Black holes may form immediately after the Big Bang

A team of astronomer proposed that how did supermassive black holes form and What is dark matter, both these questions will be solved with an alternative model for how the universe came to be. The astronomers proposed that these cosmic mysteries can be answered by the so-called “primordial black holes.”

Nico Cappelluti from University of Miami, ESA Science Director Günther Hasinger and Priyamvada Natarajan from Yale University has suggested that since the beginning of the universe, the black holes existed. These primordial black holes can be the unexplained dark matter. The research paper has been published in The Astrophysical Journal.

Scientists explained that black holes of different sizes are still mysterious. They do not have an explanation for how supermassive black holes have grown so big in the relatively short time.

ESA astronomers also suggested that there might be small black holes as well. If this is true, then the small black holes were created from dying stars.

The new research will show without applying new particles or new physics, scientists will be able to solve mysteries of modern cosmology such as the nature of dark matter to the origin of super-massive black holes.

If the black holes were created immediately after the Big Bang, they should have merged in the early universe and could have made more and more massive black holes over time. LISA, ESA’s future gravitational wave space observatory, must have picked up the signals of those mergers if the primal black holes existed. Small black holes can be the primordial black holes that did not merged into larger ones yet.

According to the new research, the universe should have filled with black holes all over. Stars will form around these ‘dark matter’. Then it will create many solar systems and galaxies over billions of years. If the first stars created around primordial black holes, then they must have existed in the universe earlier, than it is seen in the ‘standard’ model.

Scientists say, if the primordial black holes existed then they must have the seeds from which all black holes were created, even the black hole in the centre of the Milky Way.

ESA’s Euclid mission will show the dark universe in greater detail. This mission will play a vital role in identifying primordial black holes as dark matter candidates.

The upcoming James Webb Space Telescope which will look back over more than 13 billion years will be shading further light in the mystery.
