On nature’s laws of cause and effect: a poem

everything that happens,
happens according to natural laws
if you only knew the laws of nature,
you’d know everything.
(Perhaps not everything, just
all there is to know.)

You’d know the past:
you could trace the interwoven threads of cause and effect back, back, back
(if you were good at math, and had a fast computer)
all the way to the Big Bang.

You’d predict the future
and explain all of the present, but
everything is cause and effect
every cause of something must be an effect of something else.
Each explanation prompts again the question: why?

Why the Big Bang?
Maybe you know; perhaps
a simulation run by aliens,
or string theory,
or God,
or something weirder.

where did your aliens come from?
