The Black Hole Collider

The inflationary instability at the inner horizon acts like a particle accelerator. The acceleration is exponential: particles undergo equal numbers of collisions in equal decades of Lorentz factor.

Energies easily reach and surpass the energy of the Big Bang. What does Nature do with this extraordinary machine?

If the accretion rate is large enough, inflation gives way to collapse.


  Inflation is followed by BKL collapse
