Big black holes

It looks like black holes can grow to be as massive as 50 billion suns. How massive is that? It’s approximately 99 duodecillion kilograms….which is a 99 followed by 39 zeros. (Put another way, if you had 99 duodecillion dollars, you could buy as many PlayStation 3s as you wanted. Blows your mind, right?)
