Some new equation's hit me
Something is not the same
I'm through with playing by
The rules of Aristotle's game

Delay my spectrum testing
Delay the fluid notes I keep
It's time to trust my instincts
And theorize
A leap

It's time to try defining gravity
I think I'll try defining gravity
To know why things fall down

How can you think you understand
The planet equations of Kepler?

I'm through inventing limits
The ones that Leibniz stole

Armed with this rate of change
And three laws I already know

Too long I've been afraid of
Sharing my inverse square law
Well here it comes:
Principia Mathematica!
In which I try defining gravity
Masses define the foci in gravity
And they're what pull things down!

Isaac
Come with me
Think of what we could prove
Together

Limited!
Your theory is so limited!
Low energy limit of its geodesic twin
Newton
Space conveys attraction

With.. a Hilbert action!

All semi-Riemannian!
With space and time defining gravity
Me/you and Einstein refining gravity
There's no such thing as down

Well? Are you coming?

I can't. I'm already dead
Oh! Right. Okay..

I hope you're happy
Now that your proof exists

You too!
I hope it brings you bliss
And you never wind up manic
And deny quantum mechanics!

I hope you're happy in the end!
I hope you're happy my friend!

So will you dare to join me
Taking the quest to find
One all-involving theory
Every force preserved and all combined
And if I die in toil
At least I die in peace
The world around me
Traced with geometric means

The way that I'm unifying gravity
Kaluza-Klein unifying gravity
With all the forces that we've found
And nobody, not Bohr or Bose
No physicist that is or was
Is ever gonna bring me down!
I hope you're happy!

Look at this new physics! Clever!

Bring me down!

Thank you for the physics!
Now we know why things fall

Ohhh!

Down!
