Did black holes form immediately after the Big Bang? Latest answer from ESA
News! After many years of study and various discussions about the existence of black holes since the beginning of the Big Bang or not, ESA has suggested a clear answer. ESA, along with Nico Cappelluti (University of Miami), Günther Hasinger (Director of ESA Science) and Priyamvada Natarajan (Yale University) suggest that black holes have existed since the beginning of the Universe, right after the Big Bang.
However, according to the study, the first black holes could themselves be the as-of-yet unexplained dark matter. "Black holes of different sizes are still a mystery. We don't understand how supermassive black holes could have grown so huge in the relatively short time available since the Universe existed, "Günther Hasinger said in an ESA article. The whole study, published by ESA, shows that there could have been very small black holes, so they could not be made of stars. That would explain everything, because the stars formed after black holes, as you can see in the image above.
But then, we should ask ourselves what caused the formation of these stars. It is clear that most likely the first black holes were smaller than the current ones, plus they had dark matter in them, not being matters of great dimensions at that time. "Our study shows that without introducing new particles or new physics, we can solve mysteries of modern cosmology from the nature of dark matter itself to the origin of supermassive black holes," says Nico Cappelluti in an article published by ESA.
The European space agency's explication is that if black holes formed right after the Big Bang, more and more black holes began to fuse in the early universe, leading to the creation of more and more things in the universe. Thus, more and more black holes began to appear in the universe, and stars to form around "dark matter". And then they started creating solar systems and then galaxies. But all this has happened in billions of years. LISA will be an ESA space observatory and will be launched somewhere in 2037. In line with ESA, LISA will see far beyond the James Webb Telescope, meaning it will be able to capture information from the first black holes.
"The primary black holes, if any, could be the seeds from which all black holes are formed, including those in the center of the Milky Way," says Priyamvada Natarajan. The James Webb Telescope developed by NASA, ESA, and CSA, which will be launched on December 24, 2021, will be able to observe more than 13 billion years ago, but most likely will not be able to see the creation of the first black holes. That mission will be for LISA and future telescopes and missions. However, it could see the first galaxies formed, according to ESA. "If the first stars and galaxies had already formed in the so-called 'dark ages', Webb should be able to see evidence of them," adds Günther.
We wish ESA success in their research into black holes and with the launch of the James Webb Telescope a success, which will be live on the Bailey Universe and the space agency's website on December 24, 2021.
