You'd expect there to be phosphorus, but it to be bonded with oxygen or some other compounds.

If it's bonded to hydrogen, there's something weird going on.

Makes sense.

Well, right.

And where that cloud deck happens to be, that stable, thick cloud deck I was mentioning, is at a place where the temperatures are moderate and the pressure is moderate.

But you can legitimately call that surface pressure uninhabitable, even not just being sort of human-centric or Earth-centric because...

almost no complex chemistry can survive there, like no organic molecules, nothing that is bonded to anything else basically can survive there.

It's so hot, it just rips molecules apart.

So that seems, even if you're not being sort of Earth-centric, it seems like that kind of temperature would be very hard for anything to live in.

Oh, man, what do I fear most?

Well, I'll answer that in a roundabout way.

Here's something that gives me hope, which is that last year we launched the Europa Clipper mission.

Love it.

Yeah, and if you think about the timescale, it's going to get to the Jupiter system in the early 2030s.

It's on its way there.

It's been launched.

They can't stop it.

Well, amusingly, it's on its way back to Earth now for a flyby, but it's going to Jupiter.

Yes, exactly.

So so I think about that and I think, well, OK, by the early 2030s, we'll have a different administration.
