NASA released a black hole recording, breaking the sound of humans that cannot hear the space in space

Science Fiction Network August 24th (Liu Yazhu) The space space outside the earth's atmosphere is called space. The space far outside the earth also contains danger in addition to the beautiful space. The asteroid impact, the comet fall, and even the black holes invading.

Scientists agreed that all this was silent because humans could not hear any sound in space. The spread of sound requires a medium. The space is a vacuum environment. Without the vibration of the medium (solid, liquid, and gas), the sound of sound cannot be achieved in the universe.

In fact, although human beings cannot hear through their ears, they can still use tools that can be captured on the spacecraft and other tools that can be captured. Scientists can convert the radio signals captured by these instruments into sound waves, becoming a sci -fi that humans can hear can be heard The weird or horrible sound.

According to CCTV News, recently, NASA released a audio of black holes recording, which was synthesized by the pressure wave released by the black hole in the British Fairy Troupe. Astronomers said that the sound in the black hole was about 57 octa -degree sounds below the central C, and the human ears could not hear.

Scientists explained that there is no sound in space. Many galaxies are bright X -ray sources. Among them, X -ray radiation is issued by high -temperature gases bound by strong gravity potential, so the galaxy group in the universe exists with gas. Humans can capture the pressure waves from black holes through technology to cause ripples in the star group, and then increase the waveform frequency through technical means, so that people can hear the sound of black holes.
