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.
“There are precious few fossil relics of the early Universe,” Brian Keating, Chancellor’s Distinguished Professor of Physics at UC San Diego, and author of Think Like a Nobel Prize Winner,” told The Daily Galaxy. “Just after the Big Bang,” Keating explained, “came the epoch of Big Bang nucleosynthesis, ending a few minutes later. The Cosmic Microwave Background, the universe’s oldest light, came about 380,000 years later. Then the great cosmic darkness began. That darkness had to end, or else we would not be here asking what caused the Universe to be so dim.
