The last human in the universe

Chapter 156 Relativistic Effects

If before this, people had some hesitation and doubts about whether to pay such a huge price and so many resources to fight, then now there is nothing.

Doing everything and seeking to improve strength at all costs is something that human civilization must do.On the road of seeking the survival of civilization, there must be no slack at all, and every opportunity must be seized.

Survival turned out to be really not an easy task.

After reaching a complete consensus internally, Zhao Changxing's order was issued again.This time, there are more technical workers, engineers, scientists, and corresponding support staff, and those who provide social services for the above-mentioned people, and a total of about 100 million people have been awakened.

At this moment, the number of conscious personnel in the entire Yuanhang spacecraft has almost reached 200 million.And this has already exceeded the carrying limit of the three "rollers" with gravity inside the Yuanhang spacecraft.Moreover, the consumption of various sustaining materials has far exceeded expectations.

This is also one of the costs.

With the concerted efforts of the people, a large number of precious resources were transported out of the warehouse, and then under the busyness of engineers and workers, they were turned into parts one by one, and then assembled to become one machine after another. A piece of scientific equipment.

——This is of course done with the assistance of many robots and many automated equipment.What Zhao Changxing has always insisted on is that tasks that can be completed by robots and automated equipment will never use manual labor.Only in this way can the efficiency be improved as much as possible.

It took a total of more than a year for the upgrade of the original neutrino telescope inside and the construction of four new neutrino telescopes located in different parts of the Yuanhang spacecraft.Therefore, the Yuanhang spacecraft stayed in this piece of war relics. Along with the "mines" that may or may not be in space, they sailed for about 9352 miles in a direction slightly away from the Lakai 100 star. million kilometers away.

At this moment, after a long process of installation and debugging, the muon detection can finally start.

Located behind a thick anti-radiation layer, in a pure black environment that is hardly disturbed by any kind of radiation, there is a "big tank" filled with hundreds of thousands of tons of ultra-pure water.

This large tank is in an extremely stable state, and because of this, there is hardly any flow of ultrapure water inside it.They are as quiet as a solid piece.

At this moment, a particle silently penetrated the thick radiation protection layer and reached the ultrapure water.In the process of penetrating these pure waters, it coincidentally collided with a smaller particle in a water molecule.

This is indeed a coincidence, and a coincidence with a very low probability.Because at the same time, there are more than a million particles passing through these pure waters together.But of these, only it has collided with the particles that make up these ultrapure waters.

This collision produced other subatomic particles, including some photons.

Once generated, the photons travel through the medium at the speed of light and are detected by numerous extremely sensitive photomultiplier tubes mounted around the perimeter of the tank.

These signals constitute an event, which is then displayed on the computer screen.

"Professor Zhuang, we have observed the 1522nd event."

At this moment, Zhuang Yunwei's mood was slightly depressed.

A total of five neutrino telescopes have indeed observed a large number of muon impact events during the period after they were put into operation.But all of these incidents were finally confirmed to be from the Yuanhang spacecraft.

Although people have shielded the neutrino telescopes as much as possible in the direction of the Yuanhang spacecraft, but they really can't stand the excessive penetration of muon particles.

On the earth, in the rock formation environment hundreds of meters below, it is still impossible to completely isolate the penetration of muons, let alone in space.

"Continue to analyze."

Zhuang Yunwei ordered casually, but didn't take this incident too seriously.But soon, with the exclamation of his researcher, Zhuang Yunwei suddenly raised his heart.

"Direction, 36°22′19″, the particles in this incident did not come from the Yuanhang spacecraft! "

"Let me see!"

Zhuang Yunwei almost threw himself on the computer screen.After seeing clearly the data displayed on the screen, he couldn't help showing joy on his face.

The entire human civilization has invested so much resources in this project, suppressed so much bets, and shouldered the expectations of so many people. As the general manager of the project, how could Zhuang Yunwei not be under pressure?

God knows how he survived this period of time!

Now, has it finally come to fruition?
"Continue to analyze, continue to analyze..."

He murmured an order, turned around and picked up his phone.

He wanted to report to Zhao Changxing immediately.

After a more detailed analysis of the data generated by this impact event, people roughly determined the direction of arrival of the particle, and confirmed the upper limit of the farthest distance through the energy level of the particle.

The half-life of muons is only 2.2 microseconds. Calculated according to this time, throughout their lifetime, even if their speed is the speed of light, they can only travel an average distance of about 300 meters.

But muons are usually very energetic, and their speed is very close to the speed of light.On them, the relativistic effect is extremely obvious.In this case, they can transmit far beyond 300 meters.

The higher their energy, the faster the speed, the more obvious the relativistic effect, and the farther the distance transmitted.Then, as long as the energy level of the particle can be measured and its energy determined, the upper and lower limits of the distance can be determined.

Now, it can actually be found by conducting a detailed search of an area within a certain direction and within a certain distance.

A combat spacecraft was ordered to set off and went to a place about 47.6 kilometers away from the Yuanhang spacecraft.

The range that needs to be manually searched in detail has a diameter of about 6 kilometers and a total volume of about 113 cubic kilometers.

In such a small place, you don't need a lot of manpower and equipment to search the bottom of the sky.

Sure enough, after about an hour, a picture was transmitted to the command room.

Zhao Changxing saw a piece of "wreckage" about 2 meters in length and more than one meter in width, which was generally L-shaped.

This is not a gravity bomb.

"It doesn't matter. This at least proves that our direction is correct. Keep searching. As long as there is a gravity bomb, we can always find it."

As Zhao Changxing expected, this day is not too far away.After 7 more incidents, after finally searching for the wreckage, for the eighth time, the fighters performing the search mission sent a picture of something very similar to the previous gravity bomb at a distance of about 326 million kilometers from the Yuanhang spacecraft. back.

"This is a gravity bomb, you can't go wrong!"

At this moment, everyone in the control room was in high spirits.

"Order, Spaceship 56 stays where it is, don't approach the target any more!"

Things like gravity bombs are extremely dangerous and extremely unstable.Although it is almost certain that they have lost the ability to "actively search for targets and actively approach targets", according to experience, certain collisions can still detonate them.

To capture this kind of thing requires special equipment.Moreover, it may not be successful for the first time, and may require many times of exploration and experimentation.

This time, it was a small unmanned spacecraft that was sent to capture it.The specific facility used to capture it is a special box.

The inside of this case is filled with soft, specially made padding.This filling can greatly prolong the release time of gravity applied to the contents.

This is how people try to capture it without detonating it.

Under the slightly nervous gaze of the people, the unmanned spacecraft stretched out its long mechanical arm, opened the large box that was almost five meters long, and then slowly covered it.

The moment the inner filling touched it, everyone's hearts were lifted.

It seems that in the next second, the video screen will disappear and turn into pure black—that means the facility has been destroyed, that is to say, the gravity bomb has been detonated.

But that didn't happen.Nothing unusual happened until the big box was finally closed and the gravity bomb was completely covered by the soft padding.

"it is good!"

There was warm applause in the control room.

After that, it was captured in the cabin of the unmanned spaceship and fixed.After that, the unmanned spacecraft began to accelerate extremely slowly compared to its performance.

It is only 3 millimeters per square second, which is only a little faster than the acceleration of the Yuanhang spacecraft with a mass of more than 1000 billion tons.

"Is the spaceship used to store these gravity bombs ready?"

Zhao Changxing looked at a civilized leader.

"It's ready. The space shuttle numbered J3 has completed its internal modification and has moved to a place 10 kilometers away from the Yuanhang spacecraft."

It is obviously impossible for something so dangerous and out of control to a certain extent to be stored in the Yuanhang spacecraft.

Zhao Changxing didn't want to wake up one day and the whole spaceship was crushed into an iron ball.

The plan formulated by the people is to store all these gravity bombs in a special space shuttle, and then connect it to the Yuanvoy spacecraft through a rope, and let the Yuanvoy spacecraft pull it forward.

Materials of the kind used to make space elevator cables could be up to the task.

In this way, even if those gravity bombs exploded unfortunately, it would not have any impact on the Yuanhang spacecraft itself.
