Is entanglement a consequence of the singularity of the early universe?

Click For Summary
SUMMARY

The discussion centers on the misconception that quantum entanglement is a consequence of the singularity of the early universe. Participants clarify that entanglement is well understood and not related to early cosmological conditions. The concept of Bertlmann’s socks is introduced, highlighting that any theory linking entanglement to early conditions must adhere to Bell’s Theorem, which has been experimentally validated. The thread concludes by emphasizing that misunderstandings about entanglement should be addressed, while reiterating the importance of established quantum mechanics principles.

PREREQUISITES
  • Understanding of quantum entanglement
  • Familiarity with Bell’s Theorem
  • Knowledge of Bertlmann’s socks conjecture

TL;DR
A naive question/proposition about the early universe and information
Does it make sense to explain entanglement as a consequence of the ‘singularity' of the early universe?

If proto matter/energy was in some mathematically definable ’small’ space, perhaps information was likewise compressed, and entanglement is a consequence of this early cosmological locality condition?

No doubt I have misunderstood something essential. Thanks for your consideration :)

Quantum entanglement is well understood and has nothing to do with what you suggest.

This sounds like a Bertlmann’s socks (Google or search older threads here for more on what this means) conjecture - something perhaps very far back in the past history of the particles has caused them to have opposite properties. However, all such theories must predict that the correlations between measurements on the entangled particles must obey a particular inequality (this is Bell’s Theorem and even more worthy of a forum search) while quantum mechanics predicts that these inequalities will be violated in some experiments. The experiments have been done and violations of Bell’s inequality have been observed; thus we are confident in saying that no such theory can be correct.
(Actually there is one remaining loophole, called “superdeterminism “. Again, search is your friend - this time it will show that superdeterminism is a philosophical deadend).

As this thread is based on a misunderstanding of what needs to be explained with entanglement, it is closed. However, threads about what is understood about entanglement and how it works are welcome.
