May the force be with you

Force equals mass times acceleration
if the Big Bang started this creation
there was first a supernatural cause,
or just random phenomenon of laws
that set the known universe in motion,
without purpose or the slightest notion
of what would initially be called space
so carefully mapped by the human race.
Everything tends to grow farther apart.
Our knowledge and formulas of force
does expand and accelerate of course.
Nary a planet or star can be steered
only our destiny can be veered
by neurons firing as if they're controlled
by free will that the stars cannot withhold .
