That's what people say, but we have no actual … WebJul 6, 2024 · No, there is no theoretical maximum limit for the mass of a black hole. In practice, one could argue that a black hole's mass can't exceed the total mass of the Universe, but defining what one actually means by "total mass of the Universe would be complicated". If two black holes merge, they simply form a larger black hole.
