Entanglement may reveal more about black holes? ...Even micro ones!

Click For Summary

Discussion Overview

The discussion centers around the potential implications of quantum entanglement in the context of black holes, particularly whether entangled particles can communicate information across the event horizon and what that might reveal about black holes, including micro black holes created in particle accelerators.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant proposes that an entangled particle sent into a black hole could communicate information about its experiences to its entangled partner outside the black hole.
  • Another participant challenges the notion that a singularity is a "rip in spacetime," asserting that it is a mathematical concept rather than a physical one.
  • Concerns are raised about the validity of the assumption that entangled particles can communicate, with a participant stating that there is no communication in entangled pairs.
  • Some participants dispute the claim that micro black holes have been created in particle accelerators, asserting that this has not occurred.
  • A later reply emphasizes that the original question about entangled particles and black holes is valid, but notes that current understanding is limited due to the lack of a theory of quantum gravity and the inability to conduct relevant experiments.

Areas of Agreement / Disagreement

Participants express significant disagreement regarding the nature of singularities, the concept of communication in entangled pairs, and the existence of micro black holes. The discussion remains unresolved, with multiple competing views presented.

Contextual Notes

Limitations include unresolved assumptions about the nature of singularities, the definition of communication in quantum mechanics, and the status of micro black holes in experimental physics.

Could an entangled particle (or larger entangled object), sent into a black hole, reveal anything new about black holes, with the connected entangled partner outside the black hole? Can entanglement escape the singularity and communicate with its partner?

I've heard the singularity is a rip in spacetime. If the entangled constituent in the black hole goes through this rip, can it still communicate with its entangled partner? Could it communicate what it sees on the other "side"? Like a system of entangled constituents that can report back intelligently?

If it stops communicating with its partner, does that mean that it is on the other "side" and is cut off? Or maybe the incredible gravity and compacting, collapsed it to determine the state of its partner? But if it doesn't collapse its partner to a state, then that would imply that indeed it has gone on to the other "side"!

I know that there have been "micro black holes" created in particle accelerators. So maybe we don't have to send anything into deep space, in order to answer these questions!

Where? Sounds like a popularization trying to be clever. A singularity is a mathematical object, not a physical one.

There is no communication in entangled pairs. Where are you getting this?

There have not.

It will be hard to converse sensibly because many of the assumptions are not correct.

That's not correct.

No, there haven't.

This is a valid question, and could have been your entire OP, since pretty much everything else in the OP is based on invalid assumptions, as @Vanadium 50 has pointed out.

The answer to the question just quoted above is that we don't know, because we don't have a theory of quantum gravity and we have no prospect of running any experiments in this domain any time soon. So anything anyone says on this topic is speculation at this point.
