Black hole?presumed a very massive object=What is its average mass?

Question

Our milky way has about 10^42 kg mass=a black hole must be millions of times more massive?

Can a massive black hole be the size of an electron?Than it could suck in light ?

Doesnt black holes grow in size as they suck in light?

Answer 1

The black hole is even smaller than a white dwarf, it has a much more gravitational force, so the black hole is very powerful but very small. it can even bend light due to it's gravitational force. if I remember correctly my science teacher said last year that it is about the size of an average fist.

Answer 2

Well it depends on which type of black hole you are referring to.

1. If you are referring to stellar black holes which are black holes formed by the gravitational collapse of a massive star, then it should have the mass of a typical massive star ( 3 or more sollar masses). The least it can have is 1.44 solar mass which is also called "Chandrasekhar limit".

2. If you are referring to a supermassive black hole which is a black hole with a mass in the range of a few times 10^5 to a few times 10^10 of solar masses. It is currently thought that most, if not all galaxies, including the Milky Way, contain a supermassive black hole at their galactic center.

Remember though, that a black hole could exist of any mass in theory according to general relativity. The lower the mass, the higher the density of matter has to be in order to form a black hole. So far the process of the formation of a black holes with mass less than a few times of that of the Sun is not currently known but it could be possible that primordial black holes exist. These black holes are not formed by the usual gravitational collapse. They are hypothetically thought of forming by the extreme density of matter present during the universe's early expansion.

Answer 3

it is the stereotypes in our race based the place you reside. initially all of us had black hair. by the years a mutation got here which made blue eyes and blonde hair. Then the gene traits are exceeded to babies. human beings have distinctive dermis coloration based on the section they stay international.
