Hotel Mars features Dr. Matthew Graham on "an extremely luminous flare recorded from a supermassive blackhole only 10 Billion light years from Earth !
Description
John Batchelor and I welcomed Cal Tech Professor Matthew Graham to Hotel Mars to discusses the most powerful black hole flare ever recorded, equal in brightness to about 10 trillion suns known and referred to as an Active Galactic Nucleus (AGN). It is believed and our guest explained that material falling into the supermassive black hole forms an accretion disc which releasing both massive and intense radiation. This 10-billion-year-old event (10 billion light years from Earth) was detected using computer cameras and multiple terrestrial telescopes. Dr. Graham explained that these black holes are ancient “seeds” of galaxies, acting as cosmic vacuum cleaners, such as when a large star gets shredded. This Hotel Mars program was in two segments totaling about 19.5 minutes.
