What is a collapsed star from which light cannot escape?

A black hole.


What is the sphere around a collapsed star from which light can not merge called?

It seems you are referring not to any collapsed star, but a black hole. The "event horizon" is the area from which nothing can escape.


A collapsed star from which light cannot escape?

A black hole is a collapsed star with such a strong gravitational pull that not even light can escape from it. This phenomenon occurs when a massive star runs out of nuclear fuel and collapses under its own gravity. The boundary surrounding a black hole, beyond which nothing can escape, is called the event horizon.


What is a star in which light cannot escape because of the immense gravitational pull at its surface called?

A star in which light cannot escape because of its immense gravitational pull at its surface is called a black hole.


What kind of star is invisible?

An invisible star could refer to a theoretical black hole, which cannot be directly observed because light cannot escape from it. Alternatively, a brown dwarf, a failed star that emits very little light and is difficult to detect, could be described as invisible.


What is the sphere around a collapsed star from which light can not emerge called?

That refers specifically to black holes (there are other types of "collapsed stars"). This sphere is called the "event horizon".


A star that has collapsed under gravity?

A collapsed star is typically referred to as a black hole. Black holes form when massive stars run out of fuel and collapse under gravity, creating a region of spacetime with such intense gravitational pull that nothing, not even light, can escape from it.


How is a neutron star different from a black hole?

A neutron star is the collapsed core of a star in which atoms have been crushed, and electrons have fused with protons to form neutrons. The collapse stops at this point. A neutron star is extremely dense but has a finite density and emits radiation. A black hole is an object that has collapsed completely to an infinitely dense point. It cannot really be considered matter at this point. Around this singularity is a region of extremely strong gravity and highly distorted spacetime from which nothing, not even light can escape.


What is a massive collapsed star?

A massive collapsed star is a dead star.


Do black holes have cooling outer layers?

A black hole is a collapsed star that is very small and a gravitational pull that is so strong that light cannot escape from it. No, they do not have outer colling layers. They just pull in anything that gets near it and crushes it to atoms. We can tell they exist by the effect they have on nearby objects.


A collapsed star whose gravity is 100000 times stronger than earth's?

This would likely be a black hole, where the intense gravity comes from a mass that has collapsed to a very small size. The gravitational force near a black hole is so strong that not even light can escape, making them invisible. Their extreme gravity can warp spacetime and have significant effects on surrounding matter and light.


what is a collapsed star ?

A collapsed star is a term used to describe a "dead" star, which is a star that has come to the end of its lifetime and just collapses on itself. A black hole
