Everything around right now, the computer, desk, chair....they are made of atoms of different types. These atoms are infinitely small as I learned in engineering school, however the atoms themselves are largely empty space. Everything around you is made of teeny tiny things that themselves are almost entirely empty of matter. These colliders, CERN and such are finding yet tiny-et particles make up the empty space which is what little exists in the largely empty atoms. Crazy right and there is no reason to expect this all won’t get ever more confounding.
There was once a people that built a high tower to challenge the preeminence of God, God responded by confusing their language.
=> Science on the sub-atomic level or greater universe level is something we will never fully understand, because the solutions become ever more inexplicable -like a confused language.
That’s my theory of the universe from first principles.
“So nat’ralists observe, a flea
Has smaller fleas that on him prey;
And these have smaller fleas to bite ‘em.
And so proceeds Ad infinitum.”
