Yeah, this is a hugely, huge active area of research.

People are simulating dust on supercomputers, trying to stick it together, figure out what happened.

But it's chaotic.

I mean, you've got trillions and trillions of particles of dust randomly moving around and...

So solving the equations to calculate their motion is one of the most challenging things ever.

Maybe AI will help a big part with that.

It's so big.

It's strange, yeah.

Yeah, I mean, our star is – I mean, those big stars, those are actually rare, right?

So those are the giant stars of the universe, and most stars are not that big.

What is the biggest one that we found?

Oh, I don't know the name, but yeah, I think you're talking about stars which are probably filling up to the orbit of Jupiter type size.

Yeah.

It's nuts.

Yeah.

And these things are barely stars at that point.

Like if you actually, if you could zoom in a spaceship and look at the surface, it would, the gravity would be so weak at that point, right?

Because the mass hasn't changed of the star.

In fact, if anything, it's lost mass.

So it's barely got enough gravity to hold that thing together.
