How do supermassive black holes form?
A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions, of times the mass of the Sun (M ☉).
A supermassive black hole (SMBH) is an extremely large black hole, on the order of hundreds of thousands to billions of solar masses (M ☉), and is theorized to exist in the center of almost all massive galaxies.

It’s impossible to observe a black hole directly, because — as their name suggests — they don’t emit any light or other radiation. But they can be detected via their gravitational effect on visible stars in their neighbourhood, which orbit around the black hole much faster than they would around a normal object of similar size. By measuring the spe...
Rather than devouring anything that ventures too close to them, the black holes at the centers of most galaxies only give away their existence through subtle effects on nearby stars. In an active galaxy, however, the supermassive black hole behaves a lot differently. When surrounded by a swirling "accretion disk" of rapidly rotating gas and dust, m...
Movies often portray black holes as giant cosmic vacuum cleaners, relentlessly sucking in other material until there’s nothing left. If that was how real black holes worked, there’d be no mystery as to where the supermassive kind came from: once an "ordinary" black hole had formed from stellar collapse, it would simply grow and grow until it reache...
