This is an I-Hart podcast.

Guaranteed human.

How can massless photons add to a black hole's might?

Can you really make a singularity out of light?

Organs that come in twos include the long, hand, kidney,

foot, and eye. But why do I only have one of some things? And what's the plural of anus?

Ain't I? Could drifting bubble universes collide to end our cosmic show? Might gravity in other dimensions ever let us know?

Whatever questions keep you up at night, Daniel and Kelly's answers will make it right.

Welcome to Daniel and Kelly's extraordinary universe.

We've done 28 of these.

Yeah. done 28 of these. Hello, I'm Kelly Weir-Smith. I study parasites and space and whatever it is that you all

ask me when you send us emails.

Hi, I'm Daniel. I'm a particle physicist, and I've answered a lot of questions from listeners,

but never any about ani.

Oh, no, Daniel, you'd be taking my questions. I am the A&I experts in this group. Thank you very much.

You stick to the black holes and I stick to the

biology black holes. Isn't there an obvious connection? Exactly. Aren't black holes a sort of

physics anis? Yeah. Yes. Yes. In I of the universe. All right. You stick to the an eye of the

cosmos. I stick to the an eye of the earth. But wait, now I'm

realizing it we have it all wrong, don't we? Black holes are more like mouths, and white holes would be more like anuses. Why? Because things don't come out of black holes. Oh, they go in, and things go out of white holes. Well, you know, yet another instance where the physicist did a poor job of naming things.

There you go again.

It is hard to keep the ins and the outstreet sometimes. Well, you know, yet another instance where the physicist did a poor job of naming things.
