Most black holes are believed to form when very massive stars die.
no because black holes can only form through supernovas.
Mostly the center of the galaxy.
Most or all galaxies appear to have supermassive black holes at their centers and probably have stellar mass black holes scattered throughout.
Yes. Some galaxies, particularly irregular galaxies, appear to lack supermassive black holes.
Astronomers
yes, there are the nebulae, black holes, and planets, but mostly the space in between the stars is nothingness
Mostly in galaxies, where they can form Super Massive Black Holes.
Black Holes are mostly located at Star's that have Died or Exploded from running out of heat or in which cases The Sun that hasent ran out of energy yet or other stars, you get what i'm saying
Black holes affect humans in 2 ways: 1. By stretching them to the width of one atom (spaghettification) 2. By converting them into energy (mostly in the form of X-rays)
No. They appear to be real objects, and have been observed in various ways. Stars near the centers of galaxies as seen to move in ways that are possible only if they are rapidly orbiting black holes.
Mostly by theory and computer simulation. All observations are necessarily indirect.
