the REAL mystery of the universe, the wonders of inanimate balls of gas of uncomprehendable size, that develop gravitational rhythms that interlock with each other, the dance of gravity that gathers the scattered atoms into dust, rocks, asteroids, planets, stars, the awesome power of fusion, the great epiphany of the supernova that scattered the carbon from which you are made, the mysterious collapse to a black hole so heavy that light can't escape, the weirdnesses of stretching and bending of time

Enough to keep ones mind boggled for a few centuries - even without considering life...

Zenna Henderson in one of her "people" stories had a phrase about science - something along the lines of a primitive person looks at a tree and sees a tree. A scientific person looks at a tree and see xylem, phloem, photosynthesis, materials transport, energy cycles, stress ratios, tissue compression etc.

the advanced person looks at a tree and see a tree - realizing it is the sum of everything the scientific person sees - but uniquely a tree.
