And you just wouldn't expect something this large that has this much mass to not have stars in it.

So it's this cloud of neutral hydrogen.

just kind of never formed a galaxy.

And that's really interesting because it means that we're kind of looking at something that probably is what the very early embryonic stage of our galaxy was before anything really developed in the very early universe.

It was just a bunch of neutral hydrogen around

And then that eventually through gravity coalesced into stars and dah, dah, dah, dah, dah, you get galaxies.

But this is just hanging out in space.

And that's kind of weird.

No, our galaxy is 100,000 light years.

Well, the observable universe is about 92 or 93 billion light years in diameter.

All right, fine, okay.

The universe itself has been expanding.

It's pretty close.

Exactly.

No, it's pretty close, yeah.

100%.

That is totally fine.

I'll send you my exam that I give my first year undergrads and then you can you can give it a try.

Please don't.

You know, my husband did that.
