Time ran slowly in the early Universe, just as Einstein predicted

Scientists have discovered that time ran five times slower in the early Universe, just 1.5 billion years after the Big Bang, compared to the present day. This confirms Einstein’s theory of relativity, which predicted that time would progress differently in the early, hotter, and denser cosmos. The discovery was made by astrophysicists Geraint Lewis and Brendon Brewer, who observed cosmological time dilation in quasars, the active centers of galaxies. The research demonstrates that the expansion of space itself is the cause of the time dilation, proving that it is a fundamental aspect of the Universe. This finding provides important insight into the nature of spacetime and supports current theories of cosmology and relativity.
