The Nobel-Prize laurate, Subrahmanyan Chandrasekhar in “The Mathematical Theory of Black Holes” (for whom NASA’s Chandra Space Observatory was named), described supermassive black holes as “the most perfect objects there are in the universe –the only elements in their construction are our concepts of space and time.” Some have described these cosmic monsters as the “Gates of Hell” and others as “gateways to another universe” and the largest hard disk that exists in nature, in two dimensions. “Stupendously Large” Black Holes A Mini, Galaxy-sized Big Bang In 2020, a team of scientists, led by Emeritus Professor of Mathematics and Astronomy at Queen Mary University, London, Bernard Carr and Florian Kuhnel , who holds the Chair on Cosmology at the Arnold Sommerfeld Center for Theoretical Physics proposed that the behemoths lurking at the centers of galaxies could reach “stupendously large” sizes–where they would be like a mini, galaxy-siz ....
Posted on Feb 15, 2021 in Astronomy, Evolution, Science “It must have been an amazing sight, but we don’t want to see that again,” said Harvard astrophysicist, Avi Loeb about the comet that created the the Chicxulub crater off the coast of Mexico that spans 93 miles and runs 12 miles deep that forever changed Earth’s evolutionary history when it crashed 66 million years ago.

Since 1995 when exoplanet explorers from the Geneva Observatory in Switzerland, Michel Mayor and Didier Queloz –who were recently awarded half of the 2019 Nobel Prize in Physics for their discovery of a planet orbiting a sunlike star named 51 Pegasi– thousands of extrasolar planets have been found, including potentially Earth-like worlds, along with bizarre objects that bear no resemblance to any of the planets in our solar system. Twenty-Six Years Later… Twenty-six years later, it is now possible to capture images of planets that could potentially sustain life around nearby stars using a newly developed system for mid-infrared exoplanet imaging. In tandem with a very long observation time, a new study’s authors say they can now use ground-based telescopes to directly capture images of planets about three times the size of Earth within the habitable zones of nearby stars. ....
