The sun still has 5 billion years of life, why is it that humans are only a billion years old?

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.

The sun is a celestial body and has a long lifespan. Human beings need to rely on various resources for survival, but many resources are non-renewable, so human beings have a short lifespan.

Because the life span of the sun must be longer than that of the earth, without the sun, the earth would no longer exist, and the life span of human beings is not necessarily the same as that of the earth.

The sun's glow and heat are not caused by nuclear fusion, but by gravitational focusing. It was the most convincing Copernican revolution and a major discovery that shook the scientific community. This is true of all shining stars.

Please see the first issue of "Scientist" after 2021 "The Nature of the Sun - The Principle of Sun Luminescence and Heat", which has a detailed explanation and argument, which is undoubtedly true.

The theory of the origin of the solar system says: At first, there was originally a nebula, followed by a nebula**, the sun was born, and then other fragments formed the earth, Venus and other planets, and when everything was stabilized, a complete solar system was formed. The sun sits in the middle, bringing heat to the planet, and the earth is very fortunate to be in the most privileged environment, giving birth to countless lives, but everything in the world will have an end, and even the planet will have a day when it will perish.

Scientists have calculated that the life span of the sun is only 10 billion years, and now it has gone half of the time, many people will think that life on earth and the sun coexist, so life on earth should be able to survive for about 5 billion years, but this is not the case, life on earth may die out in about 1 billion years, unless human beings can fly out of the solar system and go to other galaxies to survive, otherwise everything will come to naught, what is going on?

As we all know, the reason why the sun emits heat when it is buried is because of the chemical reaction that takes place inside it, which we call "nuclear fusion". Over time, the heat inside the sun will get higher and higher, the sun will emit more heat, and the more heat the sun emits, the higher the heat absorbed by the earth, and the surface temperature will rise. Scientists say that in 1 billion years, the sun will have 10% more heat than it does now, and although 10% is a very small number, it is a very scary number for a planet.

It is well known that the surface temperature of Venus is more than 400 degrees Celsius, and in addition to its proximity to the Sun, it also depends on its own greenhouse effect, and the Earth may become another Venus in 1 billion years.

Scientists say that the Earth's surface temperature may reach more than 60 degrees Celsius in 1 billion years, which means that the Earth's liquid water will gradually dry up, and all creatures that like cold will die, and it is difficult for humans to live in such a hot environment. And with the passage of time, the radiation value of the sun will be higher and higher, and the temperature of the earth will continue to rise at that time, if the sun has a flare at this time, it is very likely that all the equipment on the earth will fail, and the old sun will become very unstable, and it is possible that there will be a solar flare every once in a while, or there will be a hydrogen flash phenomenon, which is a fatal blow to the earth, and the earth may lose its atmosphere and become a "dead planet".

In 1 billion years, the Earth will become very desolate and terrifying, from a blue planet to a fiery red planet, where all life will be completely wiped out, and then reduced to a "very cranky" planet, and after that, it will be difficult for life to appear on Earth.

Even if all the hydrogen on the sun is burned, there will be other thermonuclear reactions that will continue to take place, so the sun can continue to emit its tremendous light and heat! Combustion is a figurative statement, which is essentially a continuous nuclear fusion reaction, so it can continue to react for hundreds of years. Combustion, this word means that you don't understand that combustion belongs to chemistry, and the sun is in nuclear physics - fusion.

Of course, fusion only happens in the center. Why does it last for so long, that is, the stars are huge, but the sun is the medium size of the stars, and the larger the star, the shorter the lifespan.

The sun is a higher energy level transformation, and the force that supports this transformation is the collapse of space, and the collapse of space is not instantaneous, but it must be opposite to the matter in the collapsed space, and finally form a black hole, so you see that the process of burning the sun is the process of space and matter confronting each other, so its time and energy are cosmic.

This is related to the mass of hydrogen consumed per unit time of the solar nuclear reaction. If the current rate of consumption is maintained, it will be enough for billions of years. If it is accelerated, it will be shortened, and if it is not, it will be extended!

If solar energy gets hydrogen**, it can also be extended! Hydrogen is just the environment, the problem is the state of the central tritium, it must be balanced, and then a subtraction is formed deuterium, deuterium and deuterium are completely balanced, the whole quantum entanglement Ha, and then release excess heat, there is no fusion.

To put it another way, the sun is eternal. Light moves at the speed of light, and people can't feel its impact, so the mass of light is very small. Because the mass of light is small, the mass that the sun loses by radiating outward each year may be equivalent to a small stone.

But the sun absorbs a lot of things every year, such as meteorites, or comet fragments. The quality gained is much greater than the quality lost. So the sun is eternal!

The internal temperature of the sun is 15 million degrees, what is the pressure? Matter won't be solid? At least the super-density state, perhaps smaller than the known microscopic quarks, but one thing it is stable, and a nuclear explosion does not occur until it reaches about 10,000 degrees.

Because in 1 billion years, the heat emitted by the sun will be very large, and it will be enough to destroy the whole world.

Because in 10 years, the sun will get hotter and hotter, which means that many creatures on the earth will not be able to survive properly.

This is just a superstitious statement, in fact, it is not like this at all, and there is no evidence, so don't believe it.

We know that the sun is about 100 million kilometers away from the earth, is a huge plasma fireball, with a diameter of 1.39 million kilometers, its volume is unusually large, can accommodate 1.3 million earths, and the mass occupies almost 100% of the entire solar system, and because of this, all celestial bodies in the solar system revolve around the sun, scientists calculate through the law of gravitation that the mass of the sun is about 10 kg, equivalent to 200 billion trillion tons.

As the only star in the solar system, because of the huge mass, the internal temperature has reached 15 million degrees Celsius, and the pressure is 300 billion atmospheres, in this ultra-high temperature and ultra-high pressure environment, the core is undergoing violent nuclear fusion reactions all the time, about 600 million tons of hydrogen will fuse into 100 million tons of helium every second, of which 4 million tons of matter are directly converted into energy release, and it is these energies that bring light and heat to the earth.

Nowadays, astronomers speculate through the evolution model of stars that the sun was born about 4.6 billion years ago, a huge molecular cloud collapsed, in the initial period of the original solar system position was just a cold nebula floating in the universe, but one day it was disturbed by some kind of disturbance (supernova explosion), so that the nebula appeared a super-density region, this super-dense region began to collapse under the action of gravity, the nebula gathered more and more, and finally reached the conditions of nuclear fusion, thus forming the sun.

According to the evolution model of the star, we not only know how the sun was born, but also know its lifespan, because the sun is a yellow dwarf, it contains hydrogen elements that can be burned for nearly 10 billion years, and the sun has burned for 4.6 billion years, which means that the sun only has a life span of nearly 5 billion years, and after about 5 billion years, the fuel will run out and go to the end of the star's death, entering the age of red giants. During the red giant period, because there is less and less fuel, the energy generated by the core will not be enough to maintain hydrostatic equilibrium, and the volume will expand to 200 times, and the earth will be directly engulfed by the red giant.

So is there still 5 billion years left for humans to survive, which is not the case!

We know that in the core of the sun, a large amount of hydrogen is gradually converted into helium nuclei, which will lead to an increase in the density of the core and an increase in pressure, so that the hydrogen element burns more violently, then the temperature of the sun will be higher and higher, scientists have calculated that the luminosity of the sun will increase to about 10% in a billion years, and this 10% is enough to make the oceans and lakes on the earth evaporate and disappear, cause forest fires on the surface, and destroy life! The earth is no longer a habitable zone in the solar system, and the habitable zone will also move outward, so there are only 1 billion years left for mankind

But then again, 1 billion years is too long for our lifespan, and with today's scientific development, human footprints may have already spread to all corners of the solar system, and they will be able to travel to other planets, and even have rushed out of the solar system to the depths of the universe, so we will have enough time to escape from the earth for a billion years from now!
