Scientists have made a significant breakthrough in understanding the nature of time in the early universe by confirming that time appeared to run five times slower in the distant past. This extraordinary phenomenon has been revealed through the use of quasars, extremely bright cosmic objects, as “clocks” in a groundbreaking study.
Led by Geraint Lewis, an astrophysicist at the University of Sydney, the research team utilized the theory of relativity proposed by Albert Einstein to predict that the expansion of space should result in a slower passage of time in the distant universe. Previous studies had relied on supernovas, bright exploding stars, as cosmic clocks to demonstrate that time ran twice as slowly when the universe was half its present age.
