We're missing half of the story.

And there's history there.

There's lots of times in physics when we've had a similar situation and it's worked out, like antiparticles.

Oh, it turns out we're made of one kind of matter.

That's just half of a symmetric thing the universe can do.

The universe can also do this antimatter thing.

Whoa, that's crazy, right?

Or, oh, we have electrons.

There's another version of electrons called muons and another version called taus.

And that exists through every kind of fermion.

So...

It's not just like wild speculation to imagine the universe has these structures and these symmetries and these patterns for us to discover.

It was a good idea and it was worth exploring.

There was a lot of hype about it.

A lot of people like made overly strong bets about how we were going to discover it and we didn't find it.

It's just, it's not there.

We looked for it, you know, it's not there.

If it's there, then it's very, very massive.

You know, in order for us to not have seen it, these particles would have to be really, really heavy.

And that unfortunately breaks the beautiful part of supersymmetry.
