What is a black hole

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. Black hole definition is - a celestial object that has a gravitational field so strong that light cannot escape it and that is believed to be created especially in the collapse of a very massive star. Black holes are the strangest objects in the universe a black hole does not have a surface, like a planet or star instead, it is a region of space where matter has collapsed in on itself this catastrophic collapse results in a huge amount of mass being concentrated in an incredibly small area.

And what enables a black hole to capture light simply, gravity gravity is a force associated with massive objects the more massive something is, the harder it tugs on objects around it. A black hole is a region of space from which nothing, including light, can escape according to the general theory of relativity, it is the result of the curving of spacetime caused by being composed of dense mass. An enormous black hole one hundred thousand times more massive than the sun has been found hiding in a toxic gas cloud wafting around near the heart of the milky way. Black holes may answer questions about the beginning and the future of the universe black holes may answer questions about the beginning and the future of the universe.

Black holes are points in space that are so dense they create deep gravity sinks beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. Black holes were first proposed to exist in the 18th century, but remained a mathematical curiosity until the first candidate black hole was found in 1964 it was called cygnus x-1, an x-ray source in the constellation cygnus. Since the energy from the black hole was the source of the newly created particles' mass (via e = mc 2), the black hole's mass shrinks slightly with every escaped particle unfortunately, the event horizon temperature is low for black holes like the ones we see, so hawking radiation is correspondingly much fainter than other sources of light.

Calculations suggest that what the fabric of spacetime looks like inside a black hole depends on that particular black hole's history it might be turbulent, twisted, or any other number of things. The basic building block of the black hole is that singularity: a pinpoint region of space that contains all the mass of the black holearound it is a region of space from where light cannot escape, giving the black hole its name.

Black holes are places of mystery the laws of physics predict their existence but cannot explain what happens inside a black hole once we can do that, we will have stepped beyond the work of. 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.

Schematic of a black hole in a binary system, showing the accretion disk around the black hole and emission of x-rays photo courtesy cxc/slee the star cygnus x-1 is a strong x-ray source and is considered to be a good candidate for a black hole. How does a black hole form we think that a black hole can form when a very massive star collapses at the end of its lifetime stars become like our sun because of energy from nuclear reactions going on deep inside the star. A black hole, in the context of computer networks, is a place where incoming packets are destroyed or discarded without informing the sender or recipient of their failed delivery.

  • A black hole is an area of such immense gravity that nothing—not even light—can escape from it black holes form at the end of some stars' lives the energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.
  • Black hole definition, a theoretical massive object, formed at the beginning of the universe or by the gravitational collapse of a star exploding as a supernova, whose gravitational field is so intense that no electromagnetic radiation can escape.
  • A supermassive black hole (smbh or sbh) is the largest type of black hole, on the order of hundreds of thousands to billions of solar masses (m ☉), and is found in the centre of almost all currently known massive galaxies.

Black hole n 1 a massive star in the last phase of its evolution, in which the star collapses, creating a volume of spacetime with a gravitational field so intense that its. A black hole is a location in space that possesses so much gravity, nothing can escape its pull, even light learn more about what black holes are and the latest news. According to nasa, the black hole is 10 times more massive to the sun nearby is a blue supergiant star that is about 20 times more massive than the sun, which is bleeding due to the black hole.
