Day after day passed.

Busy preparations are in progress, and now that the partnership with the Thoth civilization has been decided, it is necessary for people to discuss the general cooperation plan during this period of time.

After scientific discussions, it was found that people's current scientific and technological strength is far from being able to successfully survive the neutron star collision, and they must use the interstellar trading market to make a leap forward in their civilization.

And the 1,000 amoeba points on hand have become the most important lifesaver.

"Ladies and gentlemen, after demonstration, we have found that it is necessary to observe the collision of neutron stars at a distance of 120-200 astronomical units in order to obtain more accurate data."

The physicist standing on the stage, named Joseph Needham, simulated the entire neutron star collision process in an electronic computer.

"However, 120 AU, too close. There is a high probability that our equipment will be destroyed in that instant. ”

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

Zhang Yuan frowned, thoughtful in his heart. Theoretically, 120 AU is already quite a large number.

How far is the Sun from Pluto?

There are only 49 astronomical units.

At a distance of 49 AU, Pluto receives very little sunlight, and its surface temperature is only minus 201.11 degrees Celsius.

Well, 120 AU is a much longer distance......

But!

This distance, compared to the most violent disaster gamma ray explosion in the universe, is equivalent to a nuclear bomb with a million ton yield, and the distance outside the crater after the explosion is about one centimeter!

How to defend, even for a minute or two, is a big problem.

"So it's best for humanity to be able to find a planet around here that can shelter the observation equipment from the 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 be maintained for a longer time.

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

The Sedna star in the Solar System is estimated to have a perihelion of about 76 AU and 937 aphelion respectively, and its orbit from the Sun is an ellipse and fluctuates.

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

Professor Joseph Needham said with a little excitement: "...... Let me introduce the general plan, after we reach that area, we must be the first to observe whether the neutron stars will collide immediately. If two neutron stars collide in a few years or decades, and we don't even have time to build, let's run away first, and it is impossible to lose our lives! ”

"It's just that all the money we paid has been wasted, and the battle stars of the Huantai civilization will eventually return to the trading market. It's been discussed, and it's no problem to let this battle star take us back for free. ”

There was a commotion in the audience, some people thought it was a little funny, and some people just shook their heads helplessly.

None of this can be calculated, everything can only be done by luck.

"Of course, in the case of a high probability, if the two neutron stars do not collide immediately, this scale is that they will not collide within 10,000 years, and our two civilizations will choose to build two battle stars."

"These stars are not for living, but for experimentation. Only the most basic mobility is required, and the rest is not required. ”

He drew a circle on the screen, in the outer regions of the two neutron stars: "We need to build two planetary fortresses." Place a planetary fortress at 120 AU for astronomical observations. ”

Then another small circle was drawn: "Another planetary fortress, after all the work is done, try to hook the neutron star collision...... It's like this. ”

Compared with neutron stars, the gravitational force of a planet is small, but it still has a certain gravitational force, and it can form a simple three-body motion with two rapidly rotating neutron stars.

The three-body motion is an unstable motion that is capable of accelerating the time of the neutron star collision.

According to computer simulations, the planet constantly interferes with the movement of the neutron star through the planetary engine, and then after approaching the neutron star to a certain extent, it is immediately torn apart by the violent gravitational force, and then various materials fall to the neutron star at sub-light speed, producing a super explosion. At the same time, the rotation of neutron stars around each other will be disturbed, and the collision time will be shortened.

"It's a fairly rough plan in the hypothetical, and there may be some adjustment to local conditions when the time comes."

"Professor, I have a question." A man who looked like a reporter raised his hand and asked, "Can you really accurately predict the collision time of neutron stars?" What if the calculations are inaccurate? ”

Joseph Needham nodded affirmatively: "If it's a double star movement, of course it can be predicted more accurately!" ”

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

Under normal circumstances, two small balls attract each other in space, forming a state of equilibrium that rotates at high speed with each other, seemingly without any energy loss, and can go around forever.

However, for ultra-high-quality neutron stars, the space distorted by gravity is like a water wave, which has a great resistance to its own motion, and slowly, after the kinetic energy is lost to a certain extent, the two neutron stars will "snap" and collide together.

Of course, for stars, any scale is based on millions of years, and there is a probability that they will collide together in the next second, or it may take a million years, or even a hundred million years.

"All in all, if we look at two neutron stars up close, we can calculate the approximate collision time, and if there is a million-year scenario, we won't have to wait a million years...... Consume a planetary fortress to accelerate the neutron star collision, which is also a good result. ”

It's a big amazing big deal!

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

Zhang Yuan sat in the audience, thinking carefully, this meticulous plan is the largest project of mankind so far. Even if the two civilizations cooperate, it could last for thousands of years.

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

We must do a good job in internal mobilization, and we must also do a good job in external diplomacy.

Cooperating with the Thoth civilization is a better choice if it is not handled well, and it will be better if it is handled well, and a civilization will build a war star, and the amount of work will be directly reduced by half. What's more, if the two civilizations jointly defend against cosmic-level disasters, the success rate will be greater.

It's a huge challenge, not just in terms of technology, but also in terms of spirituality...... It is difficult to fully predict what will happen in the future, but can human beings complete a plan that has lasted for thousands of years without forgetting their original intentions?
