Today’s stories range from Strange new Higgs particles beyond the Standard Model could explain shocking W boson result to New theory explains why aliens are avoiding Earth to Neighboring alien planets may Be in ‘Early-Earth’ stage of Life to NASA’s “Point of No Return,” and much more. The Galaxy Report” brings you news of space and science that has the capacity to provide clues to the mystery of our existence and adds a much needed cosmic perspective in our current Anthropocene Epoch.
Astronomers have known since the 1990s that planets exist around pulsars. It’s a reasonable hypothesis that planets might also exist around black holes, which have a weaker impact on their local environment than rotating neutron stars. In 2019, Harvard astrophysicist Avi Loeb and NASA’s Jeremy Schnittman proposed that inhabited planets might exist around the black holes harbored at the center of most galaxies. Such planets are similar to the fictional water-world planet Miller, the closest planet in the star system orbiting the supermassive black hole, Gargantua, in the movie Interstellar.
“The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time,” said astrophysicist Subrahmanyan Chandrasekhar. Chandrasekhar first demonstrated that at the end of a star’s life, if its remaining mass is greater than 1.4 times our sun’s mass, then its ultimate fate will be rather strange, collapsing under its own gravity to reach enormous density as a neutron star or black hole.
Black holes are usually formed in the explosive deaths of massive stars. In dense environments like globular clusters and the cores of massive galaxies, several black holes can merge together, forming an even more massive black hole. In addition, black holes at the centers of galaxies can accrete infalling gas, gaining in mass and size. If this process continues for billions of years, the black hole can become a supermassive black hole, like the one located at the center of our Milky Way Galaxy, weighing in at four million times the mass of the sun.
Observational cosmologists are actively searching for a “new physics” that may solve the enduring enigma of our rapidly expanding Universe. Quasars are the ancient cores of galaxies where a supermassive black hole is actively pulling in matter from its surroundings at very intense rates may old the clue to solving the mystery.
