Researchers have made a remarkable discovery in the field of science by revealing a puzzling phenomenon in the universe. He successfully observed for the first time that the early universe operated “five times slower”.
By analyzing information gathered from quasars, celestial bodies powered by supermassive black holes located at the core of ancient galaxies, scientists were able to estimate the passage of time during the early stages of the universe.

What are quasars?
- Quasar refers to an intensely luminous center found within a galaxy.
-
The brightest quasars have luminosities that exceed the combined luminosities of all the stars in their host galaxies.
-
This extraordinary brightness enables them to remain detectable even when located billions of light years away.

Discovery: How did the researchers find out?
- A recent study has shown that time in the early universe passed about five times slower than it does in the present.
- This revelation was made by scientists who analyzed the brightness fluctuations displayed by quasars that originated from the early universe, specifically about a billion years after the Big Bang event.

Lead author Professor Geraint Lewis from the University of Sydney told BBC This discovery serves as further confirmation of our existence within an expanding universe.
As scientists have pointed out, the continuous expansion of our universe gives rise to a phenomenon called “time dilation”. Essentially, this means that time moves more slowly during a period when the universe itself was slower.
Professor Geraint Lewis said in a statement When the universe is observed to be a little more than a billion years old, time appears to pass about five times more slowly.
If one existed in the early universe, one second would subjectively feel like one second. However, from our current perspective, which is more than 12 billion years ahead in time, that early period appears to be unfolding sluggishly.
The results of the research provided confirmation of Albert Einstein’s theory of relativity, which proposed that time passes at a much slower rate in the distant universe. The study successfully identified and supported this cosmic time dilation phenomenon.

Quasars emit intense radiation in the electromagnetic spectrum, making them visible even over great distances.
Because of its remarkable brightness, the most distant quasar, which existed 13 billion years ago, remains observable today.
