Powerful Radio Signal From Deep Space Appears To Be Repeating On A 16-Day Cycle

Recommended Posts

One of the defining characteristics of the mysterious deep-space signals we call fast radio bursts is that they are unpredictable. They belch out across the cosmos without rhyme or reason, with no discernible pattern, making them incredibly hard to study.

Now, for the first time, astronomers have found a fast radio burst (FRB) that repeats on a regular cycle.

Every 16.35 days, the signal named FRB 180916.J0158+65 follows a similar pattern. For four days, it will spit out a burst or two every hour. Then it falls silent for 12 days. Then the whole thing repeats.

Astronomers with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Collaboration in Canada observed this cycle for a total of 409 days. We don't yet know what it means; but it could be another piece in the complicated conundrum of FRBs. The research has been uploaded to pre-print server arXiv, where it awaits scrutiny from other experts in the field.

It's easy to become somewhat obsessed with fast radio bursts, a fascinating space mystery that has so far defied any attempts at a comprehensive explanation.

Can’t hurt, but you better hope they’re not trying to order take in with us on the menu!

That's pretty much what I worry about. 

What did the Spanish do when they "discovered" the Americas? The resources were plundered and the indigenous flora and fauna were harvested for food.

And even the unfamiliar human races were considered "inferior" life that was acceptable to enslave. Clearly having the intelligence and culture to build structures and cultivate crops was not enough for the “superior” explorers to consider their well-being….Not being advanced enough to traverse the globe (as they had) made the natives no more evolved than beasts of burden in their eyes (worth more for their labor than as food, but still essentially beasts that could be exterminated when they are no longer of value).

"If so, they will be vastly more powerful and may not see us as any more valuable than we see bacteria," [Stephen Hawking]


Hawking's warning is rooted in the idea that an alien civilisation, especially one that can pick up our signals and understand where they're coming from, has the potential to be billions of years more advanced than us, making us an easy target to overthrow or invade.

I recall listening to Neil Degrasse Tyson on “Opie and Anthony”. They asked him if there were intelligent life in space, why hadn’t they reached out to us? 

His answer amounted to, when was the last time you tried to have a conversation with an ant on the sidewalk? Because for all we know, that’s how an intelligent life form from somewhere out there may view us. As advanced as we are, we may be absolute primaries in comparison.
