An old star collapsing in on itself, to put it in simple terms.
Black holes are not made up of dark matter. Dark matter is a mysterious substance that makes up a large portion of the universe's mass, but black holes are formed from the collapse of massive stars.
in dark holes
There are no black holes but there are dark areas known as Sun spots.
Dark matter, dark energy, nebulae, stars, black holes, planets, comets, asteroids, meteors, satellites, supernovas etc. make up an elliptical galaxy.
No, dark matter is quite a different kind of thing. A dark hole may have absorbed some dark matter, but pressumably that would become indistinguishable from the normal matter, once it gets crushed by the enormous gravity of the black hole.
Dark matter is a mysterious substance that makes up a large portion of the universe's mass, but its exact nature is still unknown. While some theories suggest that dark matter could potentially be made up of black holes, this idea is not widely accepted among scientists. More research and evidence are needed to determine the true nature of dark matter.
The Dark Side
Thankfully there are none.
No. And the term is "black hole," not "dark hole."
Stars, dust, gas, black holes, dark matter...By far the most significant component, in terms of mass, is dark matter, making up about 80-90% of a galaxy's mass.
Dark matter and black holes are both mysterious components of the universe, but they are not directly related. Dark matter is an invisible substance that makes up a large portion of the universe's mass, while black holes are extremely dense regions in space where gravity is so strong that not even light can escape. While dark matter may influence the formation and behavior of black holes, they are fundamentally different phenomena in the cosmos.
