Voyage of the Stars

According to calculations, the first wave of the solar explosion will reach Jupiter's orbit in less than fifteen minutes, but because Jupiter blocked the impact with its body, the Callisto base still has time.

Callisto's orbital period is 16.7 days, and it has just begun to slip behind Jupiter, so Jupiter can still provide it with protection for at least 6 to 7 days.

As for what happens next, we can only pray to God to bless mankind.

While Yue Yuan was speaking, the sun exploded as predicted.

There are two mechanisms for supernova explosions. One is that a white dwarf star accretes material from a companion star and explodes. The second is that a massive star suffers its own gravitational collapse at the end of its evolution, and then the balance is broken and explodes.

The second type is the most common in the universe. When the hydrogen in the star's core is burned out, the star can no longer produce enough light pressure radiation to maintain gravitational balance. At this time, the star's core will begin to collapse.

This collapse will cause the core temperature and pressure to soar sharply, reaching helium fusion conditions and triggering helium fusion. The occurrence of helium fusion will cause the core of the star to once again generate enough radiation pressure to prevent collapse.

The product of helium fusion is carbon, which cools the star's core slightly, but is still very high enough for helium to continue fusion. After a star consumes helium, if it is massive enough, it will have enough pressure and temperature to continue fusion of heavier elements.

For example, next comes oxygen, then neon, magnesium, and silicon. The entire process of collapse, stabilization, expansion, and collapse will be repeated several times. Each time, heavier elements will be produced in the core of the star, and higher temperatures and pressures will be generated. It undergoes fusion.

This continuous reaction of heavy elements will cause the heavy elements of the star to gradually accumulate toward the core, and the elements closer to the core will become heavier. From the outside to the inside, elements move from light to heavy, and fusion reactions occur layer by layer throughout the star until the final product is produced, iron or nickel-56.

At this point, the fusion reaction stops, and the gravitational balance is finally completely broken.

At this time, under the influence of its own strong gravity, the star begins to undergo a devastating collapse. Its core collapse speed can reach 23% of the speed of light. The battlefield where gravity and electromagnetic force are the protagonists is staged here, and the supernova explosion begins.

Except for the initial light and heat, most of the matter is accelerated to one-tenth the speed of light and thrown outward. The remaining parts will have different endings depending on their quality.

If it does not exceed the Chandrasekhar limit, it will form a white dwarf. If it exceeds the Chandrasekhar limit but does not exceed the Oppenheimer limit, it becomes a neutron star. As for what exceeds the Oppenheimer limit, there is no doubt that it will become a black hole.

But this second mechanism requires at least eight solar masses to occur.

In the Nanmen triple star system, the mass of star A is only 1.1 times that of the sun, star B is 0.907 times that of the sun, and Proxima Centauri is a small red dwarf star, so they do not belong to these two mechanisms like the sun.

They belong to a third category that has never appeared: advanced civilization strikes.

As we all know, the more massive a star is, the more powerful it will be when it explodes as a supernova. Therefore, the explosion power of the sun and the Centauri triple star system must be much smaller than normal supernova explosions.

A normal supernova explosion has a very wide range. The powerful radiation and shock waves it releases can affect a range of 160 light years. If there is a planet with life within this range, the energy released by the super information is enough to blow away the atmosphere of the planet. , killing all living things on the planet.

Of course, this range of lethality refers to supermassive stars and organisms exposed on the surface of planets.

The sun is much smaller than normal supernova explosions, but although it is small, it is still a supernova explosion, which is far beyond what human technology can resist today.

After all, it was too close, almost touching the face.

Moreover, it is still unknown what actually caused the sun to explode.

At this moment, the sun became the fourth star to illuminate the entire galaxy after the Centauri.

The violent gamma rays first radiated outward with the sun as the center. The gentle sun turned into the god of death and launched an indiscriminate attack on the entire solar system.

The Xihe probe melted instantly, and the closest Mercury didn't last more than a few seconds before it completely fell apart and turned into cosmic dust.

In these few seconds, the sun roared and released super-powerful energy that originally took tens of billions of years to release, rushing out across a distance of one astronomical unit and pouring on each planet.

Venus persisted for dozens of seconds longer and followed in the footsteps of Mercury.

Then comes the Earth.

The ocean of light washed past, and the world on the side facing the sun instantly turned white, a sea of ​​light. The surface vegetation instantly caught fire and turned into fly ash, and the towering mountains instantly turned into magma, and even sublimated.

Sublimation is not spiritual sublimation, but physical sublimation. The change from solid state to gaseous state is called sublimation.

The earth's atmosphere was blown away in an instant, the seawater boiled and evaporated, and the vast continent turned into soup.

The night side also turned into day and quickly heated up.

As the earth rotates, the other side that is still surviving is not immune to the disaster. All the great projects on the planet turned into rubbish in the face of this force.

The vast sea turned into a vast sea again, and then transformed into a magma sea.

The magnificent orbital mass accelerator that mankind is proud of was instantly melted into molten iron and integrated with the earth again.

Under the devastation of light and heat, the earth cracked, fire spewed out, the plates fell apart, and the earth began to crack and merge into the ocean of light.

Also integrated into the light is the pinnacle of the human space station, the Tiangong.

Next, there is the moon, Guanghan Palace. They could not withstand the infinite energy from the sun, and completely fell apart and fell apart.

The orbit of Mars is farther away, and it lasted for a few more minutes, but it inevitably followed the footsteps of water, metal, and earth, and became part of the sun's rays at the same time.

Hanhai, Orbital Mass Accelerator, Tiangong, Xihe, Guanghan Palace, Yinghuo, Artemis, Apollo, Zeus.

Every name that mankind is proud of, every spiritual sustenance that mankind is proud of, every scientific and technological creation at the pinnacle of human civilization, every great human project, all appear so small and fragile in the face of the wrath of the sun.

Greatness seems to be a mockery to set off smallness and fragility.

Everything is quiet.

The intrigues, tenderness, heroic spirit, love and hatred that once existed there have all turned into light. The prayers to the gods and the rejection of the devil there all turned into light.

This is the darkest moment in human history.

The darkness of destruction rushed through the asteroid belt and passed through the huge Jupiter, shattering all strong souls and leaving a deep mark on the hearts of those survivors.

This is the mark of human injury and pain. It is a ruthless blow from the unknown universe to human beings who have just stepped out of the cradle.

It shattered all mankind’s beautiful illusions about this unknown universe.

ah! I beg you for investment. Come and invest and kill hundreds of people.
