Scientists puzzle over possible connection between a fast radio burst and a gamma ray burst


Readers!
 
For many reasons, mostly political but partly ethical, I do not use Google, Facebook, Twitter. They practice corrupt business policies, while targeting conservative websites for censoring, facts repeatedly confirmed by news stories and by my sense that Facebook has taken action to prevent my readers from recommending Behind the Black to their friends.
 
Thus, I must have your direct support to keep this webpage alive. Not only does the money pay the bills, it gives me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.

The uncertainty of science: In trying to explain the relatively new mystery of fast radio bursts (FRB), of which only about 20 have been detected and of which very little is known, scientists are intrigued by a gamma ray burst (GRB) that apparently occurred at the same time and place of one FRB.

Seeing the FRB event in a different wavelength would normally help astronomers better understand the FRB The problem is that this particular GRB only makes the mystery of FRBs more baffling.

One puzzle is that the two signals portray different pictures of the underlying source, which seems to be as much as 10 billion light years (3.2 gigaparsecs) away. Whereas the radio burst lasted just a few milliseconds, the γ-ray signal lasted between two and six minutes, and it released much more energy in total than the radio burst. “We’ve pumped up the energy budget more than a billion times,” says study co-author Derek Fox, an astrophysicist at Penn State.

This has big implications for the FRB’s origin. One leading theory suggests that FRBs are flares from distant magnetars — neutron stars with enormous magnetic fields that could generate short, energetic blasts of energy, and do so repeatedly, as at least one FRB is known to do. Although magnetars are thought to produce γ-rays, they would not emit such high energy and over such a long time, says Fox. “This is a severe challenge for magnetar models,” he says.

    Dang it!!! I thought all science was settled, now this!!! /sarc

    That’s OK, Stosh. They only told us that climate science is settled.

    But that does not explain why climate scientists are trying to figure out better climate models — you know, models that could have predicted the “pause.”

    (I put the word “pause” in quotes, because we really do not know whether the temperatures will continue to climb, due to us still coming out of the Little Ice Age — thus it would be a pause in the recovery — or if they will begin to fall, ushering in the next glacial period of the secular Ice Age — thus it is not a pause at all but a calm before the freeze — or if there is something else going on with Earth’s climate that we still can’t predict, because climate science is not as settled as the politicians would have us believe.)
