Dark Matter –“A Strange Quantum Superfluid That Flows Without Entropy”

Galaxy Protocluster

 

“A superfluid is a very interesting kind of fluid,” says physicist Justin Khoury, a professor at the University of Pennsylvania, who focuses on the interface of particle physics and cosmology. “Most substances we find in the laboratory form a solid when cooled to a low enough temperature. But a certain set of substances, such as liquid helium, effectively remain a liquid all the way to absolute zero temperature.

“We tend to think about particles as being tiny but, theoretically, there is no reason they can’t be as big as a galaxy,” says Asimina Arvanitaki, The Aristarchus chair in theoretical physics at the Perimeter Institute for Theoretical Physics in Waterloo, Canada about solving the mystery of dark matter.

“The Magnetic Cosmos” –A New Way to Detect Dark Matter

Dark Matter Filaments

 

“We still don’t know what dark matter is,” said John Terning, professor of physics at UC Davis, one of two theoretical physicists at the University of California, Davis who have a new candidate for dark matter, and a possible way to detect it. They presented their work June 6 at the Planck 2019 conference in Granada, Spain. “The primary candidate for a long time was the WIMP, but it looks like that’s almost completely ruled out.”

“Cracking the Code” –Astrophysicists Solve Decades-Old Black Hole Mystery

M87 Black Hole

 

Black holes have been described as a “one-way door out of our universe” and as “the gates of hell, the end of space and time.” That was how black holes were described by Ellie Mae O’Hagan for The Guardian at the April 10 press conference in Brussels where the first ever photograph of one was revealed. “Everything unfortunate enough to get too close to it falls in and never emerges again, including light itself. It’s the point at which every physical law of the known universe collapses. Perhaps it is the closest thing there is to hell: it is an abyss, a moment of oblivion.”

M87 Black Hole

 

The first direct image of the M87 Galaxy’s supermassive black hole that’s almost the size of our solar system required telescopes of unprecedented precision and sensitivity to give the human species a look into the unknown. The realization of this telescope – the Event Horizon Telescope – was a formidable challenge which required upgrading and connecting a planet-scale network of eight pre-existing telescopes deployed at a variety of challenging high-altitude sites, including volcanoes in Hawaii and Mexico, mountains in Arizona and the Spanish Sierra Nevada, the Chilean Atacama Desert, and Antarctica.
