New, high-resolution observations of a faint, fluffy galaxy suggest that dark matter’s not as ubiquitous as scientists thought.

Astronomers were first alerted to the star’s unusual activity 130 days before it went supernova. Bright radiation was detected in the summer of 2020 by the University of Hawaiʻi Institute for Astronomy Pan-STARRS telescope on Maui’s Haleakalā.

Then, in the fall of that year, the researchers witnessed a supernova in the same spot.

They observed it using the W.M. Keck Observatory’s Low Resolution Imaging Spectrometer on Maunakea, Hawai’i, and named the supernova 2020tlf. Their observations revealed that there was material around the star when it exploded — the bright gas that the star violently kicked away from itself over the summer.

Exactly what existed before the birth of our own Universe remains a mystery, but that is not stopping some physicists from trying to figure it out.

According to this site there are 100 billion blackholes in our universe.

Information, virtual journeys, and simulations about black holes from the Space Telescope Science Institute.

If the finding really is the result of new fundamental particles then it will finally be the breakthrough that physicists have been yearning for for decades.

When CERN’s gargantuan accelerator, the Large Hadron Collider (LHC), fired up ten years ago, hopes abounded that new particles would soon be discovered that could help us unravel physics’ deepest mysteries. Dark matter, microscopic black holes, and hidden dimensions were just some of the possibilities. But aside from the spectacular discovery of the Higgs boson, the project has failed to yield any clues as to what might lie beyond the standard model of particle physics, our current best theory of the micro-cosmos.

So our new paper from LHCb, one of the four giant LHC experiments, is likely to set physicists’ hearts beating just a little faster. After analyzing trillions of collisions produced over the last decade, we may be seeing evidence of something altogether new – potentially the carrier of a brand new force of nature.
