For the origin of the universe, I believe many friends know that modern science believes that the universe originated from the singularity explosion 13.8 billion years ago. With the rapid expansion of the universe after the big bang, all kinds of celestial bodies are constantly forming. As time goes on, there is now a rich and colorful universe.
We all know that before the birth of the universe, there was no celestial body, no matter. If the universe originated from the big bang of a singularity, then we can see the singularity as a collection of infinite energy. It was this infinite energy thing that had a big bang under the action of mysterious forces, in which the energy was quickly released, and then there was the present universe.
Therefore, any matter and material objects in our universe were continuously formed after the big bang. At that time, there were only hydrogen, helium and a small number of other elements that were first converted from energy. I believe many friends know Einstein’s mass energy equation. According to the theory of mass energy equation, energy and matter can be transformed into each other.
As long as the energy is strong enough, any substance can be transformed under other conditions. Therefore, the matter of the early universe was transformed from the super energy generated by the big bang, of which more than 99% were hydrogen and helium. With hydrogen and helium, there will be the birth of stars later, because the main components of stars are hydrogen and helium.
It can be seen that theoretically, there can be no celestial body older than the age of the universe, which I believe my friends can understand. But what if scientists find an object older than the age of the universe? Maybe someone will say, how is that possible? If there is such a thing, it will surprise countless scientists and doubt many things in the universe.
However, the universe is so big that the more impossible things are, the more likely they are to appear and hit us in the face. This object, which is older than the universe, was discovered by scientists. It is a star named HD 140283. This star is about 190 light-years away from earth, and it’s not very far away from us.
This star was discovered by scientists as early as a century ago. When scientists discovered it and calculated its age through some observation data, it surprised the scientists at that time that its age was about 14 billion years. It’s not surprising that a star can live for such a long time. Small mass stars can theoretically reach this life span.
Scientists are surprised that it is older than the age of the universe. Modern science believes that the big bang happened between 13.7-13.8 billion years. If the age of this star is about 14 billion years ago, it means that it existed before the origin of our universe. Isn’t that a fantasy? But the fact is in front of us, let us have to believe.
At first, scientists wondered if our calculations were wrong? But later, scientists have been observing and studying this star for as long as 100 years. Through more observation data and calculations, the final conclusion is still about 14 billion years, even if there is an error, it is about 800 million years.
Some people may say that if the scientist’s calculation error is 800 million years, then the age of the star is 13.2 billion years, isn’t it younger than the age of the universe? So, it’s normal that it was born in the first stars of the big bang? Roughly speaking, it seems reasonable, but if we carefully analyze the birth time of the earliest stars in the universe, maybe you don’t think so.
After the big bang, hydrogen and helium were first formed, followed by the rapid expansion of the universe. This period is the “dark era” of the universe, without any light. It was not until the first stars and galaxies came out that the so-called “Dark Age” of the universe ended. These stars not only light up the night sky with the light they emit, but also clear the haze of hydrogen atoms that used to fill the universe.
From the earliest hydrogen and helium to the first stars, it takes a long time to form, not very soon. According to the observation and research of scientists, the earliest stars in the universe were born about 13 billion years ago, which is about 800 million years after the big bang.
But now scientists have observed HD 140283. Even if the error reaches 800 million years, its age is 13.2 billion years. The universe is unlikely to produce stars at this time, so how did this ancient star come from? In this regard, scientists are also very confused. You know, scientists have observed and discovered some ancient stars in the past half century. These stars may also be the first batch of stars in the universe. Their ages are about 13 billion years.
HD 140283, on the other hand, has a normal age of 14 billion years. Even if the error is adjusted to 800 million years, its age is 13.2 billion years. Obviously, if our universe really originated 13.8 billion years ago, then this star may not be a celestial body in our universe.
Seeing this makes many people think of the multi non cosmology. I believe many friends know that scientists once proposed the multi cosmology. This theory holds that the universe is not unique, but there are many. Under our universe, there is a vast space, in which there are a large number of other universes.
If the multi cosmology theory is correct, HD 140283 may be a celestial body from other universes. It inadvertently entered this universe just after the big bang of our universe, and then has been existing until now. In addition, there is another possibility that has something to do with the origin of the universe.
Scientists have another explanation for the origin of the universe, that is, the reincarnation of the universe. Some people think that the universe also has a starting point and an end point. When the universe expands to a certain extent, it will continue to collapse, and finally restart the universe, giving birth to a new universe. If so, then our universe may be a continuation of the last one. HD 140283 star may be the celestial body of the last universe. As long as it is not destroyed by chance, it will continue to survive with the birth of the new universe.
Of course, these are just our guesses. What’s the matter with HD 140283? It also needs the continuous exploration and research of scientists. If it is really the celestial body that gave birth to our universe, then its age is 14 billion years. Does that mean that human beings are not right about the origin time of the universe now? It is possible that the origin of our universe was unknown as far back as 13.8 billion years ago.
