That "loophole" appears to solve some of these problems of infinities, making the idea appealing to physicists. Nothing can get infinitely close to a loop of string, because it will always be slightly closer to one part than another. The theory posits that all particles, instead of being point-like, are actually little loops of string. Because you can get infinitely close to a point, the forces acting on it can become infinitely large, and scientists hate infinities.Īn idea called superstring theory could solve this issue. But point-like objects complicate the laws of physics. In experiments, teensy, tiny particles like quarks and electrons seem to act like single points of matter with no spatial distribution.
