Time was also a wonderful unit in the universe.
It didn't really exist and couldn't be observed. According to the current research of the Human Alliance, it only existed as a unit of a form of material movement sequence in the human perception world.
For Zhao Xiaofeng, the clock was ticking.
As he endured the immense pain, he had to deal with the sudden incidents reported by Tomcat.
"Captain, we have already slowed down by half the distance, and we are about 14 million kilometers away from Earth! It would take more than 11 hours to arrive!”
This was Tomcat's regular report!
Because the spacecraft was decelerating, it only took 30 minutes to complete half of the scheduled flight. The remaining half would take more than 11 hours.
"Three million kilometers ahead, a small planet with a diameter of 500 kilometers suddenly deviated from its original orbit due to unknown reasons. After calculation, a certain trajectory overlapped with the trajectory of my spacecraft. The probability of collision is three in a billion!”
This kind of situation belonged to the category of sudden events. The captain needed to give reasonable suggestions based on his experience.
"Mobilize four binoculars to track and observe! If the probability of a collision due to orbital overlap exceeds one in a thousand within a distance of 500,000 kilometers, immediately activate the main cannon to shatter it!”
Although the probability of three in a billion was very small, as the relative motion changed, the probability of collision could become larger or smaller.
This required the captain to make reasonable arrangements based on his experience and the energy reserves of the spaceship.
Because the main cannon needed a few seconds to warm up, Zhao Xiaofeng calculated the safe distance under the relative speed in his heart and made the most radical choice.
There were only 700 tons of fusion fuel on the spacecraft, of which more than 200 tons were needed to decelerate.
The minimum amount of energy needed to deviate an asteroid with a diameter of 500 kilometers from its orbit would require more than 20 tons of fuel.
Even though he speculated that the enemies on Earth weren't technologically advanced, Zhao Xiaofeng wouldn't be careless. He would try his best to save fuel to counter the potential risks.
" Five million kilometers below us, there are about four asteroids less than fifty meters in diameter that might meet us! Captain, what should we do?”
Tomcat continued asking for instructions.
Even if it was a 50-meter diameter asteroid, with its speed and the Galaxy's speed, the kinetic energy generated from the collision would be a huge disaster for the spacecraft!
This kind of miniature asteroid was one of the main problems that interstellar travel often encountered.
This was because such asteroids, due to their relatively small mass, did not require much gravity and could be captured at close range.
And the Galaxy was a huge object that weighed tens of millions of tons. The moving mass produced at such a high speed was huge.
The greater the mass, the greater the gravitational force it exerted on other matter.
Therefore, at close range, when the spaceship was traveling at high speed, those planets with very small mass would be pulled by gravity like moths to a flame, flying into the embrace of the Galaxy spaceship.
This was undoubtedly a very dangerous thing for the spaceship.
Obviously, such a small planet was as annoying as a fly.
However, there were too many such small planets in the universe. They could be matter that had separated from another planet, or they could be celestial bodies formed by cosmic dust over a long period of time.
Using the spacecraft's main cannon to attack, even with the smallest energy output, was a huge waste of fuel!
"Activate the obstacle clearing airship to open up a path for the flying ship!”
"Yes, sir!" Tomcat pressed a button.
Galaxy's belly slowly opened, releasing a small fusion engine airship.
The Obstacle Clearing Airship was more than 50 meters long and had a cylindrical structure. It looked like a huge stick with two wings!
With the power provided by its small engine, the ship quickly flew 500 km above the Galaxy, maintaining a parallel flight with the ship.
"Tomcat, activate the main spacecraft's filter!”Zhao Xiaofeng ordered.
The Obstacle-Clearing Spaceship was actually a huge aerial that could fly. It was not equipped with any weapons!
They emitted a strong magnetic field within a certain range to shield (offset) the impact of these asteroids on the spacecraft's own moving mass.
Of course, this strong magnetic field would also interfere with the instruments on the spaceship, so they had to activate the filter to reduce the impact on the spaceship.
This was the best way for the Human Alliance to deal with the miniature planets after learning from countless spaceship crashes.
In the universe, there were countless such small planets in the solar system!
If they did not find a way to deal with them but relied on weapons to bombard them, they would run out of ammunition and food during the long interstellar voyage no matter how much fuel they carried!
