in case anyone is interested Unruh radiation is somewhat like Hawking radiation, a quantum gravity thing----so I will post it here http://www.arxiv.org/abs/hep-th/0510089 Unruh Radiation in Atomic and Nuclear Systems Shahar Hod 2 pages "We analyze the Unruh radiation effect experienced by an accelerated particle in atomic and nuclear systems. For atomic systems, the effect is shown to be negligible as compared to the characteristic energy of the system. On the other hand, we find that a quark inside a nucleon may experience Unruh radiation whose energy is comparable with the quark's own mass. We discuss the implications of these results." Shahar Hod already provoked a disturbance with his conjecture about BH seminormal vibration modes and the relation to Hawking radiation. Always looking for excitement.
