Hi there,

If the big bang was originated from a singularity point, then how does the universe got created the way it is today?

Why doesn't the particles just blast away into a very dilute universe?

I think, the singularity point in the big bang wasn't that regular. What does explain the irregularity of the singularity itself at that point of time.

tq

The big answer is gravity (and time)  this is the thing that is pulling everything back together again very slowly.
Learn, create, test and tell
evolution rules in all things
God says so!

Yup, pulling back does happened.

But it doesn't explain the irregularity of our universe today.

What was the initial irregularities inside the singularity of the big bang that created the irregularity in the universe? It's kinda like Chaos Theory or Butterfly Effect, where small inconsistencies created huge outcomes inside a system.

Otherwise, everything will be the same, all looked the same inside this huge ball of matter that we called our universe.

"But it doesn't explain the irregularity of our universe today."
True, but quantum mechanical variations in the density of matter /energy in the very early universe meant that, very shortly after it formed, the universe wasn't totally homogeneous. Gravity will amplify those changes over time. That's enough to explain our observation of a lumpy universe.
Please disregard all previous signatures.

I've heard somewhere saying that quantum mechanics haven't exist yet in the first stage of the big bang.
