Black Holes, which reside in the core of galaxies, are one of the most enigmatic subjects for astronomers and scientists globally. Earlier, scientists believed that black holes play a crucial role in the formation and evolution of galaxies. Now, adding up to this conviction, a team of astronomers has claimed that the Black Holes once paved paths for the escape of light to the earth, creating right conditions for life in the land.
As the scientists claimed, soon after the Big Bang – the largest-scale catastrophic event that caused the evolution of earth; complete darkness engulfed the universe. The incredibly intense and determining event caused the cosmos to churn up an extreme amount of scorching and compressed gas that completely blocked the light on earth. Centuries later may be as many as one billion years after the incident of Big Bang; the universe again started expanding and becoming more transparent. Then it was packed with planets, galaxies, stars, and other objects that emit visible light.
But what was the element or factor which that light up the universe? According to the researchers from the University of Iowa and the Harvard–Smithsonian Center for Astrophysics, it was the black holes which paved the path for the inward light of the sun to the earth, hence constructing the universe which we are witnessing today. As highlighted by the researcher team, the black holes that inhabit in the center of galaxies are responsible for fling out substances so aggressively that the evicted objects penetrated the cloudy surroundings of earth, allowing visible light to run off. The researchers arrived at this conclusion after examining and observing a nearby galaxy, called Tol 1247-232 from which the ultraviolet light is absconding.
As the new theory highlighted, the unusual galaxy Tol 1247-232 has located only 600 million light years away from earth and is one of only three near-earth galaxies that give off Ultraviolet light lights. More explicitly saying, these galaxies emit energetic frequencies of UV light in what is known as the Lyman series. For the study, Philip Kaaret, professor in the UI Department of Physics and Astronomy and co-author of the study alongside his colleagues, examined the near-earth galaxy and tracked down the presence of extremely bright X-ray sources which are more likely to accrete the black holes.
However, the problem is that black holes are more apt to be celestial dust-busters which buff up small fissures in their near environs and clean out an entire galactic enclosure. But they are not responsible for leafing blowers that puff things around, and that’s why astronomers still are not entirely sure how a black hole blustered things in the early universe instead of sucking them. Now the lead researcher Philip Kaaret is planning to make some further studies on Tol 1247-232 and also the nearby galaxies that are emitting ultraviolet light so that his latest theory can be corroborated.
