Black holes

Did you expect to see invisible light? Note the gravitational lensing effect, which produces two enlarged but highly distorted views of the Cloud. Instead, scientists must rely on the radiation that is emitted as dust and gas are drawn into the dense creatures.

Neutron Star Collapse Neutron stars are a special type of star with an extremely dense core. He said that they would be given off by the collision of very massive objects.

The event horizon of a black hole is the boundary around the mouth of the black hole where light loses its ability to escape. As the surface of the star nears an imaginary surface called the "event horizon," time on the star slows relative to the time Black holes by observers far away.

A similar process can occur if a normal star passes close to a black hole.

They just pull things close and then suck them in. Gravity is a force associated with massive objects. A video about black holes.

Black Holes

The first object considered to be a black hole is Cygnus X Thirdly, the mass would produce so much curvature of the space-time metric that space would close up around the star, leaving us outside i.

Under the classical mechanics of physics, nothing can escape from a black hole. This behavior is so puzzling that it has been called the black hole information loss paradox.

And what enables a black hole to capture light? Why are Black Holes Black? The behavior of the horizon in this situation is a dissipative system that is closely analogous to that of a conductive stretchy membrane with friction and electrical resistance —the membrane paradigm.

As a result, it appears as a big black dot. Black holes consume the dust and gas from the galaxy around them, growing in size. The degree to which the conjecture is true for real black holes under the laws of modern physics, is currently an unsolved problem. Because a black hole eventually achieves a stable state with only three parameters, there is no way to avoid losing information about the initial conditions: A complete extension had already been found by Martin Kruskalwho was urged to publish it.

Black holes are strange regions where gravity is strong enough to bend light, warp space and distort time.Aug 28,  · Click here to read a transcript of this story. Space is a pretty dark place. Even so, some areas are darker than others.

Nothing is darker than a black hole. A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes.

Black holes are regions of space that have such strong gravity, nothing can escape. They pull things close and suck them in.

Black Holes: Facts, Theory & Definition

What happens after, no one knows. Black holes may answer questions about the beginning and the future of the universe. Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.

The result is a gravitational field so strong that nothing, not even light, can escape.

Black holes may solve some of the mysteries of the universe. A black hole is a place in space where gravity pulls so much that even light cannot get out. A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.

The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon.
