Chapter 714： : Leave the solar system! Be sure!

Ding, the deduction results are as follows! 】

[Because of the fluctuation of hydrogen in the sun, a large fault occurs in the hydrogen inside the sun, causing the sun to begin to age rapidly. 】

[The accuracy of deduction is 97%! 】

[The results of the deduction are reliable! 】

...

Hearing X Zhinao's answer, Ye Fan froze slightly.

Just because one hydrogen caused the sun to age rapidly?

"Boss, first explain what the sun depends on to glow and heat."

First, at the beginning of the Big Bang, all the material was exploded around.

Probably the most basic substances at that time were hydrogen atoms and hydrogen molecules. After billions of years of accumulation, the early nebula cluster formed. After a period of 1 million years, the nebula will form a gas disk with the highest density and the highest temperature in the center. Under the continuous contraction of its own gravity, the temperature of the disk rises not shortly, at about 10 million degrees Celsius Nuclear fusion began to occur, which formed stars.

The sun is a star. It is because the pressure in the center is too large when it is a nebula cluster, which causes nuclear fusion. The occurrence of nuclear fusion has led to a continuous increase in temperature. In addition, when nuclear fusion occurs, infrared rays and light are also broadcast. This is why the sun generates heat and heat.

And the core?

Most of the sun's core is hydrogen (hydrogen accounts for 71%). Under its high temperature and high pressure environment, it is continuously converted into isotopes of c and n through nuclear fusion, and finally into helium, where the lost mass is converted into energy. It is emitted to the outside world in the form of electromagnetic spectrum and heat. Among them, about one-billionth of the energy reaches the earth, which is the main source of light and heat required by the creatures on the earth. Until all h is exhausted, the nuclear reaction of helium and other heavier elements will maintain its energy.

Express words in professional language.

The energy of the sun mainly comes from the internal nuclear fusion. The main components of the sun are hydrogen and helium. Due to the huge mass of the sun, the interior of the sun is under high pressure and high temperature under the action of gravity. The fusion of 4 hydrogen atoms under high temperature and high pressure It becomes a helium nucleus, during which there will be a mass loss. The lost mass is converted into energy and released by Einstein's mass-energy equation: energy = mass * square of the speed of light. It can be obtained that fusion will produce great energy. These energy It radiates from the sun in the form of light, forming the current sun's light and heat.

The reason for the rapid aging of the sun is that there is a large fault in the solar core hydrogen. The so-called large fault is actually that the energy cannot keep up and the engine is out of oil. It is because of this that the rapid aging of the sun occurs.

This is just one point.

also.

Helium flash.

Helium flash is the fusion of helium that suddenly accumulates on the surface of a medium-mass star or white dwarf star. It is a natural explosion caused by degenerate matter. When degenerate pressure (purely a function of density) exceeds thermal pressure (proportional to density and temperature), the correlation between total pressure and temperature is weak.

The so-called helium flash, once the temperature reaches 100 million to 200 million k, and the nuclear fusion of the helium element begins, the temperature will increase rapidly, which will further increase the rate of helium fusion and the reaction area, but will not increase the pressure. So the core will not expand steadily (and cool). The thermal runaway reaction makes the energy released by the star quickly (in a few seconds) more than a million times that of a normal star, until the increased temperature makes the thermal pressure once again dominate, and degeneracy pressure can be ignored.

For a medium-mass star, the collapse of gravity causes the star's core density to be very high, so helium flashes occur when the core's hydrogen is exhausted. During the contraction, the core temperature becomes higher and higher until the outer shell expands outward, starting the stage of the red giant. When the star continues to shrink due to gravity, it eventually becomes degenerate matter. The degeneracy caused the star's temperature to rise, and helium burning began to approach the end of the explosion.

This is why flares frequently appear recently.

Hear x Zhinao's explanation.

Ye Fan finally understood a little.

To put it in plain terms, in fact, there is an energy fault inside the sun, not without energy. There is energy, but there is a large fault. The so-called large fault is caused by someone pulling the brake , This is the flash of helium.

The helium flash evaporates the hydrogen inside the sun.

Hydrogen is the energy source of the sun, and helium flashes eliminate large pieces of hydrogen, which creates large faults.

There was a behavior of stepping on the brakes.

And how the helium flash is caused is also due to the complicated reason inside the sun.

The act of stepping on the brakes caused the sun, which was originally an energy body, to begin to collapse internally.

If it is a helium flash.

This will definitely not happen.

But what if a helium flash of the size of an earth appears?

Although in terms of the volume of the sun, the earth is a small ant, a small black spot, and such a small black spot has completely caused a huge impact.

The sun should have been able to persevere, but this kind of collapse has become more and more serious, leading to the continuous emergence of flares.

The sun began to age rapidly.

"How long will it take to push the sun, and it will completely enter the aging period?"

"Boss, according to the current speculation, the flare is just the beginning. Our calculation at the beginning was not accurate. At present, it is still thirty years before the sun completely enters the aging period!"

"Once entering the aging period, all stars around will lose gravity and collide with the sun!"

"Although there are thirty years, during this period, the energy of flares will become stronger and stronger. It is expected that humans can only persist for less than ten years and will be completely killed by flares!"

"If you build an underground city, all human beings will enter the underground city for 30 years. After the sun enters its ageing process, the earth loses its gravity, expands with it, and humans become extinct!"

....

Hearing X Zhinao, Ye Fan's face sank slightly!

Fortunately.

There is still plenty of time left for them.

But the question is, is there really enough time?

Although the cause has been found, it cannot be solved by relying on current technology.

Not to mention the solution, you can't get closer to the sun.

and also.

Until now, Ye Fan has no technology that can save everyone, according to the plan given by X Zhinao.

Dig into the underground city.

Build an underground city.

This gives humans more time to breathe.

Go live!

"No solution!"

Ye Fan asked ~ www.novelhall.com ~ boss, the solution is as follows! "

"One, build an underground city, and all humans enter the underground city and wait for thirty years, and they will die together with the sun!"

"Second, build a large spaceship and migrate!"

"Three, eat and drink, drink and wait for the flare to kill!"

"Fourth, humans have to withstand flares, but also withstand the ice age. The survival rate of humans is not high. The underground city is the first choice. Construct the underground city and leave the solar system with the earth!"

Take the earth and leave the solar system together!

hiss!

Ye Fan took a cold breath and narrowed his eyes slightly.

Reveal a faint light!
