The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

Oh, for sure.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

It keeps me up at night.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

And we might have thrown out the one thing we needed, but we don't know.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

But that's always the case, because we always have to make decisions about what kind of thing to look for.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

I'll give you another example.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

When we analyze our data...

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

we're looking for particles that come out of the collision and we expect particles to move in a certain way because they have electromagnetic charge and they have a magnetic field and we can use our physics to say, okay, particles always move in this particular path, a helical path.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

And if you look at like pictures of collisions, you see particles whizzing out in these spirals, right?

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

So spirals are everywhere.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

And most of our software that looks for particles looks for spirals because we expect everything to move as a spiral.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

And is that what you're mostly analyzing is just the paths of the particles from the collision?

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

That's what it is?

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

Yeah, exactly.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

Because the thing we're looking for, like the Higgs boson or something else new, it only lasts very, very briefly, like 10 to the minus 23 seconds.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

So you never see it directly.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

You see what it turns into.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

So we see the spirals, we see the particles, and we say, okay, that looks like there was a Higgs boson there.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

But it's not like I can say, oh, here's the Higgs, or here's a handful of them, or I got a bunch of them in a box, right?

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

We can only say that they probably were there based on the path of these particles.

The Why Files: Operation Podcast
Basement: Daniel Whiteson | CERN, Dark Matter, and the Aliens Next Door

So figuring out the path of these particles is important, but we only tend to look for these spirals because...
