From the brains behind brains on, this is the Moment of Um.

Um, Um, Um, Um, Um, Um, Um, Um, Um, Um, Um.

Moment of Um comes to you from APM Studios. And this show is so hot right now. I should know, because I'm the sun.

Um.

Seriously, I'm not even trying to brag. I'm really not. It's just a fact. You can't even

look at me without toasting your eyeballs. Are you intimidated by my beauty? Is it blinding?

I didn't do anything to get this hot. I've been a perfect sphere

of gas and molten plasma for literally billions of years. I mean, it's not my fault that I'm

the hottest thing in the literal universe. What do you mean you're not sure about that? Ravi, what do you think?

My name is Ravi. I live in Washington, D.C. My question is, is the sun the hottest thing in the

universe? My name also means the sun in Sanskrit.

The sun is the hottest thing in our solar system, but it's not the hottest thing in the universe.

My name is Mark Poppinchuk.

I'm a graduate student at the CUNY Graduate Center and at the American Museum of Natural History.

It turns out the sun is kind of like a middle-sized star, and bigger stars are going to run even hotter than the sun. And that's not the hottest thing in the universe yet, because besides

stars, there are other things that get even hotter. If you think of a black hole, you think

there's no light coming from it, it's this black thing.

But around a black hole, there might be stuff that's falling onto it.

This kind of what we call an accrucian disc around a black hole.

And that can get even hotter still to almost 200,000 degrees Fahrenheit.

So these are really, really hot things.

And it can even get hotter still.
