Investigating Fast Radio Bursts.

Interesting that Cornell Univ. is perusing this possibility that these burst might be other than naturally generated. Any result no doubt a long way out but major university department is trying to determine their origin.

"Fast Radios Bursts (FRBs) show large dispersion measures (DMs), suggesting an extragalactic location......
We speculate that this could originate from a Galaxy population of FRBs, with Milky Way DM contribution as model deviations, and an underlying generator process that produces FRBs with DMs in discrete steps. However, we find that FRBs tend to arrive at close to the full integer second, like man-made perytons. If this holds, FRBs would also be man-made. This can be verified, or refuted, with new FRBs to be detected."

Following up on perytons and FRBs.

Cosmic objects might, by some natural but unknown process, produce dispersions in regular steps. Small, dense remnant stars called pulsars are known to emit bursts of radio waves, though not in regular arrangements or with as much power as FRBs. But maybe superdense stars are mathematical oddities because of underlying physics we don't understand.

The answer may come in the measurement of these bursts and their pattern and frequency as to whether these are natural emissions of galaxies or of a non natural source.
