Unknown Milky Way Signal -- A Gravitational Wave, Cosmic String, or Primordial Black Hole?

  In 1993 Stephen Hawking proposed in Black Holes and Baby Universes that there might be “primordial black holes which were formed in the early universe that could be less than the size of the nucleus of an atom, yet their mass could be a billion tons, the mass of Mount Fuji. A black hole weighing a billion tons,” Hawking explained, “would have a radius of about 10-13 centimeter (the size of a neutron or a proton). It could be in orbit either around the sun or around the center of the galaxy, emitting hard gamma rays with an energy of about 100 million electron volts.”

A Strange Signal is Emitting from the Milky Way

These cosmic signals were first detected last spring by several telescopes. A new research paper indicates that it was repeated twice since that time. These highly intense emissions typically last just a fraction of a second and are known as fast radio bursts (FBRs). Fast radio bursts (FBRs) The first FRBs were detected in 2007. Most of them are so far away that no one can ascertain their origin. Over 100 of these events have been reported as of now, but very few of them have ever repeated themselves, and much less has ever done so in a predictable fashion. As one might imagine, they are challenging to study and observe, and they have eluded astronomers for ages. Researchers have also reported that radio flares were recently discovered, which have proven to be the closest FRBs ever identified. They believe these FRBs were emitted from a celestial body known as a magnetar.
