The universe is about 14 billion years old and our solar system is about 4.7 billion years old. That is, our solar system came into being about 9.3 billion years after the creation of the universe. Our Earth was formed during the same period of 4.7 billion years, ie within a few million years of the formation of the solar system, the Earth and other planets came into existence.
But our own solar system did not form as the only system of stars / planets in the entire universe, but all the stars that are seeing us with their own eyes at the moment, some planets must be revolving around them. There are. There is hardly a star that is orbiting a planet. In our own galaxy alone, there are more than one trillion stars, meaning something or other. One trillion stars must have one or more planets around it. And the process of star formation continues in different galaxies and newer stars / planets are coming into existence. But there is a universal principle of the universe that whatever is created must perish. These stars will also disappear one day or another.
Astronomers have described the extinction of our planet as a result of the Earth being consumed by a giant black hole, falling prey to a star's supernova, colliding with a very large asteroid, or its own planets. To fall prey to a consuming galaxy, a burst of gamma rays, a big rip or the death of heat in our universe. But one of the biggest reasons for the future destruction of our planet, scientists say, is the death of our sun. When it becomes a red giant, it will kill the orbiting planets near it. In this way the earth will be completely destroyed.
But there are still about seven and a half billion years left until this catastrophe. But millions of years before this catastrophe, life will end in our world. According to a scientific estimate, four billion years from now, due to the abundance of greenhouse gases on Earth, this planet will become a living hell like Venus, where it will be impossible for all life on Earth to survive. Our planet could support another 1.5 billion years of life, but gradually there will be an increase in anti-life factors. And then there will come a time when our planet will be completely dead. As the sun rises, it will disappear completely from the face of the earth. But will the universe end with the end of the earth or the sun?
No, the universe will survive, and the universe will die after many trillions of years. When new stars stop forming. By that time, many more stars would have formed and formed their own new solar system. When 5 billion years have passed since the end of the earth, an intelligent creature like us may be born somewhere on a star planet that can think exactly like us and run its own life system. But this creature will never know that a planet called Earth once revolved around a planet called the Sun, where a creature called a human ruled. At that time, our status has been completely forgotten and all our cultural traces have been destroyed along with the earth. If man did not step out of the earth, then there would be hardly any intelligent being in the whole universe who would know anything about man.
