The universe is only 13.8 billion years old, but scientists have discovered a 140-year-old star. What happened?

13.8 billion years ago, a dense &34;singularity&34; triggered a big bang, after which the universe Was born. Subsequently, the universe began to expand, and all the matter in the universe was also produced. These matter evolved over a long period of time to form the universe we see today. Many people may not be aware that the cosmology established by mankind today is based on the big bang theory.

Scientists use satellite observations and collected cosmic microwave data Analysis revealed that the universe was born about 13.8 billion years ago. At that time, the universe was still a fatal scorching”singularity”. After developing to a certain extent, this singularity exploded and the universe was born. This view not only allows us to know how the universe was born, but also brings us an important message, that is, the age of the universe today, which should be 13.8 billion years.

Since the true age of the universe is 13.8 billion years, the universe Any celestial body in should be less than 13.8 billion years old. In fact, scientists have always found this to be true. The ages of the major celestial bodies in the universe are generally much younger than those in the universe, such as 5 billion years for the sun, 8 billion years for the Milky Way, and 4.6 billion years for the Earth. And the Moon’s 4.6 billion years.

However, something unexpected, scientists are actually A star older than the age of the universe was found in the center of the universe. It is understood that the age of this star is about 14 billion years, which is 1 to 2 years older than the universe. What is going on?

HD 140283 star

European Space Agency’s Libra, named HD 140283 star, and it is about 190 light years away from the earth. It is understood that the planet is a critical celestial body between a main sequence star and a giant star. In fact, as early as the last century, scientist Howard Bond discovered the planet with the Hubble telescope and measured its true age to be 13.9 billion years.

I believe that many people have doubts in their minds. How do scientists know the age of stars? In fact, when scientists discover a star in the universe, they will first determine the distance from the earth, and then measure the brightness of the star after determining the distance. Once the brightness is determined, scientists can calculate the consumption of hydrogen to deduce the star Specific age.

Back to the topic! If the age of this star is really 13.9 billion years, then this may indicate that our cosmic system here is wrong. Calculated according to the human cosmic system, there can be no objects older than 13.8 billion light-years in the universe, and there should be no Objects older than the age of the universe exist, but what about this planet?

In this regard, some scientists believe that it may be calculated The problem is that the age of this star may not be that old. It may be the first planet born in the universe, so its age will be similar to that of the universe. In addition, some scientists have also proposed new conjectures. If this universe is older than the universe, then it may not be a celestial body in this universe, but from Parallel universe.

Scientists have always believed in the existence of parallel universes , And recently NASA has indeed found evidence to confirm the existence of parallel universes. In theory, parallel universes are independent and interrelated. Perhaps the star HD 140283 really comes from a parallel universe. What is your opinion on this?
