The media released the black hole delayed short film for the first time. What message does the short film convey?

Due to the complex dynamic process around the black hole, the matter in the accretion disk of the black hole will rotate at high speed, and the brightness difference will appear in the observer's field of vision under the Doppler effect, so people can see that the brightest place of this orange-red ring will change constantly. ?

On September 25th, according to relevant media reports, scientists have now gone one step further and launched a time-lapse photography animation of black holes.

They sorted out the black hole shooting data since 2009. Because there were few telescopes available in the early days, the photos taken were also lacking. Scientists have to rely on the data of 20 17 to fill some gaps.

In 20 19, the first black hole photo in history was released. According to the new research in the Journal of Astrophysics, experts have constructed a new mathematical model, reconstructed the evolution process of black holes from 2009 to 20 17 years by using the low-resolution data collected many times earlier, and constructed this short film showing the dynamic process of black holes.

Data show that black holes are celestial bodies existing in space in modern general relativity. The gravity of a black hole is extremely strong, which makes the escape speed in the event horizon faster than the speed of light. So? A black hole is a celestial body in the curvature of time and space. It is too big for light to escape from its horizon? . A black hole is a celestial body with infinite density and infinitesimal volume in space, and all physical theorems will be invalid when encountering a black hole. Is it caused by a star of sufficient mass running out of fuel in the nuclear fusion reaction? Death? After that, gravitational collapse happened. ?

19 16, German astronomer Karl? Schwarzschild obtained the vacuum solution of Einstein's field equation by calculation. This solution shows that if the actual radius of a static spherically symmetric star is less than a fixed value, there will be a strange phenomenon around it, that is, there will be an interface horizon. Once you enter this interface, even light can't escape. This fixed value is called schwarzschild radius, this? An incredible celestial body? By American physicist John? Archibald. What's Wheeler's name? Black hole? . ?
