, would an experiment near a black hole be useful to distinguish between theories?

Sorry, I shouldn't have implied there was no interesting science to be done with entangled particles and black holes, I meant to just say there is no way of using entangled particles to get information out of the event horizon of a black hole

Wait is the hologram a thing or isn't it?

The holographic principle is a thing. There are hypothetical descriptions of a black hole that say all of the information about the particles that entered the event horizon is spread out on a 2-D layer around the event horizon.

This math could be extrapolated to show that all of our reality is a projection onto the surface of a higher dimensional universe.

There is no proof for this. It is only a mathematical description of one of the ways our universe might look from some higher dimensional perspective. As far as I'm aware, it is based on sound science, but that doesn't mean it is true.

PBS Spacetime on YouTube did a whole series of videos on this.
