Galaxies Quotes

“A black hole with the mass of the Sun would take 1066 years for this to occur, even if it never swallowed any outside matter along the way. A black hole with the mass of a galaxy will evaporate in 1099 years, and even a hole containing the mass of a supercluster of galaxies – the biggest ever likely to form – will be gone in 10117 years. That”
