Astronomers have suggested the existence of incredibly large black holes (SLABs), which are larger in size than the supermassive black holes in the centers of galaxies. This is reported in an article published in the journal Monthly Notices of the Royal Astronomical Society.
It is believed that there is some upper limit to the mass of large black holes because of the way they form and grow. Supermassive black holes reach masses between a million and ten billion solar masses by absorbing stars and gas from their surroundings. However, in new work, scientists have revealed that SLABs formed in a different way in the early Universe, even before galaxies appeared. 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 U.S. and Germany discovered a supermassive black hole located 13 billion light years from Earth. It was formed about 690 million years after the Big Bang, during the era of reionization, when quasars and the first stars appeared.
