Take the earth as a gravitational wave detector?That’s right!The reporter learned from the Institute of High Energy Physics of the Chinese Academy of Sciences on the 14th that the researchers from the reason and the Hong Kong University of Science and Technology proposed a new experimental plan in high -frequency gravitational wave detection.they think,Planets with magnetic layers, such as Earth and Jupiter, can be used as a giant detector that detects high -frequency gravitational wave signals.Related research results were published in the Physics Review Express.

The so -called gravitational waves are actually time -space changes produced by material and energy.If the water surface is used to metaphorize time and space, the gravitational wave can be regarded as the ripple of time and space.High -frequency gravitational wave refers to the gravitational waves that are much higher than Kurzz.
　　

In 2015, the laser interference gravitational wave Observatory (LIGO) successfully detected gravitational waves and opened a new window for observation of the universe.Different from electromagnetic waves, gravitational waves are weakly interacted with material. The detection may reveal the mysterious veil of dark energy and dark matter, and can present a more complete cosmic picture.

This time,For the first time, scientific researchers proposed that the planets of the solar system are used as a laboratory for detecting high -frequency gravitational wave signals, and the signal photon generated by the scientific satellite detection gravitational waves surrounding the planet’s scientific satellite detection of gravitational waves.“Considering the range of electromagnetic bands of astronomical observation and detection, this scheme can cover a wider gravitational wave frequency band. Compared with other detection schemes, this solution also has high magnetic field strength definitation, gravitational wave-photon conversion valid path length, signal fluxThe advantages of the corner distribution. “One of the” author of “the paper, Liu Tao, an associate professor of Hong Kong University of Science and Technology.
　　

The results of the study show that using existing low -orbital earth satellite data, the planetary magnetic layer system can already give stronger restrictions on high -frequency gravitational waves within a wide range of frequency, covering the gravitational wave frequency band that has not been involved before the blockbuster.
