... If all photons have the same speed (the speed of light) and the same mass (zero), why does an individual gamma-ray photon have more energy than a radio-wave photon? ... The equation E=mc 2 states that mass ( m ) and energy ( E ) are manifestations of the same thing; mass can change into energy, and energy can change into mass. The speed of light ( c ) is the conversion factor between the two quantities. ... Get instant access to subscriber content on Astronomy.com! ...

... 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. ...
