I kidnapped an alien civilization

Professor SMITH from Princeton talked to you? Professor Wu across the desk looked at him like a torch.

Li Mo scratched his head, Yes, after the welcome meeting, at the guest house.

Hmph, I knew this foreign old man was uneasy and kind. We have invited him so many times at Yanda University, but he didn't come, but this time he came. Professor Wu said angrily, Some people in the school are also confused and think that Foreign monks can lecture, so can't they just come here to make trouble?

Did you refuse? He asked worriedly even though he knew the answer.

Li Mo nodded, I declined, I never thought about studying abroad.

Professor Wu smiled gratifiedly, I'm not against you going out, but your foundation is not solid now. If you go to study abroad rashly, you will break your foundation instead.

Nowadays society blindly praises studying abroad. It is true that some international students have made a name for themselves in foreign countries, but most of them are not suitable for foreign education methods and are lost to everyone.

Speaking of this, he paused, Of course, I also have selfishness. It is not easy to cultivate a talent. I hope you can stay in China.

Li Mo nodded, I know, this country is our home, if everyone goes abroad for their own future, then who will take care of this home?

Upon hearing this, Professor Wu got up and poured a glass of water, and placed it in front of Li Mo. Your words are worth my helping you pour a glass of water.

Thank you. Li Mo quickly stood up and took it, I heard people say that some student union cadres now use the review of scholarships as an excuse for personal gain. I don't know if the department knows about this kind of thing.

Professor Wu was furious: Is there such a thing? I will report it to the department and let them investigate in detail. Universities are a pure land, and some people with ulterior motives are absolutely not allowed to use power for personal gain.

Li Mo looked at Professor Wu who was filled with righteous indignation, and he knew that his choice was correct.

Go to Xiaoshan Laboratory! Li Mo, who got on Wuling Hongguang, ordered Zhou Dayong in the front row.

Dayong nodded and started the car.

You and Brother Qiu, aren't you curious about what the laboratory is for? Li Mo watched him concentrate on driving.

Zhou Dayong chuckled, Mr. Ren said that you are a genius, let Brother Qiu and I fully cooperate with your request, as long as we know this. As for those weird equipment in the laboratory, even if you tell us, we don't understand.

Li Mo looked at his simple and honest appearance, and couldn't help admiring Mr. Ren's discerning eyes.

The unique beauty at the foot of the hill always attracts many urban tourists, and there are tour group buses passing by from time to time along the way. There are even cyclists riding bicycles and wearing cycling clothes traveling together in twos and threes.

When the car drove to the gate of the laboratory, Li Mo saw Brother Qiu at the gate with the security personnel, persuading several tourists. Perhaps seeing that the villa in front of him did have an owner, the tourists left angrily.

What's going on? Li Mo got out of the car and asked.

Brother Qiu carefully inspected the outside of the gate, then turned around and said: I heard from the former security guard that during the years when the laboratory was abandoned, tourists asked to come in and rest from time to time. The security saw them working hard, so they allowed it. The few tourists just came here after hearing the introduction from their friends.

Li Mo nodded, That's a problem. Maybe we should make a sign and place it at the intersection to prevent them from running so far.

I'll let someone prepare it. Brother Qiu nodded and left.

The distance has been calculated. The current distance is 45 astronomical units. The mass of the analyzed planet is 45.126×10kg, and the volume of the planet is 20.21×10㎞. Li Mo stared at the data on the monitor, thinking how to prove the existence of this planet Woolen cloth.

Human beings perceive the world through the five sense organs, namely eyes, nose, mouth, ears and tongue. Specific performance in perception is vision, touch, smell. As for distant planets, humans can only observe them through telescopes and scientific instruments.

Use a telescope to observe the planet, because the planet itself does not emit light. It can only be observed by using the light reflected by the planet from the star. Nowadays, many scientists also use infrared telescopes to detect the universe, but they are also based on observations of planetary radiation.

If there is a planet whose core does not heat up and whose surface does not reflect the sun's rays, can it avoid human observation?

Li Mo felt that he had grasped the train of thought, so he picked up the pen and began to calculate.

The original probability is set to 1. Since there are countless stars in the universe, the probability of this kind of star is 99.99%. Therefore, the probability that human beings cannot observe this kind of star is 90.06%.

Sure enough, if such a planet exists, in the short history of human space observation, the probability of not being observed is close to 91%. This shows that his idea is feasible. Looking at the data calculated on the paper, Li Mo is full of confidence.

Your eyes may not be real, your ears may not be real, your experience may not be real, your imagination may not be real, but mathematics is real. The discovery of Uranus was the exact orbit calculated by several mathematicians. At the exact time, the telescope spotted it easily.

In order to determine the orbit of Halley's Comet, several astronomers created a new mathematical model calculation. The three scholars spent several months and finally predicted that the next time Halley's Comet will approach the sun will be around April 1759. The error is about 1 month.

As long as the exact orbit of this unknown planet is calculated, with the current astronomical detection methods, no matter how deeply the unknown planet is hidden, it is still possible to be discovered.

At present, the weight, volume and distance from the earth of the unknown planet are known, and accurate orbital data of this planet are required. This is simply impossible, because there are too many unknown conditions.

Li Mo searched for data on the abnormal orbits of the stars in the solar system through his mobile phone, because if such a large unknown planet exists, it will definitely have a gravitational force on the surrounding stars and disturb their orbits.

He saw these two news

1. On January 20, 2016, Mike Brown and Konstantin Batygin of the California Institute of Technology published their research results in the Astrophysical Journal, announcing the discovery of abnormal orbits of 6 celestial bodies in the Kuiper belt of the solar system. These 6 Although two celestial bodies are revolving at different speeds, their orbits have the same inclination angle, and the angle towards the sun is similar, and the chance of this happening under natural conditions is only 1 in 14000 (0.007%)

2. In 2012, Professor Rodney Gomes of Brazil's National Astronomical Observatory in Rio de Janeiro reported the results of research on unknown planets at the American Astronomical Conference. Gomes found that the orbits of about 6-7 celestial bodies in the Kuiper belt are very strange, including the very famous Sedna (Sedna), which is different from the normal orbits predicted by the existing solar system models.
