Fast Radio Bursts and White Hole Signals
  We estimate the size of a primordial black hole exploding today via a white
hole transition, and the power in the resulting explosion, using a simple
model. We point out that Fast Radio Bursts, strong signals with millisecond
duration, probably extragalactic and having unknown source, have wavelength not
far from the expected size of the exploding hole. We also discuss the possible
higher energy components of the signal.
