It took me a long time to figure out there was no “biggest” number, that there would always be a number that was 1 more. Ah, infinity (and beyond). Applying that to the size of the universe is a whole other mind-blowing thought process. If the universe is infinite, you can never stop going, you can never run out, you can never reach an end. Impossible to think about.
