" I was going back and reading Marconi’s last book again, and there’s this part that
always gets me. He points out that the amount of the universe a human can experience is
statistically, like, zero percent. You’ve got this huge universe, trillions of trillions of miles of empty
space between galaxies, and all a human can perceive is a little tunnel a few feet wide and a few feet
long in front of our eyes. So he says we don’t really live in the universe at all, we live inside our
brains. All we can see is like a blurry little pinhole in a blindfold, and the rest is filled in by our
imagination. So whatever we think of the world, whether you think the world is cruel or good or
cold or hot or wet or dry or big or small, that comes entirely from inside your head and nowhere
else. "
