The universe is not just a collection of stars and galaxies; it's a complex web of interactions and phenomena that we are only beginning to understand.

Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues. The story of civilization is the story of what happened on the banks.
