Chapter 704 Gravitational Wave Signal
On the other side of the Pacific Ocean, inside the Pentagon, at the Naval Command!
The Naval Command is one of the three branches of the Department of Defense of the United States, also known as the 'Washington Naval Compound', which consists of three units: the Navy Office, the Department of Naval Operations, and the Marine Corps Headquarters.

At this time, an old man in the Navy Command was holding a naval meeting. More than 100 people participated in the meeting, each of whom was a powerful figure in the navy.

A man in his 50s turned on the screen and saw a submarine appearing on the screen. The submarine was not big. The man said in a deep voice: "According to various data and analysis by professional technicians, the location where the Los Angeles nuclear submarine disappeared is probably at At this point, we have not received any news about the submarine so far, and we have every reason to believe that the submarine has unfortunately died."

"As for whether the nuclear submarine hit a submarine mountain, a sunken ship, or a whale, there is no evidence so far, and I can't say anything. You can use your imagination freely. After all, any possibility is possible." The man shrugged and said in a humorous tone.

"Shit, they are too courageous. Don't they know that there are nuclear reactors and nuclear weapons on the submarine? If there is an explosion, can they bear the responsibility?" An old man said angrily: "What do they want to do!"

"Boris, don't forget, it was our nuclear submarine that crossed Guam and violated the documents signed by both parties. We don't take it seriously! At the same time, unfortunately, we have no evidence that they sank the Los Angeles-class nuclear submarine. We said Our doubts, people instead asked us why we violated the signed document, how should we explain it?" An old man said very rudely.

"Trent, what do you mean, now we have lost a Los Angeles nuclear submarine. This is a huge loss. We don't have many submarines in service. If we lose one, we will lose one. Those old men will not Give us the funds to build nuclear submarines.” Boris said dissatisfiedly, in the past 16 years, with the service of the nuclear-powered aircraft carrier USS Carter, the total tonnage of the US Navy has not increased but decreased, because some ships have reached the service life and have to Decommissioned, but there is not enough funds to build enough ships to supplement.

Up to now, although the Navy has two ocean fleets, the Atlantic Fleet and the Pacific Fleet, there are also seven major fleets, 12 aircraft carrier battle groups, and 12 carrier-based aircraft wings, mainly equipped with 60 submarines and 133 large Mizuki ships. Combat ships, 2900 aircraft, and 1500 helicopters may seem powerful, but they no longer have sufficient dominance.

Even because of financial reasons, the aircraft carrier fleet can't cruise the ocean recklessly as before. After all, such large surface combat ships are all money.

"The new news is very bad. Our funding may be cut by another 10%!" Said the old man Lewis who was sitting at the front in a deep voice.

Everyone in the conference room has experienced the era when the American navy was powerful and invincible. At that time, the size of the navy exceeded the sum of the next ten, and it could fight two large-scale wars at the same time and win them.

But up to now, this situation has long been broken. This is very infuriating, but there is no way. They have suffered a lot from several confrontations. They had to agree to conduct peaceful negotiations, and then reached an agreement and signed an agreement.

"What? Are they crazy! Do we want all our ships to lie in the military port?" Triet's expression changed. The annual maintenance and operation costs of such a large fleet are very high, let alone There is a soldier's salary.

The current military expenditure is no longer enough to replace the warship, and if it is cut by 10%, it is unimaginable for Triet, it will be a disaster.

In the conference room, there were constant scoldings. Their interests are the same in terms of military expenditure. Everyone can be better off if they have funds. If they don’t have enough funds, everyone’s life will be tight. Now they are reducing military expenditure by 10%. A very large number, they are difficult to accept.

In the United States, the most important thing is the navy. The navy's military expenditure is the largest, which means that the military expenditure will be reduced by 10%, and the navy will lose the most.

"A few days ago, Chester told me that those people are going too far now, and it's time to express our voices. What do you think about this?" Lewis' eyes became sharp.

And his words were like a bomb going off in the meeting. They are not stupid people who can reach this position. On the contrary, they are all very smart. They know exactly what Lewis means by expressing our voice.

After a low-pitched discussion, everyone showed firm eyes, stood up and saluted Lewis.

Huaxia, Beijing, and Qin Yuanqing are participating in a special meeting, which is basically attended by theoretical physicists and astronomers.

"Academician Qin, all experts and representatives, after our careful time, the signal observed by the Purple Mountain Observation Center came from 28.7 billion light-years away, when two super-massive stars with 30 times the mass of the sun and 40 times the mass of the sun collided. The gravitational wave signal generated by the merger!" said the director of the Purple Mountain Observation Center solemnly.

"I knew it! I knew it!" Dean Yang from the Physics Department of Shuimu University burst into tears. The observation of gravitational waves is a profound research, and they have put in a lot of effort for it.

"I couldn't believe that I would be so lucky. I didn't expect to see gravitational waves confirmed in my lifetime!" Academician Guo of Yanda University was equally excited.

The research on gravitational waves has been going on for more than a century, 120 years to be exact!

In 1916, the year after Einstein proposed the gravitational field equation, he made his famous prediction of gravitational waves: changes in the gravitational field propagate at the speed of light in the form of waves, and gravitational waves are ripples in the curvature of space-time.He also predicted that gravitational waves would stretch space-time (objects) in a certain cross-sectional direction while squeezing space-time (objects) in a perpendicular direction.

Today, Einstein's paper on gravitational waves is still preserved in the Einstein Archives in Jerusalem!In the next hundred years, there was a fierce debate in the physics community about the existence of gravitational waves; scientists have done calculations and found that the amount of compression and stretching of gravitational waves is extremely small, which is "fractional order of atomic diameter".In other words, it's hard to spot.

But in the face of such a challenge, physicists did not give up. American physicists Joseph Hooton Taylor and Russell Allen Hulse jointly observed the pulsar binary star system PSRB1913+16 and discovered the gravitational force for the first time Indirect quantitative evidence for the existence of waves, for which they both won the Nobel Prize in Physics in 1993.

The California Institute of Technology and the Massachusetts Institute of Technology jointly launched the Laser Interferometer Gravitational-Wave Observatory project-the famous LIGO. They used the US$3.94 million funded by the National Science Foundation of the United States in Livingston and Washington, Louisiana. In Hanford, California, two vacuum tube launchers with a length of 4 kilometers were built for the detection of gravitational waves.

2016年2月11日，LIGO科学合作组织和Virgo合作团队宣布他们已经利用高级LIGO探测器，已经首次探测到了来自于双黑洞合并的引力波信号。2016年6月16日凌晨，LIGO合作组宣布：2015年12月26日03:38:53，位于美利坚美国汉福德区和路易斯安那州的利文斯顿的两台引力波探测器同时探测到了一个引力波信号;这是继 LIGO 2015年9月14日探测到首个引力波信号之后，人类探测到的第二个引力波信号。

On October 2017, 10, scientists from many countries across the country held a press conference simultaneously, announcing that for the first time, humans directly detected gravitational waves from the merger of double neutron stars, and at the same time "saw" the electromagnetic signal emitted by this spectacular cosmic event.

However, after Qin Yuanqing perfected the string theory and proposed the conch physical model, theoretical physicists later found that the gravitational waves observed before were actually controversial, not direct evidence, at most. It is regarded as the distance evidence of gravitational waves.After all, even black holes do not exist, so the original rhetoric is naturally not credible.

After that, physicists and astronomers continued to observe the universe, hoping to obtain direct evidence of gravitational waves and prove the existence of gravitational waves.

And this exploration, in the past more than ten years, finally detected the gravitational wave signal by Huaxia's gravitational wave detector.

In the conference room, every physicist and astronomer was very happy. This is an amazing discovery, which will confirm the existence of gravitational waves, and will help physicists study gravitational waves, while astronomers It is helpful to observe the universe with the help of gravitational waves.

Qin Yuanqing did not express any opinions, but looked at the observed data, his mind was running fast, and finally he found that through the data of these signals, it can be determined that gravitational waves exist, which will undoubtedly be the first step for human exploration. The great progress of gravity, the mysterious veil of gravity, has been opened up by human beings to a small corner, and through this small corner, human beings can see more scenery of the gravitational world.

The conference lasted for a whole day, including the naming of the gravitational wave signal, and a large number of papers that followed. Such a discovery alone is enough to produce dozens of world-class papers and hundreds of second-rate papers. These research papers are achievements for these researchers. This is their legacy to the world.

The results of these papers will further demonstrate the correctness of the conch physical model proposed by Qin Yuanqing. In the past ten years, the development of world physics has never deviated from the conch physical model. This undoubtedly represents the greatness of the conch physical model and is also considered It is the greatest achievement of theoretical physics made by Qin Yuanqing!
