I had the scale of existence explained very well to me. The world is a very big place. Humans survive on 30% of the habitable planet they populate. Our planet is pretty big. And yet every day, we see something that can fit one million Earths inside it: the Sun. Even still, the Sun is just one of four hundred billion stars in the Milky Way galaxy. It gets worse. There are possibly a hundred billion galaxies detectable by our telescopes. Not quite small enough on the galactic scale? The universe is expanding at such an accelerating rate that the stars forming new galaxies may never have their light reach us. The collective Universe (all in all, all universes are considered part of the collective Universe, or “all of existence”) is befuddling at best.
