Einstein predicted it, and science proved it: ‘life’ flowed five times slower in the universe when he was an infant [videos]

The strongest confirmation of Einstein’s theory that the universe The accelerating expansion at its birth was giving new astronomical research.

Oversimplification: The universe began to grow like a balloon that you inflated at first by weak inflation, but as time goes on, the inflation intensifies and the expansion of the balloon intensifies.

Accordingly, the events inside this balloon were going very slowly in the early stages and much faster as the universe got older.

Scientists have been able to track the behavior of the ‘baby’ universe and see that it was already operating in slow motion: It’s the first time that this strange phenomenon predicted by Einstein has been observed in the early universe.

• Scientists have discovered that events unfolded five times more slowly when the universe was only a billion years old, about a tenth of its current age. This slow motion is due to the way the expansion of the universe extends through time.

“We’re seeing things change five times slower than they are today,” said Geraint Lewis, professor of astrophysics and lead author of the study at the University of Sydney.

• “It’s like watching a movie in slow motion.”

According to Einstein’s general theory of relativity, astronomers should see tevents of the ancient world To speak slower than to speak. This phenomenon, known as time dilation, is driven by the expansion of the universe, as described in Einstein’s general theory of relativity in 1915.

One consequence of the expansion of the universe is that light is expanding as it travels through the universe, becoming longer in wavelength.

The longer wavelength appears to our eyes as a visible redshift: Simply put: even to the naked eye in the evening sky, older galaxies and older stars (i.e., those farther from us and therefore with a longer wavelength) appear redder than younger stars that appear to have a blue halo ( optical blueshift).

But with light, time stretches: if a distant object flashes once every second, the expansion of the universe ensures that these flashes take more than a second to reach Earth.

Astronomers have noticed in the past The stars explode in slow motion. The flash-blast and their extinction occurred at about half the speed of the universe when it was half its present age. (The universe is estimated to be 14 billion years old.)

But attempts to see the dilation of time in the early universe by observing very bright and distant galaxies called quasars have failed.

• A quasar (short for QUASi-stellAR object or QSO) in astronomy is any extremely bright, distant active galactic nucleus, which appears in visible light as a point light source (star) rather than as a larger object (galaxies). This is where the name quasars comes from, because quasi-star means “similar to a star.”

Lewis and his colleague Dr. Brendon Brewer of the University of Auckland conducted detailed statistical analyzes on 190 quasars observed over two decades and found that, unlike previous work, cosmic events seemed to unfold. Later in the early universe.

“On some level, this creates confidence that we know how the universe works. We have this picture that Einstein gave us and we test it and we test it. A good scientist doesn’t take these things for granted. You have to keep testing.”

Science has progressed by constantly testing theoretical predictions in practice, said Professor Brian Schmidt, an astronomer at the Australian National University in Canberra who shared the 2011 Nobel Prize in Physics for his discovery of the accelerating expansion of the universe.
