Darkest Hour

According to calculations, the first wave of the Sun's eruption will reach Jupiter's orbit in less than fifteen minutes. However, because Jupiter is shielding it, Callisto Base still has some Time.

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

As for what happens after that, we can only pray to God to bless Humanity.

While Yue Yuan was speaking, the Sun's eruption, as predicted, erupted with a bang.

There are two mechanisms for Supernova Explosion: one is the explosion of a White Dwarf Star accreting matter from a companion star, and the other is the explosion of a massive Star at the end of its evolution due to its own Gravity collapse, which breaks the balance.

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 generate enough Light Pressure radiation to maintain Gravity balance, and the Star's core will begin to collapse.

This collapse will cause the core temperature and pressure to rise sharply, reaching the conditions for Helium fusion and triggering Helium fusion. The occurrence of Helium fusion allows the Star's core to generate enough radiation pressure again to prevent collapse.

The product of Helium fusion is Carbon, which cools the Star's core slightly, but it is still very high, enough for Helium to continue to fuse. When the Star consumes all the Helium, if its mass is large enough, it will have enough pressure and temperature to continue fusing heavier elements.

For example, Oxygen next, then Neon, Magnesium, and Silicon. The entire process of collapse, stabilization, expansion, and collapse will repeat several times. Each Time, the Star's core will produce heavier elements and generate higher temperatures and pressures, causing them to fuse.

This reaction of continuous production of Heavy Element will cause the Star's Heavy Element to gradually accumulate towards the core, with heavier elements closer to the core. From the outside to the inside, the entire Star undergoes fusion reactions layer by layer, from light to heavy elements, until the final product, Iron or Nickel-56, is produced.

At this point, the fusion reaction stops, and the final Gravity balance is completely broken.

At this Time, under the action of its own strong Gravity, the Star begins to undergo a devastating collapse. The collapse speed of its core can reach 23% of Light Speed. The Battlefield with Gravity and Electromagnetic Force as the protagonists is staged here, and then the Supernova Explosion begins.

In addition to the initial light and heat, the vast majority of matter is accelerated to one-tenth of Light Speed and ejected outward. The final remaining part will have different endings depending on the mass.

If it does not exceed the Chandrasekhar Limit, it will form a White Dwarf Star. If it exceeds the Chandrasekhar Limit but does not exceed the Oppenheimer Limit, it will become a Neutron Star. As for exceeding the Oppenheimer Limit, there is no doubt that it will become a Black Hole.

But this second mechanism requires at least eight times the mass of the Sun to occur.

The Southern Gate Two Trinary Star System, Star A has a mass of only 1.1 times that of the Sun, Star B is 0.907 times, and Proxima Centauri is an even smaller Red Dwarf Star, so they, like the Sun, do not belong to these two mechanisms.

They belong to a third type that has never appeared: a strike by a highly advanced civilization.

As we all know, the larger the mass of a Star when a Supernova explodes, the greater its power. Therefore, the eruption power of the Sun and the Centaurus Trinary Star System must be much smaller than a normal Supernova Explosion.

The range of a normal Supernova Explosion is extremely wide, and the powerful radiation and shock waves it releases can affect a range of 160 Light-year. If there are Life Planets within this range, the energy released by the Supernova is enough to blow away the atmosphere of the Planet and kill all living things on the Planet.

Of course, the killing power of this range refers to super-massive Stars and organisms exposed on the Planet's surface.

The Sun is much smaller than a normal exploding Supernova, but even though it is small, it is still a Supernova Explosion, far beyond what current Human Civilization technology can resist.

After all, it's too close, almost point-blank.

Moreover, what exactly caused the Sun to explode is still unknown.

At this moment, the Sun, following the Alpha Centauri Three Stars, became the fourth Star to illuminate the entire Milky Way Galaxy.

The violent Gamma Ray radiated outward from the Sun as the center. The gentle Sun transformed into the God of Death, launching an indiscriminate attack on the entire Solar System.

The Xihe Probe instantly melted, and Mercury, which was closest, only lasted a few more seconds before completely disintegrating and turning into cosmic dust.

In these few seconds, the Sun roared and released the super energy that would have taken billions of years to release, rushing out and pouring over a distance of one Astronomical Unit onto the Planets.

Venus lasted a few dozen more seconds before following in Mercury's footsteps.

Then came Earth.

The ocean of light swept over, and the side of the world facing the Sun instantly turned white, an ocean of light. The surface vegetation instantly caught fire and turned into ashes, and the towering mountains instantly turned into Magma, even sublimating.

Sublimation, not some spiritual sublimation, but physical sublimation, the change from solid to gaseous is called sublimation.

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

The dark side also turned into day, and the temperature rose rapidly.

As the Earth rotated, the other side, still struggling to survive, was not spared. The great projects on the planet became tofu dregs in the face of this force.

Han Hai became Han Hai again, and then transformed into a sea of magma.

That magnificent Orbital Mass Accelerator, the pride of Humanity, was instantly melted into molten iron, re-integrating with the earth.

Under the ravages of light and heat, the earth cracked, ground fire erupted, tectonic plates disintegrated, the Earth began to split, and merged into the ocean of light.

Together with it, the pinnacle of Humanity's space station, Heavenly Palace, also merged into the light.

Next, it was the Moon, Guanghan Palace. They also couldn't withstand the infinite energy from the Sun, and completely fell apart, disintegrating.

Mars, with its more distant orbit, held on for a few more minutes, but inevitably followed in the footsteps of Mercury, Venus, and Earth, all becoming part of the sunlight.

Han Hai, Orbital Mass Accelerator, Heavenly Palace, Xihe, Guanghan Palace, Yinghuo, Artemis, Apollo, Zeus...

Each name that Humanity was proud of, each spiritual sustenance that Humanity took pride in, each pinnacle of Human Civilization's technological creations, each Great Project of Humanity, all seemed so small and fragile in the face of the Sun's Rage.

Greatness seemed to become a mockery to highlight the smallness and fragility.

All was silent.

The betrayals, the tender affections, the heroic spirit, the love and hatred that once existed there, all turned into light. The prayers to Gods, the spurning of Demons, all turned into light.

This was the Darkest Hour in Human history.

The darkness of destruction swept through the Asteroid Belt, penetrated the massive Jupiter, shattered all the strong souls, and was deeply imprinted in the hearts of that group of survivors.

This was the brand of Humanity's pain and sorrow, a merciless blow from the Unknown Universe to Humanity, which had just taken its first step out of the cradle.

It shattered all of Humanity's beautiful fantasies about this Unknown Universe.

Ah! Please invest, let's have a wave, let's have a hundred investments.
