physics
waves phases and guided particles beyond the outer reaches of the galaxy the light fantastic riding through the universe on a quantum horse. how much does it matter in the end? scientists screaming 'i've got it!' to an accompaniment of a cacophony of disagreement and insults and the creationists calling on their gods to bring down hellfire on this sinful world. and wars burn on, aided by the scientists' accomplices, still killing millions but only now killing the millions we want, no one else (except for a few collaterals). and soon we will burn ourselves out, in a million years or a billion sanity will be restored to the earth by the utter destruction of our form of sentient life. and then? maybe another species, another thousand million years, another holocaust ad infinitum, until this universe's 20 billion or so remaining years run out and entropy sets in. the final 'the end'.
