Like Gravitational Waves (GWs) and Gamma-Ray Bursts (GRBs), Fast Radio Bursts (FRBs) are one of the most powerful and mysterious astronomical phenomena today. These transient events consist of bursts that put out more energy in a millisecond than the Sun does in three days. While most bursts last mere milliseconds, there have been rare cases where FRBs were found repeating. While astronomers are still unsure what causes them and opinions vary, dedicated observatories and international collaborations have dramatically increased the number of events available for study...
Despite their mysterious nature, FRBs are ubiquitous and the best estimates indicate that events arrive at Earth roughly a thousand times a day over the entire sky. None of the theories or models proposed to date can fully explain all the properties of the bursts or the sources. While some are believed to be caused by neutron stars and black holes (attributable to the high energy density of their surroundings), others continue to defy classification. Because of this, other theories persist, ranging from pulsars and magnetars to GRBs and extraterrestrial communications.
CHIME was originally designed to measure the expansion history of the Universe through the detection of neutral hydrogen. Roughly 370,000 years after the Big Bang, the Universe was permeated by this gas, and the only photons were either the relic radiation from the Big Bang – the Cosmic Microwave Background (CMB) – or that released by neutral hydrogen atoms. For this reason, astronomers and cosmologists refer to this period as the “Dark Ages,” which ended roughly 1 billion years after the Big Bang as the first stars and galaxies began reionizing neutral hydrogen (the Reionization Era).

That explains why there are so many voices.
“[FRBs] arrive at Earth roughly a thousand times a day”
Wow, only a few years ago they were thought to be extremely rare and infrequent one-off occurrences.
It says “Sunday! Sunday! Sunday!”
I think it’s for a monster truck rally.
The Big Bang Theory got busted.
No, the BBT is still going strong.
And they are all saying, “Lock her up!”
If they’re not, they should be.
“Send More Chuck Berry”
It’s when some alien botches that tricky “gear”shift maneuver on the older hyperdrives, the manual shift ones, that causes this. Those things should be outlawed.
Truly these signals must be coming from a woman alien. Now she’s nagging 🤪 🛸👽
“Send More Chuck Berry”
WTF...Do they think there was more than one Chuck Berry?
Navigational beacons of course. Shhes

Well there was his cousin, Marvin Berry.

Yeah, it took the Xeelee a bit to get them set up, before they decided that the Dark Matter entities where set on destroying or reducing all suns, except the most stable for their breeding ground, and before they set up the Great Attractor to open a portal to escape to a different universe.
