Why Knot (String Theory According to Wonka)

Theorists say the universe
is made of tiny strings
of energy which mimic
the music of angels' wings.

"Can particles wave and act like a string?"
asked little Mike Tee Vee.
"Why not?" Willy Wonka replied.
"Since there's quantum gravity."

Newton was on to something
with his natural philosophy.
Einstein added so much more
with his theory of relativity.

"Can it really work?"asked Mike excitedly.
"Why not?" Willy asked again,
"Or why knot, more precisely?"

Why not 'Why knot'?
The universe is made of strings.
Why not 'Why knot'
with loops and waves and things?
