Anonymous users2024-02-09The sun will age five billion years later, but it is possible that humanity will die out before that day. We all know that the hottest and most topical movie in 2018 is "The Wandering Earth". This movie is starring Wu Jing, Zhao Jinmai and many other well-known actors; tells the story of a scene in the context of "the sun goes out";
The story of human beings carrying the earth and wandering in the vast space in search of their next home. Although it may seem that this is a bit "scary"; However, according to current scientific theories, the sun is at least 5 billion years old before it can enter the aging period. What does this mean?
Movies are just movies after all.
But will humans really be able to reproduce five billion years later? I'm afraid it's a question that no one can say for sure. Although our science and technology are constantly booming, the destruction of the natural world and the exploitation of the earth's resources seem to indicate that human beings will one day "kill themselves";
Moreover, the two "threats" of artificial intelligence and extraterrestrial civilization also restrict our development. It is said that NASA has discovered an unknown civilization that has reached the level of "planet" technology hundreds of thousands of light-years away; It is not known what they think about the planet.
The only thing we know is that if a super-civilization does wage a colonial war against humanity, then we will have little power to resist. Moreover, the famous physicist Mr. Stephen Hawking once predicted that 2045 will be the year that determines the fate of mankind!
Compared with the illusory five billion years later, this day is obviously more realistic! In 2045, the average global temperature will increase by three degrees Celsius, and at that time, Asia and Europe may face the dilemma of sinking, and all the icebergs in the north and south poles will melt!
If we don't take action, we don't have to wait for the sun to reach the age stage, and human civilization will die out early! Our destiny is in our own hands!

Anonymous users2024-02-07No. Five billion years is the ideal survival time for human beings, but it is not yet possible to judge whether human beings will experience major changes in these 5 billion years.

The end of the Earth : Geologists speculate that the sun has been shining for 5 billion years. It is estimated that in another 5 billion years, most of the sun's hydrogen will polymerize into heavier helium, helium needs a higher temperature to polymerize into carbon, because helium is heavier, its gravitational pull will be stronger, so that the pressure in the center of the sun will increase, when the gas pressure increases, according to the gas law, the temperature will automatically increase, when the sun is mostly helium, its central temperature will increase by 10 times to the present, reaching 100 million degrees, helium will polymerize into heavier carbon, and then due to gravity will produce a higher temperature and polymerize carbon into nitrogen. >>>More
Not 500 million years from now, but billions of years from now. >>>More
The sun has been burning for 5 billion years, but it has not been extinguished because the sun does not release light and heat by burning matter, or through chemical reactions, but through the release of energy。This energy release is formed by a very huge nuclear fusion, we all know that nuclear fusion, which is currently one of the most powerful ** in the world, such as a nuclear bomb, and the energy it produces by nuclear fusion is very huge, which is unimaginable to human beings. >>>More
Because after a billion years, the sun will become very irritable, which will cause great changes in the earth's environment, so human beings will only have a billion years.
What is happening inside the sun is nuclear fusion.
The primordial heat of the sun is due to its internal pressure. According to the principle of the law of gravitation, the greater the mass of an object, the greater its gravitational pull. In the early years, when the sun snowballed, as the mass increased, the gravitational pull became stronger, the more material it attracted around it, the more mass was increased, and so on, the mass of the sun became larger and larger. >>>More
