Navigating in the void of the universe is very boring, especially in areas outside of distant star systems. These areas are very empty and many stars appear to be very close. In fact, the distance to these star systems is calculated in light years. .

During long-term interstellar voyages, the psychological problems of astronauts are a very important topic. The alliance has even set up institutions such as the Institute of Space Psychology to study the psychological diseases that astronauts are prone to during space voyages.

On board the Explorer space cruiser, political commissar Zhang Handong, in addition to supervising the discipline of the captain and soldiers, also has an important responsibility: psychological counseling.

In order to alleviate the psychological problems of astronauts, not only the living facilities on the battleship are complete, but also the entertainment facilities are very complete.

Zhang Handong is playing space rugby with several soldiers. Space rugby is completely different from Blue Star ground rugby. Due to the microgravity environment of space, the space rugby gameplay is very weird. They use their strengthened bodies to collide crazily in the stadium. He even showed off his fighting techniques.

"Damn it, Commissioner Zhang, you are so shameless."

"A soldier never tires of deceit."

Zhang Handong kicked away a guy who was trying to grab the rugby ball and jumped toward the opponent's goal. However, the opponent's players were not vegetarians either. Two blue team members outflanked him.

"John, go on."

Zhang Handong made a fake move and threw the ball to another red team member, and the two blue team members who were outflanking him collided with Zhang Handong in an instant. If it were an ordinary person who collided like this, he might suffer serious fractures and serious injuries in an instant.

At this time, outside the stadium, there were cheering and shouting spectators and blue sky and white clouds. It was obvious that this was a holographic simulation environment, and only the players in the lounge nearby were real people.

However, the two teams playing fiercely on the field felt as if they were really in a space rugby field in the solar system.

Ma Wu, who had just come off his shift, also came outside the venue. Looking at Zhang Handong and others rolling and moving inside the venue, he smiled and shook his head. He sat on a chair nearby and turned on his holographic bracelet to read the news.

Fortunately, there is no delay in the Explorer's quantum communication system yet, and he can browse the alliance's internal news at any time.

[Mars Daily: Mars welcomes all Alliance citizens to settle down and buy property. Each person can get 100 square meters of housing for free, and can arrange a job and have an annual income of 100 million yuan tax-free for 5 years...]

[War and Peace Weekly: The Alliance Army welcomes citizens to actively join the army, defend the solar system, and march into the greater galaxy...]

[Oceania United News: Madagascar applied to the Alliance Council to become the first Nature Protected Country, and the Alliance Council has approved it. From April 12, Galaxy 2, Madagascar Natural Country will be officially included in the scope of Alliance management...]

"What are you looking at?" Zhang Handong wiped his sweat with a towel while talking.

"No, just browse the news about the alliance." Ma Wu continued to read the news.

After Zhang Handong sat down and took a sip of the nutrient solution, he looked at the time on his watch [12:21, April 4, 2018, Galaxy 2].

"Is Haibo commanding the battleship now?"

"Yes."

"Did you notice anything unusual?"

"Abnormal? Does Commissioner Zhang mean aliens?" Ma Wu raised his head and asked with a smile.

"Both." Zhang Handong put down the towel and water bottle, opened the holographic bracelet and prepared to record something.

"Everything is normal, but 11 asteroids with a diameter of more than 50 meters were discovered near the channel. The star map database has been updated, and the others have not been found." Ma Wu thought for a while and replied.

Zhang Handong was recording this information while looking through the database. He had the habit of writing a diary, and soon he had recorded a full page.

"Huh? Gravitational waves?"

"It should be caused by the recent testing of gravitational bombs at the Void Test Site. We are now about 370 astronomical units away from the Helic Planetary Fortress, and 346 astronomical units away from the Void Test Site. It is very normal to receive gravitational waves." Ma Wu explained.

Zhang Handong raised his eyebrows and continued writing in his diary.

"What's the status of our spacecraft's fuel and supplies reserves?"

"Everything is normal. If we reach the first cordon, I will look for some planets for supplies." Ma Wu replied.

…

Over time, the gravity bomb has been tested six times. After so many tests, the Gravity Research Institute has obtained a lot of data. Through further analysis and research of these data, An Shitong, Wang Wenhua and others have gained insights into the research on gravity. unprecedented development.

For example, they have successfully analyzed the principles of the strengthening and weakening of gravity. They have also discovered the super-light phenomenon under strong gravity and the low-light phenomenon under weak gravity.

These circumstances illustrate that the speed of light in the universe is not necessarily constant, especially in the early days of the universe when the gravitational intensity was higher than today. At that time, the speed of light should have been higher than 300,000 kilometers per second. If the universe continues to expand in the future, the speed of light may will slowly decrease.

Huang Haojie is also studying these theories to some extent. As for the beginning and end of the universe, Huang Haojie's view of the universe is [starting point (singularity) - big bang - red shift (expansion) - middle point (equilibrium point) - blue shift (shrinkage) - heat death collapse - end point (starting point)], this process is repeated in a cycle.

Of course, regardless of red shift or blue shift, human civilization has not yet reached the point where it is necessary to think about the destruction of the universe. After all, even if the universe is to be destroyed, it will only happen after hundreds of millions of years. It is better to take care of the things in the galaxy at hand.

The Gravity Research Institute has finalized and mass-produced gravity bombs with a magnitude of 1 AU, 5 AU, and 25 AU, and is currently developing 100 AU and 500 AU gravity bombs.

Gravity bombs with a magnitude of 100 AU and 25 AU were transformed into space mines and then hidden in asteroids. The Alliance planned to deploy a layer of space minefields in an area about 1,000 to 1,500 AU from the sun.

Then use gravity bombs of 25 astronomical units and 5 astronomical units to deploy a second layer of space minefields within a range of about 500 to 600 astronomical units from the sun.

The gravity bombs or gravity missiles equipped on battleships are on the order of 5 astronomical units and 1 astronomical unit.

Of course, since mines are to be laid, the early warning system must also have the ability to detect the opponent in advance. The Supreme Command decided to deploy the first layer of early warning satellites in an area about 1,500 to 1,600 astronomical units from the sun; in an area of ​​600 to 700 astronomical units, The second layer of early warning satellites is deployed; and the early warning satellites that were previously near the Oort cloud are the third layer of early warning satellite systems.

Minefields and early warning systems intersect in the outer layer of the solar system, forming the first line of defense of the solar system. Unless the opponent constantly uses large-scale legions to detect mines, it will be difficult to break into the Oort cloud border of the solar system. Even if It can rush in, and it is also a small fleet.

As long as the alien civilization is not a third-level or fourth-level civilization, and the human civilization is among the second-level civilization, it is unlikely to lose. Even if it is defeated, the worst thing is to escape on the civilization seed spacecraft. Now the first civilization seed spacecraft "Blue Planet" The "Shenzhou Chixian Ship" has been completed, and the "Shenzhou Chixian Ship" is under construction.

In other words, human civilization can temporarily let go and carry out the work of exploring the universe.
