... 1 kilometer, and its temperature is 10−8electron volts. It is far too cold to emit anythingbut very low energy photons and gravitons. As it radiates, its temperatureincreases, and at some ... described by a real field, it cannotcarry any quantum numbers, and the transition evidently violates baryonconservation. The proton could then decay into a positron and an electron-positron pair. ... argued by Banks, Peskin and Susskind, and ’t Hooft. Throughout thisperiod, a few theorists, including ’t Hooft and Susskind, have felt that thebasic principles of quantum mechanics and statistical...
