The headquarters of Ren Zhenfei's company is in Guangdong Province, and when he heard that Lu Qiujian is now in Guangdong Province, he can still sit there! After immediately dealing with the matter here, he flew back to Guangdong Province overnight, planning to take advantage of this opportunity to build a relationship with Lu Qiu! If Professor Lu was in a good mood for a while and was willing to visit his own company and give a few words of advice by the way, his company would make a lot of money!

However, Lu Qiujian's assistant's mobile phone could not be reached, and Ren Zhenfei did not have Lu Qiujian's phone, so he had to try his best to inquire from the side! What was a little relieved was that Lu Qiujian did not keep his itinerary secret when he came to Guangdong Province this time, and he soon found out that Lu Qiujian was now at Yat-sen University for exchanges! So he hurriedly brought someone to find him.

Mr. Ren came to the door, and the president of Yat-sen University immediately came to greet him in person! The other party gave face to Ren Zhenfei and did not want to meet him empty-handed, so he signed a check and donated it to Yat-sen University to set up a special scholarship, and then asked about Lu Qiujian's news, "President, I heard that Professor Lu is now on exchange at your school? I wonder if you can let me meet Professor Lu?"

Tsk, the principal looked embarrassed, and after a while, he said hesitantly, "If it were another time, I would always have to help find a way if Mr. Ren spoke!

Well, I have donated a lot of money just now! Why is the principal still like this? Could it be that Professor Lu really has something important? But since he has come, he is always unwilling to see him! So Ren Zhenfei pretended not to see the president's embarrassed expression, and continued to ask, "Oh? What is Professor Lu busy with now?"

"This can all start from when Professor Lu first returned to China! As soon as he returned to China, Lu Qiujian urged the government to invest in the Tianqin Project! He also joined forces with Beijing Normal University to build a brand-new gravitational wave observatory in our school! This observatory was formulated by Professor Lu from its theoretical design to its work process! Two days ago, it seemed that something had been discovered in the observatory, so he specially called Professor Lu to invite him! Speaking of this, the principal couldn't help but show an excited look, "If gravitational waves are really discovered this time, this will be a Nobel Prize-level achievement!" ”

Since Beijing Normal University won the Fields Medal and the Nobel Prize in succession at Lu Qiujian, it has stubbornly suppressed Mizuki University for several years! If the gravitational waves were really confirmed at Yat-sen University this time, wouldn't our school's ranking be able to rise several places in a row? Now is the critical moment for research, and the president will not let others disturb Lu Qiujian if he says anything, and if it weren't for Ren Zhenfei who sent a large check as soon as he came up, he probably wouldn't even reveal the news.

But since Ren Zhenfei came, he was reluctant to leave like this, so he had to sign a check again and hand it to the principal, "We have always supported research in the basic field for Hua Company, and this little meaning should be regarded as a reward for the staff of the Tianqin Project! Thank them for their silent efforts for the progress of basic science and technology in China over the years!"

"Your years of hard work have finally paid off today!" At the same time, in the office of the Gravitational Wave Observatory of Yat-sen University, Lu Qiujian raised his head from a large number of jù and said with a smile, "After my verification, the signal you observed three days ago is exactly the gravitational wave signal generated by the merger of two superstellar black holes with a mass of 31 times the solar mass and 42 times the mass of the Sun 1.26 billion light-years away!"

"I know! I know!" Director Guo of the Department of Physics of Beijing Normal University has been in tears, and it has been more than four years since Lu Qiujian returned to China to win the project of the Gravitational Wave Observatory! He has devoted half of his time to this project, and the hard work of thousands of **** nights and nights has finally paid off today.

"I never dared to believe that I would be so lucky, but I didn't expect to see gravitational waves confirmed with my own eyes in my lifetime!" Academician Luo, the person in charge of Sun Yat-sen University of the Tianqin Project, was also very excited and couldn't help himself; Director Guo had just waited for more than four years, and it has been decades since Sun Yat-sen University advocated the study of gravitational waves! Academician Luo has been consumed from a young scholar to an old man, and to be honest, his investment in this area is much greater than that of Director Guo, and of course his mood will be even more excited!

In 1916, the year after Einstein proposed the gravitational field equation, he proposed the famous gravitational wave prediction: 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 cross-sectional direction and squeeze space-time (objects) in a perpendicular direction.

Einstein's writings on gravitational waves are still preserved in the Einstein Archives in Jerusalem! For nearly 100 years, there was a fierce debate in the physics community over whether gravitational waves existed, and scientists did calculations and found that the amount of compression and extension of gravitational waves is extremely small, "fractional of the diameter of an atom." In other words, it's hard to spot.

American physicists Joseph Hutton-Taylor and Russell Allen-Hulse jointly observed the pulsar binary system PSRB1913+16 and discovered the first indirect quantitative evidence of gravitational waves, for which they were awarded the Nobel Prize in Physics in 1993.

The California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT) jointly launched the Laser Interferometer Gravitational-Wave Observatory (LIo), also known as Ligo, using $394 million from the National Science Foundation to build two 4-kilometer-long vacuum tube transmitters in Livingston, Louisiana, and Hanford, Washington, for gravitational wave detection.

Under the impetus of Lu Qiujian, the Chinese government also spent $350 million to restart the Tianqin project and built a gravitational wave observatory according to Lu Qiujian's design.

"We're really lucky! For such basic research, more than four years is simply too cost-effective!" This is different from the discovery of dark matter using LHC, when dark matter particles were produced and then carried out on the backbone side, and the Tianqin project was to explore the vast universe, and whether or not it can be found is a matter of luck.

"According to international practice, this gravitational wave signal will be named GW110922!" GW is the abbreviation of gravitational waves, and 110922 is the date when this signal was discovered!"Next, let's sort out the number jù and write it into an article and send it out!" (To be continued. )
