Einstein Claimed: Quasar Clocks Show Universe Was 5 Times Slower Just After the Big Bang

Astrophysics of the time of the Big Bang

In a groundbreaking study, scientists used quasars as cosmic clocks to observe the early universe moving in extreme slow motion, further validating Einstein’s theory of general relativity. By examining data from nearly 200 quasars, hyperactive supermassive black holes at the centers of the first galaxies, the team found that time seemed to flow five times … Read more
