It is generally believed that the mass of a black hole can indeed decrease, through the mechanism of Hawking radiation. A simplified view of this is that quantum fluctuations near the event horizon, influenced by gravity, can generate particle pairs, one of which can escape the vicinity of the black hole and thus carry away energy or mass. In effect this is a thermodynamic interaction with the universe as of black body radiation; the apparent temperature of the black hole being inversely proportional to the its mass. By this mechanism a black hole could 'evaporate', with the rate of evaporation increasing as the mass decreases.
This does of course presume that the amount of radiation emitted (Hawking radiation is calculated to be quite weak) is not balanced by the rate at which matter or energy is being absorbed by the black hole.
What else can I help you with?
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.
If instead of the sun there was a black hole of the same mass in the center of the solar system would all the planets have the same orbits?
No. The sun is decreasing in mass (fusion) over time whereas a black hole would increase in mass over time (sucking up astroids, gas, etc). So over very long periods of time the sun's gravitational force will significantly decrease, and if it was a black hole it would increase. Increase/decrease in mass directly affects increase/decrease in gravitational force. Since gravitation (and motion) is what causes orbit, over long periods of times the planets would have very different orbits in the two scenarios (sun vs black hole).
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.
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.
When a black hole collaspes does its mass decrease?
As far as we know, black holes cannot collapse any further. However, if a star were to collapse and form a black hole, its mass would be the same.
Has a black hole ever been in hour galaxy?
I assume you mean "our galaxy". There is a supermassive black hole, with a mass that is about 4 million times the mass of our Sun, at the center of our galaxy.
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.
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.
How will the gravitation field decrease?
By losing mass (i.e. energy). For example, a black hole can lose some of its mass by means of so-called Hawking radiation.
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.

Do Black holes suck in all Matter?

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.
What did society think about black holes before Stephen Hawking?
Stephen Hawking applied Quantum Mechanics to the mathematics of black holes, before this they had only been studied using General Relativity. With only General Relativity black holes could only form from the collapse of large stars, there was a minimum mass for a black hole, things only fell into a black hole causing its mass to always increase never decrease. With Quantum Mechanics added black holes could form early in the Big Bang before any stars existed, there was no minimum mass for a black hole, a black hole could emit particle radiation thus losing mass and the more mass it lost the faster it lost mass resulting in the black hole exploding in a flash of particle radiation and ceasing to exist.
