By the gravitational collapse of massive stars - once they stop producing energy.
Black Holes.
No, black holes are not created daily. Black holes are formed from the remnants of massive stars that have undergone supernova explosions or from the collisions of other black holes. The rate at which new black holes are formed in the universe is relatively low.
Answer
The density of matter just after the big bang is calculated to be sufficient to have spontaneously created black holes; such are called primordial black holes, and searches for their existence are ongoing.
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
There are already black holes within the universe
Black Holes' can 'eat' any type of matter in the Universe.
Probably stellar mass black holes
The universe likely contains millions upon millions of black holes.
No.
Yes.
Black holes are found throughout the universe, typically at the centers of galaxies. They are created when massive stars collapse under their own gravity. Black holes have immense gravitational pull and can distort spacetime around them, making them fascinating objects for study in astrophysics.
