No one knows for sure if the universe is infinite, or if you get to the end will it be like Pacman and you come out the other side? Maybe you just reach a brick wall? This song is about watershed moments in physics.
Is it infinite?
I don't know
If you get to the end, where do you go?
Aristotle's model had the earth as a sphere
But he thought that the world stayed stationary year to year
Newton showed to the world gravity
But Einstein said relative time is how it has to be
Copernicus said that we all go around the sun
Alan Cohen said that, "This revolution's never done"
