Ancient Radio Waves Distorted-Chilled by Dark Matter?

Search for first stars uncovers 'dark matter,'
American Friends of Tel Aviv University, February 28, 2018.

UPDATED BELOW

This is an interesting story, kind of like how two dudes stumbled onto the Big Bang while trying to fix an ATT antenna and reciever. They found it, but they had no idea what they found. It took another team to point out the pertinence of their find.

WIKI; Discovery of cosmic microwave background radiation

The initial data containing Dark Matter influences was collected during an "attempted" search for the Universe's earliest stars, probing ancient radio waves generated merely 180 million years after the Big Bang, observing the Universe's earliest stars they found forming in, and lighting up, a primordial soup of hydrogen.
This generated an earlier paper than this report, referred to below. These radio waves contained an unexpected surprise, explained later by a theorist, which generated a second paper. Our article above reflects both papers, a bit of the data of the first, organized by the analysis of the second. The author of the second paper:

"Dark matter is the key to unlocking the mystery of what the universe is made of."

"...dark matter is inferred from its strong gravity, but we have no idea what kind of substance it is. Hence, dark matter remains one of the greatest mysteries in physics." Yup, we knew that...nothing like a good setup!

The "...radio wave signal at a frequency of 78 megahertz" detected was different than expected. This signal indicated cooler temperatures than expected. Something had unexpectedly cooled the primordial Hydrogen "soup" of our early universe, which the second paper explains with a low-mass dark matter particle.

"This insight alone has the potential to reorient the search for dark matter."

Though this analysis of ancient radio waves did not "find" dark matter, it found what may well have been another aspect of its effects in the very, very early universe. This narrows the field of search for the source of this still unexplained gravity.

NEXT STEP
This research, "... predicts that the dark matter produced a very specific pattern of radio waves that can be detected with a large array of radio antennas. One such array is the SKA, the largest radio telescope in the world, now under construction."

Stay Tuned!

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
