Early universe five times slower, study finds, adds to space expansion proof

Big Bang, would take five of those of the present day universe before it passed, a new research has found, unlocking one of the Einstein's expanding universe's mysteries. «Looking back to a time when the universe was just over a billion years old, we see time appearing to flow five times slower,» said lead author of the study, Geraint Lewis, University of Sydney, Australia. «If you were there, in this infant universe, one second would seem like one second — but from our position, more than 12 billion years into the future, that early time appears to drag,» said Lewis. While Einstein's general theory of relativity says that the more distant the object being observed, such as an ancient universe, the slower it runs than the present day, peering back that far in time has proved elusive. Examining details of 190 quasars, or hyperactive supermassive black holes at the centres of early galaxies, over two decades, the astronomers rolled back the time horizon to a tenth of its current stage and confirmed that the universe appeared to speed up as it aged. The study is published in the journal Nature Astronomy.

Astronomers find evidence of universe's 'background noise', first predicted by Albert Einstein

«Thanks to Einstein, we know that time and space are intertwined and, since the dawn of time in the singularity of the Big Bang, the universe has been expanding. »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,» said Lewis. Lewis and team combined the observations from quasars taken at different colours to standardise the 'ticking' of each
