Events appear to unfold five times slower when universe was a tenth of its present age, in effect predicted by Einstein
Astronomers have watched the distant universe running in slow motion, marking the first time that the weird effect predicted by Einstein more than a century ago has been observed in the early cosmos.
The scientists found that events appeared to unfold five times slower when the universe was a mere 1bn years old, or about a tenth of its present age, because of the way the expansion of the universe stretches time.
