Passage: 1040 (10 duodecillion) years to approximately 10100 (1 googol) years, up to 10106 years for the largest supermassive black holes After 1040 years, black holes will dominate the universe. They will slowly evaporate via Hawking radiation. A black hole with a mass of around 1 M☉ will vanish in around 2×1066 years. As the lifetime of a black hole is proportional to the cube of its mass, more massive black holes take longer to decay.  A supermassive black hole with a mass of 1011 (100 billion) M☉ will evaporate in around 2×10100 years.The largest black holes in the universe are predicted to continue to grow. Larger black holes of up to 1014 (100 trillion) M☉ may form during the collapse of superclusters of galaxies. Even these would evaporate over a timescale of up to 10106 years.

Question: which ones takes more time to decay?
massive black holes
