I'm not sure I remember what I said then, but I mean, we have no idea how weird dark matter is. I mean, it's based on everyone thinking they know what dark matter is. I mean, so weirder than it already is. I mean, it's not already anything. We don't know what it is. So there's no normalization here.
It definitely does in the universe. I mean, so for example, there's more dark matter in galaxies than there is between galaxies. So it clumps. I mean, so it's matter. So it's distributed like matter. It is matter.

It's understood pretty well. People do simulations. I mean, where people are always looking for things, including us as particle physics, is sort of at small scales. Are there deviations on small scales indicating other interactions or other processes? or interactions with baryons, that is to say, normal matter that we don't understand.

But on large scales, we have a pretty good understanding of dark matter distribution.

I'm smart enough to know I have no idea. And also it's not even clear what science means, right? Because there's the science that we do, which is particle physics. We try to find fundamental things and figure out what their effects are. There's science like biology where It's at a higher level. The kind of questions you ask are different. The kind of measurements are different.

The kind of science that's going to happen in the more numerical age, or even AI. What does it mean to answer a question? Does it mean that we can predict it? Does it mean that we can reproduce it? I think we're coming up against the definition of what we mean by science as human beings. So in terms of the science that we can do, I don't think we'll know it until we get there.

We're trying to solve hard problems and we've made progress. I mean, if you think of how much science has advanced in the last century or century and a half, it's incredible. I mean, we didn't even know the universe was expanding at the beginning of the 20th century. We didn't know about quantum mechanics at the beginning of the century. We didn't know about special relativity.

That's a lot in a relatively short time, depending on how you think of time. So I think it would be premature to say we know the limitations.
