Black holes are those places in space where extremely high gravitational energy is present. Nothing can pass through them, not even light can pass through them. Black holes have always been one of the most mysterious things in astronomy, and their origin has been the biggest question. Scientists speculate that supermassive black holes may have formed from primordial black holes that came into existence just after the Big Bang.
How was the universe created? In an alternative model, a team of astronomers proposes that both supermassive black holes and dark matter can be understood by so-called ‘primordial black holes’. His model suggests that black holes have existed since the beginning of the universe. In a study published in The Astrophysical Journal, researchers said that if most black holes formed soon after the Big Bang, they could begin to merge in the early universe, creating more and more massive black holes over time.
If there are big black holes, there can be small ones too.
Study co-author Günther Hasinger says that black holes of various sizes are still a mystery. We do not understand how supermassive black holes can become so massive in the relatively short time available after the universe came into being. The study also points to the fact that if supermassive black holes do exist, there may be very small black holes. Small black holes can only be primary black holes that have not yet merged into larger black holes.
Will the universe be filled with black holes?
Citing the study, the European Space Agency said that according to this model, the universe would be filled with black holes everywhere. American astronomer Edwin Hubble first observed in the 20th century that galaxies were moving away from us. The farther they are going, the faster they are going. This discovery confirmed that the universe is expanding, although scientists have been unable to explain the factors behind it. A team of international researchers from across the US has made a startling discovery based on the 100-year-old Hubble theory.
Black holes increasing their size
Researchers from the University of Hawaii at Manoa, the University of Chicago and the University of Michigan in Ann Arbor believe they have solved the puzzle of the universe. In a new research published this month in the Astrophysical Journal Letters, scientists propose that black holes may become more massive as the universe expands. Black holes absorb the light coming towards them, so they cannot be seen with the naked eye. Some black holes can be 50 to 100 times larger than the Sun.
