What else can I help you with?
How far from a black hole's event horizon would you have to be to experience the equivalent of Earth's gravity?
That would depend on the mass of the black hole. Here are some values: 3 solar masses: 3.96 million miles 30 solar masses: 12.5 million miles 1000 solar masses: 72.3 million miles 1 million solar masses: 2.23 billion miles 4 million solar masses: 4.57 billion miles 100 million solar masses: 22.7 billion miles 1 billion solar masses: Within the event horizon
What is a stelar black hole?
That refers to a black hole that results from the gravitational collapse of a star, and which has a mass between 3 solar masses and several solar masses, depending on the mass of the star that collapsed.
What is a supermassave black hole?
A supermassive black hole refers to a black hole of considerable mass - usually between around a million solar masses, and several billion solar masses. Such huge black holes are found in the center of all large galaxies.
What forms from a supernova?
Depending on the mass of the original star it will either end up as a neutron star (< 20 solar masses) or a black hole (> 20 solar masses).
What is the mass range for a supermassive black hole?
Anywhere from about 100,000 solar masses (100,000 times the mass of our Sun), to more than 10 billion solar masses (the approximate size of the largest known black holes).
Are black holes bigger than the whole solar system?
If you mean the event horizon, it is very possible but none have been discovered. The largest black hole's (At 40 billion solar masses (1 = Sun mass)) event horizon is about 789 au which if it were the Sun, would reach beyond the mean distance from the Sun to Sedna. For reference, the solar system is about 1,921.56au if you measure to the heliopause. The size required to be large than the solar system would be, if my math is correct, over about 97.3 billion solar masses.
What is the weight of a supermassive black hole?
For a black hole to fall into the supermassive category, it usually would need to have the equivalent of hundreds of thousands up to millions of solar masses. The supermassive black hole at the nucleus of our Milky Way galaxy is calculated to be over 4 million solar masses. The heaviest known black hole, which is still the subject of study, may be as heavy as 40 billion solar masses. (The Sun weighs about 2 x 10^30 kg).
How may sun's will it take to make 1 black hole?
A black hole needs to be a minimum of about 3 or 4 solar masses.
What would be the Schwarzschild radii of black holes of 1 billion solar masses?
The Schwarzschild radius is directly proportional to the mass of the black hole. It is about 2.95 km for every solar mass.
What is the difference between stars that become white dwarfs stars that become neutron stars and stars that become black holes?
The difference is in mass. Low to medium mass stars (up to about 8-10 solar masses) become white dwarfs. Massive stars (10 to 25 solar masses) become neutron stars. Stars above 25 solar masses tend to become black holes.
How large can the volume of a black hole get?
There is no theoretical limit to the MASS of a black hole. The largest known black holes have a mass in excess of a billion solar masses... so far. In the distant future, you can expect them to continue growing.The DIAMETER or the RADIUS of a black hole is directly proportional to the black hole's mass; the radius would be about 3.0 kilometers for every solar mass. The diameter, of course, is twice as much. Thus, a black hole of 10 billion solar masses would have a radius of 30 billion kilometers... about 200 AU.
What determines whether a star eventually becomes a black dwarf or a neutron star?
The stars solar mass, or relative size to the sun. If its gravity is big enough, when it does condense in on itself, it will create a black hole. If not, it will form a highly dense clump of matter, or a Neutron Star If the stars mass is more than 3 solar masses, it will form a black hole. If it is less, it will form a neutron star
