Earth Era

As time passed, the earth, the planet that carried all the hopes of human civilization, finally turned into an ordinary star. At least that's how it seems to Zhao Lan. Apart from being a little brighter than other planets in the galaxy, the earth has no other characteristics.

Zhao Lan's Sylvia spacecraft has been sailing in the vast universe for three days. During these three days, Li Yunfan sent Zhao Lan another batch of observation information about the empty universe where he was. Because the spacecraft Li Yunfan was riding was not a professional scientific research spacecraft, the information sent was incomplete and inaccurate, but even so, the information was enough to make Zhao Lan feel heavy in his heart.

That universe... is really scary. A backwater, an emptiness. Zhao Lan even doubted whether there was a concept of "time" in that universe. Time is a physical quantity that describes the movement of matter. Without matter, there would naturally be no time, or in other words, time has no meaning. For that universe, there is no difference between ten thousand years or one hundred million years. Under such circumstances, the spacecraft Li Yunfan was riding on could actually maintain the normal passage of time. This was the most incredible thing for Zhao Lan.

Moreover, it does not seem to be troubled by entropy increase or energy loss. An empty, completely empty universe has a fixed entropy value, while a spaceship with matter arranged according to a certain pattern has a lower entropy value. According to the laws of cosmology, the matter in the spacecraft will tend to diverge, and eventually spread completely evenly throughout the universe. Although this time will be very long according to current cosmological theories, it is not a normal universe, and who knows what strange physical laws will be used in that universe.

Everything is unknown there, and at the same time, everything is dangerous. It can be said that Li Yunfan's life is in danger at any time. But even so, Li Yunfan still maintained a normal psychology and emotions, not affected by the environment at all. This is what Zhao Lan admires most.

The more he got to know Li Yunfan, the more Zhao Lan admired him. Sometimes Zhao Lan even thinks like this: "If this star disaster is real, if human civilization really faces the threat of life and death crisis... maybe human civilization really needs to rely on Li Yunfan to survive this time." Crisis. Maybe Li Yunfan can really turn the tide like my ancestor Zhao Huasheng. After all, this person is so powerful, I don’t know who else in human civilization can compare with him."

During these three days of sailing. Zhao Lan is already nearly 30 million kilometers away from the earth, and still less than 1 million kilometers away from the calculated point in Lobachevsky space. After confirming some things with Li Yunfan, Zhao Lan set the spacecraft to automatic navigation mode, then left the driving seat and came to the control cabin, preparing to operate the most sophisticated observation instruments to start measurements.

The optical instrument first projects a circle on a flat curtain prepared in advance and placed in a vacuum environment. And stored the circumference data of the circle in the instrument, Zhao Lan controlled the observation instrument and began to measure the diameter of the circle. After getting the diameter data, Zhao Lan divided the circumference and diameter to get a series of data.

"Three points, one, four, one, five, nine, two, six, five, seven..." Zhao Lan recited this string of numbers silently. This string of numbers was very familiar to Zhao Lan. In fact, as early as more than ten years ago, Zhao Lan had memorized all the numbers from the decimal point to the thousandth place in this string of numbers. Zhao Lan compared this series of numbers with the precise pi figures obtained through mathematical calculations through a program, and came to the conclusion: "The instrument's measurement accuracy of pi is as high as 300,000 digits after the decimal point."

Because this series of numbers is exactly the same as the first 300,000 digits of the standard pi, there is only a slight difference after the 300,000 digits. This shows. Among the measurement data of this instrument, at least the first 300,000 digits are correct.

Zhao Lan changed the size of the circle projected by the optical instrument, and then repeated the measurement several times. This was finally confirmed. After confirming the accuracy, Zhao Lan stopped operating. Instead, the wait began.

The spaceship was still moving quietly. Because the spacecraft was constantly decelerating, it took the spacecraft a full eight hours to travel the million kilometers. Then the spacecraft remained stationary relative to the sun and stopped here.

The universe here is no different from the universe elsewhere. They are all equally empty and dark. Zhao Lan could still see the stars in the sky through the porthole, the bright sun in the distance, and the slightly blue planet next to the sun. The spacecraft is also working normally here, and the navigator and gyroscope are also working normally, without any abnormalities.

But Zhao Lan knew that this was unusual. Because mathematical model calculations show that this place must be different from elsewhere. If this is normal space, it means that there is an error in the mathematical calculation process. And Zhao Lan believed that such a thing could not happen.

Zhao Lan took a deep breath. The optical instrument was manipulated to once again reflect a circle in the vacuum environment, and then the measuring instrument was used to measure it again. Two numbers came up quickly. It was entered into the calculation program and started to calculate. Soon, the number extended to hundreds of thousands of digits, and it was still extending rapidly.

The measurement accuracy of this instrument is 300,000 digits, so too many digits are completely unnecessary. Zhao Lan stopped the calculation process, and then input the pi data obtained this time into the comparison program through the program. The program only runs for a moment and the results of the calculation are presented.

Zhao Lan narrowed his eyes slightly and looked at the calculation results. The calculation result is just as Zhao Lan expected. The pi data measured in this Lobachevsky space... is the same as the previous 237,000 pi data measured in the Euclidean space. One thousand, six hundred and eighty-four are completely consistent, but there is a deviation at the two hundred and thirty-seven thousand, six hundred and eighty-five.

The number measured in standard space is four, but the number measured here is six.

And Zhao Lan already knew that the measurement accuracy of this instrument was 300,000 digits. In other words, the first 300,000 digits of these two different numbers are correct, but they are different from each other. This can only prove that... there is a change in space. There is some distortion or unevenness in space here, and it is this change in space that causes the change in pi.

The result of one measurement may be somewhat inaccurate, so Zhao Lan repeated the measurement dozens of times. But the results of each measurement were exactly the same. The number above that digit was six every time.

Zhao Lan took a deep breath, stopped measuring, and stored all the calculation data into the computer. As things have developed so far, everything Li Yunfan said has been confirmed, and... the real situation is worse than what Li Yunfan said.

Because Zhao Lan noticed that the increase in the curvature of space seemed to be accelerating. The greater the curvature of space, the faster the stars disappear, and the faster the earth falls into the empty universe. This is obviously not a good thing for human civilization.

Zhao Lan felt a slight sense of urgency in his heart.

"I have finished the measurement." Zhao Lan whispered, "Your words have been confirmed. The space around the earth, or in the solar system, has indeed changed. The earth... is indeed falling into the empty universe. .”

This is a very bad result. Before this measurement result appeared, Zhao Lan even prayed in his heart that this would not happen. Zhao Lan would rather these experiences were just deceived by Li Yunfan and his organization than be true. Because the deception only targets one person, and if the disaster of stars is true...it is facing all mankind.

By now, all the hopes in Zhao Lan's heart were finally completely shattered. The cruelest truth has been presented to Zhao Lan.

Li Yunfan's reply arrived after a communication delay, and his voice was still lazy: "Now you finally believe me?"

Zhao Lan did not answer this question directly, but asked a little helplessly: "What should I do? What should our human civilization do? The current technological level of our human civilization is not enough to exert an influence on space... Can we Can we find a way to stop the earth from falling into the empty space?"

Facing Zhao Lan's slightly panicked question, the laziness in Li Yunfan's words finally disappeared, replaced by steel-like determination: "Zhao Lan, you have to believe that the potential of our human civilization is unlimited. As long as a disaster occurs , there will definitely be a hero who can turn the tide and change everything. During the solar crisis, your ancestor Zhao Huasheng was such a hero, and in this crisis, there will definitely be a hero who can rival Zhao Huasheng."

The strong confidence and determination in Li Yunfan's words made Zhao Lan finally calm down. Zhao Lan whispered: "I'm sorry, I, I lost my temper. Indeed, we still have time, and it is far from the time of despair. I will return to Research Institute 105 now to report these things to the world. Human scientists announced it. I believe that with the efforts of all mankind, we will definitely find a solution to the problem."

"Don't forget to share your research conclusions with me." Li Yunfan said, "I don't have the ability to conduct scientific research now, but I think that as long as I have the support of data and information, my brain can still make some contributions to mankind. .”

Zhao Lan replied in a low voice: "Okay." (To be continued ~^~)
