When you reach a fork in the road
Pick it up like Einstein thought in nineteen-oh-seven
At his business of therefore’s that

People in free fall do not feel their own weight
Equals floating in gravity-free space
So no work force of gravity in either state and

Resting in gravity feels like one G of acceleration
And the feel of both is the same so
Both must have the same cause and therefore

Big-like-Earth things curve space and time and
Gravity, where the curve is — there! — itself arises
And — there! — acceleration feels like resting and

Light-beams acceleration bends in spaceships also
Mass bends like sun-bent starlight lends a cosmic lens on
That! — what the same thing causes.
