A team of astronomers from the MIT (Massachusetts Institute of Technology) managed to change the time when a black star swallowed a star into sound. In a voice available on Monday (2/5) by the school, he was able to hear a strong voice that distinguished between low and high voices, which, in fact, is the reproduction of echoes of light emitted by large gravitational wells. Inhale and exhale dust from orbiting stars. Listen:

Recording is a generation of the sound waves of the emission of light echoes, called X-ray echoes, which cause the moment when a black hole swallows a star. The transition to sound has not been achieved with the help of music and academic research at MIT.

How capture and conversion is accomplished

To capture this moment, scientists used NASA’s Nicer telescope, a high-resolution X-ray device in the International Space Station. The device detected 26 black hole x-ray machines, and 10 of them were located near the sunglasses they had chosen for observation because they were in the best position to detect and detect ncha.

Eight of the 10 machines were not previously known. The movements were clearly captured. First, the black hole, dark and invisible, hardens, and causes the corona of large energy photons with the plane of the material – the beginning of light echo; The gravitational effect then emits a high-energy flash and then the result returns to the “soft” low energy state and returns to black.

The flash is the end of the devouring process and leads to an expansion of the area of ​​the high plasma energy outside the black hole. The scientists then transformed the echo process into a sound wave.

In the audio simulation video, the white circle is the center of the black hole where the event occurs and the light echoes are the color of the wave. Each color represents light echoes, as the energy emitted from the black hole. Echoes with lower frequencies are lower and those with higher frequencies are higher.

Discovery is part of another project

The study, which allows the formation of a black hole at the time it devours the star, is part of a study that has scoured satellite data for signals from black holes echoes to rehabilitate the immediate area of ​​the gravitational wells.

By observing the explosion of black matter, scientists have found that their role in the evolution of galaxies is significant, but little understood by modern astrophysics. “Fortunately, these binaries look like ‘mini’ supermassive black holes, and so by understanding the cracks in the small holes nearby, we can understand that the cracks are similar. in the vast black holes affecting the galaxies in which they live, “explains physics professor from MIT, Erin Kara.

In addition to Kara, Jingyi Wand, a graduate of the institute, and Matteo Lucchini and Ron Remillard also participated in the study. NASA is also involved in education.
