ET, calling Earth??

Fast radio bursts, or FRBs – brief but very powerful blasts of radio waves – are one
of the most unusual phenomena ever discovered in deep space. Scientists don’t
know what causes them. Most are just seen once, while a few have been seen to
repeat. But none have been observed to repeat on a regular, cyclic basis. Until now.

As reported by Christopher Crockett in Science News on February 7, 2020,
scientists using the Canadian Hydrogen Intensity Mapping Experiment (CHIME)
radio telescope in British Columbia, Canada, have found that one of the repeaters
does have regular bursts, in a cycle of about 16 days. This is the first time such
regularity has been seen in an FRB. The discovery was made by Dongzi Li, an
astrophysicist at the University of Toronto, and her colleagues. ...

While FRBs are probably a natural phenomenon, like pulsars, it is tempting to
wonder if they could be from an extraterrestrial intelligence.
The newly-discovered periodicity in this one FRB is intriguing, but isn’t proof in
itself. The fact that they originate from so many different places among other
galaxies would seem to argue against them simply being from a single advanced
civilization. But even if they are natural, they must be a type of exotic phenomena
never seen before, and utterly new to science, and that is exciting.

The amount of energy required to create a detectable signal 3 million light years away is past stellar level.

I read in another article that the energy of each burst would be equivalent to 80 years worth of output from the Sun!

And I had a flashback to Christopher Glenn and In The News.

all who would be called good
must suffer with him.

Last I read (getting to be a while ago now...) was that the then-current theory was either a rotating black hole (with a radio frequency and x-ray "jet" emanating from the poles, and it rotating with a precession that aligned that jet towards us regularly)... or a neutron star doing much the same thing.
Given the frequency, a neutron star makes the most sense.

Aliens would use spread spectrum communications instead of blasting out a massive amount of energy.

Or maybe REALLY SLOW Amplitude Modulation?
