The Force With No Name

The floor is not holding you up. Not really. You are not resting on anything. You are being repelled — very, very gently — by a force that has no common name, because we never thought we'd need one. Here is what is actually happening: the electrons on the surface of your feet and the electrons on the surface of the floor carry the same charge. Same charges push apart. They have been pushing apart since the moment you stood up, and they will keep pushing until one of you moves. You are, right now, hovering a tiny fraction of a millimetre above every surface you have ever touched. You have never touched anything. Not the chair. Not the hand of anyone you love. What you felt was the push back. The resistance. The invisible wall that says: no further. This is not a metaphor. This is electromagnetism — one of the four fundamental forces holding the universe apart — and it is the only reason solid matter feels solid at all. Without it, you would fall straight through the floor, through the rock beneath it, through the iron heart of the Earth, and out the other side. The floor is not a platform. It is a standoff between two clouds of electrons that refuse to share the same space. You are floating. You have always been floating.
