TL;DR Summary
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.

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

Is quantum entanglement directly related to the singularity of the early universe?

Quantum entanglement is a fundamental property of quantum mechanics where particles become interconnected such that the state of one immediately influences the state of the other, regardless of distance. While the singularity of the early universe represents a state of infinite density and temperature, it is not directly responsible for entanglement. However, the conditions of the early universe could have facilitated widespread entanglement among particles.

Did the Big Bang create entangled particles?

The Big Bang theory suggests that the universe began from a highly dense and hot state. In such extreme conditions, particles were likely created in pairs or groups, leading to entanglement. Thus, it's plausible that the Big Bang event itself could have resulted in the creation of many entangled particles.

How does the concept of entanglement fit into the timeline of the early universe?

In the early universe, shortly after the Big Bang, particles were in a highly energetic and interactive state. During this period, known as the quark-gluon plasma phase, particles frequently interacted and became entangled. As the universe expanded and cooled, these entangled states could have persisted, influencing the structure and behavior of matter as we observe it today.

Can we observe evidence of early-universe entanglement today?

Directly observing entanglement from the early universe is extremely challenging due to the vast time scales and distances involved. However, the influence of early-universe entanglement might be inferred indirectly through the study of cosmic microwave background radiation and large-scale structure formation, although this remains a subject of ongoing research.

Is entanglement necessary to explain the uniformity of the cosmic microwave background?

Entanglement is not necessarily required to explain the uniformity of the cosmic microwave background (CMB). The uniformity of the CMB is primarily explained by the theory of cosmic inflation, which posits a rapid expansion of the universe shortly after the Big Bang, smoothing out any initial irregularities. While entanglement might play a role in the quantum fluctuations during inflation, it is not the primary mechanism for CMB uniformity.
