Chapter 472: Discussion of Super Black Holes

"I want to hear about it. Pen × fun × Pavilion www. biquge。 info”

Yuan Haochen didn't care whether the dark energy civilization scientist's humble remarks just now were modest, and it would not hurt to listen to it.

"Black holes grow by devouring the material around them, which is a simple truth and an easy to observe fact. But ever since the discovery of those ancient superholes, our scientific field has been trying to understand what led to the process that led to a small black hole that could grow and expand so quickly after the Big Bang. "Dark Energy Civilization scientists began to describe it.

"If we can understand and even grasp the mysteries, then it is possible for us to quickly feed the black holes in the Milky Way galaxy one bite at a time. In fact, several processes limit the rapid growth of black holes, for example, gases usually do not fall directly into the black hole, because they are often restrained and flow in a spiral, and finally enter the black hole bit by bit, in strands. And, when the gas is finally swallowed by the black hole, the light it emits cancels out with gravity, a process that likewise slows down the flow of food from the black hole. ”

Speaking of which, the scientists of the dark energy civilization said that this is really a very regrettable thing, otherwise they could use technology to cultivate and obtain more medium or large black holes.

But in fact, the more gas a black hole swallows, the stronger the light and radiation it emits. Eventually, this black hole will starve for its own dazzling light. Because the light radiating outward will become stronger and stronger, so strong that it will disperse all the gas that falls on the black hole, and may even cut off its "food" supply.

"Is there any special difference between the growth of those ancient superholes and the black holes in the Milky Way?"

Yuan Haochen asked, while looking at the edge of the Dutar black hole, those interstellar materials are gathering around the black hole into a disk, frictional heat generation produces extremely high temperatures, emitting dazzling light, generating a magnetic field to drive the matter to gallop outward in the jet stream, which is a sign that the Dutar black hole is greedy for food.

"It's not clear, and neither are we!" "We have designed a model in which small black holes continue to sweep more and more gas into their orbits through rapid twists and turns. After entering orbit, the gas then began a slow spiral motion. Models have shown that the more massive a black hole is, the faster it will swallow up the air current. Moreover, this growth rate will increase exponentially in the future. ”

"In addition, we suspect that in the early days of the universe, the gas flow was very cold and dense. Far from being comparable to the thin gas streams we see in the universe today! ”

Yuan Haochen continued to listen to the other party's description silently and thoughtfully.

"We thought it would be possible to explain it this way: supermassive black holes start as very small seed black holes and grow slowly by swallowing the surrounding gas and other interstellar material. But later observations and studies have shown that these are by no means the whole story of the black hole's growth. For these ancient giant black holes, we must find a more comprehensive theoretical explanation. ”

"How did these monster-level black holes grow so fast?" The dark energy civilization scientist glanced at Yuan Haochen and the other human scientists, and then asked himself, "Theoretically, it would take at least 30 million years for a black hole to double its mass. To leap from 100 times the size of an ordinary star to billions of times, the mass of a black hole needs to double at least 23 times. ”

"That is, it will take at least 700 million years for a seed black hole to grow into a superblack hole. Moreover, we must tailor an endless supply of gas for this seed black hole to feed her. ”

Yuan quickly calculated this time formula.

"Perhaps. In fact, the periphery of each black hole in the universe is basically chaotic and changeable. Therefore, it is not easy, or rather difficult, to swallow gas so quickly and for so long. "Scientists of the dark energy civilization believe that it is unscientific to assume that a black hole can accretion gas all the time.

"On the one hand, we can't deny the exception, and perhaps at the edge of the universe, there is such a rare environment that allows those superblack holes to be devoured for billions of years." Yuan went on to speculate, "On the other hand, as the number of super-black holes discovered increases, exceptions will not be enough to justify, so there must be some kind of law that we don't know yet." ”

"Maybe, that's why I said, we don't have a standard answer either." The dark energy civilization scientist continues, "If we talk about the law, then there is another possibility: we need a seed black hole with a greater mass. ”

"However, almost all of the more massive seed black holes are concentrated in outer space in the universe." Hara knows that the more massive seed black holes (medium-sized black holes) generally come from the supernova explosions of the first generation of massive stars, and these first-generation stars have long since moved away from the edge of the universe as the universe continues to expand.

"On top of that, we can assume something bigger. For example, super-black holes originated as a result of the collapse of the core of a galaxy, but there are still many unsolved ...... to this hypothesis."

......

Hundreds of thousands of scientists from the expeditionary force's scientific team are conducting large-scale experiments around the black hole and collecting and analyzing scientific data. It took nearly 10 years to complete 60% of the research task.

Meanwhile, in another corner of the galaxy, the human fleet carrying out the Hider program is expected to return to its original location through a space tunnel.

"Commander! Oh no! ”

This time, the capable warrior ran all the way to report to Yu Liang.

"Panic what!"

Yu Liang rebuked, he always believed that a qualified warrior should take any situation calmly, especially the scouts under him.

"I'm sorry, Commander." The capable warrior immediately raised his head and chest, raised his neck and reported to Yu Liang, "In the predetermined position ahead, there is no space tunnel of dark energy civilization!" There is also no related equipment. ”

"Are the coordinates accurate!?" Yu Liang frowned and asked.

When the other operational staff officers in the command room heard this, they also quickly gathered.

"Exactly!!" Without hesitation, the capable fighter replied, "The monitoring detachment has repeatedly confirmed." ”
