Chapter 187: temperature

The village-level spacecraft is still accelerating, and it has stopped at the speed of three times the speed of light.
Three times the speed of light is the highest speed Xiao Yu can currently reach.
Fifty years later, the radius of the four-dimensional barrier has been reduced from 10 billion kilometers to 7.5 billion kilometers. This means that from the center of the galaxy, at the speed of this village-level spaceship, it only takes two and a half hours to sail this long distance.
The curvature-driven method is not the same as conventional navigation. The biggest difference is that after the initial acceleration phase, conventional navigation can sail by inertia, which can save a lot of fuel. However, in the curvature drive, since the spacecraft's motion is zero, there is no inertia naturally, and it cannot sail on inertia. This means that during the sailing process, the element decay engine must always be running to provide energy for the curvature engine.
This causes the energy consumption of curvature navigation to be much higher than that of conventional navigation. Without elemental decay technology, curvature navigation is simply the moon in the water and cannot be achieved.
This feature has both advantages and disadvantages. The disadvantage is naturally too much energy consumption, and the advantage is a leap in mobility.
A spacecraft traveling by curvature can either accelerate from rest to the speed of light within ten seconds, or return to the rest from the speed of light within ten seconds.
To put it in a less precise way, the mobility of the Xiao Yu spacecraft has been increased by tens of thousands of times compared with the past.
An hour later, the ship used a curvature-driven approach to the edge of the four-dimensional barrier.
After entering the stage of super-light speed navigation, the substance will disappear in the full band, and it will not be visible whether it is visible light, ultraviolet light or infrared light. After Xiao Yu's research, Xiao Yu believes that this is because the red shift is too intense, which causes the light to move out of the detectable frequency. But by detecting the degree of spatial distortion, Xiao Yu can accurately locate it.
Similarly, in super-light speed navigation, because the blue shift is too drastic, all external light is completely invisible.
In other words, this spacecraft is completely isolated from the outside world during super-light speed navigation.
This will bring certain danger to super-light speed navigation, because during navigation, the spacecraft cannot detect whether there will be obstacles in front of it. For short-distance navigation, it is okay to say that long-distance navigation may cause accidents. For example, something that crashed into a star or planet.
In fact, the spacecraft traveling at super-light speed is not unable to receive or emit light, but it is because the red shift or blue shift is too severe, which makes it impossible to detect such light. In response to this, Xiao Yu has been conducting research to try to develop an instrument that can restore the frequency of light, allow himself to navigate at speeds of light, and detect external intelligence.
However, at the present stage, such an instrument has not been successfully developed. It is still necessary for Xiao Yu to continue his uninterrupted research and spend some effort to develop it.
After the spacecraft arrived near the four-dimensional barrier, all of Xiao Yu's attention was placed here.
Because he did not understand the characteristics of the four-dimensional barrier, Xiao Yu did not know how to break through this barrier. But in Xiao Yu's speculation, super-light speed navigation is likely to break it. Now is the time to test whether Xiao Yu's conjecture is correct.
"The collision will happen in five seconds. Five, four, three, two, one ..."
In the view of the space distortion detector, the village-level spaceship disappeared abruptly.
"Did the breakthrough succeed?" Xiao Yu thought a little nervously, and immediately commanded the village-level spacecraft to escape from the speed of light through super-long-range communication, and immediately began using the instruments carried on the spacecraft. Began to detect the external environment.
Into the eye, there is nothing, nothing.
"Where is this?" Xiao Yu thought for a moment, "Is sailing at the speed of light faster and breaking into other spaces? It's too much."
Xiao Yu steered the village-level spacecraft to continue the exploration, and then, in the space background, the pale red barrier caught Xiao Yu's attention.
It was an extremely large red barrier covering the entire field of view of the detection instrument.
Xiao Yu's heart gradually sank to the bottom.
The detection device of the village-level spacecraft turned the direction, and it really detected the huge red giant. After the village-level spacecraft sent out a burst of radio waves, the satellites scattered throughout the galaxy, using this burst of signals, quickly positioned it.
As a result, the superlightship still hasn't broken that red barrier. Like the rest of the spacecraft, when it came into contact with the barrier, it was randomly transmitted to a point between 1 billion and 1.1 billion kilometers away from the central star.
Experiments have proved that sailing beyond the speed of light cannot break through the four-dimensional barrier.
"I should have thought that sailing at the speed of light would not be possible in the face of the four-dimensional barrier." Xiao Yu muttered to himself, "If the four-dimensional barrier can be broken only by sailing at the speed of light, then the four-maintenance cover will not be available. What is the value of use. After all, the fourth-level civilization that has mastered the technology of super-light speed navigation may not be able to develop kinetic light weapons that are faster than the speed of light. If the speed of light cannot be defended, the value of the four maintenance cover is not as good as force field protection The value of the hood is great. "
"So, how can we break through the four-dimensional barrier?"
Xiao Yu was in a daze.
Element decay and super-light speed navigation are the greatest technological breakthroughs Xiao Yu has made in the past few hundred years. Moreover, it is foreseeable that in the next few hundred years or even thousands of years, Xiao Yu will not be able to achieve the remaining major technological breakthroughs.
"If Taihao is kind to me, then it will not be able to create a barrier that cannot be broken with the scientific and technological level of the fourth-level civilization. In other words, under the premise that Taihao is kind to me, it will break through the four-dimensional The science and technology of the barrier must be in the scientific and technological system of the fourth-level civilization. However, it would not even be faster than the speed of light. What would it be? After all, the speed of light is the most prominent feature of the fourth-level civilization. "
Xiao Yu was slowly thinking, "Maybe an elemental decay bomb? Or material disintegrating rays? Or a large number of super-light kinetic energy bombers?"
At this moment, Xiao Yu felt suddenly lost his direction of struggle.
It is impossible to break through to the fifth-level civilization in a short time. Not only that, but in less than 150 years, it is impossible to achieve a major technological breakthrough again. Then Xiao Yu had to rely on the technology he currently has to try to break through the four-dimensional barrier.
But ... Can't break through at the speed of light. What technology would it be?
Xiao Yu was thinking with some confusion, "This can only be slowly tested in the future. Hope, I can find a breakthrough in 150 years."
The radius of the four-dimensional barrier has been shrinking. This is equivalent to a rope around Xiao Yu's neck. When will this rope shrink to the point where Xiao Yu can't breathe, it is when Xiao Yu perishes.
But Xiao Yu soon realized that he was wrong again.
Xiao Yu had previously ignored a problem.
By chance, the temperature probe of a spacecraft found that the temperature of interstellar space was rising.
Before the emergence of the four-dimensional barrier, the temperature of the star system in this galaxy was two billion kilometers away from the central star, at 137 degrees. At a temperature of seven billion kilometers from the central star, the temperature is 185 degrees below zero.
The temperature mentioned here is not a simple physical quantity, but a temperature that can be measured.
But now, this temperature has changed. Xiao Yu saw that at his location, the temperature had risen from 137 degrees, and unknowingly had risen to 145 degrees.The temperature had been 7 billion kilometers from the central star, It rose to 150 degrees below zero.
This means that within the four-dimensional barrier, the temperature of the entire galaxy is constantly rising.
Xiao Yu quickly found the reason.
"It turned out to be this ... Because of the existence of a four-dimensional barrier, the heat of this star cannot be radiated, but can only be accumulated in the galaxy. In this way, it will naturally lead to a continuous rise in temperature ~ EbookFREE.me ~ After reaching this conclusion, Xiao Yu began to care about another question. That is, how fast does the temperature rise? When will it rise to an unbearable level?
Xiao Yu quickly found the answer to this question through calculation.
The conclusion is that the temperature will rise faster and faster. After fifteen years, no matter how far away from the star, the lowest temperature in the galaxy will reach more than 3,000 degrees. And Xiao Yu's spacecraft, in such a temperature, will have to consume more energy to resist high temperatures.
The galaxy within the four-dimensional barrier will become a veritable steamer. Xiao Yu's spacecraft is a steamed bun in a steamer.
"Fifteen years later, in the face of rising temperatures, I will use up all of my reserve energy and have to dismantle the remaining spacecraft as fuel for the element decay engine."
"But even so, I can't support it for too long. An increase in temperature will only make energy consumption more and more. In this calculation ... After the temperature reaches more than three thousand degrees, I 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 dismantling the equipment inside the Hebei ..."
"In terms of comprehensive calculations, 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 ... ... "
