NASA shared: The dance of black holes fascinated


The video of the dance of black holes shared by NASA hypnotizes the viewers … Someone in the image 200 million times bigger than the sun, two black holes half the size of the other orbiting each other.

In the heart of every galaxy nothing can escape black hole is found. Sometimes when two galaxies merge, their black holes lock in and constantly spin around each other. Of NASA published A new animation shows a double orbiting supermassive black hole known as the binary system.

The dance of black holes will end when they unite

In the animation that shows the dance of black holes, the objects are in different colors. The orange one is 200 million times larger than the Sun. The blue one is half the weight of the other. Around both black holes accretion disk There are glowing rings of hot gas and space debris known as. When one black hole moves in front of the other, the strong gravity It disturbs the light from the accretion disk. The black hole in the background is like hitting pieces around the other. After the black holes pass by each other, these distorted pieces flow back together.

NASA astrophysicist who created the image Jeremy Schnittman explained how he did the animation. Using a supercomputer, he calculated, square by frame, how the light from both accretion discs would bend in the dance of black holes. Normally, these calculations take about 10 years on a modern desktop computer. Schnittman completed it in about a day.

In animation, black holes appear smaller as they approach the viewer and larger as they move away. Seen from the side, the accretion disk resembles a rainbow of fire orbiting around the center of the black hole. That rainbow twists as the dance of black holes continues. The accretion disk is also brighter on one side. As a black hole rotates, a cloud of gas and debris rotates around it. Thus, the disc material moving towards our eye is brighter than the material moving away.

According to Schnittman, a pair of black holes, like those depicted in the animation, eventually merge into a single giant black hole. But first of all, they dance around each other for a long time.

NASA shared the animation depicting the dance of black holes on its YouTube channel;

Discovery of gigantic cosmic bodies

Black holes are regions of space where gravity is very strong and nothing can escape, including light. These gigantic massive bodies are filled with matter squeezed into a small space rather than empty space. Physicist Karl SchwarzschildWhile finding a specific solution to Einstein’s theory of general relativity in 1916, he accidentally discovered black holes. He was trying to find a solution to the gravitational force of a single, symmetrical ball of matter like the Sun at the center of our solar system. However, the theory today Schwarzschild radius It showed something strange at a certain radius known as. Later it became clear why this radius is special. If you compress the mass of an object into an area smaller than this radius, gravity will overwhelm every known force and nothing can escape.

At that time, physicists argued that this situation would never be found in nature. Indian physicist in the late 1930s Subrahmanyan Chandrasekhar When he discovered that no force above a certain density could overcome gravity, it turned out that black holes are likely to exist in nature.
