One of humankinds greatest intellectual advantages has been the ability to embrace contradiction to understand that something can be both itself and its opposite at the same time.

That comes in handy when talking about quantum physics. The subject ricochets between illustrations like Schrodingers cats (both alive and dead), and the infamously confusing Heisenberg Uncertainty Principle, which states you cant simultaneously measure the location and movement of a subatomic particle.

If you look at the image above, youll see what looks like a night sky filled with exploding fireworks. In reality, its a subatomic image of the constant creation and destruction of matter and antimatter.

Electrons and antimatter electrons, quarks and antimatter quarks they are created from nothing and disappear back into nothingness, Fermilabs Dr. Don Lincoln explains in the video below. Empty space is actually extremely busy.

These are called virtual particles, which Lincoln likens to the appearing and disappearing bubbles on a foamy root beer. (Regular beer is probably too controversial an example.)

But theres another name for this phenomenon as well: quantum foam.

Thats basically an attempt to offer a memorable image for a much trickier physics concept. Namely, that nothing is still something.

Intrigued?

Watch the full video above from the excellent YouTube channel Fermilab to get a firmer grasp on why empty space might not be empty at all.
