Discussion Overview

The discussion revolves around the relationship between the universe's origin and the phenomenon of particle entanglement. Participants explore whether particles that emerged from a singular early state of the universe could remain entangled and the implications of interactions on this entanglement.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant suggests that since all particles originated from a small, homogeneous state, they might inherently be entangled, questioning what prevents this entanglement from persisting.
  • Another participant counters that particles can become disentangled through interactions, emphasizing that entanglement pertains to specific statistical relationships between states.
  • A further reply indicates that interactions between entangled particles could break their entanglement, noting the necessity of preparing entangled particles for experimental purposes.
  • One participant acknowledges the counterpoint about disentanglement but questions whether interactions would only occur among already entangled particles.

Areas of Agreement / Disagreement

Participants express differing views on the persistence of entanglement and the effects of interactions, indicating that multiple competing perspectives remain without a consensus.

Contextual Notes

The discussion does not resolve the assumptions regarding the nature of entanglement and the conditions under which it may be broken or maintained.

I was doing some thinking about entanglement and other stuff and a weird thought came up. Since the whole universe, or at least the visible universe, was at one time contained in a very small and homogenous "soup" wouldn't it follow that all the resultant particles that came later would have to be entangled? And if they were what would stop them from still being so? Thanks and use as much metaphorical language and imagery as you want in your answers. Thanks again...

Well, I thought of that but the particles would only be interacting with particles they were already entangled with, wouldn't they? So yeah, I'll check the links. Thanks.
 
An interaction between entangled particles may break the entanglement between them.
Mostly it won't matter ... we can demonstrate that two particular particles in the laboratory are not entangled in a particular way we are interested in: this is why we need to deliberately prepare entangled particles for our experiments.
