Chapter 529

Day after day passed.

Busy preparations are being carried out in an orderly manner. Since the cooperative relationship with the TOS civilization has been determined, people must discuss the general cooperation plan during this period of time.

After scientific discussion, it is found that people's current scientific and technological strength is far from being able to survive the neutron star collision. We must make a leap in our civilization with the help of the interstellar trading market.

The 1000 amoeba points on hand have become the most important life-saving straw.

"Ladies and gentlemen, after demonstration, we found that we must observe the collision of neutron stars within 120-200 astronomical units in order to obtain more accurate data."

The physicist standing on the stage is Joseph Needham. He simulated the whole process of neutron star collision in an electronic computer.

"But 120 astronomical units, too close. Our equipment was probably destroyed at that moment. "

"Once the equipment is destroyed, how can we get the data? Our equipment must completely observe the process of two neutron stars colliding, transforming into quark stars and finally into black holes... "

Zhang Yuan frowned and thought deeply. In theory, 120 astronomical units is already a considerable number.

How far is the sun from Pluto?

Only 49 astronomical units.

At 49 astronomical units, at this distance, Pluto receives very weak sunlight, and its surface temperature is only minus 201.11 degrees Celsius.

Well, 120 astronomical units is a further distance

But!

This distance, compared with the most violent disaster gamma ray explosion in the universe, is equivalent to a million ton equivalent nuclear bomb. It is about a centimeter away from the crater after the explosion!

How to defend, even for one or two more minutes, is a big problem.

"So it's the best way. Near here, humans can find a planet that can shelter the observation equipment from the wind and rain."

The size of a planet is undoubtedly much larger than a spacecraft, and it can also ensure that the equipment can maintain operation for a longer time.

However, this kind of thing is a small probability event. Who can guarantee that mankind can just find a planet of about 120 astronomical units?

The sun point and aphelion point of Sedna star in the solar system are estimated to be about 76 astronomical units and 937 astronomical units respectively. The orbit from the sun is an ellipse and fluctuates.

In other words, only by establishing a planetary engine on this planet and controlling its orbit can we control the distance.

Professor Needham was a little excited and said: "... Let me introduce the general plan. After we reach that star region, we must take the lead in observing whether neutron stars will collide immediately. If two neutron stars collide in a few years or decades, and we don't even have time for construction, we'd better run first. It's impossible to lose our lives! "

"However, all the money we have paid has been wasted, and the war star of Huantai civilization will eventually return to the trading market. It has been discussed. There is no problem for this war star to bring us back for free. "

There was a lot of noise under the stage. Some people thought it was a little funny, and others just shook their heads reluctantly.

There is no way to calculate these. Everything can only rely on hidden luck.

"Of course, probably, if two neutron stars do not collide immediately, this scale is that they will not collide within 10000 years. Our two civilizations will choose to build two war stars."

"These war stars are not used to live people, but for experiments. Only the most basic mobility is required, and the rest are not required. "

On the screen, he drew a circle around the periphery of the two neutron stars: "we need to build two planetary fortresses. Place a Planetary Fortress at 120 astronomical units for astronomical observation. "

Then he drew another small circle: "another Planetary Fortress, after all the work, tried to hook up the neutron star collision... Like this."

Compared with neutron stars, a planet has small gravity, but it still has a certain gravity. It can form a simple three body motion with two rapidly rotating neutron stars.

Three body motion is an unstable motion, which can accelerate the time of neutron star collision.

According to the computer simulation, the planet continuously interferes with the movement of the neutron star through the planetary engine. After approaching the neutron star to a certain extent, it is immediately torn apart by the violent gravity, and then various substances fall onto the neutron star at the speed of sub light, resulting in a super explosion. At the same time, the mutual rotation of neutron stars is disturbed, and the collision time will be shortened.

"This is a fairly rough plan in the imagination. At that time, it may be adjusted to a certain extent according to local conditions."

"Professor, I have a question." A reporter like man raised his hand and asked, "can the collision time of neutron stars really be predicted accurately? What if the calculation is not accurate? "

Needham nodded affirmatively: "if it is a double star movement, of course, it can be predicted more accurately!"

In the absence of external force interference, the high-speed rotation of the two neutron stars will consume energy in the form of gravitational radiation and magnetic radiation. "

Under normal circumstances, two small balls attract each other in space to form an equilibrium state of mutual high-speed rotation. It seems that there is no energy loss and can rotate forever.

However, for ultra-high quality neutron stars, the space distorted by gravity is like water waves, which has a great resistance to their own motion. Slowly, after the kinetic energy is lost to a certain extent, the two neutron stars collide with each other.

Of course, for stars, any scale takes millions of years as the basic unit. There is a probability that they will collide in the next second. It may take another million years, or even 100 million years.

"In a word, as long as we observe two neutron stars at close range, we can calculate the approximate collision time. If there is a million years, we will not wait a million years... It is also a good result to consume a Planetary Fortress to accelerate the neutron star collision."

This is a big, amazing big hand!

Many people are stunned. According to the current human productivity, it will take thousands of years for a planet to have initial power, just to accelerate the neutron star collision?

Zhang Yuan sat under the stage and thought carefully. This careful plan is the largest project of mankind so far. Even if the two civilizations cooperate, it may last thousands of years.

For the whole new human civilization, it is a great challenge to faith, science and technology and human security.

We must do a good job in internal mobilization and foreign affairs.

Cooperation with the TOS civilization is a better choice if it is not handled well and brings trouble. Building a war star by a civilization directly reduces the amount of work by half. Moreover, the success rate of the two civilizations in jointly defending against cosmic disasters will be greater.

This is a huge challenge, not only at the scientific and technological level, but also at the spiritual level... It is difficult to fully predict the future. Can mankind not forget to complete a plan lasting for thousands of years?
