Everything in the universe is made of 17 elementary particles and four forces. Those particles are incredibly small. Barely even a dot. As far as anyone knows, they are point-like, exhibiting no finite and definitive size, shape, or volume. In fact, they emerge as points from a universe-wide electric field. So, the solid stuff of everyday life is just a collection of minute dots, arranged in patterns, and held together by invisible forces.

Reality, is literally made of nothing.
