The paper is much more conservative than the article about it. They're saying that the close relationship between the signal and the human-made second, plus the fact that most of these signals were observed at one particular telescope, suggests strongly that it's a local, human source. "Paper doesn't rule out aliens" isn't a particularly strong statement. I've read many papers that don't rule out aliens, dragons OR u…

Is always a good idea to not rule out aliens, just in case. Especially aliens with elaborate senses of humour. It might explain a lot.

This is very interesting paper that just came out last week. So they found fast radio bursts (FRB) to have DMs (Dispersion Measure) that are in perfect multiplication with integers to a constant. This was supposed to be bit more random and so these being in such order is very surprising and unlikely to be just coincidence. Only 11 FRBs are found so far which might also means source of signal is not all around. On the…

No, they're not -- read the paper. You'll see that the DMs are close to multiples of 187.5, but not exact. In fact some are quite far off (5%). I'm slightly dubious of the paper. I haven't calculated the probability myself, but is the 1/10000 chance calculated from assuming they are exactly 187.5 multiples (DMest), or from the actual results (which aren't exact multiples)? I'm hoping it's the latter.
