Black holes are very dense. - Kara delikler çok yoğundur.
The supermassive black hole at the centre of the galaxy remained a mystery for thousands of years... - Galaksinin merkezindeki çok büyük kara delik binlerce yıl bir gizem olarak kaldı.
A gravitationally domineering celestial body with an event horizon from which even light cannot escape; the most dense material in the universe, condensed into a singularity, usually formed by a collapsing massive star
caused by the death of an extremely large star, black holes have gravitational fields strong enough to trap light Black holes consist of a singularity, the center where all the mass resides, and an event horizon, a black disk encircling the singularity and the point at which light can no longer escape the gravitational forces of the black hole
a region of space resulting from the collapse of a star; extremely high gravitational field
Area in space where matter is so densely packed that the gravitational field produced permits nothing to leave, not even light [Image]
{i} theoretical space object which has an extremely strong gravitational force; dungeon
The configuration of a massive star that has undergone gravitational collapse, in which gravitation at the surface is so intense that even the star's own light cannot escape
A star which has collapsed on itself because of its extremely large gravitational force from which not even light can escape
A region of space surrounding a very massive collapsed star, or "collapsar" from which not even light can escape
An object with such high gravity that not even light can escape These may be formed when the most massive of stars die, and their cores collapse into a superdense mass
A region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull
Black holes are areas in space, where gravity is so strong that nothing, not even light, can escape from them. Black holes are thought to be formed by collapsed stars. Cosmic body with gravity (see gravitation) so intense that nothing, not even light, can escape. It is suspected to form in the death and collapse of a star that has retained at least three times the Sun's mass. Stars with less mass evolve into white dwarf stars or neutron stars. Details of a black hole's structure are calculated from Albert Einstein's general theory of relativity: a "singularity" of zero volume and infinite density pulls in all matter and energy that comes within an event horizon, defined by the Schwarzschild radius, around it. Black holes cannot be observed directly because they are small and emit no light. However, their enormous gravitational fields affect nearby matter, which is drawn in and emits X rays as it collides at high speed outside the event horizon. Some black holes may have nonstellar origins. Astronomers speculate that supermassive black holes at the centres of quasars and many galaxies are the source of energetic activity that is observed. Stephen W. Hawking theorized the creation of numerous tiny black holes, possibly no more massive than an asteroid, during the big bang. These primordial "mini black holes" lose mass over time and disappear as a result of Hawking radiation. Although black holes remain theoretical, the case for their existence is supported by many observations of phenomena that match their predicted effects
An object whose gravity is so strong that the escape velocity exceeds the speed of light
one possible end point of a star's life A black hole's gravity is so strong that not even light can escape it's surface
(a) Formed when a star of greater than about 10 solar masses reaches the end of its lifespan, having fused as much matter as possible The star collapses under its own gravity to a size determined by the Schwarzschild radius, at which point its gravity becomes so great that not even light can escape These objects are responsible for gravitational lensing effects and are also thought to be the explanation for some types of active galactic nuclei (b) Formed deliberately by goblins as a repository for all the socks you lose in the laundry
A region of spacetime, surrounding an extremely dense concentration of matter, in which the gravitational force is so strong that matter and energy cannot escape from it
a region in space where gravity is so strong that not even light can escape from it Black holes in our galaxy are thought to be formed when stars more than ten times as massive as our Sun end their lives in a supernova explosion There is also evidence indicating that supermassive black holes (more massive than ten billion Suns) exist in the centers of some galaxies
If the mass of a dying star is greater than about 2 to 3 solar masses then it cannot form a neutron star This is because the neutron degeneracy pressure will no longer support the star at this mass The star then completely collapses to a singularity The mass is concentrated into an infinitesimally small volume and this distorts the space-time continuum to such an extent that nothing can escape from the black hole Click here for more
a body whose escape velocity is greater than the speed of light, causing gravity to pull back toward the body any light it would otherwise emit (see black holes)
A region of space around a very small and extremely massive collapsed star within which the gravitational field is so intense that not even light can escape
