The sun will eventually be destroyed, how can human beings continue human civilization?

Humans need to get their energy from the sun to live on Earth. The energy from the Sun is not endless, and in about 5 billion years the Sun will turn into a red giant star and begin its final journey of life. Before the Sun becomes a red giant, there is a possibility that the Earth will no longer be suitable for human life, and humanity will need to take some measures to survive.

What can humans do? It seems a bit funny that we are here to worry about humanity in 3 billion or 4 billion years, when the level of human technology is unimaginable. But we can also imagine the technology that is currently visible to humans.

The method given in the science fiction work "The Wandering Earth" is to build more than 10,000 huge planetary engines on the earth and escape to Proxima Centauri, which is 4 light-years away. This method is still very far from humans, but some scientists have thought about pushing the Earth's orbit farther away from the sun. Before the Sun is about to turn into a red giant, pushing the Earth to the orbit of Mars will not be a problem if humans can survive on Earth for a longer period of time, for an additional 100 million years.

There are also scientists who envision using powerful laser beams on Earth to turn over and stir up the material on the sun. Nuclear fusion on the sun takes place near the center of the sun, and when the hydrogen inside the sun is consumed, there is still a large amount of hydrogen on the outside for nuclear fusion. The lifetime of the sun can be extended by flipping the external hydrogen near the center of the sun with a powerful laser, and this method can also extend the sun's life by more than 100 million years.

Of course, it is also possible that in two or three billion years, human beings will no longer have to care about the presence or absence of the sun. In addition to the Sun and countless stars in the universe, there are hundreds of billions in the Milky Way alone. The Sun radiates energy uniformly outward with itself as the center of the sphere, and the Earth receives less than 1/2 billion of the total amount of solar radiation.

If humans could build a large device to enclose the sun and the earth, more energy would be able to be fully utilized. One such device is the Dyson sphere. If a Dyson sphere was built to wrap around the Milky Way, would humanity still care about one less sun?

Perhaps hundreds of millions of years from now humans will be able to build such a Dyson sphere.

The sun will not be destroyed in 5 billion years, and in 5 billion years, human beings will either have rich interstellar navigation technology, or they will be extinct long ago.

Humans can continue humanity in many ways, such as interstellar travel, space-time conversion, changing the sun, changing galaxies, and I believe that with the progress of science and technology, these will all be realized one day.

The destruction of the sun is still very far away from today's human beings, but now the development of human science and technology has made great progress, in terms of space exploration, human beings have realized the close operation of the planet, I believe that one day human beings can leave the solar system before the destruction of the sun, and find a suitable planet to continue human civilization.

If this happens, there is only one way for humanity to go, and that is to escape the solar system.

If human beings want to continue such a civilization, then human beings must create another sun, so that they can continue to continue and continue to live.

Only by escaping the solar system can humans avoid this catastrophe, and this method requires the support of high technology.

If the sun is destroyed after all, we humans will not be able to cope with it, in front of nature, in front of the universe, we are simply a speck of dust, we cannot fight against it at all, and we will not be able to achieve this ability.

Of course you can, because at the time of the destruction of the sun, technology had developed very well and it was possible to leave the solar system and live in other galaxies.

I think that if the sun will always be destroyed, then human beings will not be able to cope with it, because many of our resources and functions need the sun to leave him, and our lives will change a lot.

Humans can't cope with it, because humans are very dependent on the sun, and the energy that the sun has is very huge.

Although it is impossible to cope with the current technology, the development of science and technology in the future is getting better and better, and if the sun is destroyed, human beings can deal with it.

Personally, I feel that human beings are unable to cope with it, because the sun is very important to human beings, and if there is no sun, it will also have an impact on people's lives.

Human beings definitely can't cope with it, the power of nature is very powerful, we can't even avoid floods, how can we avoid such a big situation, and just like the movie The Wandering Earth, we can't do anything.

Human beings should not be able to cope with it, because the reaction of the sun is uncontrollable, and human beings know that human beings are very small compared to the sun, and can even be ignored.

Humanity will definitely not be able to cope with it, because the sun is really, very important to mankind, and if the sun is destroyed, I believe that humanity will also be destroyed.

By the time the sun is destroyed, humans may have created artificial suns or have already settled on other planets.

After the death of the sun, human beings can only go to alien planets, or they can create an artificial sun to replace the sun.

After the earth loses solar radiation, the surface temperature will gradually decrease, all ecological cycles will gradually disappear, different forms of water on the earth will freeze into ice, and life will gradually die out because the temperature is too low.

There are still 5 billion years before the death of the sun, and in the process, human beings must research an "artificial sun" to replace the real sun, or make the alien migration technology mature, and find another home suitable for us in the universe.

In about 5 billion years, the Sun will run out of its hydrogen, expand into a red giant and swallow up Mercury and Venus. Then, if the Earth survives, it will also turn into a flaming fireball due to the huge heat of the sun. Eventually, the red giant will burn out all of its energy and collapse into a white dwarf.

It doesn't turn into a supernova because it's not massive enough and burns out of energy and then throws off its outer material to form a white dwarf.

The mass of the Sun is also not large enough to be a black hole. There are also no black dwarfs in the universe because the universe is not old enough. So it will continue to burn for billions of years until it is swallowed up by a black hole.

A relatively backward human civilization has been discovered in the solar system, and we should not eliminate it, because it is another process of our exploration of the universe. Over the years, human beings have also been constantly searching for other living things in the solar system, and have found some, if human civilization is more backward than ours, we think, should be developed to help it, because it means that the universe, there may be a habitable place, and if the earth's resources are exhausted, people on the earth can move to that place to live, and for humans, there are great benefits.

No, because every civilization has a reason and value for its existence.

Analysis: Will the sun destroy ? Yes.

Will the earth be destroyed with it? Yes.

In another 5 billion years will be the death of the Sun, and the Earth we live in will be swallowed up by the Sun when it becomes an expanding red giant.

Age and lifespan of the sun (relationship between the sun, moon and the earth) The age and lifespan of the sun.

The sun continuously radiates energy into space in the form of electromagnetic waves. This energy is released by the fusion of four hydrogen nuclei into a helium nucleus under high temperature and high pressure conditions. We know that the atomic weight of a hydrogen nucleus is, the atomic weight of a helium nucleus is, and the mass of 4 hydrogen nuclei should be.

When 4 hydrogen nuclei fuse into 1 helium nucleus, a unit of mass is lost, of which, 1 gram of hydrogen nuclei is fused into a helium nucleus. This means that solar energy is produced at the cost of consuming mass, and this mass is converted into solar radiation and no longer belongs to the sun. The sun loses about 4 million tons of mass per second, which is simply too small for a huge solar mass.

In the 5 billion years since the birth of the sun, the sun has consumed only mass, and even in another 5 billion years, it will only consume the mass of the sun. But the question is, no matter how massive the sun is, it is still limited, and how long can the sun last for life? What is the impact on the planet?

The life of the sun starts from the nebula, and finally until the red giant, white dwarf, become the dead remains of the sun, this process will take about 10 billion years, that is to say, another 5 billion years will be the death of the sun, and our human life is rapidly hidden The earth will be swallowed by the sun when it becomes an expanding red giant. If we humans could survive to that time, we would have to fly to other planets to live.
