"Gateways to Eternity" --Black Hole Discoveries Lead to Three 2020 Nobel Prizes in Physics


Black holes are “a one-way door out of our universe,” said Event Horizon Telescope director and astronomer Sheperd S. Doeleman of the Harvard Smithsonian Center for Astrophysics about discoveries of the enigmatic cosmic objects that led to three 2020 Noble Prize awards in physics. These “seductive dragon of the universe” described by astronomers as the “gates of hell, the end of spacetime and gateways to eternity” ”after the iconic image of the M87 galaxy supermassive black hole was unveiled in 2019, were first named “black holes” in 1983 by Princeton quantum physicist John Archibald Wheeler.  (more…)

“Somewhere, on some other planet orbiting some very distant star, maybe in another galaxy, there could well be entities that are at least as intelligent as we are, and are interested in science. It is not impossible,” says Nobel-Prize laureate, physicist Murray Gell-Mann. “I think there probably are lots. Very likely none is close enough to interact with us, but they could be out there very easily.”

New findings by NANOGrav, the North American Nanohertz Observatory for Gravitational Waves, could become the “discovery of the century” if the data has been generated by a network of giant filaments –cosmic strings–left over from the birth of the universe.

“Eerie Orange Shadow” –M87s Iconic Black Hole Image Tests Einstein’s Theory that Gravity is Matter Warping Spacetime

M87 Black Hole


In a new test from the Event Horizon Telescope using the first image ever taken of the supermassive black hole at the center of massive galaxy M87 the size of our solar system imaged for the first time ever by the Event Horizon Telescope (EHT) on April 10, 2019 and described by the EHT team as — “paradoxical, intriguing, frightening” and “the end of spacetime– has shown that the size of the black-hole’s shadow was consistent with the size predicted by Einstein’s theory of general relativity—the idea that gravity is matter warping spacetime. Einstein’s theory remains mathematically irreconcilable with quantum mechanics, the scientific understanding of the subatomic world.

"300-Times Size of the Milky Way" --Big-Bang Spider's Web of Galaxies Powering Supermassive Black Hole


“We believe we have just seen the tip of the iceberg, and that the few galaxies discovered so far around this supermassive black hole are only the brightest ones,” said Barbara Balmaverde, at The National Institute for Astrophysics (INAF) in Torino, Italy about the discovery by astronomers using the ESO’s Very Large Telescope (VLT) of six galaxies in a cosmic “spider’s web” of gas extending to over 300 times the size of the Milky Way around a supermassive black hole –those “strange galactic monsters, for whom creation is destruction, death life, chaos order”–at the dawn of time when the universe was only 0.9 billion years old.

“Perhaps the most significant sign of the existence of dark matter, however, is our very existence,” observes Harvard theoretical physicist, Lisa Randall in Nature about the elusive substance that permeates the universe, exerts detectable gravitational influences, and yet eludes direct detection. “Despite its invisibility, dark matter has been critical to the evolution of our universe and to the emergence of stars, planets and even life.”
