Black holes can be 50 billion times more massive than the Sun.

Black holes can only grow to the limit of 50 billion solar masses before losing their energy source and stopping growth.

The International Business Times reported that a researcher from the University of Leicester, England, analyzed the disk of gas surrounding the supermassive black hole in the middle of the galaxy. He found that the gas plates are unstable, can lose energy and melt when the outer edge of the black hole reaches a certain length.

"This finding is significant because it shows that black holes have almost reached their maximum mass , " said Andrew King, the study's author. " The mass limit means that there will not be a much larger black hole than the present because there is no equivalent gas disk."

According to a study published Dec. 9 in the British Royal Astronomical Society's monthly edition, once a black hole loses its gas disk, it will stop growing and its maximum mass is 50 billion times greater. God. However, black holes can continue to grow in a different way without the need for a separate gas disk, King said.

"In principle, the mass of black holes may be larger. For example, a near-maximum black hole may merge with another black hole, producing a larger black hole," King asserted. . The merged black holes will not have gas disks, so they cannot be detected by conventional methods.

Traditionally, scientists have discovered black holes from the Earth through gas disk analysis. Gas molecules rotate around the black hole so quickly that it produces heat and emits X-rays. Researchers on Earth can detect X-rays, which determine the existence of black holes. The merged black hole was found by considering the light being bent when it came too close to the black hole.

In our galaxy there are about 100 million black holes. The Hubble telescope estimates that there are 100 billion galaxies in the universe, with 10 billion black holes in existence and a new black hole every second.
