Through mathematical equations it became obvious that the way we had previously thought of particles as "points" or "little balls" of energy was inaccurate. These tiny bits of matter actually behaved more like wiggling, vibrating
strings. Strings are so small that Brian Greene, a
physicist and proponent, explains that if a single atom were the size of our solar system, a string would only be the size of a tree. Yet strings make up all matter from the quantum level up.
