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).

Yeah, that can happen when research continues.
And no more D’s!
But, but, but...wasn’t the science settled?
Yeah, when I was in the service someone told me about them, I think he was Pvt Idaho.
“Where’s the kaboom?”
No, that’s a political view on both ends of the spectrum.
My remark was a wry joke.

This is the way the world ends
This is the way the world ends
This is the way the world ends
Not with a bang but a whimper.
No kaboom, just a whine

She was neither.
