Shouldn't we see more quantum entangled pairs?

[One Above All]

Given that all matter and energy in the universe was condensed into one point, shouldn't almost all matter be quantum entangled? Or does it have a "time limit" before the effect disappears?

I don't know enough about either one of them, but my best guess from what little I know is that if they're not entangled, then that might be because the singularity didn't have the same characteristics as photons and atoms and stuff that allows them to be entangled in the first place and I think it it can only happen in some certain kind of situation too. Either that or they can become untangled if they did entangle in the first place.


EDIT: Also, I thought the Big Bang came from some singularity thing that was as dense as all the matter and energy in the universe (maybe more) and eventually became a bunch of different particles later on, so it didn't even have anything to entangle with. Sorry if my ignorance is showing, but it's still fun and interesting to talk about and I might learn something here.

You make good points, Sleeping Shadow. I hadn't considered those. My main idea was that energy and matter was condensed into a point made entirely of energy, so particles couldn't become entangled because there were no particles in the first place.

I'm wondering it you are not only right but that matter is actually locked up energy too. We heard about the HIggs recently and the suggestion is that the Higgs is part of a Higgs energy field rather than an individual particle. Indeed, even the famous E = MC² would seem to suggest that everything is energy and not anything actually solid.

I don't know much about entanglement to really comment but maybe it makes sense if we see it as linked energy fields rather than particles. Time will tell.
