Scientists have peered into the early days of the universe, when it was about 1 billion years old, and discovered that things moved in slow motion compared with now.
The finding supports Albert Einstein’s general theory of relativity, which suggests that the distant universe moved much more slowly in the past.
Observing quasars over time allowed a team of astronomers to see how the universe seemed to speed up as it aged. The results of the study published Monday in the journal Nature Astronomy. Research shows that the universe is expanding, and at an accelerated rate, too, which scientists are still trying to understand.
“This expansion of space means that our observations of the early universe should appear to be much slower than time flows today. In this paper, we have established that back to about a billion years after the Big Bang.”
