[Intro: Computer Voice]

Ahh yeah

I'm about to drop some particle physics in da club

Da LHC is supa dupa fly

You know what I'm saying?

Check it


[Verse 1]

Twenty-seven kilometers of tunnel underground

Designed with mind to send protons around

A circle that crosses through Switzerland and France

Sixty nations contribute to scientific advance

Two beams of protons swing 'round, through the ring they ride

'Till in the hearts of the detectors they're made to collide

And all that energy packed in such a tiny bit of room

Becomes mass particles created from the vacuum

And then


[Chorus]

Ahh yeah

LHCb sees where the antimatter's gone

ALICE looks at collisions of lead ions

CMS and ATLAS are two of a kind:

They're looking for whatever new particles they can find

The LHC accelerates the protons and the lead

And the things that it discovers will rock you in the head


[Verse 2]

We see asteroids and planets, stars galore

We know a black hole resides at each galaxy's core

But even all that matter cannot explain what holds

All these stars together something else remains

This dark matter interacts only through gravity

And how do you catch a particle there's no way to see?

Take it back to conservation of energy

And the particles appear, clear as can be

You see particles flyin', in jets they spray

But you notice there ain't nothin' goin' the other way

You say, "My law has just been violated!

That don't make sense!

There's gotta be another particle to make this balance!"

And it might be dark matter, and for the first time

We catch a glimpse of what must fill most of the known 'Verse

Because...


[Chorus]

LHCb sees where

The antimatter's gone

ALICE looks at collisions

Of lead ions

CMS and ATLAS

Are two of a kind

They're looking for whatever

New particles they can find

Antimatter is sort of like matter's evil twin

Because except for charge and handedness of spin

They're the same for a particle and its anti-self

But you can't store

An anti-particle

On any shelf

Cuz when it meets its normal twin

They both annihilate

Matter turns to energy, and then, it dissipates

When matter is created from energy

Which is exactly what they'll do in the LHC

You get matter and antimatter in equal parts

And they try to take this back to when the universe starts:

The Big Bang

Back when all the matter exploded

But the amount of antimatter was somehow eroded!

Because when we look around we see that matter abounds

But the antimatter's nowhere to be found

That's why....

LHCb sees where the antimatter's gone

ALICE looks at collisions of lead ions

CMS and ATLAS are two of a kind

They're looking for whatever new particles they can find

The LHC accelerates the protons and the lead

And the things that it discovers will rock you in the head

The Higgs boson, that's the one that everybody talks about

And it's the one sure thing that this machine will sort out

If the Higgs exists they ought to see it right away

And if it doesn't, the scientists will finally say

"There is no Higgs!

We need new physics to account for why things have mass."

"Something in our Standard Model went awry!"

But the Higgs; I still haven't said just what it does

They suppose that particles have mass because

There is this Higgs field that extends through all space

And some particles slow down while other particles race

Straight through, like the photon

It has no mass but something heavy

Like the top quark

It's draggin' its ---(!)

And the Higgs is a boson that carries a force

And makes particles take orders from the field that is its source

They'll detect it...


[Chorus]

LHCb sees where

The antimatter's gone

ALICE looks at collisions

Of lead ions

They're lookin' for whatever

New particles they can find

Now some of you may think that gravity is strong

Cuz when you fall

Off your bicycle

It don't take long

Until you hit the earth

And you say, "Dang that hurt!"

But if you think the force

Is powerful

You're wrong

You see, gravity

It's weaker than weak!

And the reason why

Is something many

Scientists seek

They think about dimensions

We live in just three

But maybe there are others

That are too small to see

It's into these dimensions that gravity extends

Which makes it seem weaker here on our end

And these dimensions are rolled up, curled so tight

That they don't affect you in your day-to-day life

But if you were as tiny as a graviton

You could enter these dimensions and go wandering on

And they'd find you...


[Chorus]

LHCb sees where

The antimatter's gone

ALICE looks at collisions

Of lead ions

They're lookin' for whatever

New particles they can find

The LHC accelerates

The protons and the lead

And the things that it discovers

Will rock you in the head


[Outro: Robot Voice]

Ahh yeah

Our understanding of the universe is about to change
