You Are Not Where You Think You Are

Look around you. Where are you? Where is this place you are occupying? Somewhere in a room, maybe in a city on a continent on a planet orbiting a star in a galaxy among billions.

But… where is all of that? While this may feel like a daft question, it turns out that the concept of an absolute position is something humans made up.

In a nutshell, the universe is a big bag of space that has things in it.
