I think we always have in our head maybe that we'd like to find that, but I have to, I mean, I might not seem so, but I think I'm kind of more humble than a lot of physicists. I'm not sure that we're ever going to get to that bottom level, but I do think we're going to keep penetrating different layers and get further.

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.
