Through the spaceship's electronic camera, Xiao Wu witnessed the complete destruction of Earth.
Just before that, Earth's core had undergone a super-explosion. This explosion tore Earth into pieces, and the enormous energy burst accelerated the Moon to 137 km/s. Calculations indicated that the Moon would be ejected from the Solar System and become a rogue planet.
Simultaneously, the entire Solar System would transform into a cosmic battlefield. It was predicted that, in the next few million years, all planets in the Solar System would suffer continuous bombardment from Earth's fragments.
Countless observational data streamed into Xiao Wu's mind. He sighed, accelerated the spaceship to its maximum speed, and headed towards the Solar System.
In fact, 10 years before the disaster, Xiao Wu, humanity's most outstanding scientist—holding doctorates in more than twenty fields, including theoretical physics, high-energy physics, astrophysics, mechanical engineering, astronomy, chemistry, and computer science, and having received over 20 Nobel Prizes—had noticed these signs. Sadly, Xiao Wu's warnings were ignored and mercilessly ridiculed by human society. Everyone thought he had gone mad. One agitated scientist even shouted into the media's cameras: "I don't know what evidence Xiao Wu used to reach that conclusion, was it a dream last night? Earth will be destroyed? That's ridiculous, even kindergarteners know Earth will always be safe!"
Xiao Wu smiled bitterly and thought, "Even if human society had accepted the warning, with the current level of science and technology, there was no way to prevent the destruction. Instead of letting them live in despair, it's better to let them experience their final moments of happiness."
Therefore, Xiao Wu left the scientific community, accumulated a vast fortune in two years, becoming the world's richest person, and began his plan.
Relying on scientific knowledge that surpassed the rest of the world by at least 20 years, Xiao Wu spent eight years creating humanity's first official spaceship, assembling it completely in Earth's orbit. Afterward, Xiao Wu remotely controlled, using equipment he himself created, the separation of his soul, sending it to the spaceship's server and merging it. Then, without hesitation, he accelerated, escaping Earth's gravitational pull and heading into outer space.
Xiao Wu proved that the human spirit, or soul, could exist eternally under special conditions. Furthermore, discarding the body and merging the spirit with a computer had other advantages, such as saving a huge amount of space for water, food, and life support systems.
This is the entire sequence of events.
"It seems I am the last remaining human in this universe." The situation before him caused Xiao Wu to pause for a moment, "No, perhaps in a purely spiritual state, I am no longer considered a human."
"However, possessing immense computational power, along with the feeling of boundless energy and lifespan, is wonderful." Xiao Wu meticulously felt every detail of his new form, exclaiming in admiration.
Xiao Wu's new body is 30 meters long, 20 meters wide, and about 5 meters high. The spacecraft is divided into several areas: a raw material storage room, a material storage room, an equipment storage room, a laboratory, a manufacturing equipment storage room, a manufacturing material storage room, a control server room, and a repair tunnel. An exquisitely crafted robot is responsible for the daily maintenance of the entire spacecraft.
In the vast expanse of space, the small spacecraft is moving forward at a dizzying speed, approximately 33 km/s. But even at this speed, it will still take about 200 days to reach the largest star – Jupiter.
That's right, the first destination Xiao Wu is heading to is Jupiter. Because there is an almost inexhaustible source of nuclear fuel there. Although for various reasons, Xiao Wu chose chemical fuel as the engine for his spacecraft, after researching and inventing a method to control thermonuclear reactions, he will not hesitate to upgrade the propulsion system to a nuclear engine.
Through the telescope, the direction of Earth has turned into a large bright spot. Xiao Wu knows that this is because the seawater on Earth is evaporating under the sunlight. These substances will gradually peel off and scatter in the vast universe, a process that could take millions of years.
Countless fragments from the Earth's explosion will scatter: some will rush towards the Sun, some will fly into space, and the rest will collide, slowly merge, and eventually form a new planet. Of course, its size will be much smaller than before.
"Haizz." Xiao Wu sighed silently in his heart. Witnessing his homeland buried in ashes, remembering the 7 billion people who died instantly, Xiao Wu's heart is heavy.
"It's a pity that I don't have the ability to save them... However, there is something strange about this explosion... It's as if some kind of bizarre external force is controlling it." Xiao Wu uses his enormous computational ability to perform some logical inferences, but obtains no results and has to give up this thought.
"The vast universe, where is home?" Xiao Wu feels his heart sink. But immediately, he tells himself: "With my current abilities, the speed of scientific and technological development of an individual can be comparable to, or even surpass, the entire human race. Moreover, this speed can increase even faster with new materials and the creation of more powerful computers. So, let's start exploring the endless wonders of the universe!"
Thinking of this, Xiao Wu's heart is filled with excitement again.
At this moment, from the distance, in the direction of Earth, a bright spot attracts his attention.
The telescope attached to the outside of the spacecraft immediately moves to the appropriate angle, pointing towards the bright spot.
This bright spot is very large, and the current distance is not too far. Therefore, Xiao Wu can easily determine the size of this celestial body.
"It's the Moon... No!" An ominous premonition suddenly flashed in Xiao Wu's mind. He immediately inputs the parameters of the operating orbit, size, speed, and orbit of the Solar System into a formula. His superior computational ability quickly produces the result.
"How could this be such a coincidence? How could this be such a coincidence? How could this be such a coincidence? At the current speed, the Moon should have passed Jupiter and flown into space! How could the orbit be so coincidentally aligned?"
"Oh my god... Is God playing a trick on me? Isn't this trying to kill me?" Xiao Wu stared wide-eyed at the results, cursing inwardly.
"Could it be that I really have to witness the biggest collision event in the history of the Solar System?"
Xiao Wu cried out helplessly.
The calculation results clearly showed that, at the current speed, in about 50 days, the Moon would collide head-on with Jupiter, the largest planet in the Solar System.
A direct collision between two celestial bodies of planetary size is very rare. The most likely scenario is that Jupiter would capture the Moon as its satellite, then its orbit would gradually shrink. At a certain distance, the Moon would be torn into many small pieces and successively crash into Jupiter.
The collision process could last for tens of thousands of years. But the Moon's orbit was coincidentally aligned, directly leading to a head-on collision.
"Our level of science and technology and equipment is still in its infancy, how can we avoid such a terrifying cosmic collision event?" Xiao Wu lamented.
Seventy million years ago, the asteroid that caused the extinction of the dinosaurs was only about 10km in diameter. And the diameter of the Moon? Over 3,400km!
The diameter of Jupiter is about 140,000km! Previously, the fragments of Comet Shoemaker-Levy 9 collided with Jupiter, each fragment only about 2km in diameter, but the collision released a total energy equivalent to more than 40 trillion tons of TNT! The speed of the fragments of Comet Shoemaker-Levy 9 was 210,000 km/h, while the current speed of the Moon is over 400,000 km/h.
How much energy would the collision release? Xiao Wu dared not calculate. But he was certain that the matter ejected from the impact point, along with the emitted radiation, would sweep away the entire Solar System. Small asteroids would be blown away, the newly formed asteroid belt would be completely destroyed, and even a part of it could hit the Sun. If the fragments are too large, they could break through the Sun's convection layer, causing a large mass loss, causing the Sun to weaken rapidly.
In other words, this collision has the potential to destroy the entire Solar System. Even if it doesn't destroy it, the Solar System will become hell.
Xiao Wu increasingly suspected that this destruction of the Earth was the result of a silent calculation by an outside force. Otherwise, things wouldn't be such a coincidence.
"Damn it, first, we must find a way to get through the most intense collision phase. If directly enveloped by radiation, with our current technology, the entire spacecraft will be instantly dissolved, even billions of kilometers away is useless."
Xiao Wu was secretly terrified, and at the same time, his enormous computing power began to operate at full capacity.
This is a computer center designed and built by Xiao Wu, whose scientific and technological level surpasses humanity by at least 20 years. Its computing power is almost equivalent to that of the most powerful supercomputer on Earth, but its energy consumption is only one ten-thousandth.
In the blink of an eye, countless orbital parameters, speed parameters, and other types of parameters were inputted for calculation. Countless indicator lights began to flash continuously. It took Xiao Wu a full half hour to recover his composure.
"This is the only way... Um, there's roughly a 50% chance of safely passing through the initial phase of the strongest impact, but my energy reserves are insufficient." Xiao Wu silently lamented.
"Change the trajectory, head towards Mars. It is expected to reach Mars' orbit in 20 days, then maintain a position hiding behind Mars, using it as a shield, perhaps we can overcome this calamity. After that... Jupiter is unreachable, so let's go to Saturn. Saturn's Titan satellite is not bad, it reserves a large amount of methane, which can be used as fuel. It's just that the oxidizer is still a headache, without an oxidizer, methane cannot burn. Whatever, let's take it one step at a time, I'm almost dead anyway."
