"According to the archives of that civilization, there is an ancient civilization in the universe. After the civilization developed to level 8, they suddenly lost interest in continuing to evolve."

"Put all your resources and energy into their "sowing" plans."

"The so-called "sowing" plan is to help guide some new civilizations through external forces and speed up their growth."

"And oil meteorites are part of the "Sowing" plan, which can help new civilizations pass through the level 1 civilization stage as soon as possible."

"So, I say the earth is lucky."

The Pajero people finally finished their explanation, and Li Mo was stunned.

In the story told by Pajero, two super civilizations have already appeared to stop evolving after reaching level 8. From the difficulty of civilization evolution, it can be imagined that there should not be many level 8 civilizations in the universe. Moreover, the seemingly ordinary oil on the earth is actually the work of a super civilization in the universe.

Was it a coincidence? Li Mo did not express his suspicion because it had nothing to do with the problem.

"Due to the lack of convenient energy such as oil, we Pajero people could only use stellar energy and biological energy in the early days. Then they converted this energy into electrical energy and then drove the spacecraft through electrical energy."

"The planet is too small and the universe is too big. With the development of the Pajero civilization, the population base is increasing, and the limited space of the Pajero Star can no longer meet the needs of survival."

"A planet 300 million kilometers away attracted the attention of the Parogero people. By launching unmanned probes, the Parogero people were surprised to find that only after a simple transformation can the planet become our second home."

“Immigration to alien planets has become the top priority!”

"The term first mission was translated from Earth language, but it is still very different from the first mission in your Earth language."

"Do you know the character of the earthlings and what it looks like in the eyes of us Pajero people?" The Pajero people with big heads may find it difficult to explain the meaning of "priority task", and began to extend the interpretation.

"Lid-back! Romantic!"

"You can waste precious time and energy to pursue illusory art. There is also the most luxurious behavior among human beings, that is, love."

"On our planet Pajero, all behaviors that are not conducive to the development of technology and military are forbidden. Even when the Pajero people are sleeping, they must connect their brains to the computer to provide computing power for the planet."

"So the first task I just mentioned is that the whole nation exists just to be able to successfully immigrate to the second home."

"After hundreds of years and thousands of failures, the first Pajero spacecraft finally landed on the remains of the predecessors and boarded the second home."

"The Pajero people also had the ability to travel interstellar for the first time. Of course, the Pajero Starship could only reach 0.1 times the speed of light at that time."

"Are you very surprised that I used the speed of light as the unit of spacecraft speed here? Do you think I was translated again?" The Pajero man with a big head began to ask again. Li Mo knew that he was going to tell the key point of the problem.

“no,no,no!”

"The speed of light is the only standard unit for measuring speed in all high-level civilizations in the universe!"

"We Pajero people only understood this principle after reaching the level 2 civilization. Do you know why?" The Pajero people with big heads began to ask and answer questions again.

"Why do civilizations that can already pass through wormholes still use the speed of light as the unit of speed?"

"Because in this universe, the speed of any matter can't move beyond the speed of light."

When the big-headed Pajero people talked about this, Li Mo couldn't help but ask: "Since the speed of light is the fastest, why can some super civilizations travel through the entire galaxy in a very short time? The diameters of those galaxies are usually several light years away."

"Please note that the noun I use is "speed", and the question you ask is "distance". Fast speed does not equal distance." The big-headed Pajero replied.

"Almost all spacecraft that can fly across galaxies use super gravitational field technology. This technology can distort the surrounding space and space to form a hollow, and the hollow exit is the destination of the spacecraft."

"So the speed of this kind of spacecraft does not exceed the speed of light, it just takes a shortcut."

Sure enough, time and space can be bent. In classical mathematics, there is a theorem that the straight line between two points is the shortest.

Imagine that there are two points on a white paper, and the straight line distance between them is the shortest. However, if you fold the paper with the center of the two points as the center axis in half, the distance between them will be infinitely close to 0, which is shorter than the straight line distance just now. And the super gravitational field may play a role of "folding halfway" here.

Li Mo already understood why alien spacecraft with speeds not exceeding the speed of light can swim in the universe. They are the "shortcuts" created by the super gravitational field.

"With the development of technology, with the help of anti-gravity field, the speed of our Pajero spacecraft has slowly approached the speed of light. At that time, a craze arose in Pajero, which is to see who made the spacecraft can reach the speed of light first." The Pajero people with big heads continued.

"The first spacecraft to reach the speed of light will inevitably be ranked as the Monument of Civilization. This is a great honor. For a time, countless spacecraft manufacturing factories emerged on the planet Pajero, and their purpose is to build the fastest spacecraft."

"Even, there are programs of spaceship speed competitions in the official information broadcaster."

"At this moment, a sudden disaster disrupted this kind of shipbuilding competition."

"Do you know what happens when both aircraft are flying in a straight line at more than half the speed of light and their heading is in the opposite direction?"

Two aircraft are traveling opposite each other at more than half of the speed of light? Then, with one of the spacecraft as a reference, the speed of the other spacecraft must exceed the speed of light.

Is this contrary to the truth that the fastest speed of light? Li Mo feels this is a bit like a paradox.

"Based on the relative speed calculation, if one spacecraft is set to be absolutely still, then the speed of the other spacecraft will exceed the speed of light. So this situation does not exist." Li Mo quickly calculated in his heart.

"Hahaha!" The big-headed Pajero people burst into laughter.

"This is your theory of relativity on earth. I have to say that humans on earth are really a race with wisdom bursting out. Although they have not entered the universe, you can accurately calculate the speed of light and understand the essence of the relative nature of time and space. But you have to understand one truth, that is, this universe is unique, and the only means absolute."

"So this theory of relativity is not suitable for velocity calculations in the context of the absolute universe. Because from this cosmic angle, their velocity does not exceed the speed of light."

"So this situation exists and does not violate the laws of the universe."

"But!" The big-headed Pajero man changed his tone.

"Although these two spacecraft are equipped with state-of-the-art nanolidars and equipped with cosmic positioning coordinates, something strange happened, they actually disappeared from each other's eyes."

"That is, when the relative speed of the two spacecraft exceeds the speed of light, they cannot detect each other."

"But for this universe, they are in a state of about to collide."

"In this critical moment, the surveillance officer who monitors the competition uses quantum waves to issue emergency commands to adjust their direction."

"But these two spacecraft seemed to have not received the order."

"The tragedy happened like this. The two spacecraft collided near a planet. The extremely high speed triggered a chain reaction, and the energy released exploded to pieces that innocent planet. All the Pajero people who were collecting energy on the planet were killed."

"What the official concern about this matter most is not the energy planet that was blown to pieces, nor the thousands of Pajero citizens who died in the line of duty."

"It's why the two spacecraft did not follow the orders issued by the surveillance officer."

"The Pajero people who do not follow the orders? This kind of thing has never happened in Pajero's history."

The tone of the Pajero man with a big head was full of doubts. This doubt made Li Mo feel heartbroken. The countless lives sacrificed could not match one problem?

"To find out, the Pajero Academy of Sciences conducted a new experiment in a blank star field. Two Pajero pilots flew two aircraft respectively, traveling opposite each other at a speed of more than half of the light. The difference is that the two fighters were equipped with real-time monitoring black boxes."

"The tragedy happened the same way. After the surveillance officer issued an alarm signal, the two aircraft still collided together without changing direction. The pilot was blown to ashes at that time, but this time, the black box was saved."

"After analysis, there was a creepy audio in the black box of the spacecraft. At that time, the surveillance officer issued the order "Flight 01, turn left 0.001 degrees." However, the audio data stored in the black box of the spacecraft was, "Flight 01, keep sailing." After analysis, the sound in the black box was the voice of the surveillance officer himself."

Hearing this, Li Mo was confused, and the Pajero people with big heads seemed to be telling a thrilling story. Pajero's surveillance officer's order was "changed" in an instant? This is unscientific! He asked anxiously: "Why did this happen."

"Yes, why does this happen? This is also a problem that we Pajero people can't figure out." The Pajero people with big heads replied, "It was not until we stepped into the threshold of level 4 civilization that the Pajero Academy of Sciences discovered a new law of the universe, that is, the law of unmeasurable relative speed of light, which solved this problem."

Is the relative speed of light unpredictable? Is it unpredictable or unmeasurable?

"What is the relative speed of light that is unpredictable?" Li Mo asked in confusion.

The big-headed Pajero did not directly answer his question, but continued to talk.

"The Pajero Academy of Sciences found that once two downward spacecraft have a speed of more than half the speed of light, any attempt by the outside world to reverse the course will be distorted by a mysterious force."

"So, from then on, Pajero officially stipulates that the speed of any aircraft cannot exceed one-half of the speed of light."
