The last human in the universe

Chapter 52 Probability
At this moment, there are about 16 adults in the entire human civilization. Except for some industries that are necessary to maintain the operation of society, such as food production, the rest are all invested in military-related industries, and the rest of the industries are temporarily stopped. .

The supply of various non-staple foods has been greatly reduced, and commercial activities have almost disappeared.Almost everyone I met on the road had serious expressions and hurried steps.The major factories are busy day and night, never stopping.

The first generation of "dust" class spy satellites are under intensive development.Once successfully manufactured, they will be sent to the surroundings of the deep space star to collect all information about the deep space star.Improved versions of the electromagnetic gun and deep-space surveillance radar are also being developed.The construction of the space dock and the roller base has not been put down either.

"Build a second space elevator."

Zhao Changxing gave the order.

It is almost certain that if it cannot be exterminated in this revenge, then the confrontation with the deep space civilization will be long-lasting, and the time span may be as long as several centuries.In this long confrontation, not only must try to weaken the opponent, but also try to improve their own strength.Therefore, large-scale construction tasks should not be stopped, but should be accelerated.

In fact, Zhao Changxing classified this into the category of military-related industries.

Time passed bit by bit, and two years passed in the blink of an eye, reaching the 246th year of the new calendar.

During this period of time, the communication between deep space civilization and human civilization has never been interrupted.Both parties seem to be discussing the details of cooperation in good faith, but so far there has been no concrete progress.

Twenty of the latest generation of flame-type transport spacecraft have been manufactured, and some of them have assumed the responsibility of connecting space and the surface.Another ten small one-man combat spaceships were manufactured by the spaceship factory and delivered to the military.

These small single-person combat spaceships are propelled by chemical fuels, and do not have a life support system inside, but need to rely on space suits to survive.The weapon equipped on them is a gunpowder-driven double-barreled machine gun with a firing rate of up to 100 rounds per minute, and the bullet ejection speed reaches 1.2 kilometers per second.

They also don't have long-range interstellar combat capabilities, and they can't leave Sedna too far away.Because they have extremely limited fuel and oxygen reserves.

Taken together, they are more like the space-reformed versions of the armed helicopters of the Earth era.

This kind of spacecraft is code-named Wu-1 in the War Council.

The members of the War Council were quite dissatisfied with this thing. They generally believed that this thing had no practical value, but in the end they had to hold their noses and accept it.

In the military system, in addition to land-based or space-based electromagnetic guns, which can be regarded as fixed firepower weapons, it is obvious that there is also a need for a weapon that can move in a large range, flexibly choose attack locations, and flexibly perform combat tasks. occupy this ecological niche.And the Wu-1 combat spacecraft is already the best design solution that the military factory can come up with at the moment, don't you?Then there is no more.

So at this stage, these ten Wu-1 combat spacecraft were temporarily used as training aircraft, and they took on the responsibility of searching for spy satellites in space and capturing or destroying them.

At this time, the No. [-] dust-level spy satellite finally passed various inspections, and achieved satisfactory performance in the actual verification.

Compared with the Wu-1 combat spaceship, the members of the war committee really couldn't say anything dissatisfied with the dust-level spy satellite.First of all, it has a high optical detection capability. At a distance of 20 kilometers, the highest resolution can reach the kilometer level, and it is small in size. After being equipped with a special coating, it has a relatively good stealth ability and can effectively avoid radar detection. scanning.The high-gain directional antenna can also stably transmit the detected data back to the Sedna star and receive instructions from the Sedna star.

At this stage, it has almost achieved the ultimate in all aspects.

Therefore, under the launch of the launch platform that people also developed recently, they have acquired an initial speed of 3.2 kilometers per second, and flew towards the deep space star.

Moving at this speed, they will reach the vicinity of the deep space star in about 8 months, and start the deceleration action, slowly reducing themselves to a speed of less than 200 meters per second relative to the deep space star. On the 8-20-kilometer orbit of the empty star, it will be detected.

The whole process takes about a year.

During this period of time, after a long and difficult search, people finally found the first spy satellite from a deep space civilization on an orbit 17.6 kilometers away from Sedna.But unfortunately, people did not manage to capture it.

Just like the spy satellites launched by humans to the deep space star, these spy satellites from the deep space star are also equipped with a self-destruct system.After realizing that someone was trying to capture them, they immediately chose to self-destruct.

The explosion even nearly took the life of a soldier.Even if they escaped by chance, the Wu-1 spacecraft lost all its power and could only stand still and wait for help.Subsequent rescue spacecraft found only some metal fragments of the spy satellite.

These things were immediately taken into the laboratory by the treasured military experts for analysis, hoping to infer more information about the deep space civilization by analyzing the relevant data of these materials.

The search is always going on.I believe that it won't take too long before people will be able to find a second spy satellite.At that time, people will be more careful and try to bring back the complete satellite as much as possible.

Time passed quickly, and soon, the spy satellites reached the sky above the deep space star, and started to work quietly.The first batch of information about the deep space star was also sent back.

Deep Space Star and Sedna Star are both distant independent celestial bodies. Except for being smaller, the surface structure is almost the same as that of Sedna Star. Both are covered with a thick layer of torin, and all kinds of landforms are readily available. .

Just above the surface, spy satellites have photographed many buildings with very obvious artificial features.However, its number is much smaller than that of Sedna.

Looking at these creations of another civilization, people's hearts are full of wonderful feelings.

Under people's careful discrimination, the divisions of living areas, industrial areas, and military areas were identified one by one.As for the space target, it has not been searched.

"The creations of the deep space civilization are too few. Judging by our human standards, a cluster of this size is unlikely to create a weapon such as a long-range interstellar missile."

"There are two possibilities. One, they have a higher level of technology. Two, they actually have many creations, but they are hidden. They may be underground in the deep space star, or they may be in space, just like our Tinder Like a spaceship."

"If it's the second possibility, more of their creations should exist underground, and it's unlikely to be in space. Industrial clusters are huge things, as long as there is no technological gap, they must be like this. And if there are really There's no way our spy satellites can't miss a cluster of buildings on such a large scale."

This judgment has been recognized by the people.

"It should be underground. If their technological level is really high, they don't need to pretend to us."

This is the most desired result.It is best if the technological inheritance of the deep space civilization has been interrupted or lost, so that people don't have to worry about their technological development surpassing their own.

Zhao Changxing knocked on the table: "Let's make a further test."

"Yes."

In the plan, people will manipulate one of these spy satellites to keep it approaching the deep space star until it is destroyed or captured by the deep space civilization.

In this way, people can indirectly test out the ability of the defense system of the deep space civilization planet, and make the next step based on this.

Of course, this may lead to the leakage of one's own scientific and technological information, or being detected by the other side, just as one's own side is also searching for their spy satellites and trying to capture them.But Zhao Changxing believes that this price is worth it.Besides, it's just a spy satellite, even if it leaks again, how much can it leak?
The signal from Sedna has been sent at this moment.It will reach the spy satellite after a communication delay of more than 3 minutes.

After the delay, people saw that the picture displayed on the screen began to gradually become clear little by little.Obviously, the spy satellite is constantly shortening the distance between itself and the deep space star.

10 kilometers, 9.8 kilometers, 9.6 kilometers...

The distance reduction process has been going on for more than four days.When the distance was finally shortened to 6.25 kilometers, the picture disappeared.

Signal transmission interrupted.

"The satellite was destroyed or captured. I don't know if it blew itself up or not."

People sighed and immediately started further discussion.

Measuring the defensive capabilities of a planetary defense system can be calculated through a complex model.Now, people have obviously obtained some more critical data.

After inputting a series of data into the model, Xiao Xi came up with a conclusion the next moment.

"In order to break through the planetary defense system of the deep space star, the final speed of the interstellar missile needs to reach at least 29.21 kilometers per second."

"29.21 kilometers per second..."

This data makes people look at each other in blank dismay.

You must know that the fastest missiles launched by the deep space civilization to Star Sedna were only 25 kilometers per second when they reached the highest speed.

What is more noteworthy is that the results calculated by this model are presented in a probabilistic manner.Even if the missile can reach this speed, the probability of a single missile breaking through the defense net is only 31%.

Based on this probability calculation, the probability that five consecutive missiles will not be able to break through the defense network is 69% to the fifth power, or about 15.64%.Conversely, the probability of at least one hit is 84.36%.Zhao Changxing thinks this probability is an acceptable lower limit.

And the five long-range interstellar missiles are the maximum power people can use in retaliatory actions at this stage.

Any more and it wouldn't be realistic.

"However, our missiles are fully loaded, and the maximum speed can only reach 19 kilometers per second..."
