Big Bang Singularity: What Prevents Universe from Becoming Black Hole?

[Wallace]

I thought that mechanism was a supercooled higg's field causing a negative pressure. Is this wrong, or do you mean what caused it to supercool?

I think that is just one of many proposed mechanisms. There is a long way to go before we have a coherent theory of inflation with all the details worked out.

Ohh alright, so what are some of the other bigs ones to look into? And how mainstream is the one I mentioned in comparison?

Not sure. Too be honest I haven't heard of that idea. Where did you hear it from?

There are too many theories of inflation, or some process that isn't inflation but solves the same problems, to list. Some extend the standard model of particle physics (which the Higgs idea you refer to would be an example of) while some suggest new mechanisms entirely. This is a very dynamic field, not completely unconstrained by data, but none the less with plenty of freedom for new ideas that have the same effects as other ideas but with a vastly different cause.
