In a galaxy in the core area of the Milky Way, the three space battleships Yangzhou, Qingzhou, and Jizhou are parked quietly in the void. Scientists are extremely busy, constantly exploring the surrounding void of the universe.
This is the first time that scientists have observed a black hole at such a close distance. Although it is still more than 2,000 light-years away from the black hole, this is the first time in human history that a black hole has been observed at such a close distance.
Of course, observation is not actually scientific.
The mass of a black hole is so huge that even light cannot escape its powerful restraint, so it cannot be seen at all. Black holes can only be detected by scientific means.
"Gee, observing a black hole at such a close distance feels completely different."
"It turns out that black holes are constantly devouring cosmic matter in the surrounding void, and they are also constantly ejecting high-energy matter into the void of the universe."
Zhou Yu couldn't help but be overjoyed when he looked at the images monitored by various monitoring instruments.
It has always been generally believed that black holes can only go in and out, that is, they are always swallowing matter in the surrounding void, but they never spit out matter.
It was not until later, with the continuous research of cosmic astronomical scientists, that they discovered that black holes are actually constantly spitting out matter, which does not mean that they can only go in and out.
Sometimes it even spits out a large amount of cosmic matter and energy on a large scale. This phenomenon has also been detected by astronomical scientists.
Now that they are close enough to the black hole, scientists are surprised to find that the black hole is constantly devouring the surrounding cosmic matter and energy, but at the same time it is constantly ejecting energy and matter.
But in normal times, this phenomenon is relatively weak and cannot be detected if it is far away. Only when it is close enough can scientists detect this phenomenon.
"Then what does this mean?"
"If we talk about the power of the black hole itself, this black hole should not be able to go in or out, because of its large mass and strong gravity, and even light cannot escape."
"But the speed of the ejected energy and matter is far less than the speed of light. This is very contradictory."
Soon, Zhou Yu frowned and started thinking again.
It stands to reason that a black hole has a very large mass and a strong gravitational force, and even light will be sucked away by it. It should only be able to go in and out, but this is not the case with a black hole. It is also losing its own mass all the time, even according to the
Scientists calculate that massive black holes like the black hole at the center of the Milky Way.
It only takes tens of billions of years for its mass to drain away.
This is a very contradictory thing.
But in itself, if a black hole can only enter but not exit, this also violates traditional cosmological theory and physical theory.
Among them, the law of entropy increase has been seriously violated, because according to the law of entropy increase, the universe is constantly tending to infinity, and all energy activities in the universe will eventually return to calm, and the final outcome of the entire universe is to become dead and silent.
A world without any energy activity.
Scientists have confirmed this by observing changes in the distance between galaxies. According to what is currently observed, almost all stars are constantly moving away, exhibiting red shifts. Scientists have also inferred that the universe is constantly moving
Expand, expand.
Furthermore, it is inferred that the birth of the universe may have been caused by the Big Bang at the singularity, which can also well explain why the stars currently observed are all redshifted.
At this moment, Zhou Yu frowned and kept thinking.
As humans have more and more activities in the interstellar universe, the scope and area of exploration are getting wider and wider, and the understanding of the interstellar universe is gradually deepening.
We are constantly learning about the world, and are gradually learning more and more mysteries of the universe, but at the same time, we are also gradually discovering more things that are currently difficult to understand and explain.
It is said that the more you know, the smaller you feel, because you can always see more problems.
"The only thing that can explain this phenomenon, I think, may be space!"
At this time, Zheng Yuan thought for a while and said: "When we squeeze something hard, there will be a rebound force on the thing."
"The black hole itself has a very large mass and has a huge influence on the surrounding universe, which will inevitably cause squeezing, distortion, etc."
"The black hole will also generate a force in the same space, and this force will eject part of the matter and energy from the black hole."
"What you said makes sense."
After Zhou Yu listened, he thought about it and nodded solemnly in agreement.
"Speaking of which, as a biology researcher, how did you start studying cosmology and space science?"
"I have no choice. There is no living planet here. I can't waste my time and youth studying a hammer, so I temporarily changed my field to study cosmic astronomy and space science."
"I find cosmic astronomy and space science to be very interesting, no less interesting than our biological sciences."
Zheng Yuan smiled and said.
"..."
"You are really a pig sticking a green onion through your nose. How vast is cosmology and space science, how can it be compared to those of you who are engaged in biological research."
Zhou Yu curled his lips and said, looking out the window. The density of stars here is very high, and the universe is much brighter than other places.
At this moment, the battleship suddenly jolted, and in the void outside, a wave was set off in the space like an ocean wave. The speed was very fast, and it disappeared completely in the blink of an eye.
But Zhou Yu saw it clearly, and at the same time, everyone on the battleship clearly felt the bumps and fluctuations just now. This feeling was like riding a car on a bumpy road on the planet.
Zhou Yu widened his eyes slightly, and looked at the people around him in disbelief. At this moment, everyone was like Zhou Yu, all of them had their eyes widened, and they even doubted whether they had just...
Misconception.
"The spaceship seemed to have a jolt just now!"
"Am I feeling wrong?"
"This spaceship is well in the void of the universe, how can it cause turbulence?"
"I seemed to have felt it just now."
Everyone looked at each other, big eyes and small eyes.
"You just felt it. I could see it clearly just now. The void of the universe outside was swinging by like a wave."
Zhou Yu looked at the void of the universe outside again. At this moment, it was as calm as water, as if it had not changed forever. Where could he still see the fluctuations in space just now.
"Such clear spatial fluctuations are exactly what I inferred."
"The black hole at the center of the Milky Way is so massive that it puts tremendous pressure on the surrounding space and causes many changes in space."
"Haha, from now on, when studying space technology, you can go to the center of the Milky Way, where you can observe the fluctuations of space."
Zhou Yu laughed happily.
He has been studying space technology for a long time, but space is something that cannot be seen or touched, and there is no way to measure it. It is not the same thing as space in the traditional sense.
Zhou Yu studies space technology.
According to the inference of scientists, the universe ultimately has no time, space, and many other things. However, after the Big Bang, the universe has space, time, everything, and so on.
Therefore, space and time should be the most basic elements that make up the universe. If we can thoroughly study these two things, we should be able to completely understand the entire universe and grasp all the mysteries of the entire universe.
But scientists have always had no clue about this, and it is even difficult to make theoretical illusions and speculations. Space technology is too esoteric and obscure. The key is that there is nothing that can be seen intuitively.
What is observed cannot be studied.
This is somewhat similar to the research on the microscopic particle world. The reason why the research on the microscopic world is progressing slowly is that most research is only in the theoretical research stage.
The very important reason is that the microscopic world is also too small, and scientists simply cannot observe the microscopic world and conduct research.
Even if there are particle collisions and the like, research progress has been very slow, and it is always difficult to make any breakthroughs.
The essence is similar. The study of space technology can be said to be the understanding and study of the universe in the macroscopic world. When you are in it, you simply cannot feel the changes in the vast universe, and there is no way to study it.
"Space fluctuation!"
Zhou Yu sat directly on the floor and kept looking at the vast starry sky outside, constantly recalling the fluctuation he just saw in his mind.
It played in his mind over and over again, and he thought about it carefully, trying to explore the mystery of space technology.
The people around looked at Zhou Yu's appearance, and immediately signaled to each other to be quiet, and then left quietly. Zheng Yuan even asked people to seal off the surrounding area, so that no one could disturb Zhou Yu, and allowed him to slowly move on by himself.
to think.
Sometimes the progress and development of science rely on the epiphany of genius, and this kind of epiphany is hard to come by, and if you miss it, you may never be able to catch it again.
