The physics of the relativistic counter-streaming instability that drives mass inflation inside black holes

Understand

If you fall into a real astronomical black hole (choosing a supermassive black hole, to make sure that the tidal forces don't get you first), then you will probably meet your fate not at a central singularity, but rather in the exponentially growing, relativistic counter-streaming instability at the inner horizon first pointed out by Poisson & Israel (1990), who called it mass inflation.

• The chief purpose of this paper is to present a clear exposition of the physical cause and consequence of inflation in spherical, charged black holes.
• Inflation acts like a particle accelerator in that it accelerates cold ingoing and outgoing streams through each other to prodigiously high energies.
• Inflation feeds on itself: the acceleration is powered by the gravity produced by the streaming energy.
