Black hoes are the most mysterious objects in the universe. Very few people know about them. One black hole can suck their surroundings empty and still have enough room for anything that wanders near it. Pray that there’s none within few light years from our planet or else we all be goners. Two colliding black holes will release an energy that is beyond calculation.
However there’s nothing to worry about. This report will keep your mind at ease.
What is a black hole anyway? It’s a place in the outer space which has a very strong gravitational force that nothing escapes it, not even light. It’s invisible to the eyes.
How are they formed? Imagine a very huge star with its middle collapsing upon itself. That’s what black holes are.
It’s no secret, at least for scientists and astronomers, that in every galaxy, ours included, there exists a black hole. Okay don’t get excited now. These phenomes have a mass of equivalent to millions or billions of suns or stars for that matter. Billions of our sun will easily fit inside one black hole. Our sun is considered medium size.
These humongous black holes behaves like vacuum cleaners. They will suck anything around them not even light particles can escape. They develop together with their host galaxies according to researchers. When they start sucking the gasses in their surroundings, they form a disk like object aptly called the accretion disk. The result is the formation of quasars.
“Quasars are valuable probes of the evolution of galaxies and their central black holes,” comments California Institute of Technology professor of astronomy S. George Djorgovski. “If we can systematically study a large population of quasars, we can discover rare and unusual phenomena that can help us better understand the overall picture of their evolution.”
The data would be very useful and will play a crucial role for us to better understand the role of black hole mergers in the continuing evolution of or galaxy.
“Until now, the only known examples of supermassive black holes on their way to a merger have been separated by tens or hundreds of thousands of light-years,” Stern comments. “At such vast distances it would take many million, or even billion, of years for a collision and merger to occur. In contrast, these black holes are at most a few hundredths of a light-year apart, and could merge in about a million years of less.”
