What happens if you take two quantum entangled particle and

Discussion Overview

The discussion revolves around the implications of sending one of two quantum entangled particles into a black hole, exploring the effects on the remaining particle and the nature of quantum entanglement in extreme gravitational conditions. The scope includes theoretical considerations and conceptual challenges related to quantum mechanics (QM) and general relativity (GR).

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that if one entangled particle is sent into a black hole, the other particle may also "disappear," while others argue that it does not necessarily follow that the second particle would be affected.
  • There is a discussion about whether observing the remaining particle would yield any unusual results, with some expressing uncertainty about the implications of such an observation.
  • One participant notes that while there is no experimental evidence for the behavior of entangled particles in black holes, the theoretical framework suggests that current rules of QM and GR should still apply.
  • Another participant raises the question of what happens to the wave packet as it crosses the event horizon of the black hole, indicating a lack of clarity on this point.
  • The black hole information paradox is mentioned as a relevant consideration in the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the effects of sending an entangled particle into a black hole, with no consensus reached on the implications for the remaining particle or the nature of entanglement under such conditions. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants acknowledge limitations in current understanding, particularly regarding the lack of experimental evidence for the behavior of entangled particles in extreme gravitational fields and the complexities surrounding the black hole information paradox.

...sent one into a black hole?
 
Physics news on Phys.org
You don't see it any more.
 
So the particle that didn't go into the black hole also disappears? ∞

No. Why would it?

No. But it does have one hell of a case of separation anxiety.
 
So when you observe the particle that didn't go into the black hole nothing odd will happen. I guess I'm asking an impossible questions since its going to be a long time before we can start sending stuff into black holes :)

No, we already know what will happen. It doesn't matter that we haven't been to a black hole yet, the rules still work the same.

Well, in theory, as we don't have any experimental evidence specifically for throwing entangled particles into black holes, the actual laws unifying QM and GR (if they do exist) could have a small correction causing the other entangled particle to instantaneously turn into a television playing 2001: A Space Odyssey. But, I agree, we have no reason to think our current rules break down when throwing entangled particles into black holes. Assuming that was your point.
 
There is no reason to believe that nonlocality, if it exists, can be affected by mass and gravity. AFAIK, no experiment so far has shown any such hint. The more interesting question is what happens to the wave packet as it enters the horizon.

Thank you Maui you probably asked the question I should of asked. I'm a Very, Very amateur physics guy and really enjoy watching shows on Nova and Discovery about physics and astronomy. My limited understanding of Black Holes is nothing gets back out once its goes past the horizon, so as you said what does happen to the "wave packet" as it enters the horizon.

The black hole information paradox comes to mind.
