Ding, the deduction result is below! 】

[Due to the fluctuation of hydrogen in the sun's interior, there is a large fault in the hydrogen inside the sun, causing the sun to begin to age rapidly. 】

[The deduction accuracy rate is 97%!] 】

[The deduction results are reliable!] 】

...

Hearing X Zhinao's answer, Ye Fan was slightly stunned.

Just because of a hydrogen that causes the sun to age rapidly?

"Boss, first of all, explain what the sun relies on to shine and heat."

First of all, at the beginning of the Big Bang, everything was blown up in all directions.

Probably the most basic matter at that time was the hydrogen atom and the hydrogen molecule. After billions of years of accumulation, the early nebula clusters were formed. After 1 million years, the center of the nebula cluster will form a gas-like disk with the highest density and highest temperature, which will increase in temperature under the continuous contraction of its own gravity, and begin to undergo nuclear fusion reaction at about 10 million degrees Celsius, which will form a star.

The Sun is a star, and it is because when it is a nebula, the pressure in the center is too high, which causes nuclear fusion to occur. The occurrence of nuclear fusion leads to a constant increase in temperature. In addition, when nuclear fusion occurs, infrared light and light are also emitted to the outside world. This is the reason why the sun heats up and heats light.

And what about the core?

Most of the interior of the core of the sun is hydrogen (hydrogen accounts for 71%), which is continuously converted into isotopes of C and N through nuclear fusion in its high temperature and high pressure environment, and finally becomes helium, in which the lost mass is converted into energy in the form of electromagnetic spectrum and heat to the outside world, of which about 1/2.2 billion of the energy reaches the earth, which is the main source of light and heat required by life on the earth. Until all H is depleted, its energy will be maintained by nuclear reactions of helium and other heavier elements.

Words that are expressed 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, under the action of gravity, its interior is in a state of high pressure and high temperature, under the state of high temperature and high pressure, 4 hydrogen nuclei fuse into a helium nucleus, during which there will be a mass loss, and the loss of mass is converted into energy and released, by Einstein's mass-energy equation: energy = mass * the square of the speed of light, you can get that fusion will produce great energy, and these energies radiate from the sun in the form of light, The light and heat that form what is now the sun.

The reason for the rapid aging of the sun is that there is a large fault in the core of the sun, and the so-called large fault is actually that the energy cannot keep up, and the engine runs out of oil, and it is because of this that the rapid aging of the sun will occur.

And that's just one of the points.

Another point.

Helium flash.

A helium flash is a sudden start of nuclear fusion in the core of an intermediate-mass star, or on the surface of a white dwarf. It is a naturally occurring explosion of degenerate matter. When the degenerate pressure (which is purely a function of density) exceeds the thermal pressure (which is 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 helium 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 causes the star to release a million times more energy than a normal star very quickly (in a matter of seconds), until the increased temperature gives the thermal pressure a negligible one.

For medium-mass stars, gravity collapse causes the star's core to be very dense, so helium flashes occur when the core is depleted of hydrogen. During contraction, the core temperature becomes warmer and higher until the outer shell expands outward, beginning the phase of a red giant. When the star continues to shrink due to gravity, it eventually becomes a degenerate substance. Degeneracy causes the temperature of the star to rise, and helium combustion begins to close to the end of the explosion.

That's why flares have been frequented lately.

Hear the explanation of X Zhi Brain.

Ye Fan finally understood a little.

In layman's terms, in fact, there is an energy fault inside the sun, not that there is no energy, there is energy, but there is a big fault, the so-called big fault, that is, someone has pulled the gate, and the reason for the brake is that the helium flash.

A helium flash evaporates the hydrogen from the sun's interior.

Hydrogen is the energy source of the sun, and helium flashes eliminate large swaths of hydrogen, which creates a large fault.

Brake application has occurred.

And how helium flash is caused is also because of the complex reasons 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's a helium flash.

Absolutely not for this to happen.

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

Although in terms of the size of the sun, the earth is just a small ant, a small black dot, and it is such a small black dot that has completely caused a huge impact.

The sun was supposed to be able to hold on, but the collapse became more and more severe, causing flares to continue to appear.

The sun is beginning to age rapidly.

"How long will it take for the sun to enter the aging period completely?"

"Boss, according to the current speculation, the flare is only the beginning, at the beginning of our calculations, it is not accurate, there are still thirty years before the sun completely enters the aging period!"

"Once it enters the aging phase, all the surrounding stars will lose their gravitational pull and collide with the sun!"

"Although there are thirty years, during this period, the energy of the flare will become stronger and stronger, and it is expected that humans will only be able to hold out for less than ten years, and will be completely killed by the flare!"

"If a dungeon is built, all human beings will enter the dungeon, and they will stand firm for thirty years, waiting for the sun to enter the aging period, the earth will lose its gravity, expand with it, and the human race will become extinct!"

....

Hearing X Zhi's words, Ye Fan's face sank slightly!

OK.

There's plenty of time left for them.

But the question is, is there really enough time?

At present, although the cause has been found, it is impossible to solve it by relying on current technology.

Not to mention solving it, you can't even get one step closer to the sun.

And also.

Ye Fan has not had a technology that can save everyone until now, according to the plan given by X Zhi Brain.

Dig dungeons.

Build dungeons.

This gives humans more time to breathe.

Live!

"Is there a solution?"

Ye Fan asked.

"Boss, the solution is below!"

"One, build a dungeon, all human beings enter the dungeon and wait for thirty years, and die with the sun!"

"Two, build a large spaceship, migrate!"

"Three, it's time to eat, it's time to drink, and wait for the flare to kill!"

"Fourth, human beings have to withstand flares, but also to endure ice ages, the survival rate of human beings is not high, dungeons are the first choice, build dungeons, and leave the solar system with the earth!"

Take the Earth out of the solar system with you!

Hiss!

Ye Fan gasped, his eyes narrowed slightly.

Reveal a faint glow!
