So I guess what I'm thinking is they're imagining an expanding universe before they even knew anything about galaxies.

That's right.

They're just thinking about stars in the night sky as the universe.

So without galaxies, we have no knowledge of an origin of the universe, and we'd be dumb stupid.

Yeah, so yeah, we have to do astronomy now.

Yeah.

So, Jana, before we take a break and then get to our actual cosmic queries with people's questions, I lose sleep at night wondering whether we today live in a time where an entire chapter of data

has been removed from our awareness, just as it will be in the day when there are no galaxies.

In a post-apocalyptic civilization, they will know nothing of Chuck's stories about the day gone by, and they will try to figure out the universe with what they've got.

So what chapters are we missing today, thinking we have full access to all the data, yet we don't?

Wait, so Chuck, she's saying one day a new dimension is going to grow out the side of your body.

Believe me, since the pandemic, that has already happened.

Chuck has six legs and five feet.

We've got to take a quick break.

When we come back, Jana, you're here for us.

We're going to take questions from our Patreon members when StarTalk returns.

StarTalk Cosmic Queries.

This is a celebration of the release of the second StarTalk book called Cosmic Queries, inspired by this spinoff of our show.

One of our more popular formats of the StarTalk portfolio.

And Chuck, I got you here for this, of course.
