Rebirth of science and technology academic master - Chapter 710

c704 Gravitational wave signal (asking for monthly votes)

On the other side of the Pacific, inside the Pentagon, is the Naval Command!

The Naval Command is one of the three service departments under the United States Department of Defense, also known as the “Washington Navy Yard”. It consists of three units: the Office of the Navy, the Naval Operations Department, and the Marine Corps Headquarters.

At this time, at the Naval Command, an old man was holding a naval meeting. More than a hundred people attended the meeting, each of whom was a powerful figure in the navy.

A man in his fifties 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 this location, we have not received any news from the submarine so far, and we have every reason to believe that the submarine has unfortunately perished.”

“As for whether the nuclear submarine hit an undersea mountain, a sunken ship, or a whale, there is no evidence so far, and I can’t say anything. Everyone is free to use their imagination. After all, any possibility is possible.” The man shrugged and said in a humorous tone.

“Shit, they are too brave. Don’t they know that there is a nuclear reactor 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 document signed by both parties. We are not responsible! At the same time, unfortunately, we have no evidence that they sank the Los Angeles-class nuclear submarine. We say Despite our suspicions, people asked us why we violated the signed documents. How should we explain it?” an old man said 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 you lose one, you will lose one. Those big men won’t Allocate funds to us to build nuclear submarines.” Boris said dissatisfiedly. In the past 16 years, with the commissioning of the USS Carter nuclear-powered aircraft carrier, the total tonnage of the U.S. Navy has not increased but decreased, because some ships have reached the end of their service life and have to decommissioned without sufficient funds to build enough ships to replenish them.

Today, although the Navy has two ocean fleets, namely the Atlantic Fleet and the Pacific Fleet, it also has seven fleets, 12 aircraft carrier battle groups, 12 carrier-based aircraft wings, and is mainly equipped with 60 submarines and 133 large watercrafts. Combat ships, 2,900 aircraft, and 1,500 helicopters may seem powerful, but they no longer have enough dominance.

Even due to financial reasons, the aircraft carrier fleet cannot cruise the oceans as it did in the past. After all, such large surface combat ships are worth money every time they move.

“The new news is very bad. Our funding will likely be cut by another 10%!” Lewis, the old man sitting at the front, said solemnly. He was the commander-in-chief of the Navy Department, and he also experienced the time when the American Navy was at its strongest.

Everyone in the conference room has experienced the era when the U.S. Navy was powerful and invincible. At that time, the size of the Navy was larger than the next ten combined, and it could fight and win two large-scale wars at the same time.

But now, this situation has been broken. This is very angry, but there is no way. After several confrontations, they suffered heavy losses. They had to agree to peaceful negotiations, and then reached an agreement and signed an agreement.

“What? Are they crazy! Do we want all our ships to lie down in the military port?” Trit’s face changed. The annual maintenance and operation costs of such a huge fleet are very high, let alone There is a warrior’s wage.

The current military expenditure is no longer enough to replace warships. If it is cut by another 10%, Tritt can hardly imagine that this will be a disaster.

In the conference room, various scoldings continued. Their interests are the same when it comes to military expenditures. With funds, everyone can be more prosperous. If there are not enough funds, everyone will have to live a tight life. Now they are cutting military expenditures by 10%. This is It was a large number that they found difficult to accept.

In the United States, the most important thing is the navy, which accounts for the bulk of military expenditures. This means that military expenditures will be cut by 10%, and the navy will suffer 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 exploding in the meeting. They were not stupid to get to this position. On the contrary, they were all very smart. They knew exactly what Lewis meant by expressing our voices.

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

Huaxia, Beijing, Qin Yuanqing is attending a special meeting. Basically, the participants in this meeting are theoretical physicists and astronomers.

“Academician Qin, experts and representatives, after careful consideration, the signal observed by the Purple Mountain Observation Center came from the collision of two super-large stars with 30 and 40 times the solar mass, 2.87 billion light-years away. The gravitational wave signal generated by the merger!” the director of the Purple Mountain Observation Center said solemnly.

“I knew it! I knew it!” Director Yang of the Department of Physics of Shuimu University burst into tears. Gravitational wave observation is a profound research, and they have made great efforts for this.

“I have never believed that I would be so lucky. I never expected to see the confirmation of gravitational waves in my lifetime!” Academician Guo of Yanda University was equally excited.

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

In 1916, the second year after Einstein proposed the gravitational field equation, he proposed the famous prediction of gravitational waves: changes in the gravitational field propagate in the form of waves at the speed of light, 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 the vertical direction.

Today, Einstein’s article 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 surrounding the existence of gravitational waves. Scientists have done calculations and found that the amount of compression and expansion of gravitational waves is extremely small, “a fraction of the diameter of an atom.” In other words, it’s hard to detect.

However, in the face of such challenges, physicists did not give up. American physicists Joseph Hooton-Taylor and Russell Allen-Hulse jointly observed the pulsar binary system PSRB1913+16 and discovered gravity for the first time. They received the Nobel Prize in Physics in 1993 for their indirect quantitative evidence of the existence of waves.

The California Institute of Technology and the Massachusetts Institute of Technology in the United States have jointly launched the Laser Interferometer Gravitational Wave Observatory project – also known as LIGO. They used US$394 million sponsored by the National Science Foundation of the United States to conduct research in Livingston, Louisiana and Washington, D.C. In Hanford, Texas, two 4-kilometer-long vacuum pipeline launchers were built for the detection of gravitational waves.

On February 11, 2016, the LIGO Scientific Collaboration and the Virgo Collaboration team announced that they had used the advanced LIGO detector to detect the gravitational wave signal from the merger of dual black holes for the first time. In the early morning of June 16, 2016, the LIGO collaboration team announced that at 03:38:53 on December 26, 2015, two gravitational wave detectors located in the Hanford District of the United States and Livingston, Louisiana, simultaneously detected gravitational waves. A gravitational wave signal; this is the second gravitational wave signal detected by humans after LIGO detected the first gravitational wave signal on September 14, 2015.

On October 16, 2017, scientists from many countries across the country held a press conference simultaneously, announcing that for the first time mankind had 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 the Qin, Yuan and Qing Dynasties perfected string theory and proposed the conch physical model, theoretical physicists subsequently discovered that the previously observed gravitational waves were controversial and not direct evidence. It is considered as evidence of distance of gravitational waves. After all, black holes don’t even exist, so the original rhetoric is naturally not believable.

Since then, physicists and astronomers have continued to observe the universe, hoping to obtain direct evidence of gravitational waves and prove their existence.

And this exploration is what happened in the past ten years, and the gravitational wave signal was finally detected by China’s gravitational wave detector.

In the conference room, every physicist and astronomer was overjoyed. This is an incredible discovery. It will confirm the existence of gravitational waves and will help physicists study gravitational waves, while astronomers It helps 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 rapidly. Finally, it was discovered that through the data of these signals, it can be determined that gravitational waves exist. This will undoubtedly be the first step in human exploration. A great progress in gravity, the mystery of gravity has been opened to a small angle by humans. Through this small angle, humans can see more of the world of gravity.

The conference lasted a whole day, including the naming of gravitational wave signals 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 the wealth they left to the world.

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