By measuring it's gravity. The faster things are orbiting the black hole, the more gravity and the more mass it has.

What happens to a mass when it is swallowed by a black hole?

The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.


How do scientists calculate the mass of a black hole?

Scientists calculated indirectly the mass of a black hole by the behavior of matter around it, from which its gravitational pull can be determined, and with an accurate measure of its distance, its mass can then be inferred. In some cases an upper limit can be calculated by the closest approach of a visible object observed near it; in this case, its size is a result of a direct relation to its mass since the radius of the event horizon is directly proportional to the black hole's mass.


How can the mass of a black hole can be measured?

The mass of a black hole can be measured by observing the orbits of objects around it, such as stars or gas clouds. By studying the gravitational effects of the black hole on these objects, astronomers can calculate its mass. Another method is to measure the distortion of light from objects behind the black hole, known as gravitational lensing, which can provide information about the black hole's mass.


What happen if a quark star accidentally collide with a black hole?

If a quark star were to collide with a black hole, several outcomes are possible depending on the mass and velocity of the objects. Potential scenarios include the quark star being devoured by the black hole, leading to an increase in the black hole's mass, or a violent event such as the emission of gravitational waves and high-energy particles. These collisions are complex phenomena that are still being studied by scientists.


What happens if a black hole runs into another black hole?

They will merge to form a single black hole with the combined mass of the town that merged.

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.


How big is a black hole and what factors determine its size?

A black hole's size is determined by its mass, which is the amount of matter it contains. The more mass a black hole has, the larger its size. The size of a black hole is typically measured by its event horizon, which is the point of no return where gravity is so strong that not even light can escape. The event horizon's size is directly related to the mass of the black hole.

What is the relationship between the mass of a black hole and its density?

The relationship between the mass of a black hole and its density is that as the mass of a black hole increases, its density also increases. This means that a black hole with a higher mass will have a higher density compared to a black hole with a lower mass.

Is there a black hole in the milky way?

Scientists are now largely convinced that there is indeed one at the centre of the galaxy... the evidence indicates a compact high-mass object there; if it's not a black hole, we don't know what else it could be.


What becomes of energy when it is sucked up into a black hole?

Such energy has a mass equivalent (m = e/c2). Any such mass falling into the balck hole will increase the mass of the black hole.


What do scientists think is in center of the Milky Way?

The very center is believed to contain a very powerful black hole.


Does the hole in a black hole expand the older the black hole gets?

No. If no matter enters a black hole it will actually slowly lose mass and shrink via Hawking radiation. A black hole will gain mass if matter fals into, which will cause the event horizon to grow.


How is the formation of a normal black hole different from the formation of a supper-massive black hole?

It is not yet known for sure how a supermassive black hole acquires the enormous mass it has. It is possible that it starts as a normal black hole, and then gets more mass. It is also possible that from the start, a much larger amount of mass than in a normal black hole collapses.
