Dark matter stands outside that. It's not interacting through those forces. When we look at the world around us, we don't usually see the effects of dark matter because there's so much of it that we do, and it doesn't have those forces that we know about. But the standard model has worked spectacularly well. It's been tested to a high degree of precision. People are still testing it.

And one of the things we do as physicists is we actually want it to break down at some level. We're looking for the precision measurement or the energy or whatever it will take where the standard model is no longer available. working. Not that it's not working approximately, but we're looking for the deviations.

And those deviations are critical because they can tell us what underlies the standard model, which is what we really want to see next.

So we don't know yet, but we know the kinds of things you wouldn't want to look for. So one obvious place to look is at higher energy. We're looking at the Large Hadron Collider, but we'd love to go beyond that. Higher energies means shorter distances, and it means things that we just couldn't produce before. I mean, E equals MC squared.

So if you have a heavy particle and you don't have enough energy to make it, you'll never see it. So that's one place. The other place is precision measurements. The standard model has been tested exquisitely. So if it's been tested at 1%, you want to look at a tenth of a percent.

And there are some processes that we know shouldn't even happen at all in the standard model or happen at a very suppressed level. And those are other things that we look for. So all of those things could indicate there's something beyond what we know about, which of course would be very exciting.

Absolutely, and that's why we'd like to understand it better. We want to know, is it part of some bigger sector? Why are these particles, why do they have the masses they do? Why is the Higgs boson so light compared to the mass it could have had, which we might have even expected based on the principles of special relativity and quantum mechanics? So that's a really big question.
