It has been discovered that time flows more slowly in quasars in the early universe.
This was predicted by Einstein. According to his General Theory of Relativity, time flows more slowly near objects with greater gravity. When this fact is combined with the fact of cosmic expansion, the answer is that time in the early universe was slower than it is now.
In other words, this discovery is just another discovery that “Einstein was right again,” explained Geraint Lewis, an astronomer at the University of Sydney.
He and Brendon Brewer, an astronomer at the University of Auckland, have now presented their findings. But this is nothing new, and it has been confirming what astrologers have been predicting for years.
For years, astronomers have predicted that time moves more slowly around quasars. However, attempts to prove this fact have failed.
Quasars are supermassive black holes. These supermassive black holes are often found at the centers of large galaxies.
Surrounding these quasars is a large vortex of gas that flows into the quasar. The bright light comes out due to the temperature of this eddy. Because the size of this vortex is small, the brightness of the light emitted from it changes very quickly. The brightness of these quasars changes daily.
This brightness changes daily, making it easier to observe them.
But these quasars are supermassive black holes that existed at the beginning of the universe. So the light from them takes about 12 billion (12,000 million) years to reach us. During this period, the universe has expanded many times.
This means that the quasars that we see now are what we saw when the universe was small 12 billion years ago.
Astronomers Lewis and Brewer studied 190 quasars over 20 years of observational and recorded data. This data was collected from the Sloan Digital Sky Survey (SDSS), Pan-STARRS, and the Dark Energy Survey.
They studied the changes in brightness of these quasars in detail. In this study, they found that the light change of quasars early in the universe is slower compared to the light change of later quasars.
According to their calculations, they found that the time of quasars during the first 1,000 million years of the universe was about five times slower than the current time on Earth.
But for these quasars, time is not slowing down inside them. In fact, the universe itself, where these quasars were at that time, was flowing slowly. From their point of view, time is flowing normally, and from our point of view, time is slow at that time.
In other words, the universe was smaller and denser at that time. The material objects will be closer to each other than now, so the attraction between them will be greater. Taken together, it becomes clear that time was much slower in the early universe.
This finding is not just another piece of evidence that confirms Einstein’s theory. This is further evidence for the theory that our universe is gradually expanding.
