How big are black holes and what factors determine their size?
Black holes can vary in size, with some being as small as a single atom and others being millions of times larger than our sun. The size of a black hole is determined by the amount of mass it has, with more massive black holes being larger. Additionally, factors such as the rate at which the black hole is consuming matter and its age can also influence its size.
How can gravity or anything be infinite?
The classical idea about black holes is that in a black hole, mass is concentrated to an infinitely small size, so it has an infinite density. That would cause an infinite gravitational field. However, this infinite density, etc. seems doubtful in view of quantum physics - but what exactly happens near the center of a black hole has not been completely clarified yet.
What is the size of a black hole and how does it compare to other celestial objects in the universe?
A black hole is a region in space where gravity is so strong that nothing, not even light, can escape from it. The size of a black hole is determined by its mass, with smaller black holes being about the size of a city and larger ones being millions of times bigger than our sun. Compared to other celestial objects in the universe, black holes can be much smaller or much larger, depending on their mass.
What is the size of a black hole and how does it affect its gravitational pull?
The size of a black hole is determined by its mass, with smaller black holes having a smaller size. The gravitational pull of a black hole is incredibly strong due to its mass being concentrated in a very small space, creating a powerful gravitational force that can even trap light.
Do all galaxies have black holes?
Not all galaxies have black holes. While many galaxies, including our own Milky Way, have supermassive black holes at their centers, there are also galaxies that do not have black holes. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.
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.
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.
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 an Intermediate-mass black hole a type of black hole?
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
Could super force be what causes black hole to be the size of an atom with seemingly infinite mass?
No. You are confusing several different parts of physics together, and it is a garbled mess.Black holes do not have "seemingly infinite mass". They have about the same mass as any other star - less because of their formation via supernovae - and act accordingly.Black holes are not the size of atoms. One part is crushed into a singularity by its own mass, creating a single point in space (a point, with zero volume) that has technically infinite density.This is done by gravity. Gravity is by far the weakest of the four basic forces. It is not a superforce, but the cumulative effect of this force.
How do black holes and vacuums relate by size?
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.
How big are black holes and what factors determine their size?
Black holes can vary in size, with some being as small as a single atom and others being millions of times larger than our sun. The size of a black hole is determined by the amount of mass it has, with more massive black holes being larger. Additionally, factors such as the rate at which the black hole is consuming matter and its age can also influence its size.
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.
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.
How can gravity or anything be infinite?
The classical idea about black holes is that in a black hole, mass is concentrated to an infinitely small size, so it has an infinite density. That would cause an infinite gravitational field. However, this infinite density, etc. seems doubtful in view of quantum physics - but what exactly happens near the center of a black hole has not been completely clarified yet.
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.
