One thing turns into another thing.

This is the story of continuous change

Nothing remains the same. 

The sum Is always greater than the

constituent parts.

Yet a metamorphosis of hearts

Occurs when we know that

Differential calculus

Plots the rates

At which things change.

However, the total always remains the same.

E = mc2. 

Energy equals mass 

Times the speed of light squared.

Energy and mass matter

Because nothing remains the same.

Does it matter that dark matter 

Makes up  85% of the universe? 

Galaxies would tear themselves apart

Without the gravitational pull of invisible dark matter.

Visible matter makes up all of the stars and all of the galaxies

Yet only accounts for 5% of the content of the universe! 

PLUS ÇA CHANGE, PLUS C'EST LA MÊME CHOSE
