... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...

Imagine that you are doing particle physics experiments. You fire a beam of sub-atomic particles of mass 4.0x10 -24 kg into your detector at a speed of 100 m/s. Most pass straight through undeflected, but one of them came out with its mass reduced to 3.0x10 -24 kg, its speed reduced to 80 m/s, and in a direction which was deflected by 2.4 degrees from its original path. You think that it must have ejected a particle of mass 1.0x10 -24 kg. ...
