Humanity is missing, luckily I have billions of clones.

Chapter 170 Gravitational Boundary
Following Li Qingsong's order, more than 3000 million various spacecraft divided into six groups either ignited themselves to propel themselves forward, or boarded the aerospace mothership and began to accelerate at the same time with the help of the aerospace mothership's power.

Six fleets, facing six stars and six directions respectively.

Aside from the actual Migration Fleet, none of the other five fleets had a single clone. The entire fleet operated completely automatically.

They would follow Li Qingsong's pre-set trajectory, flying and accelerating automatically. Once they completed their acceleration and entered the inertial navigation state, all intelligent control components would self-destruct, and all the ships in the fleet would transform into completely devoid of intelligence, continuing their flight in the inertial navigation state.

Under the illumination of countless engines, for a moment, the numerous stars throughout the Jupiter system seemed to converge into a curtain of light, illuminating the entire Jupiter system.

But as the fleet accelerated and moved away, the light curtain gradually dimmed and eventually split into six parts heading in six different directions.

The huge Jupiter gradually shrank and eventually turned into a shining star, merging into the vast sea of stars.

The clone containing Li Qingsong's consciousness stood in front of the huge spaceship window, quietly watching the galaxy spinning outside the window.

At this moment, most of Li Qingsong's forces were already on the move.

But inside this solar system, Li Qingsong still left some things behind.

They are some technological creations hidden in extremely remote corners far away from the ecliptic plane, as well as some clones in hibernation.

They may be telescopes, spy satellites, bases, etc.

Under the control of intelligent programs and the energy supply of low-power long-duration fusion reactors, they are as inconspicuous as dust, running quietly in the corner where no one pays attention.

Once any abnormal changes are detected, such as a bright tail flame observed in a certain direction, or an external force entering the solar system, the clones will be awakened.

With the communication technology that Li Qingsong currently possesses, it is not yet possible to communicate at light-year levels.

Electromagnetic wave communications attenuate too much, and are subject to too much interference when propagating through interstellar space. The information they carry simply cannot travel very far.

It can't even travel one light year, let alone directly from the solar system to another star.

This leads to a result that once Li Qingsong is too far away from the solar system, he will completely lose contact with the solar system.

Even if Li Qingsong left behind more technological creations in the solar system, they would be useless.

But this was only the normal case. Obviously, Li Qingsong's existence was not ordinary.

The connection between his original body and the clone does not seem to weaken as the distance increases - of course, this is just a speculation based on some experimental data at this stage, but Li Qingsong believes that this possibility is very high.

In this way, no matter how far away you are from the solar system, you can still obtain some information about the interior of the solar system by acting as a clone of an "observer".

If the intelligent machine disaster really came to the solar system in the future, he would be able to get the news at the first time and would not be completely ignorant of the enemy's movements.

At this moment, there are about 500 observers sleeping in various corners of the solar system, and about various equipment and bases left by Li Qingsong are operating silently in concealment.

After a long time, he withdrew his gaze from the solar system and looked in another direction.

There is also a bright star there.

That is the destination of this voyage.

In the second month after the migration began, the huge migration fleet crossed the orbit of Saturn, and in the fifth month it crossed the orbit of Uranus, then Neptune, and then Pluto.

In the 10th month after the migration, the migration fleet crossed the orbit of Rosene.

At this moment, the migrating fleet is about 151 billion kilometers away from the sun.

At the initial speed of 15 kilometers per second, the migrating fleet has been accelerating at an acceleration of 0.04 meters per square second for 11 months, and its speed has now reached 1140 kilometers per second.

Through a long period of acceleration, Li Qingsong achieved an extremely high speed that he had never reached before.

At this moment, the fleet crossed the orbit of Luoshen at such an ultra-high speed and flew towards the vast deep space where not only Li Qingsong, but the entire human civilization had never reached before, and at most only unmanned probes had been launched there.

This place farther away from the sun seems to be no different from the inner solar system. It is just as empty, vast and deep.

It seems that no matter how long the voyage lasts, the scenery seen from the outside world does not change much.

Time passed quietly in this situation, and gradually, the fleet arrived at a place about 950 billion kilometers away from the sun.

The clone containing Li Qingsong's consciousness once again turned its gaze to the brightest star in the sky.

Even at such a great distance, the Sun is still extremely bright.

Its brightness at this moment is the same as the brightness of the brightest full moon visible from Earth. However, the moon is a disk-shaped structure, while the sun at this moment is just a point-shaped structure.

It is a small dot, but it has the same brightness as the disc-shaped moon, which makes it look extremely bright, even slightly dazzling.

The power of the sun was displayed to Li Qingsong without reservation at this moment.

Even though the distance between us is nearly 100 billion kilometers, the sun can still send light and cast shadows on people or objects.

Depending on how it is calculated, the boundary of the solar system is at different distances.

Calculated based on the orbits of major planets, Neptune's orbit is the boundary of the solar system, about several billion kilometers away from the sun.

Calculated by the radiation boundary, that is, the distance that plasma from the sun can be transmitted in interstellar space, the boundary of the solar system is about 100 billion kilometers away from the sun.

Beyond this distance, the plasma from the Sun can no longer travel. Beyond this is the world of interstellar high-energy radiation.

But if calculated by gravitational boundary, the boundary of the solar system extends directly to the Oort Cloud.

According to previous theories of human civilization and Li Qingsong's research, Li Qingsong believes that the solar system was formed about 46 billion years ago, and the Oort Cloud is the residual material of the protoplanetary disk in the early formation of the solar system.

They were initially relatively close to the Sun and formed in a similar process to asteroids. However, after the formation of the two giant planets Saturn and Jupiter, through a series of gravitational battles, these small celestial bodies were thrown to the edge of the solar system by gravity, and after a long time, they eventually formed the Oort Cloud.

The Oort Cloud is about 1 light-year away from the Sun, or more than 9.4 trillion kilometers.

At this moment, Li Qingsong's fleet has crossed the radiation boundary of the solar system, but is still far from the gravitational boundary.
