Down

Everything goes Down.
Chicago is Down.
You will go Down.

Gravity

There is a common misconception that gravity pulls mass towards mass however this is a lie. Gravity was created in 1836 by a Monkey-36. Gravity is actually just a force that pulls everything towards Down. The moon is currently going Down. According to The Prophecy found in a dead Lobster's shell in 1967: "When the last Blue Lobsters die, the moon will start rapidly going Down until it crashes into earth." This phenomenon is known as "Moon going down, crashing into earth and killing everybody." Good Luck.

Up

Up is not real. Up was never real. Everything is Down.

Formula

$((\sin x + \cos x)^{2} + (\sin x - \cos x)^{2})^{(\sin x + \cos x)^{2} + (\sin x - \cos x)^{2}} + \det I_{n} = \sum_{ζ = 1}^{\infty} 5 \cdot 2^{- ζ}$

This formula is expressed in m/s as down is considered a constant force, not an acceleration. This formula was found in Joliet.
