The numbers describing the universe are so large they stop meaning anything, so scale them down. If the 13.8-billion-year history of the universe were compressed into a single calendar year, the Big Bang is January 1st, our solar system doesn't form until early September, the first life appears in late September, dinosaurs go extinct on December 30th — and all of recorded human history, every empire and invention, fits into the last few seconds before midnight on December 31st.
Space is just as staggering. Light — the fastest thing there is — takes about 8 minutes to reach us from the sun, over 4 years from the next nearest star, and 100,000 years just to cross our own galaxy, one of roughly two trillion galaxies. Understanding these scales is less about memorizing numbers than about calibrating your sense of where humanity actually sits: recent, small, and local.
