And you're right, that's what's holding galaxies together and shapes the large-scale structure of the universe, definitely interacts via gravity.

But via gravity is very, very weak, right?

So if there is dark matter out there and it only interacts gravity, there's basically no way we could discover if it's made of particles because a dark matter particle that interacts only via gravity, undetectable.

Gravity is way too weak, right?

um but if there's another force and this is the big hope that maybe there's some other force out there that lets normal matter interact with dark matter and we could see dark matter winds interacting with us somehow

Well, if aliens can sense that force, then maybe they could see dark matter natively, and to them, it's not a big mystery, right?

To them, they see the whole picture, and they went a very different path for their science, possibly.

Or even weirder, if they're made of dark matter, right?

If dark matter is some new kind of particle or new kinds of particles, and it has dark physics and dark chemistry, why couldn't it have dark biology, right?

You know, we're talking about 5% of the universe made of atoms has all this complexity in it.

Now the other 30% of, of, of the universe, why shouldn't it have complexity, right?

Why shouldn't it be made of many different kinds of things with complicated, uh, emergent phenomena?

Maybe it's boring, maybe it's simple, but maybe it's very complex and maybe there's life in there.

In which case aliens could be made of dark matter instead of normal matter.

And, and wow, what a different way to experience the universe.

So I love that theory.

I never considered it.

But it also makes me wonder, we may not have the biological capability to understand how to create the device or the mechanism to ever see it.

Because we don't... You can't find what you don't know what you're looking... You know what I mean?

You don't know what you're looking for.
