I don't know. It says there that we don't know. So I'm going to go with that. I mean, I think just speed reading that. It says a class of galaxies that... So I suppose we're looking at a kind of galaxy. It seems we're looking at a kind of galaxy that we don't see today in the universe. Red and compact, visible only during about one billion years of cosmic history.

So that would be, as I said, because we don't really understand the formation of the galaxies and these supermassive black holes, that's interesting because what you're seeing in the data is a kind of almost proto-galaxy, I suppose, these little tiny galaxies. That's what it seems to suggest. That's the first time I've seen that.

But just so, yeah, I think what we're seeing is that we don't understand how structures formed in the universe. We have a reasonable idea, but we don't understand the detail. And the more things like that you find, the more information you have to build models of how stuff formed.

I mean, there are several sort of proposed observatories. And also, by the way, gravitational wave detectors. So we've got LIGO, which is on the ground. There are proposals to put one in space, which is called LISA. One of the proposals is called LISA, which is lasers between satellites. So you can have much bigger things.

And the reason that's interesting is because there'll be gravitational waves from the Big Bang, right? So, you know, as you mentioned, neutrinos, you've got neutrino observatories, which can observe neutrinos from the early universe. And you can see things. It's just like light in a way. But it gives you a different view. You mentioned earlier, it's a different way of looking at the universe.

So the neutrinos will have information. Gravitational waves will have detailed information about the Big Bang itself. But we can't detect them at the moment because we can't detect those really tiny little ripples in space and time.

And we want to know. It's like you said earlier. We're asking very deep questions about why the universe is the way it is. And maybe why there's a universe at all in the sense that did it have a beginning? Right. And if so, what does that mean? What does it mean for something like this to begin? Yeah, I really... I find it... And the most exciting thing of all is that we don't know.
