New research confirms that the passage of time moved five times slower after the Big Bang than it does now due to a phenomenon known as “Time Dilation.”
A century ago, famed Theorist Albert Einstein predicted that time would have indeed moved slower the closer one moves back toward the Big Bang. But the latest discovery by a pair of Australian researchers using quasars as “clocks” is the first to prove definitively Einstein was right.
“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 study lead author, Professor Geraint Lewis from the School of Physics and Sydney Institute for Astronomy at the University of Sydney in a press release announcing the new discovery.
Einstein’s Theory Was Unprovable Until Recent Advances in Astronomy
When laying out his theory of General Relativity, Albert Einstein made a startling and controversial pronouncement. Due to a phenomenon, he called “time dilation,” time itself should have moved as much as five times slower than it does now in the millennia after the Big Bang.
Previously, astronomers were able to witness the telltale signs of this time dilation about halfway back to the Big Bang, or about 7 billion years after the birth of the universe, using the light emitted by supernovae. But until recently, that was as far as they could look “back in time.”
“Where supernovae act like a single flash of light, making them easier to study, quasars are more complex, like an ongoing firework display,” said Lewis.
Alongside Australian astro-statistician Brendon Brewer, Lewis was finally able to examine whether or not time did indeed move slower in the distant past and if this period of extreme time dilation lasted for as much as a billion years or more after the Big Bang.
“What we have done is unravel this firework display, showing that quasars, too, can be used as standard markers of time for the early…
