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 big do event horizons get?

Assuming you mean the event horizon of a black hole (there are other types as well), the diameter of a black hole as measured by its event horizon is directly proportional to its mass. The larger the mass, the larger the diameter. Thus, as a black hole's mass increases, it will get bigger. The only limitation is how much mass a black hole is able to incorporate from its surroundings.


How many properties of the matter inside a black hole can be measured from outside the black hole?

Only three properties can be measured from outside a black hole: mass, electric charge, and angular momentum (spin). These properties determine the black hole's gravitational effects on its surroundings and are observable through the gravitational pull they exert on nearby objects or through the radiation emitted by the black hole.


How can scientists determine the mass of a black hole?

Scientists can determine the mass of a black hole through various methods, including observing the orbits of objects around the black hole, analyzing the gravitational lensing effects of the black hole on light, and studying the X-ray emissions from material falling into the black hole. These observations help scientists calculate the mass of the black hole based on the influence it has on its surroundings.


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.

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 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.

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.


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.

Is there any way to calculate the mass of a black hole?

Currently, the way the mass of a black hole is measured is indirectly determined by the speed of its rotation and/or its gravitational influence. Note: Theoretically, the faster a black hole rotates, the more massive it is. The gravitational influence is estimated by the diameter of the event horizon (or even as the difference between the spherical edge of the event horizon and the edge of the oblate diameter of its ergosphere). Also the latest consensus is that there is not a relevant relationship between the observable size of the accumulated bulge about the Black Hole and the size of the Black Hole itself.


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.
