Chapter 521

Day by day.

The busy preparation work is proceeding in an orderly way. Now that the cooperation relationship with TOS civilization has been settled, 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. They must rely on the interstellar trading market to make a leap in their civilization.

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

"Ladies and gentlemen, after demonstration, we found that it is necessary to observe neutron star collisions within 120-200 astronomical units to obtain more accurate data."

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

"But 120 astronomical units, too close. Our equipment will probably be destroyed in that instant. "

"Once the device is destroyed, how can we get the data? Our equipment must fully observe the process that two neutron stars collide, turn into quarks, and finally turn into black holes.... "

Zhang Yuan frowned, thinking deeply. In theory, 120 astronomical units is a considerable number.

How far is the sun from Pluto?

Only 49 astronomical units.

At 49 astronomical units, at this distance, Pluto receives very little sunlight, and its surface temperature is only 201.11 degrees below zero.

So 120 astronomical units is a far greater distance

But!

This distance, compared with the most violent disaster gamma ray explosion in the universe, is equivalent to a million tons of equivalent nuclear bomb, about one centimeter outside 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 for humans to find a planet around here that can shield the observation equipment from wind and rain."

The size of a planet is undoubtedly much larger than that of a spaceship, 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 human beings will find a planet of about 120 astronomical units?

The solar system's Sedna star is estimated to be about 76 and 937 astronomical units, respectively. The orbit from the sun is an ellipse, which will fluctuate.

In other words, it is necessary to build a planetary engine on this planet to control its orbit, so as to control the distance.

Professor Needham said a little excitedly: "I'm not sure Let me introduce the general plan. After we arrive at that region, we must take the lead in observing whether the neutron stars will collide immediately. If two neutron stars collide in a few years or decades, and we don't even have the time to build them, we'd better run first. We can't lose our lives because of this! "

"It's just that all the money we paid has gone to waste, and the war star of Huantai civilization will eventually return to the trading market. It has been discussed that 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 funny, and others just shook their heads helplessly.

There is no way to calculate these, everything can only rely on luck.

"Of course, if the two neutron stars will not collide immediately, and the 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 for people, but for experiments. Only the most basic mobility is required, and the rest are not required. "

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

Then he drew another small circle: "another Planetary Fortress, after all the work, tries to hook the neutron star collision It's like this. "

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

The three body motion is unstable and can accelerate the time of neutron star collision.

According to the computer simulation, the planet constantly interferes with the motion of the neutron star through the planetary engine. After approaching the neutron star to a certain extent, it is immediately torn up by the violent gravity, and then all kinds of materials fall to the neutron star at the speed of sublight, resulting in a super explosion. At the same time, the rotation of neutron stars will be disturbed, and the collision time will be shortened.

"This is a fairly rough plan in the imagination. 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 we really predict the collision time of neutron stars? What if the calculation is not accurate? "Needham definitely nodded: "if it's a double star movement, of course it can be more accurate prediction!"

In the absence of external interference, the high-speed rotation of two neutron stars will consume energy through gravitational radiation, magnetic radiation and other forms

Under normal circumstances, the two small balls attract each other in space, forming a high-speed rotating equilibrium state. It seems that there is no energy loss and they can go around forever.

But for ultra-high quality neutron stars, the space distorted by gravity is like water waves, which has 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 is based on millions of years. 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 for a million years Consuming a Planetary Fortress to accelerate the neutron star collision is also a good result

It's big, it's amazing!

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, thinking carefully that this meticulous plan is the largest project of mankind so far. Even if the two civilizations cooperate, it may last for thousands of years.

For the whole new human civilization, it is a great challenge in faith, technology and personal safety.

We must do a good job in internal mobilization as well as in external diplomacy.

To cooperate with TOS civilization is a better choice if it is not handled well. If a civilization builds a war star, the engineering quantity will be reduced by half. What's more, if the two civilizations jointly defend against cosmic disasters, the success rate will be higher.

This is a huge challenge, not only in science and technology, but also in spirit It's hard to predict the future completely. Can human beings complete a plan that lasts for thousands of years without forgetting the original intention?
