Quantum Entanglement: Particle Connection Effects

Click For Summary

Discussion Overview

The discussion revolves around the nature of quantum entanglement, particularly focusing on the implications of one entangled particle falling into a black hole and the effects on its partner. Participants explore the concept of entanglement, the relationship between particles, and the potential loss or preservation of information in extreme conditions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question whether all particles are entangled or if only specific pairs are connected, leading to confusion about the transition from "all particles" to "2 particles."
  • One participant asserts that if one entangled particle falls into a black hole, nothing happens to its partner, suggesting that their entanglement does not imply a direct connection in such scenarios.
  • Another participant challenges this view by asking how entanglement operates if one particle's state does not affect the other when one is removed from observation.
  • A participant explains that entangled particles exhibit anti-correlated quantum spins, indicating that measurements on one will yield opposite results on the other, as long as they remain entangled.
  • There is a discussion about the implications of entanglement and information, with one participant suggesting that entangled particles possess information about each other that is not accessible to the rest of the universe until it leaks out.
  • Another participant references Hawking's perspective on information not being lost when objects fall into black holes, although uncertainty remains about how or when this information might be retrieved.
  • Some participants express differing views on the necessity of guessing the meaning of entanglement, with one asserting that the meaning is already known.

Areas of Agreement / Disagreement

Participants express differing opinions on the nature of entanglement and its implications, particularly regarding the effects of black holes on entangled particles. The discussion remains unresolved, with multiple competing views present.

Contextual Notes

Participants highlight the complexity of entanglement and its relationship to black holes, with limitations in understanding how information is preserved or lost in such extreme conditions. There are also unresolved questions about the definitions and implications of entanglement.

Who May Find This Useful

This discussion may be of interest to those exploring quantum mechanics, particularly concepts related to entanglement, black holes, and the philosophical implications of information in quantum systems.

Are all particles entangled or connected to another?
Lets say we have 2 particles that are entangled . one falls into a black hole what happens to its partner?

Nothing. Why should it?

Ok so what happens to one dousnt happen to the other?? In what way are they entangled?

How do you go from "all particles" to "2 particles"? Where is the train of thought in between these two?

Their quantum spins on any given axis are anti-coorelated. What you measure for spin on an axis will be measured to be opposite on the other "partner" on the same axis as long as they stay entangled. What happens on the other side of an event horizon is out of the range of observation. Nothing happens to it's orphaned partner.

Let's try to guess what it means to have two entangled particles.
It means that one particle have some information about other, and other about first. Rest of universe doesn't have these particular informations.
Before these informations leak out to rest of universe these particles are entangled. They are somehow acting in universe in special way (talking about quantum effects).
So what happens when someone checks information on first particle. It seems universe acts as it knows all.

About black hole, Hawking says that information is not lost when object gets crashed. But i don't know when its get out of black hole or if it is instanteous.

2 different questions. .

Uh ... why would we want to guess when we KNOW what it means?
