Document Summary
Situations such as the center of a black hole, the universe at the instant of the big bang. Two theories are incompatible at very small distances (e. g. 10- 35 m: quantum jitter introduced by the uncertainty principle is so big that space- time uctuates violently, every particle exerts a gravitational pull on other particles, when particles overlap then the de nition of gravity breaks down. Vibration of a musical string gives a distinct note, di erent vibrations = di erent particles. These strings may be vibrating in 10 space-time dimensions (6 extra dimensions of space, 1 dimension of time) Particle physics interactions can occur at zero distance, but. Einstein"s theory of gravity makes no sense at zero distance. String interactions don"t occur at one point, but are spread out in a way that leads to more sensible quantum behavior iau working.
