The village-level spacecraft continued to accelerate, reaching three times the speed of light before stopping.
Three times the speed of light is the highest speed that Xiao Yu can currently achieve.
Today, fifty years later, the radius of the four-dimensional barrier has shrunk from 10 billion kilometers to 7.5 billion kilometers. This means that starting from the center of the galaxy, at the speed of this village-class spacecraft, it only needs two
You can sail this long distance in half an hour.
The method of curvature drive is different from that of conventional navigation. The biggest difference is that conventional navigation can sail through inertia after the initial acceleration stage, which can save a lot of fuel. But in curvature drive, since the spacecraft
If the motion is zero, then there is naturally no inertia, and it is impossible to rely on inertia for navigation. This means that during the navigation process, the element decay engine must always be on to provide energy for the curvature engine.
This results in the energy consumption of curvature navigation being much higher than that of conventional navigation. Without element decay technology, curvature navigation is simply a mirror in the water and cannot be realized.
This feature has both advantages and disadvantages. The disadvantage is naturally excessive energy consumption, while the advantage is a leap in mobility.
A spacecraft traveling in curvature navigation can accelerate from rest to the speed of light within ten seconds, and can also return from the speed of light to rest within ten seconds.
To put it less accurately, the maneuverability of Xiao Yu's spacecraft has improved tens of thousands of times compared to before.
An hour later, the ship used curvature drive and sailed to the edge of the four-dimensional barrier.
After entering the super-light speed navigation stage, matter will disappear in the entire waveband, and it cannot be seen in visible light, ultraviolet light or infrared light. After Xiao Yu's research, Xiao Yu believes that this is because of the red shift
It is too violent, causing the light to move out of the detectable frequency. However, by detecting the degree of spatial distortion, Xiao Yu can accurately locate it.
Similarly, during super-light travel, all light from the outside is completely invisible because the blue shift is too severe.
In other words, while traveling at super-light speed, this spacecraft is completely isolated from the outside world.
This will bring certain dangers to faster-than-light navigation, because during navigation, the spacecraft cannot detect whether there are obstacles ahead. Short-distance navigation is okay, but long-distance navigation is likely to lead to accidental collisions.
For example, crashing into a star or planet.
In fact, it’s not that a spaceship traveling at super-light speed cannot receive or emit light, it’s just that the red shift or blue shift is too severe, so that such light cannot be detected. In this regard, Xiao Yu has already
Conduct research and try to develop an instrument that can restore the frequency of light, allow you to travel at super-light speed, and detect external intelligence.
However, at this stage, this instrument has not been successfully developed. Xiao Yu needs to continue to conduct uninterrupted research and spend some effort to develop it.
After the spacecraft arrived near the four-dimensional barrier, Xiao Yu focused all his attention here.
Because he does not understand the characteristics of the four-dimensional barrier, Xiao Yu does not know how to break through this barrier. However, in Xiao Yu's speculation, super-light navigation is likely to break through it. Now, it is to test whether Xiao Yu's conjecture
The time is right.
"The collision will occur in five seconds. Five, four, three, two, one..."
Within the field of view of the space distortion detector, the village-class spacecraft suddenly lost its trace.
"Has the breakthrough been successful?" Xiao Yu thought nervously, and immediately commanded the village-level spacecraft to break away from the super-light voyage through long-distance communication, and immediately began to use the instruments on the spacecraft.
, start to detect the external environment.
What you see is nothingness, nothing.
"Where is this?" Xiao Yu thought in confusion, "Could it be that traveling at the speed of light will break into other dimensions? This is too ridiculous."
Xiao Yu controlled the village-level spacecraft to continue its detection. Then, in the space background, the light red barrier caught Xiao Yu's attention.
It was an extremely large red barrier that occupied the entire field of view of the detection instrument.
Xiao Yu's heart gradually sank to the bottom.
The detection instrument of the village-class spacecraft turned around and indeed detected the huge red giant. After the village-class spacecraft sent out a burst of radio waves, satellites scattered throughout the galaxy quickly detected it with the help of this burst of signals.
Settled.
As a result, this super-light spacecraft still did not break through the red barrier. Like the other spacecraft, when it came into contact with the barrier, it was randomly teleported to a place between one billion and one billion one billion kilometers away from the central star.
Point.
Experiments have proven that super-light navigation cannot break through the four-dimensional barrier.
"I should have thought a long time ago that in the face of the four-dimensional barrier, super-light sailing is not possible." Xiao Yu murmured to himself, "If you can break through the four-dimensional barrier just by relying on super-light sailing, then there will be no four-dimensional shield."
What is the value of using it? After all, a fourth-level civilization that has mastered super-light navigation technology may not be able to develop super-light kinetic energy weapons. If it cannot even defend against super-light speed, the value of the four-level protective cover is not as good as the force field protection.
The value of the mask is great.”
"So, how can we break through the four-dimensional barrier?"
Xiao Yu fell into a daze.
Elemental decay and faster-than-light navigation are the biggest technological breakthroughs that Xiao Yu has achieved in the past few hundred years. Moreover, it is foreseeable that Xiao Yu will not be able to achieve the rest in the next hundreds or even thousands of years.
A major technological breakthrough has been made.
"If Taihao is kind to me, then it is impossible for it to create a barrier that cannot be broken through by the technological level of a fourth-level civilization. In other words, on the premise that Taihao is kind to me, it is impossible to break through the fourth-dimensional civilization
The technology of the barrier must be in the technological system of the fourth-level civilization. However, it is not even super-light navigation, so what could it be? After all, super-light navigation is the most significant feature of the fourth-level civilization."
Xiao Yu slowly thought, "Perhaps, it will be an elemental decay bomb? Or a material disintegration ray? Or a large number of super-light kinetic energy weapons bombardment?"
At this moment, Xiao Yu felt that he suddenly lost the direction of struggle.
It is impossible to break through to the fifth level civilization in a short time. Not only that, in the remaining less than 150 years, it is impossible to make another major technological breakthrough. Then Xiao Yu can only rely on
The technology currently available is used to try to break through the four-dimensional barrier.
But... if you can't break through faster-than-light navigation, what kind of technology would that be?
Xiao Yu thought with some confusion, "This can only be tested slowly in the future. I hope I can find a way to break through within one hundred and fifty years."
The radius of the four-dimensional barrier has been shrinking. It is equivalent to a rope around Xiao Yu's neck. When the rope tightens to the point where Xiao Yu can no longer breathe, that is when Xiao Yu will perish.
But Xiao Yu soon discovered that he was wrong again.
Xiao Yu has always ignored a problem before.
By chance, a spacecraft's temperature detector discovered that the temperature in interstellar space was rising.
Before the emergence of the four-dimensional barrier, in this star system, the temperature was 137 degrees at a distance of 2 billion kilometers from the central star. At a distance of 7 billion kilometers from the central star, the temperature was below zero.
One hundred and eighty-five degrees.
The temperature mentioned here is not a purely physical quantity, but a temperature that can actually be measured.
But now, the temperature has changed. Xiao Yu saw that at his location, the temperature had risen from 137 degrees to 145 degrees without knowing it.
Seven billion kilometers away from the yāng star, the temperature has risen to minus 150 degrees.
This means that within the four-dimensional barrier, the temperature of the entire stellar system is constantly rising.
Xiao Yu soon found out the reason.
"So that's it... Because of the existence of the four-dimensional barrier, the heat of this star cannot be radiated out, but can only accumulate in the galaxy. This will naturally lead to a continuous rise in temperature."
After coming to this conclusion, Xiao Yu began to care about another question. That is, how fast will the temperature rise? When will it rise to a level that he cannot bear?
For this question, Xiao Yu quickly found the answer through calculation.
The conclusion is that the temperature will rise faster and faster. In fifteen years, no matter how far away from the star it is, the lowest temperature in the galaxy will reach more than 3,000 degrees. And Xiao Yu’s spacecraft will
In such a temperature, more energy will have to be consumed to resist the high temperature.
The star system within the four-dimensional barrier will become a veritable steamer. Xiao Yu's spaceship is the steamed buns being continuously cooked in the steamer.
"In fifteen years, facing the rising temperature, I will consume all the reserve energy and have to dismantle the remaining spacecraft to use as fuel for the elemental decay engine."
"But even so, I can't sustain it for too long. The increase in temperature will only increase the energy consumption. If calculated this way... after the temperature reaches more than 3,000 degrees, I still have five years.
"
"If I have been unable to break through the four-dimensional barrier, at the last moment, after dismantling all the remaining spacecraft, I will have to obtain energy by disassembling the equipment inside the Hebei..."
"If calculated comprehensively, my time is not one hundred and fifty years, not one hundred years, but only twenty years... In twenty years, I must find a way to break through the four-dimensional barrier, otherwise I will die...
