Why We Can’t Walk Through Walls
Shadowcat! She’s one of the X-Men, and she can walk through walls!
Unfortunately, however, Shadowcat can’t be real. This is because she violates a basic law of physics that says two things can’t share the same space.
But aren’t atoms mostly empty space? Couldn’t she just slip into that space? Unfortunately, no.
It’s true that atoms are mostly empty space. (If a helium atom were the size of the earth, the electrons would be out in earth’s atmosphere, and the protons and neutrons would be the size of a basketball at the core.) But atoms can’t overlap because only a limited amount of electrons can be in the same orbit.
