You said: “what if all the atoms in the universe gain the density of a black hole?”

Let’s unpack what that really means.

==== A black hole isn’t just “very dense stuff” — it’s matter crushed so much that: ====
* It sits inside its own Schwarzschild radius (event horizon).
* Gravity is so strong that not even light can escape.

So if you say:

: 

you’re basically saying:

: 

That means each atom becomes a black hole.

==== The universe has around ~10⁸⁰ atoms (roughly). ====

If every one of those:
* Collapsed into its own mini black hole,
* You’d get 10⁸⁰ tiny black holes instead of atoms.

What happens then?
* No more atoms → no chemistry
* No chemistry → no molecules, no stars, no planets, no life
* Just an ocean of tiny black holes.

But they wouldn’t stay separate for long…

==== Black holes attract each other. ====

With that many tiny black holes packed into the universe:
* They’d start orbiting, colliding, and merging.
* Small black holes → bigger black holes → even bigger ones.
* Over time, you’d get: - Fewer and fewer black holes - Each one more massive

Eventually, you might end up with:

: 

==== From the “inside”: ====
* No light from stars – because there are no stars.
* No atoms or normal matter.
* Just: - Black holes, - Gravity, - Some radiation (like Hawking radiation), - Maybe a bit of leftover junk falling into them.

From the “outside” (if that even makes sense):
* The universe is essentially just a black hole zoo.
* If everything ends up in one enormous black hole: - The whole universe is inside that horizon. - There is no “outside view” in any practical sense.

==== It’s more like a Big Crunch / Black Hole endgame than the Big Bang: ====
* Big Bang: super dense hot state that expands.
* Your scenario: everything crushed to black-hole density → tends toward collapse, not expansion.

It’s kind of like:

: 

==== If all atoms in the universe suddenly gained the density of a black hole: ====
* Each atom → its own tiny black hole.
* No more atoms → no stars, planets, or life.
* Gravity makes those black holes merge into bigger and bigger ones.
* The universe turns into: - A dark, black-hole-dominated place, - Possibly ending as one gigantic black hole with everything trapped inside.

If you want to go even further, we can try:
* What if just ONE atom in your body became a black hole? (that one’s surprisingly nasty too).
