Acoustic black holes are concepts derived from condensed matter physics.

A so-called black hole is an area where even particles moving at the speed of light, such as photons, cannot escape.

Then, the area where phonons cannot escape can be called an acoustic black hole.

Let an object move back and forth at supersonic speed in the medium, and finally form a turbulent flow that can swallow all the sound.

It has singularity, and has a difficult to figure out nature,

This is also called "acoustic black hole".

The method of emitting Hawking radiation from an acoustic black hole is "phonon".

This coincides with the method of relief to the Demon King.

Using this technique, scholars simulate black holes and explore some of the possible properties of real black holes.

This is also a rare moment of glory for Liu Yunzong in the last 500 years.

This is even the first time that Liuyun Zong affiliated Zongmen has received a large number of equipment orders in so many years.

But if an acoustic black hole can release phonons in this world, it means that Hawking radiation is also likely to be established in this universe. Black holes are not only inaccessible, there is still a lot of information that will appear in the universe with Hawking radiation.

In this case, the probability of a black hole killing a predecessor is undoubtedly much smaller.

Perhaps only Kerr Black Hole with the dual event horizon can effectively kill the former.

Of course, the benefits of acoustic black holes are not the only ones.

It is of great help in the research of black holes.

Of course, the human race still hopes to be in direct contact with the black hole.

"As a matter of fact, since the Iron Kings are black hole jet civilizations, their living area will not be more than 100,000 light-years away from the black hole ... and the name of" The Lord of the Eight Thousand Returning to the River "also shows them There are about 8,000 black holes under control. Maybe at that time, we can also get the opportunity to study black holes. "Wang Qi thought so.

Of course, this is all speculation and can only be regarded as a good vision.

The relationship between the Iron King and the Dragon is not necessarily very good.

The iron clan may not be willing to help the dragon clan.

After learning the news, Wang Qi once again returned to his potential training ground, waiting for the Dragon Emperor to wake up and wait for the opportunity.

The three months mentioned by the demon emperor are actually "the shortest time".

They actually waited for seven months.

In these seven months, the human race has once again changed.

Due to the establishment of time-reversal symmetry, the concept of "reverse universe" or "reverse temporal universe" was also proposed.

Some people think that this statement is just like the "dark matter" model, just to explain some new problems that cannot be explained now.

At least in China, mainstream research has not yet accepted the existence of dark matter. There is not enough data to show that there exists a substance that does not interact with ordinary matter, has only gravity, and can only distort space-time.

In the view of some people, "reverse time series universe" also has this trend.

But the limited foresight that the future belongs to in the past supports the inversion of time symmetry.

Under this model, there is indeed a reverse time series universe. The time arrow of that universe is the opposite of the physical universe that we usually touch.

And this reverse time series universe, combined with the positive time series universe, is the whole picture of the entire universe.

Of course, the opposition of this model is also very loud.

Opponents soon came up with the expression "fast material universe", or "superluminal universe".

This universe, in addition to the low-light-speed universe we are in contact with every day, there is also a high-light-speed universe-of course, it can also be called "superluminal material flow".

According to the principle of symmetry, the faster the speed of matter in the superluminal matter universe, the lower the energy, the slower the speed, and the higher the energy.

Tachyons absorb energy when they slow down, and release energy when they accelerate.

The "speed of light" is the axis of symmetry of these two universes.

According to the principle of phase-conformity, superluminal matter will not interact with low-speed matter. However, the realm of the past and the future is that the body has completed the mixing with the superluminal matter.

At least the "fast son communication" theoretically has a speed of light that violates the law of cause and effect.

This metaphor was like irony at first, like the cat that waved Tianjun.

But quickly, this irony was actually accepted by people.

There are actually supporters who try to prove the equivalence of "reverse time-series universe" and "superluminal material flow".

The closed-time curve model is not compatible with this statement.

This is another round of debate.

While in the debate among the monks of the Alliance, the palace was not idle.

They are marching deeper.

Since the probability of time inversion symmetry is established on the universe scale is very large, the new particle model has to take this into account. Moreover, the super-symmetry that should exist in the micro-domain of the Auraless universe is gone.

The beautiful and neat array of the "standard model" is also fragmented.

However, with the joint efforts of many Xiaoyao monks in the Nine Palaces, a "standard model" of the aura universe is gradually taking shape.

In this process, there were two free monks who successfully testified.

They intend to use a time of about a hundred years to verify this.

This involves a series of empirical evidence, which requires the entire palace, even the help of many martial arts such as Guiyimeng, Xuanxingguan.

And if this plan is completed, then it will be the most important achievement in the next two hundred years.

That's how time passes.

Until half a year later, the Xihai earthquake.

No, it is not appropriate to say that the earthquake was down. In the void, there are infinite spiritual forces dangerous, shaking the earth and the sea.

The waves are running. A huge wave of several meters high rushed to the west, but was quickly calmed down by the Xianmeng monks prepared in advance.

This lasted only a short moment.

Dragon Emperor appeared silently on the back of the moon. He is now fully awake. The strongest person in the observable universe is no longer asleep. He can completely restrain his strength and ensure that he will not have much impact on the outside world.

At this moment, the only aftermath, the number of sunspots on the side of the sun, suddenly increased by a few percentage points.

The Dragon Emperor is 2,000 kilometers long, which is not huge compared to other powerful dragons. Although he can also take out the flesh that he stored in the closed space, it becomes even bigger. But for him, this is the most suitable size for exerting power. Dragon Emperor disappeared for a moment.

The next moment, he appeared on the sea dragon-the forbidden god.

Long Huang whispered: "My brother, you are not willing to survive for the future I have chosen. So, are you still willing to fight for your past friends?"

no answer.

Because Dragon Emperor soon knew the future.

Shi Long Xuanyu took the initiative to tell him in a "probably existing future".

Then, countless fissures appeared on the surface of Hailong-Forbidden God.

The main components of the sea dragon-forbidden **** include nitrogen, water, ammonia, methane and other materials, and the bottom layer is cracked. Substances with lower boiling points vaporize almost instantaneously. The violent blast ripped open the planet's thin atmosphere. Even the small branches create mushroom clouds on the ground.

The moment the Dragon Emperor withdrew his power to suppress Shi Long Xuanyu, Shi Long Xuanyu had already reacted.

Of course, he did not come out instantly.

Because there is not only one dragon clan sealed within the Sea Dragon-Forbidden God.

The rift that runs through the entire celestial body expands bigger and bigger. Dragon claws protruding from the mountain. The golden energy surged.

The Dragon Emperor quietly filled in a large number of small meteorites prepared in advance to ensure that after Shi Long Xuanyu left, the quality of the Hailong-Forbidden God fluctuated so as not to let this big Japanese territory fall into turmoil.

A large amount of rock was swept into space because of this suddenly vaporized material, and then was stirred by the dragon emperor's tail to fill the surface of the celestial body.

Although both sides are disagreeable enemies, there is an unusual tacit understanding in this matter

It was not until one quarter of an hour that Shi Long Xuanyu stretched his body from the planet like a shelled dragon.

In terms of body size alone, he is a bigger model than Dragon Emperor.

The dragon stared at the Dragon Emperor and said, "Yueluo, no matter how many years you meet again, you are all the same."

"I just believe that in the choices I have made now, there is a better future I haven't seen before." Long Huang said: "Limited foresight, after all, is only limited. To pursue infinity with limited ... too big, I dare not Gamble with the lifeblood of the Dragon Clan. "

"Let the so-called dependents help you to walk? You really can think of Yueluo." Shi Long Xuanyu's tail pointed to the distant capital-Demon Prison: "Isn't that the evil barrier to you?"

"If the" that evil barrier "is a dragon clan, and it is you who is being hurt now, and it is the dragon clan that is suffering the overthrow?"

The Dragon Emperor asked calmly.

"I can give you my native land to play tricks and let you develop your dependents." Shi Long Xuanyu roared: "But I really didn't expect that you would actively suppress the appearance of the limit of doctrine? You even have to let all The limit of your joint is sleeping! Including yourself! "

"The power of foresight and wisdom are not the same thing. Maybe there are things that the power of foresight can't let us see, but the wisdom can. We have traveled all the places where power can reach, but we have never reached the 'other shore' of wisdom. These All my friends told me now. "Long Huang still said this way:" Do you know how many times the Hou Chi split? "

"We are different from Hou Chi! Is blood our natural connection?"

"Remember the Yuan tribe?"

The two dragons confronted each other indifferently, but no one could persuade anyone.

Finally, Shi Long Xuanyu asked: "Do you say the same to Xing Sheng?"

"Yes." Longhuang Hanshou: "I am enough. As long as I am here, the former will not lightly start the war. In addition, my brother ..."

"Dare not have a brother like your majesty." Shi Long Xuanyu sneered.

"Shi Long's." Long Huang said: "I have no intention of arguing with you about this kind of thing. We can re-discuss the issue of obedience. Now we are facing another problem."
