The Chinese scientific research team observed the M87 black hole spin for the first time, which is in line with the prediction of Einstein's general theory of relativity.
Comprehensive Xinhua News Agency and CCTV news reports, the International Journal Nature Natural Wednesday (September 27) published a papers led by Chinese scientists., The swing cycle is about 11 years, and the amplitude is about 10 degrees.This is another achievement in the field of black holes in the field of black holes after the first black hole "donuts" photo and the release of black holes in April this year.
The first author of the paper and the author of the communications author, the post -doctoral of Zhijiang Laboratory Cui Yuzhu. In the process of analyzing the M87 black hole spray structure, the scientific research team found that the M87 black holes jet showed cyclical swinging.The theory provides observation evidence.This phenomenon is in line with Einstein's general theory prediction that "if the black hole is in a rotating state, it will cause the reference system to drag effect."
Lin Weikang, an associate researcher at the Southwest Astronomical Research Institute of Yunnan University, said that although the self -spin is the infrastructure of the black hole theory, there was no direct observation evidence to confirm it before.The research successfully linked the M87 black hole spray dynamics with the large -quality black hole status of the galaxy center, providing key elements for further unveiling the mysterious veil of the black hole.
Public information shows that the observed black hole is located in the center of a giant ellipse galaxy M87, which is observed, 55 million light years (about 9.46 mega kilometers in one light years), and the quality is about 6.5 billion times the sun.EssenceIn 2019, a scientist released the M87 black hole image taken by the Event Far Telescope (EHT) for the first time. This is the first time that the black hole is observed in the form of photos in human history.
