Time's Mind-Bending Secrets: From Slower Universes to Wibbly Wobbly Time

Astronomers have observed time moving five times slower in the early universe compared to the present day, confirming a prediction made by Albert Einstein in his theory of general relativity. By studying data from quasars dating back to when the universe was just 1 billion years old, researchers found that the expansion of the universe causes light emitted from distant sources to stretch, resulting in a time delay between light pulses. This discovery provides further evidence for the interconnection of time and space and confirms the validity of Einstein's theory.
