Everyone is reacting with one another.

But early on, we think that there were these cycles coupled to one another.

So they produce the waste, that's a chemical, and another cycle takes it, rotates it, there's input and output constantly.

And that is really probably the most fundamental form of metabolism.

I mean, life is in a way, too.

But you can also simplify it in the basic form that we like to refer to them as autocatalytic.

So they've been able to catalyze their own presence.

You said it better than my...

Out of catalytic.

The first, well, it's amazing that you were in that room, first of all, that's pretty cool.

The second, though, is that we know now that the size is not necessarily a determinant of life forms.

Their base, the ribosome itself, the presence of a ribosome, I will argue, would be life, right?

So it has to come together through biology.

So size itself is not...

what I would go after if I were to first criticize that sort of finding.

So no, size alone isn't.

We know this.

And that's the beauty, I think, about space exploration is that we learn so much about what are the limits of life and what life is.

Is it something that I know when I see?

Or, you know, is it something that I can attribute to size?
