The Universe, in its unparalleled beauty, has always given us such great sites. We have neutron stars, and horse-shaped nebulas, we have pulsar and constellation. And then black holes happened. We do not exactly think that they’re the bad guys of the galaxies, but there’s not exactly friendly. Black Holes should probably go on a diet because most of them tend to eat more than they can chew.
Now, on to more science facts. Black holes, the bad boys of the galaxy, are considered to be geometrically defined areas in space-time or even ruptures. In such spatial areas, the gravitational forces are so intense that even light can escape its pull.
According to various studies on the subject, it would seem that a black hole is able to sustain its morphology by siphoning gas from the nearby gas disks.
Professor Andrew King, a fellow astrophysicists from the University of Leicester has taken a keen interest in this celestial phenomena. King wants to understand what makes a black matter tick. He explains that in the center of our galaxies, there are supermassive black holes.
In the surrounding area, gas tends to conglomerate, forming rings or disks around these black holes. As a result of this process, the black holes extract gas from the disks which they use it in order to expand.
King managed to do the math and reached an astounding conclusion: before running out of fuel, or gas for that matter, a black hole is able to expand up to 50 million times the mass of our Sun. The scientists said that 50 could be the upper limit in terms of black hole expansion.
The British astrophysicist also said that a black hole might very well keep on growing if would come across other food sources, so to say. He added that there are two possible scenarios in which a black hole could continue to grow after it exhausted all the gas from the surrounding disks.
In the first scenario, the black hole would continue to expand if a passing star would fall into its grasp. Lastly, the bandit of the galaxy can continue to grow if he was to merge with another black hole, thus creating a new and bigger one.
King also added that several black holes of these dimensions have been researched in the last couple of years by taking a look at the radiation given off by gas disks, as the black hole begins to siphon them. He also said that there are other methods which we can use in order to study black holes such as light bending or gravitational waves.
