Astronomers have suggested the existence of incredibly large black holes (SLABs) that are larger than the supermassive black holes at the centers of galaxies. This is reported in an article published in the Monthly Notices of the Royal Astronomical Society. The research is summarized in a press release on Phys.org.
It is believed that there is some upper limit to the mass of large black holes due to the way they form and grow. Supermassive black holes reach a mass between a million and ten billion times the mass of the Sun by absorbing stars and gas from the surrounding area. However, in a new work, scientists have discovered that SLABs formed in a different way in the early universe, even before the appearance of galaxies. However, there is currently no evidence for the existence of these exotic objects.
Earlier it was reported that an international team of scientists from the United States and Germany discovered a supermassive black hole located at a distance of 13 billion light years from Earth. It formed approximately 690 million years after the Big Bang, during the reionization era, when quasars and the first stars appeared.
