What happens to the strength of gravity when a black hole gain mass?

The strength of the gravitational field of the larger in mass black hole extends further then when it was smaller in mass. The size of the blackhole (i.e. its blackness) is not its actual size. It is the area where light simply cannot escape.

What happens to the gravitational field of a star that has collapsed into a black hole?

When a black hole is formed its(star) mass is not increased. according to the Newton’s laws of universal gravitation, gravitational field is proportional to its mass. so its gravitational field doesn’t increase.

How does the gravity of a black hole effect time and space around it?

However, according to Einstein’s theory, the object’s mass and gravity remain behind, in the form of an extreme distortion of the space and time around it. This distortion of space and time is the black hole. As you get closer to a black hole, the flow of time slows down, compared to flow of time far from the hole.

What is the main force that causes a star to turn into a black hole?

A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star’s life. Some black holes are a result of dying stars.

How does a black hole gain mass?

Black holes grow in mass by capturing nearby material. Anything that enters the event horizon cannot escape the black hole’s gravity. So objects that do not keep a safe distance get swallowed. Despite their reputation, black holes will not actually suck in objects from large distances.

Why do black holes have such a strong force of gravity?

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space.

How does gravity cause star formation?

As gravity compresses the core of a protostar, the temperature goes higher and higher. Eventually the temperature is high enough that the star starts fusing hydrogen into helium. When the outward pressure produced by the heating of the gas by fusion energy balances gravity, a stable star is formed.

What keeps a star from collapsing from its own gravity?

Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The outflow of energy from the central regions of the star provides the pressure necessary to keep the star from collapsing under its own weight, and the energy by which it shines.

What determines if a star turns into a black hole or neutron star?

If it is less than three solar masses it remains as a neutron star but if the star’s weight is more than about three solar masses, then it collapses further to form a black hole.

What happens to a star before it turns into a black hole?

When a star burns through the last of its fuel, the object may collapse, or fall into itself. For smaller stars (those up to about three times the sun’s mass), the new core will become a neutron star or a white dwarf. But when a larger star collapses, it continues to compress and creates a stellar black hole.

How does mass affect the gravitational pull of a star?

The gravitational pull is a function of its mass. If its mass goes down via some kind of supernova explosion then its gravitational pull will decrease. Then if it sucks mass back in, its gravitational pull will increase. The star’s overall gravity does not increase, the star just gets denser.

Why does the temperature of a star increase when it shrinks?

The temperature is higher than before because the star shrinks and the inward pressure due to gravity increases (because the star is now denser), requiring the core to be at a higher temperature to exert enough force to counteract this higher pressure.

What happens to the neutrons when a star’s core collapses?

However, if the original star was very massive (say 15 or more times the mass of our Sun), even the neutrons will not be able to survive the core collapse and a black hole will form! IV. More about the Stellar Endpoints

What happens when energy is released from a star?

This energy from fusion pours out from the core, setting up an outward pressure in the gas around it that balances the inward pull of gravity. When the released energy reaches the outer layers of the ball of gas and dust, it moves off into space in the form of electromagnetic radiation. The ball, now a star, begins to shine.
