Researching the 'dead sound' of black holes
The gravity of the black hole is so strong that even light cannot escape, turning them into dark objects that never emit any form of radiation.
British astronomers say deadly sounds from black holes can reveal their birth history.
Experts can find out when black holes are discovered
they collide with each other and emit gravitational waves
The gravity of the black hole is so strong that even light cannot escape, turning them into dark objects that never emit any form of radiation.
However, when colliding with other black holes or 'swallowing' unhappy stars, a black hole will emit a form of radiation called gravitational waves, which Einstein predicted for nearly 100 years, According to Cardiff University researchers (UK).
These waves spread in the space-time structure at the speed of light, but were difficult to detect, according to the BBC.
Sensors from the US, Europe, Japan and India can detect gravitational waves traveling within the same frequency range as sound waves, serving as microphone devices that hear this particular type of wave.
Finding gravitational waves through space - the time of a black hole and measuring its frequency can reveal the mass and rotation of this black hole without having to go near that "hungry giant" .
In addition, by comparing the weak strength of two different sounds when black holes clash, experts can not only understand the last surviving black hole, but also know the components of the black hole pair. join the initial encounter, according to expert Ioannis Kamaretsos.
