The "ringing" of the black hole, which emitted weak gravitational wave tones after the merger, supports Einstein's theory of relativity even more.
- Researchers have discovered sounds that emanate from a black hole.
- The discovery confirms a theory by Albert Einstein from 100 years ago
- The merging of black holes emits gravitational waves that reverberate at certain sounds.
- The waves could influence future research on black holes.
Yet another theory of the black hole set up by Albert Einstein more than 100 years ago was proved by astrophysicists.
An Analysis of Gravitational Waves from the Beginning The ever-discovered cluster of black holes has recorded sounds that researchers called "ringing" – a phenomenon predicted by Einstein's general theory of relativity.
"It used to be thought that these sounds were too weak to be recognized, but now we can," said the co-author of a study in Physical Review Letters and an associate professor at Stony Brook University, Will Farr, in an explanation.
"Just as the measurement of atomic spectra in the late 19th century ushered in the era of star astrophysics and the classification and understanding of stars, this is the beginning of the era of black hole spectra and the understanding of black holes and the general theory of relativity, which hides behind it. & # 39;

Researchers were able to discover the sound by re-analyzing the data from the black hole classified fusion GW150914 – the same fusion used in 2015 for the first gravitational wave discovery – and from data from other combined simulations of fusions.
They say that the following combined object starts to wobble when two black holes converge, much like a bell hit.
These vibrations emit gravitational waves – oscillations in space-time – – which reverberate at certain sounds and eventually subside when the fusion ceases.
While some theories suggest that ringing depends on the mass and vibration of the black hole, other scientists have assumed that quantum mechanics also plays a crucial role.
] This year has been particularly fruitful for researchers seeking black hole secrets. The first photo was taken in April.
Binary black holes like those pictured The above was the focus of the recent research study, as strong gravitational waves were emitted.
In an article published in May, scientists affirmed Stephen Hawking's theory, Hawking Radiation, which suggested that black holes emitted from their surfaces due to radiation emit a mixture of factors related to quantum physics and gravity.
The latest discovery of "wrinkling" black holes will likely help researchers obtain even more information about the phenomenon, especially in conjunction with data from the laser interferometer gravitational wave. LIGO, observatory, which was the first device to detect gravitational waves.
WHAT IS INSID EA BLACK HOLE?
Black holes are strange objects in the universe that take their name from the fact that nothing escapes their gravity, not even light.
If you venture too close and cross the so-called event horizon, at the point where no light can escape, you will also be caught or destroyed.
With small black holes, you would never survive such a close rapprochement anyway.
The tidal forces near the event horizon are enough to stretch any matter until it is nothing but a series of atoms.
But for large black holes, like the supermassive objects on the nuclei of galaxies like the Milky Way, which weigh tens of millions if not billions of times the mass of a star, crossing the event horizon would be uneventful.
Because it should be possible to survive the transition from our world to the black hole world, physicists and mathematicians have long wondered what this world would look like.
They have turned to Einstein's general relativity equations to predict the world in a black hole.
These equations work well until an observer reaches the center, or singularity, where in theoretical calculations the curvature of space-time becomes infinite.
