Space.com reported, "One of the truly special things about fast radio bursts is this property called dispersion. As the burst signal propagates through space, it gets distorted by the very diffuse plasma that lives in the cosmos," Kiyoshi Masui, a physicist at the Massachusetts Institute of Technology's (MIT) Kavli Institute for Astrophysics and Space Research, said during the AAS presentation. "We can measure this distortion precisely, so for every one of these bursts, we know exactly how much matter it passed through," Masui said. "This carries a record within it of the structure of the universe that it has traveled through to get from the source to us. Because of this, we think that they are going to be the ultimate tool for studying the universe. With enough of them, we want to use them to map out where all the stuff is in the universe, what the structure of the universe is and how it's distributed on very large scales."
My observation. Quasars with lyman-alpha forest in their spectrums seem similar perhaps. I will wait and see here if astronomy will *map out where all the stuff is in the universe*. Should be interesting to see *all the stuff*
The link in the report to an earlier space.com report on CHIME says "The ultimate goal is to distill statistics that could rule out certain hypotheses about dark energy. For that reason, the experiment focuses on hydrogen atoms that flickered 2.6 billion to 6.8 billion years after the Big Bang. "That's when dark energy first became important," Masui said, "at the very beginning, when the expansion of the universe deviated from what we thought would happen.", ref

Using cosmology calculators, redshifts ~ 0.8 to 2.5 The size of the universe is much smaller too in the BB model, perhaps 11 billion light-years in diameter compared to 93 billion light-years in diameter today.
