@sonhouse FRBs would still be mysterious even if they were closer, although the mystery would be a bit different. I think the distances are estimated on the basis of "dispersion", a difference in arrival times of burst components. Dispersion measures, taken at face value, indicate cosmological distances.

I wonder what happens to a fast rotating pulsar that slows down and has enough mass to turn into a black hole. What does a neutron star supernova look like?

What if the red shifting of all EMR changed the intensity of EMR. Suppose a red shift of 1 doubled the intensity, a red shift of 3 tripled it, etc.? Could this possibly be an explanation for some the unexplained extreme gamma rays and radio ways we observe from the distant universe?

Just saying something could have developed one ... strange how it found a hole through our galaxy

What about the possibility the bursts come from closer in, meaning less energy would have been involved. like a few hunded lightyears instead of thousands or tens of thousands of light years?

They already confirmed the source distance recently as very far.

It's just a side effect when transitioning to warp drive, nothing to worry about.

Speaking from a position of ignorance of the details and the physics, could they be relate to reconnection of galactic magnetic field lines ?

"the researchers found that the FRB had taken an interesting path through the Milky Way to make its way to us—a hole of sorts that, prior to the detection of the FRB, was unknown."

What is this supposed to mean?

I'm waiting for more data.

One type of FRBs has been identified as emanating from the magnetrons of microwave ovens when the door is opened during a heating cycle, caused by the collapse of the magnetic field around the magnetron. These were called "perytons." Yes, really. Go look it up.

Worrisome for the sentients who live in subspace. Ban warp drive now!

Hence why the plasma ignoramuses (astrophysicists) see this as such a mystery, they are oblivious to electricity in plasmas and the various phenomena that is created.

Rogue wave ? Just like the mega waves that forms at random points on the sea?
It may be constructive interference from one or more e-m sources
If so, an origin point will never be found because it does not exist.

So what is the Fourier spectrum of the radiation? This will define the size of the oscillators.

The fourier spectrum gives the frequencies contained (and their respective power within the signal) - not the magnitude of the entire oscillation.

If you just want the magnitude of the oscillation then look at the signal itself. No need for a fourier transform.

The way I get it from the paper is that the polarization of light is affected by them magnetic field and the free electrons in the intervening space. This "rotation measure" is usually just dependent on a constant factor (RM) and the square of the frequency. Since the FRB is close to the galactic plane some polarization from the galactic magnetic field/free electron columns is expected. However, RM seems to be surprisingly low (in a range around zero with 95% confidence) for this FRB.
So it looks like the line of sight to this event is through a 'hole' ( i.e. region of low magentic field, one which includes a field reversal, or low electron column density...or any/all of the above))

Thanks for the clarification. That point is an important detail in this story. Bob Yirka seems to have preferred to write a story about "mystery", not about clarity.
