Humanity is missing, luckily I have billions of clones.

Chapter 238 Luggage
To pile up various materials and create a flying star out of thin air is probably like a fairy tale for ordinary civilizations, and they dare not even think about it.

The industrial capacity and coordination capabilities it requires are simply too enormous.

And now, Li Qingsong has actually achieved this.

Li Qingsong saw that because of its huge mass, this planet, which was completely artificially created by Li Qingsong, even had some characteristics of large natural planets.

This flying star already has a surface gravity that cannot be ignored.

At this moment, a clone wearing a space suit came to the surface of the planet under the control of Li Qingsong.

He just stood on a container without any external support.

Normally, in the absence of gravity in space, any slight disturbance would cause the clone to fly away from the planet.

But at this moment, even though he kept walking on the surface, he was always firmly attached to the surface of the planet.

Because the gravitational acceleration on the surface of this planet reaches about 5.31 mm per second squared, which is about one 1800th of the Earth's gravity!
The clone continued to move forward, and when he faced a ravine in front of him - actually a gap between the piled containers, he suddenly jumped up.

This jump reached a height of more than ten meters. After flying to the other side of the ravine and reaching the highest point, he fell downwards at an acceleration of 5.31 mm per second squared. In the end, he still landed on the surface of the planet instead of flying into space.

Because the planet's escape velocity reaches about 23 meters per second.

Without reaching this speed, no matter how high the clone jumps, it will not be able to escape the gravitational field of the flying star.

The clone ran quickly on the surface of the planet, checking the surface as he ran.

His running speed became faster and faster, first five meters per second, then ten meters, twelve meters, until now, his running speed reached 18 meters per second.

Then, with another jump, the clone's body was suspended about 30 meters above the surface of the flying star.

This time, he didn't fall down again.

Because the speed of 18 meters per second has reached the orbital speed of the planet.

If there were no other interference, the clone would always revolve around the flying star at a speed of 18 meters per second, with a speed of less than 5 hours, just like the artificial satellites revolving around the earth.

After flying around the planet twice, the clone activated the thrusters on his space suit and descended to the surface of the planet again.

Gravity is the weakest of the four fundamental forces.

Its strength is even so low that an ordinary person can easily resist it.

For example, an ordinary person on Earth casually picks up a pen - this is a very common thing. But from the perspective of the gravitational field, it is an ordinary person who, relying on his own strength, easily overcomes the gravitational pull of the entire Earth on the pen.

This shows how low the strength of gravity is.

And now, through the accumulation of matter, he has actually created a gravitational field that is strong enough to affect macroscopic objects. This feeling makes Li Qingsong feel very wonderful.

Li Qingsong even observed that the flying star he created had created an extremely thin "atmosphere" for itself due to its own gravitational field.

Of course, it's just the atmosphere in a microscopic sense.

The gravitational field of the meteor briefly attracted some of the interstellar gas to its vicinity, creating a higher density around the planet than elsewhere. Li Qingsong calculated that the gas density at the planet's surface was about twice that of the outer atmosphere, reaching approximately 20 atoms per cubic centimeter.

Expecting such a thin "atmosphere" to generate any atmospheric pressure is basically a luxury. However, if you insist on calculating, Li Qingsong has also calculated the atmospheric pressure on the surface of the planet at this moment, and concluded that it is about 10^-32 Pascals, which is about 10/37^ of the Earth's atmospheric pressure.

But another indicator is more significant.

After passing through the channel and arriving at the core of the flying star, the clone controlled by Li Qingsong felt obvious atmospheric pressure.

Because of its own gravity, the matter that makes up this planet has an inward squeezing force. As a result, the gas at the core of the planet is squeezed, causing it to have an atmospheric pressure about half that of the Earth.

This level of atmospheric pressure is sufficient to support human survival.

So, in a cabin at the core of the planet, the clone took off his space suit and began to rely on completely "natural" atmospheric pressure to maintain breathing.

Li Qingsong controlled him to raise his head, and he saw the deep and long tunnel, and the containers, large jars, etc. piled up there layer upon layer.

A strange feeling suddenly arose in his heart.

"Over two hundred trillion tons of matter, in this completely gravityless space, relying on the gravity generated by its own mass, has actually squeezed out a space where a stable atmospheric pressure can exist. It's truly amazing..."

Switching his gaze to another clone, Li Qingsong was filled with emotion as he stood high in the sky and looked at the flying star in front of him.

"After giving it my all, my industrial capabilities have actually reached this point...

A true planet, a planet that is completely man-made, comparable to those naturally formed asteroids, even the larger ones…"

The mass that makes up this planet is almost entirely made up of various materials needed by Li Qingsong.

It is not like an ordinary asteroid or a planet, most of its mass cannot be used.

For example, if he wants to smelt steel, Li Qingsong needs to mine iron ore, and then go through a series of complicated smelting procedures. In the end, he may need to discard up to two-thirds of the mass of the iron ore before he can smelt the steel he needs.

The same is true for other minerals.

To Li Qingsong, those discarded "impurities" were garbage. Not only were they useless, but separating them required a vast amount of energy and numerous industrial facilities.

At this moment, every kind of mineral stored on this flying star has been purified and smelted in advance, and basically exists in the form of elements and alloys.

Hydrogen, protium, oxygen, nitrogen, and other gases have also been purified and separated in advance. Various parts have been manufactured and stored there in advance, so they can be used directly when needed without even processing.

Even if a natural planet is fully developed by Li Qingsong, the maximum mass that can be used by Li Qingsong will not exceed 10% of the planet, and the remaining 90% will be thrown away.

And now, all the mass of this flying star, which was specially built according to Li Qingsong's will, can be used by Li Qingsong, and it is extremely convenient to use, without any waste!

At this moment, the "luggage" for this long voyage has been prepared.

Now, it's time to pack those bags.
