Melbourne: Experts have claimed that the notion black holes become supermassive by merging with other black holes is much more complex than previously believed.

According to theconversation.com, for the study, scientists compared the data with gravitational wave predictions from various theories for how black holes grew.

Experts found that supermassive black holes are bigger than the sum of their parts because when galaxies collide, they form a new, bigger galaxy.

According to the researchers, colliding galaxies` black holes sink to the centre of this new galaxy and orbit each other, eventually combining to form a new, bigger black hole.
