Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun.

The Milky Way hosts an SMBH with mass a few million times the solar mass.

Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young.

For example, a billion solar mass black holes are found when the universe was just 6% of its current age, 13.7 billion years.

Dark matter halo is the halo of invisible matter surrounding a galaxy or a cluster of galaxies.

Although dark matter has never been detected in laboratories, physicists remain confident this mysterious matter that makes up 85% of the universe's matter exists.

Were the visible matter of a galaxy not embedded in a dark matter halo, this matter would fly apart.

In our currently favored models of the evolution of the Universe, most of the matter in the Universe is not like the stuff that you, I, this computer or the stars are made out of.

Instead, it is a substance called dark matter, so-called because it emits no light and can only interact via gravity.

In this model, when the Universe was very young, the dark matter was relatively smoothly distributed throughout the Universe.

But this situation couldnt last, because of gravity.

Areas of the Universe which had just very slightly more dark matter than other areas exerted stronger gravity, pulling more dark matter towards them and causing them to get bigger, so they exerted even more gravity... this runaway effect caused all of the dark matter to start clumping together, forming what astronomers call "halos" of dark matter.
