Why Can’t You Walk Through Walls?

You simply can’t walk through walls. Because according to the Pauli Exclusion Principle, no two particles can exist in the same place – it’s just impossible for both the particles — within the limits set by the uncertainty principle — to have the same position and same velocity.

THIS IS COOL. I WANT TO LEARN SOMETHING ELSE, TOO!

  1. Its actuallyelectrostatic repulsion between the electrons in you and the electrons in the wall that stops you. Both you and the wall are nearly completely empty space and you need to get to the density of a neutron star before you run out of gaps for them to slide past each other. Better to think of a line of soldiers in parade, each waving a long bayonet. Lots of room for another line of soldiers to pass through, but those pointy bits will really get in the way!
