The countdown to three months has been made before the exploration of the Centaurus Alpha Galaxy.

The final preparation stage of the Future spacecraft is underway in an orderly manner.

At this time, it had been five years since the Earth's Eye left the solar system.

At the Pacific Base of the Interstellar Exploration Alliance, the Earth's Eye Command Center.

Nai Chen was discussing the latest situation of Earth's Eye with project team members such as Durunik.

"According to the flight speed, the Earth's Eye is about 0.15 light-years away from Alpha Centaurus and Alpha Centaurus." Durunik unfolded the route model of the Earth's Eye on his computer.

"The Earth's Eyes should have started to implement the slowdown plan." Yuan Shichen added a dynamic simulation effect to the model in his speech.

"I hope the Earth's Eye is lucky enough, otherwise it will only travel around the Alpha Centauri system." Durunik shrugged.

The deceleration plan of Earth's Eye is actually not complicated, and it is even a bit simple and crude.

In fact, it's more like a hodgepodge bundled slowdown scheme.

As early as two months ago, the Earth's Pupil had already opened another set of nano-light sails. This set of nano-light sails is much larger than the area of ​​the light sail when it sets off.

Its diameter reaches 300 meters and its area is more than 70,000 square meters.

The photon reflection direction of this set of light sails is the opposite of when starting, and it will play three important roles in the deceleration stage.

The first function is to use the reverse thrust force of the light energy of the alpha star a and b in Centaurus to slow down.

The Earth's Pupil Project Team used computers to build models to calculate:

If it is a 70,000 square meters of light sail, a thrust of about 340n can be obtained based on the intensity of sunlight received on the earth.

The mass of the Earth's Eye is 10.1kg, so it will get an acceleration of -34 meters/sec^2.

The flight speed of the Earth's Pupil is calculated at 84% of the speed of light (the speed is deteriorated during flight), which is about 252,000,000 meters per second.

If you want to reduce the speed of the Earth's Eye to a level that is enough to capture the gravity of the Alpha Centaurus and Alpha Centaurus, it will take about 7.41 million seconds, which is almost 85 days.

However, this is only a theoretical result, because the light intensity actually obtained in the Centauri Alpha galaxy will vary greatly with distance. To put it bluntly, in the early stages when the reverse nanolight sail was opened, the light intensity that the nanolight sail could obtain was very weak.

The second function, which sounds more rough. Like the solar system, billions of years ago, during the supernova explosion of stars in the Alpha Centaurus, a huge amount of dust would be spread around the galaxy. When leaving the solar system, the light sail of the Earth's pupil should be closed as much as possible to avoid collisions with these cosmic dust and single atoms.

However, the situation is just the opposite now. The nano-light sail of the Earth's Eye looks like an arrogant ancient general shouting: "Who dares to block my way!"

It will use every collision with various tiny particles (mainly hydrogen, helium, oxygen, etc.) to reduce its speed.

By the way, it will pose a threat. Large enough interstellar dust needs to be avoided. (It has been mentioned before that in the universe, there is very little "large enough" dust. The probability of their encounter with a spacecraft is estimated to be only one in 100,000 [50 zeros] 00,000.)

Of course, the actual slowing effect of this solution is difficult to predict. Who can know how many tiny particles of hatred will be drawn along the way? There is a big error in this.

The direction of the light sail can be fine-tuned to ensure that there is no major deviation in the flight direction.

What if the light sail is damaged?

If it is broken, it will be broken. Anyway, the Earth's Eye does not intend to return to the Earth, as long as its subject is not damaged.

The third function is that the light sail will also collect and store solar energy. By the way, it should not be called solar energy here, but Centaur energy, abbreviated as "horse energy".

The Earth's Pupil is different from the nanospacecraft of Mr. Hawking. It is a real guy's photon thruster, which will be the killer weapon of the final deceleration stage of the Earth's Pupil. After approaching the target area, the photon thruster will use the stored "horse energy" to complete an efficient "photon jet" to achieve the final deceleration effect.

These slowdown plans formulated by the extraterrestrial civilization project team were simulated and calculated, and had a success rate of only 60%.

Well, if all the above deceleration methods are ineffective, the poor Earth Eye can only travel around the Alpha Centauri system, and perhaps it will continue its interstellar journey and fly to the distant deep space of the universe.

However, the speed of the Earth's Eye should be greatly reduced at this time, so it will have relatively plenty of time to peek into the secrets inside the Alpha galaxy of Centaurus.

What made the Earth Eye Project Team feel very embarrassing was that at this time, the Earth Eye was fighting alone in the distant Alpha Centauri system, but they couldn't help at all.

Even the news of whether the Earth's Eye can successfully slow down in the end will not be known within five years.

"Don't think too much, let's wish the Earth's Eyes good luck!" Yuan Shichen said with a smile and patted Durunik's shoulder.

"If you fly towards Earth's Eyes on the Future, you can receive the signal sent back by Earth's Eyes in advance during the flight." Durunik said with some envy, because not long ago, he had confirmed that he had not finally become an astronaut in the exploration of the Alpha Galaxy of Centauri.

"Don't feel sorry, the earth depends on you, just wait for our good news on the earth." Harashi Chen comforted Durunik and said, "And, this trip is very risky, and many things are unpredictable, maybe we will never again."

"Please, don't say that. Just take a few more sleeps, have more dreams, and then return to Earth and become a great hero." Durunik interrupted Yuan Shichen's words.

Yuan Shichen's lips raised, and he looked at Durunik with a meaningful smile.

"In twenty or thirty years, if I could return to the earth smoothly, what would I look like at that time, what would my relatives and friends look like, and what would the earth look like?"

Yuan Shichen suddenly thought of the above questions.

General Relativity believes that if you fly at a speed close to the speed of light in an artificial black hole powered spacecraft, time will slow down and your aging speed will be much smaller than your family and friends on Earth.

Coupled with the impact of long-term dormancy in the hibernation warehouse during interstellar travel, your aging rate will further slow down.
