The mass of a black hole determines its "size" or diameter of the event horizon. The relationship between mass and radius (Schwarzchild radius) is described by a formula in which the size is proportional to the gravitational constant and mass of the black hole and inversely proportional to the square of the speed of light.

Do medium size stars become black holes true or false?
False. Only the most massive stars will become black holes.
What would happen if two black hole were to merge into each other?
You would have a black hole the size of the combined mass of the two black holes.
Is black holes bigger than galaxies?
A black hole has a much larger mass than a planet. The mass of a black hole, however, is contained in a point that is smaller than some fundamental particles. The event horizon of a typical stellar mass black hole is much smaller than any planet, but the event horizons of supermassive black holes are much larger.
Is the black hole big?
Well if your comparing the smallest black hole knowen to humans to the Earth YES THEY ARE BIG but there is no definant diameter or size considering that all black holes are unique in all three size diameter and gravataional pull.
Can a black hole be as big as a human?
Technically yes, realistically, probably not. The best measure of the size of a black hole is the size of the event horizon. That we know of, black holes fall into two general categories: stellar mass black holes and supermassive black holes. The diameter of the event horizon is directly proportional to the mass. Stellar mass black holes range in mass from about 3 to 30 times the mass of the sun, with diameters several miles to several tens of miles. Supermassive black holes are millions to billions times the mass of the sun and are millions to billions of miles across. A black hole with roughly the mass of Saturn would have an event horizon about as wide as an adult human is tall, but there is no known way for an object of that mass to become a black hole.
How does the size of the central black hole relate to the size of a galaxy?
Roughly speaking, the larger galaxies tend to have larger central black holes.
Do mini black holes exist?
yes. some black holes are predicted to be the size of an electron.
How fast can black holes go?
there is no exact answer, different black holes have different speeds, but all black holes can crush 1 tonne of metal into a size of a pebble
Are black holes the size of stars?
Except for supemassive black holes, no. Most black holes have about the same mass as a star, but the event horizon is only a few miles across.
How are black holes measured in size?
By the diameter of their event horizon.
Do medium size stars become black holes true or false?
False. Only the most massive stars will become black holes.
Do medium size stars become black holes?
No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.
Can black holes grow and how?
Black holes can increase in mass (and therefore size; the diameter of a black hole's event horizon is directly proportional to its mass) by accretion, or taking in additional matter and/or energy.
Are there black holes the size of stars?
The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
Is there such thing as big black holes?
While scientists have never actually SEEN a black hole (they are called "black holes" because their gravity is so great that not even light can escape!) we believe that super-massive black holes are at the hearts of most galaxies. These super-massive black holes might be the mass of a million stars the size of the Sun, or larger.
Could black holes ever be technologicall created?
if you crush something the size of planet earth into something the size of a dime, it is tecnically "possible" to create a black hole.
Why all dead big stars do not form black holes?
All dead big stars do not form black holes because sometimes the collapse of the star is stopped at a smaller size before it becomes a black hole.
