Why didn't the universe turn into a massive blackhole after the big bang

Pretty much title. Why didn't the universe turn into a massive blackhole a second (or anytime soon after) after the big bang happened with literally all the universe's mass in such a small area.

Because the force that fuel the expansion of the universe (whatever that is, we're still not sure), was stronger than gravity.

Does that mean there is a time when some parts of the universe had the density of a blackhole but they weren't one?

1) mass came later, around 1E-32s
2) inflation (a certain kind of scalar field) between 1E-36s and 1E-32s

So what you're telling me is if we had something energetic enough, we could blow up a black hole?

well the other anon is really saying that other factors prevented blackholes from forming in the hotter denser early universe; blackholes can always form if the conditions are right. The early universe being smaller effectively had more space per given volume of energy and matter. Entropy decided that unfolding space and expanding/exploding was better than folding in on itself (it probably was already folded).

The big bang was special, the universe that we see here on earth is big and expanding and stretched out, so the local effects of matter and energy are magnified, relatively.

The traditional big bang is only possible if the universe is finite.

If the universe is infinite then it was never compressed into a finite area. Everything exploded everywhere.

currently subject to research (see GUT theory).
One possibility is that the characteristic of mass (Higgs field) was different during the early phases of the Universe and developed slightly later.

>>13794441
Not necessarily.
Density requires mass (D=m/V). If the characteristic mass hadn't developed yet, one couldn't perceive density.

Side note: How this works out with energy density, I can't tell.

No big difference in density from one region of the universe to the other so there was no major center of gravity for everything to collapse into.

where does 'the traditional big bang' say that the universe was compressed into finite volume?

with Juan Maldacena's approach you could infer that the universe is what's happening at it's border, so it's kind of like a black hole

Thats probably the effect of the aggressive, heavy handed, soi tranny leftist faggot moderation on 4chan, they've done everything they can on this site to turn it into Reddit2.0, eventually they will be successful. The transformation of Reddit from a relatively open, unmoderated website to a Facebook style propaganda operation took a long time, they started boiling the frog on that site nearly a decade ago and it wasn't really until a couple years ago that it was completely overtaken.
4chan is moderated by the same group of compromised homosexual pedophiles that moderate Reddit, the same ones who worked for Ghislaine Maxwell when she was the lead moderator on Reddit.

Maybe not blow up but with strong gravity field we could rip it apart. Then we rip 2 smaller black holes in 2 even smaller, and so on...
