Today, the major layouts have been refreshed by “gravitational waves”, and wherever the eyes are, they are all related to “gravitational wave discovery”. It turned out that the incident originated from a number of scientific institutions in the United States and Europe who announced on the 16th the discovery of “gravity waves that have never been observed before”. According to the news, the National Science Foundation issued a press release stating that a press conference was held at 22 o’clock on the 16th to introduce the US “laser pointer interference gravitational wave observatory” and the European “Virgo” gravitational wave detector and their global partners. New discoveries.
What are gravitational waves? The first time humans touched gravitational waves was Einstein’s theory of relativity. After the introduction of Einstein’s theory of general relativity, this theory describing “space-time and matter” has been experimentally tested in many places. People have been stunned by the profound and correctness of this great theory over and over again with solid experimental evidence. However, gravitational waves, an important prediction of general relativity, have not been found for a long time. To detect this gravitational wave, several generations of scientists have made many attempts and efforts. So what exactly is a gravitational wave?
Some people describe the green laser pointer gravitational waves as “ripples of time and space” and believe that black holes are celestial bodies of great mass. Because the mass is very large, according to “the matter tells how space-time bends,” the surrounding space-time will definitely bend very hard. When the time and space are not curved, it is like a calm lake. You gently put a ball on it, and the water surface under the ball is an arc. This is just like the existence of black holes and the bending of nearby space-time. Just a ball stopped on the water, the water was still calm.
