I call this the Mandelbrot universe and the fractal universe because this is exactly what it is.

I would say that as much as I do believe to sending probes to explore the universe, I say we should also look inward.

to find the answer to some of the profound questions of who we are, what's life, what's the nature of life, because we are expressing life.

The nature of life, absolutely.

I am more interested in that because the day we understand the nature of life, then we have a universal biosignature.

And it doesn't matter whether this life responds to the same kind of biochemical processes as we do, although it makes sense.

I told you about the generational aspect.

of the bricks of life, the stuff we are made of.

The sun is part of the youngest generation of stars.

And the first two generations of stars didn't produce the kind of elements we are made of.

They were stars that were either without metal, just made of helium and hydrogen, or poor in metals.

So the stars died off and stars like the sun were born from those.

And this is why we have elements like carbon, hydrogen, oxygen, et cetera, now.

And that's the life we're built on.

So I think it's not stupid to be looking for something that looks like us, because right now in the universe, this is the stuff that's the most abundant.

And we see with the exoplanet, with Kepler, with TESS, and now with James Webb.

we see that there are many, many different types of planets that may be habitable in the habitable zone of their stars.

There are countless stars like the sun, but more interestingly enough, there are other types of stars where you do have habitable zone as well, and where the duration of the stars are sometimes a thousand times more than our sun.

So you can imagine all sorts of things.

And you can imagine what type of life would be around those stars.
