This world we live in, per latest 'best-guesses' of cosmologists, consists of three distinct parts:- 4% is composed of the entire visible universe (all of humanity, all the stars, planets, solar systems, galaxies in the sky; then 23% 'dark matter', and 73% 'dark energy'. Dark matter keeps the galaxies from dispersing into discrete stars or systems, while dark energy is supposed to be the reason why all galaxies, star clusters, etc. are speeding away at an accelerating expansion rate from each other, instead of slowing down despite the millenium time lapse after the Big Bang. Actually, we cannot even pretend to fully know all of that 4% that is supposed to be visible or perceivable by humans. We could not even see our Planet Earth half a parsec away from our Sun. I think it was Thomas Edison who said "We don't know a millionth of 1% of anything." Every day we learn, and we may think we know a lot. In truth, we probably know less than a billionth of 1% of anything.
