These days you can see all kinds of theories
Expounding themselves into existence,
Trying to explain the mysteries of the universe
From the little pieces of evidence
They carry around in their pockets.

Every morning, you can see them walking around in circles.

There's the theory of gravity
Throwing things up into the air again,
Trying to find out why they come back down.

And the theory of relativity filling blackboards
With diagrams of complicated equations
That never seem to get anywhere,
Never seem to come to an end.

The theory of evolution
Evolves into something else
From fossils embedded in metamorphic rock,
Over millions of years,
Unobserved.

String theory tries to tie together
Distant points and unrelated times
Separated by vast expanses
With the loose ends of its strings.

The theory of chaos doesn't make any sense at all.
