Discussion Overview

The discussion explores the potential role of quantum entanglement in addressing various cosmological problems traditionally associated with inflation, such as the cosmological constant, isotropy, flatness, magnetic monopole, and horizon problems. Participants consider whether entanglement could maintain statistical causality throughout the evolution of the universe, as opposed to inflation's proposed phase change and exponential expansion.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants propose that quantum entanglement might explain several cosmological issues instead of inflation, suggesting it maintains statistical causality throughout cosmic evolution.
  • Others express skepticism about the feasibility of entanglement addressing all these problems, questioning if it is too much to expect from this concept.
  • A participant mentions that entanglement provides a non-local, superluminal alternative to inflation, which could account for inflationary phenomena.
  • One participant highlights a fundamental aspect of entanglement, noting that local measurements on one part of an entangled system do not reveal differences compared to non-entangled particles, which raises questions about using entanglement to explain local properties across distant regions.
  • Another participant discusses the necessity of spatial separation of entangled particles for non-local effects and the implications of this for understanding the horizon problem.
  • Some contributions introduce ideas about inverse dimensions and their relationship with conventional phase space or spacetime, suggesting they might provide continuity to non-locality in the context of inflation anomalies.

Areas of Agreement / Disagreement

Participants express a range of views, with no clear consensus on whether quantum entanglement can adequately address the cosmological problems traditionally attributed to inflation. Some participants are open to the idea, while others remain skeptical or seek further clarification.

Contextual Notes

Limitations include the dependence on definitions of entanglement and the unresolved nature of how entanglement could interact with local measurements and spatial separations in the context of cosmological phenomena.

Might quantum entanglement explain the cosmological constant, isotropy, flatness, magnetic monopole and horizon problems? Instead of inflation introducing a phase change that caused an exponential expansion in the early universe, perhaps entanglement has maintained a statistical causality throughout the evolution of the cosmos.

The problem of 'the quantum', is that:http://www.joot.com/dave/writings/articles/entanglement/

is only just being realized, quantum entanglement:http://physicsweb.org/articles/news/8/6/18

has only recently gone through its early calibration phase experiments.

There may be tests in the near fututre, that will clarify what is 'real' and what is 'entangled' reality?

Maybe that's a bit too much to ask from it? :smile:

Loren Booda brings up an issue I am interested in, namely has quantum entanglement been taken into account when explaining the early universe?

My thoughts exactly. It would take a lot more exposition to get me there.
 
Entanglement provides a non-local, superluminal alternative to inflation over the course of the universe. Such effect is the basis for many of the aforementioned inflationary phenomena (cosmological constant, isotropy, flatness, magnetic monopole and horizon problems). Can you think of a comparable alternative property? (Aside: my website below in its first article introduces primally correlated, "inside-out" dimensions as one such possibility.)
 
I think a basic rule about entanglement is that if you do local measurements on one part of an entangled system, you shouldn't see anything different than you'd see if the particles you measured were not entangled--you only see signs of entanglement when you measure every single particle in the system. If this wasn't true, entanglement could be used for FTL communication. Based on this, the idea of explaining any properties of one local region of space in terms of entanglement with other distant regions wouldn't seem to make sense.

But to have a non-local collapse of the wavefunction with an instantaneous correlation you have to spatially sepparate the two components (particles) of the quantum system. This can be only done at speeds below the speed of light or with the expansion of space.
 
Can inverse dimensions, entangled since the big bang with those of conventional phase space or spacetime, provide a continuity to an otherwise non-locality that enables the anomalies associated with inflation?

I don't see how inflation solves the problem with the spatial distance between two ends of the universe. As I understand it, the horizon problem includes the "fact" that parts of the universe are out of each-others sphere of influence because they are separated by a distance that could not be achieved at the speed of light.

I see no reason to resurrect a nearly 3 year old thread.
