MTL - Super Battleship Reborn-Chapter 40 Gravitational lens

Chapter 40 The method of gravitational lensing to destroy enemy detectors is very simple. It is still the kind of ejection device used to launch interstellar missiles, except that the interstellar missiles have been replaced with conventional high-explosive ammunition. A little wasteful.

After Xu calculated the orbit, Xiao Yu aimed at the instrument and fired the ammunition.

Seventy seconds later, the high-explosive ammunition crossed a distance of several thousand kilometers, and met the detection instrument of the alien civilization head-on. Then, the pre-set detonation device was activated, the ammunition was detonated, and a flare burst in the air. The detection instrument is like a kite with a broken line. It doesn't know where to go.

Time fought, it became more and more urgent. Although Xiao Yu was not found with this instrument, Xiao Yu was not sure whether the next instrument would find himself before he discovered it. It's like hanging a sharp sword on top of one's head at any time, which may be cut off at any time.

This feeling of being threatened at any time is very bad.

文明 Both civilizations in the dark universe are trying to find each other first. Whoever finds the other party first has the greatest advantage. In the following two major civilizations, the winning rate can be increased by at least 30 percentage points.

The current situation is not optimistic.

The other party has found an effective method, but Xiao Yu has not found his own method.

I released some detectors to roam randomly in space. The other party could use it, but Xiao Yu couldn't. The reason is simple. To achieve effective signal coverage and adapt to a large search area, God knows how many detectors are needed. The other party has its own planet. With its own planet as the material base, the other party can get unlimited materials and can create so many detectors, but Xiao Yu has only one fleet. Xiao Yu's materials are limited and cannot be compared with each other.

Xiao Yu must find another way to confront the other party, otherwise, Xiao Yu can only pray for his good luck so that he will not be discovered by the other party. But, can luck be better for one year, ten years, fifty years, one hundred years?

There are thousands of years to reach the Tianyuan Four Galaxy. Moreover, Xiao Yu also cannot guarantee that after reaching the Tianyuan Four-Star System, he will certainly be able to defeat the opponent.

Xiao Yu continued to make calculations. Under Chen Mo's attention, he suppressed his self-violence and abandonment, and patiently made calculations.

I don't know how many times I failed, nor how much time has passed. Xiao Yu only knew that during this period, he had destroyed at least ten enemy detectors.

Gradually, Xiao Yu's eyes lit up.

Xiao Xiaoyu thought of a method. This method has passed the 40,000 detection obstacles set by Xiao Yu. This proves that this plan is feasible. Moreover, this plan does not have a certain amount of luck like the other party ’s means, but as long as it takes a certain amount of time, Xiao Yu can definitely find out the other party.

It is like launching a large number of detectors randomly looking for this method. The other party can use it. Xiao Yu cannot use it. In the same way, this method can be used by Xiao Yu but the other party cannot.

That is, a gravitational lens.

The concept of a gravitational lens was first proposed and predicted by Einstein, the greatest scientist in human history. In simple terms, a gravitational lens means that when a star light passes around a massive star, the light that originally traveled in a straight line will be The mass star's gravitational pull causes it to appear curved as if the position of the original star was slightly shifted.

Xiao Xiaoyu knows that this alien civilization's planet is more massive than Earth's. It is certain that gravitational lensing will also occur around the planet.

On a cosmic scale, however, the planet ’s mass is still too small. The effect of the gravitational lens may be minimal, which means that a very high-precision instrument is needed to observe which direction the gravitational lens phenomenon has occurred.

The next thing is very simple. As long as Xiao Yu observes which direction the gravitational lens phenomenon occurs, and then through a series of precise calculations, the position of the opponent can be calculated.

This is also the reason why Xiao Yu can use it, but the other party can't. Although Xiao Yu's fleet has a total mass of tens of millions of tons, compared with a planet, it can be regarded as an ant that can be ignored. Observing the gravitational lens of a planet is so difficult, let alone observing the gravitational lens of Xiao Yu's fleet.

At least, Xiao Yu estimates that a civilization that is thousands of years ahead of its own technology may be observed, but this alien civilization certainly does not have this ability.

In the sky, the position of the original star, recorded in Xiao Yu's Qin Ying's sky, has been recorded. The offset position can be obtained from the current observation. What Xiao Yu has to do is simply to re-observe all visible stars in the whole celestial domain, and then compare it with the data in the Qin Ying Chuangqiang to see where the starlight has shifted.

But it is simple to say, it is not easy to do. This requires extremely high-precision observation instruments and a huge amount of data calculations.

Xiao Xiaoyu prepared for half a year to do this.

Countless data were collected in the central computer, and after the central computer calculated, the results were compared with the original data in the Qin Ying Cangqin Record, and one star after another was excluded by Xiao Yu.

Every star that has been eliminated proves that there is no enemy in this direction. Gradually, Xiao Yu's search scope became smaller and smaller.

The search range of 360 degrees in the whole sky domain has been narrowed by Xiao Yu to less than half a day in the range of 160 degrees in the past three months.

The next star to be measured is a star located in Canis Major, which humans usually call the military city one.

Military city one is five hundred light-years away from the sun. Prior to this, humans did not have detailed data on military city one. However, when editing the sky record of Qun Ying, Xiao Yu measured military city one and collected its mass and volume , Spectrum type and other data.

As soon as General Jiang observed again, Xiao Yu began to analyze its various data and then compared it with the original data.

"Huh?" During the comparison, Xiao Yu found a very slight gap.

After removing the error caused by the movement of his own position, the position of Military City One is shifted a little bit from the original position. Its right ascension and declination are about 19.9 million degrees higher than the original position. The offset.

Xiao Xiaoyu immediately captured this message and immediately started the second review.

The results of the review soon came out, and the conclusions reached remained unchanged. In military market one, an unexplained slight shift did occur.

排除 After ruling out all possibilities, the alien planet was hidden somewhere between itself and the military city, becoming the only explanation.

Xiao Yu was so excited that he immediately took the military city one as the center and measured the stars around the celestial sphere. The results showed that the stars around the military city one had sizes. Uneven offset.

"Well, I finally found you." Xiao Yu muttered, his heart was extremely excited.

With this data, Xiao Yu calculated the specific position of the alien planet in only thirty seconds.

They are located in the direction of the big dog, about 32 million kilometers from Xiao Yu.

"Come without indecent assault, you fire detectors to come to me, and I will fire hydrogen bombs back to you ... wait and see!"

Xiao Xiaoyu was immediately ready to launch and launched a large-equivalent hydrogen bomb. It is expected that after three months, the hydrogen bomb will reach a predetermined position and then explode.

After more than a year of searching, Xiao Yu found the other party. The anger that had been suppressed for a year erupted instantly, and Xiao Yu couldn't wait to see the picture of the hydrogen bomb exploding, with a bit of resentment.

But Xiao Yu's behavior is still under intellectual control. Xiao Yu intentionally launched the second batch of hydrogen bombs ten days after the launch of the first hydrogen bomb. There were a total of twenty hydrogen bombs.

After five days of silence, Xiao Yu fired a third batch of twelve hydrogen bombs.

Xiao Yu deliberately made his launch time and launch number irregular. In this way, the other party could not organize effective interception methods. They would become bow-struck birds, always worried about the attack of hydrogen bombs, and always lived in the shadow of hydrogen bombs. under. Because they never know, UU reads www. uukanshu.com When will the next hydrogen bomb arrive.

"Enjoy the hydrogen bomb dinner, bastards!" Xiao Yu thought fiercely.

In three months, Xiao Yu fired a total of about 300 hydrogen bombs. Of these three hundred hydrogen bombs, even if only thirty could explode, that would also bring an extremely powerful radiation disaster to that planet.

Xiao Yu even made an estimate that if the equivalent equivalent of a hydrogen bomb explodes above the earth, the various hazards caused by the radiation hazards caused by radiation hazards, infant deformities, etc., will cause human populations to Seven billion people, fell to less than 100 million.

This basically means that the dead are extinct. Of course, Xiao Yu didn't know the physical structure and anti-radiation level of these aliens, but judging from their panic response last time, they were also very afraid of these hydrogen bombs.

"Fry it, fry it." It was time for the planned explosion, Xiao Yu's eyes lighted, and he stared nervously at the direction of the planet in the calculation.

In the distance, a burst of faint light burst suddenly, and its brightness was not even comparable to some distant and dim stars. But that planet is more than 30 million kilometers away from Xiao Yu, and even so far away, the light it emits can still be observed by Xiao Yu, and its intensity can be imagined.

Xiao Xiaoyu's heart was excited, and he immediately calculated it.

The calculation results show that this burst of fire is the first hydrogen bomb launched by Xiao Yu!

Under the light of this burst of fire, Xiao Yu also observed the faint, bright light reflected by the planet.

This shows that everything is as expected by Xiao Yu! Their planet is indeed in that position.
