If ‘stupendously large’ black holes, those with masses more than 100 billion times that of the Sun, exist in the Universe, they would provide a powerful tool for cosmological tests due to their unique imprints, according to a paper published in the Monthly Notices of the Royal Astronomical Society.
“Black holes are a key prediction of general relativity,” said Queen Mary Emeritus Professor Bernard Carr and colleagues.
“There are a plethora of observations indicating their existence in the solar or intermediate-mass range. In particular, the existence of binary black holes in the mass range between 10 and 50 solar masses has been demonstrated by the detection of gravitational waves from inspiralling binaries.”
“There is also evidence for supermassive black holes at the centers of galaxies, including Sagittarius A* at the center of our own Milky Way Galaxy, with a mass of 4 million solar masses.”
