Chapter 348 Trek, Probability Card
A copy, in "Legend of the Galaxy".

Feitian, which entered the black matter belt between the spiral arms, is in the state of automatic navigation.

It is estimated that after 300 years (spaceship time), it will cross this distance of 500 light years and arrive at the opposite second spiral arm.

Therefore, Yun Xinghe and others lying in the dormant cabin set a dormancy time of 300 years.

However, the plan did not go as smoothly as expected.

At the 155th year of dormancy, Yun Xinghe woke up amidst a violent shaking.

As soon as he opened his eyes, a large number of objects floated in front of his eyes - there were parts, pipes and three-eyed people the size of peanuts.

Hundreds of three-eyed people who worked together to open his dormant cabin were flying around between the floor and ceiling of the dormant room, flying all over the sky, "bang bang bang" hitting back and forth like marbles.

"what happened?"

Yun Xinghe, who had a splitting headache for a while, recovered a small amount of memory. After removing the fixing belt on his body, he suddenly lightened, and a thrust came from his buttocks, and Yun Xinghe suddenly ejected from the dormant compartment. The scenery is like a bucket of stars moving, and nothing can be distinguished.

"boom!"

There was a sharp pain in the waist, and he hit the ceiling heavily.

"boom!"

The head banged violently against a protruding device on the floor, causing a mild concussion.

"Alert! Alert!"

"The spaceship has entered a high-speed spiral state, and the state is close to being out of control!"

"Start attitude control engine, trying to recover!"

"The speed of rotation has begun to decrease, and it is expected to return to its normal posture in 30 minutes..."

The notification sound of the spaceship brain kept coming from the ear.

30 minute later.

The attitude of the spacecraft finally returned to normal.

Yun Xinghe, who was covered in scars, left the dormant room and opened the hatch of the medical room next to him.

After briefly treating the wounds on his body in the medical cabin, Yun Xinghe lay down in the memory recovery machine and restored his nearly 30% lost memory.

The main control hall of the bridge.

"Xiao Kong, what happened, why did I wake up early?"

"Captain, we have entered an unknown dark area. There are space turbulence and material vortices that cannot be measured by instruments. The mysterious dark energy field has affected the normal working status of a large number of spacecraft equipment. Xiaokong can't judge the orientation of the spacecraft now." , unable to confirm whether the spacecraft is still on the set route.”

"what?"

Yun Xinghe was taken aback, and quickly asked: "You mean Feitian, has it lost its way?"

"Yes, Captain, the spaceship is in a dark space."

Yun Xinghe raised his head and looked out of the porthole. The blackness like thick ink could swallow even light, which made his heart sink.

Then he shook his head again and again: "This is impossible, at least the interstellar gyroscope of the spacecraft can still be used, we can't get lost!"

The interstellar gyroscope is designed based on the gravitational waves generated by large gravitational objects, pointing to the massive black hole at the center of the galaxy. As long as this black hole does not disappear, Feitian cannot get lost, just like a compass will always point north and south.

"Captain, there is an anti-gravity field that Xiaokong can't explain in this space. Under the influence of this anti-gravity field, the gyroscope cannot work, and there is no starlight outside the spacecraft. Captain, we are trapped!"

Boom~
Yun Xinghe's heart skipped a beat, he got lost, Fei Tian really got lost.

"Then... what should we do next, Xiao Kong?"

Yun Xinghe was in a bit of a mess, and he didn't know what measures to take.

"Before entering this area, Xiaokong made some observations. The thickness of this black matter belt is about 2 light-years, but the length is more than 2000 light-years, and the height is more than 300 light-years. According to the calculation of probability, if you want to get out of this area A belt of black matter, no matter which direction you choose, the probability of successful escape is very low, and due to the influence of the strange matter vortex, the resistance of the spacecraft to travel is very high. If the spacecraft still cannot escape before the acceleration medium runs out, we will forever Stay in this material belt."

"How far is the remaining acceleration medium of Feitian enough to sail?" Yun Xinghe asked.

"8 light years." Xiaokong said after a calculation.

"Can't the dark matter outside the spacecraft be collected as the energy source for the spacecraft?"

"No, this substance is smaller than an electron and cannot participate in fusion reactions in a substance reactor."

There are many particles smaller than neutrons and protons in the universe, such as neutrinos, quarks, bosons, etc. Some of these particles have mass attributes, and some have energy attributes, but because they are too small, these particles are not only difficult to capture , is not yet available.

However, the three-eyed man has certain technical capabilities and can use some tiny particles, but he can't achieve the level of using these tiny particles as energy.

"Then... what is the probability of finding the shortest escape route?"

It can be seen that this belt of black matter is only 2 light-years thick, similar to the Feitian in a "flat belt", as long as it finds the right direction, it only needs to fly a distance of one or two light-years at most to achieve separation, but it must be in In the darkness without any frame of reference, it is really difficult to find the shortest "straight line".

"The probability is less than one in 13.5, and the probability can only be calculated in a cone-shaped range. The probability of leaving the trek area within two light-years is about 27%; the probability of leaving within three light-years is about 36%; within five light-years Disengagement, about [-] percent."

Don't think that this probability is very high. Based on the voyage of Feitian at most 8 light years, no matter how many light years it leaves, the number of times Feitian can try is not many.

Yun Xinghe asked Xiaokong to simulate a variety of traversing plans, and found the safest plan, and the overall success rate was hard to exceed 50%.

It can be said that this time, the Feitian is more of a disaster than a blessing.

"Probability, probability card... Hey, there is a way!"

Thinking of one thing, Yun Xinghe's brain flashed, and he immediately had an idea.

"Grandpa, grandpa! I'm in trouble!"

In his head, he immediately shouted.

……

Zhou Ming in reality.

After hearing Yun Xinghe's call, he was taken aback for a moment. Why did this kid end his sleep so quickly? Did he arrive at his destination?

After asking, I found out that the Feitian was lost in the middle of its flight.

"Grandpa, didn't you say that you have probability cards in your hand? Hurry up and give me a few. Without probability cards, Feitian may be doomed!" Yun Xinghe said anxiously.

"I can give it to you, but most of the probability cards in my hand are [1% probability cards], which can only increase the probability by 1% after use. There is also a better [10% probability card], but after using it After that, there will be no more.”

Zhou Ming said that in the experience of the last game, he let Luo Aixing try a [1% probability card], but it had no obvious effect.

"1%... If you use more than one card at a time, can the effects be superimposed?" Yun Xinghe asked again.

"Yes, but it's not additive stacking, but multiplicative stacking. Additive stacking will only happen when you only use one card." Zhou Ming also asked the system about this question. The system's suggestion is: buy ten [1% probability cards], it is better to buy one [10% probability card], even if the latter is ten times more expensive.

"Then I'll ask Xiaokong to see if it has a better strategy, given these probability cards."

……

"Increase probability?"

"The probability is increased by 1% on the original basis... Captain, it is impossible to artificially increase or decrease the probability. If it can be artificially increased, the entire probability model will undergo earth-shaking changes! Although 1% is very small, this 1% , in a special probability model, the probability multiplication effect can occur, and the probability of Feitian leaving the trek area will also be greatly increased!"

Xiaokong said, this is actually the same as gambling. The real God of Gamblers wins not by the 50% probability, but by the 50% other than the 1%. As long as you catch this 1%, some kind of Under certain circumstances, 1% can become 100%.

"You can redesign a model, add the 1% I said, and see if you can increase the probability of the spaceship's escape to more than 80%,"

Five seconds later.

The new model was calculated, and Xiaokong said: "According to this model, it only needs to increase the probability of 1% four times, so that the escape probability of Feitian can be increased to 67%, and 23% of the acceleration medium can be retained."

Increase by 1% four times, it can be increased to 67%, so powerful?
"What if we add another 10%? Can the escape probability be increased to 80%?" Yun Xinghe asked again.

"Not only 80%, but can reach 96%." After only a few seconds of calculation, Xiaokong said again.

"That's good! Let's escape according to this plan, Xiaokong, open the star map, and I will choose the route." After asking the old man to transfer the probability card to his mind, Yun Xinghe said.

"Captain, are you sure you want to do this? This is against the laws of probability. Once you make a mistake, the probability of Feitian being lost forever is more than 80%." Xiaokong was taken aback and immediately reminded.

"Open the star map, don't question your captain." Yun Xinghe said with a straight face.

"Okay." Xiaokong did as he said.

A spherical light curtain appeared in the air. Against the dark background, a star map full of white probability lines appeared in front of Yun Xinghe. On each white line, a set of numbers was marked, and a set of numbers was accurate to the decimal point. Probability numbers for the last 100 digits.

Because the orientation of Feitian is uncertain, and the speed of Feitian is affected by the material vortex, all the initial speed is lost, so the probability numbers on these dense lines are all equal.

"1% probability card, use it!"

Yun Xinghe muttered in his mind, and used up a 1% probability card.

As soon as he used it, Yun Xinghe's vision immediately changed!

Some of the dense white equal probability lines in the star map have changed in color.

From white to yellow.

And above these yellow lines, the numbers representing the probability have increased from 0.0000142% to 0.10000142%.

The numbers on other lines, especially the numbers on the white line, due to the increase of this external variable, under the law that the total probability must not exceed 1, these numbers are reduced by thousands of times... because there are 99 yellow lines in total.

This means that in this model, because of the 1% increase in probability, Yun Xinghe excluded tens of thousands of low-probability options at one time except for the yellow line.

With the remaining 99 options, the probability of choosing the right route is equivalent to an increase of nearly 0.0000142 times on the basis of 1%!
This shows the horror of probability cards.

Especially in an absolutely fair model, 1% of external variables is equivalent to an increase of tens of thousands of times of inequity.

"Xiao Kong, load this route."

In the field of vision that Zhinao Xiaokong couldn't see, Yun Xinghe chose the middle one from the 99 yellow lines.

"Yes, Captain!"

After loading the route, Feitian stubbornly sailed forward along the route in the dark belt of black matter.

　From today to the end of the month, three shifts every day, I hope you will forgive me...
