We all wonder that. What's even the measure of how far away we are? I mean, one way you can measure it is just by our everyday lives. In terms of our everyday lives, we've measured everything. In terms of what underlies it, there's a lot more to see. And so part of it has to do with how far we think we can go.

I mean, it might be that the nature of reality changes so much that even these terms are different. Maybe the notion of distance itself might break down at some point.

So it's an interesting thing. And this is often a confusion that happens. So there's sort of the fundamental stuff underlying it, and then there's sort of the higher levels, what we'll call like an effective theory at some level. You know, so we're not always working. I mean, when I throw a ball, I don't tell you where every atom is. I tell you there's a ball.

And so there might be different layers of reality that are built on terms of the matter that we know about, in terms of the stuff we know about. And when I say we've measured everything, I say that with a grain of salt. I mean, I measure everything by the standard amount. So...

So there's lots of phenomena that we don't understand, but often there are complex phenomena that will be given in terms of the fundamental ingredients that we know about.

Usually when you have a crazy, sorry, okay, when you have a far out theory, the thing you do is you test all the possibilities within the constructs that exist. So you don't just jump to the most far out possibility. I mean, you can do that. But then to see if it's true, you either have to find evidence of it, or you have to show that it's not possible without that. And we're very far from that.

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.
