15. Quantum mechanics stimulates that if a reaction is possible the opposite is also possible

The best way to describe the theory is this IMHO. The event horizon can affect the production of matching pairs of particles and anti particles. Now imagine them stuck together like magnets. As the gravitational forces ripe them apart picture the negative particle turning and ejecting the positive free.

Other factors are at play like frame dragging so the black hole would actually be spinning.
