- Current theory suggests that, as an object falls into a black hole and approaches the singularity at the centre, it will become stretched out or spaghettified due to the increasing differential in gravitational attraction on different parts of it, before presumably losing dimensionality completely and disappearing irrevocably into the singularity ...

History of general relativity General relativity (GR) is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses.

gravitational acceleration Gravitational acceleration (symbolized g) is an expression used in physics to indicate the intensity of a gravitational field. It is expressed in meters per second squared (m/s 2 ). At the surface of the earth, 1 g is about 9.8 m/s 2 . The use of the term acceleration in conjunction with gravity arises from Einstein's principle of equivalence, which was a cornerstone in the development of the general theory of relativity.

Gravitational constant The gravitational constant is a physical constant that is difficult to measure with high accuracy. In SI units, the 2014 CODATA-recommended value of the gravitational constant (with standard uncertainty in parentheses) is: with relative standard uncertainty 6995470000000000000♠4.7×10−5.

Graviton Technology Graviton Research Edit. Requirements: Research Lab Level 12 Is Required For: Death Star; Strategy and description Edit. A graviton is an elementary particle that is massless and has no cargo. It determines the gravitational power. by firing a cocentrated load of gravitons, an artificial gravitational field can be constructed. not unlike a black hole, it draws mass into itself. thus it can destroy ships and even entire moons. to produce a sufficient amount of gravitons, huge amounts of energy are required.

- The Gravitational Field. A field is something that has a magnitude and a direction at every point in space. Gravity is a good example-we know there is an acceleration due to gravity of about 9.8 m/s 2 down at every point in the room.Another way of saying this is that the magnitude of the Earth's gravitational field is 9.8 m/s 2 down at all points in this room. Gravitational field: g = F /m. where F is the force of gravity.We can draw a field-line pattern to reflect that, near the Earth's surface, the field is uniform.nother way of saying this is that the magnitude of the Earth's gravitational field is 9.8 m/s 2 down at all points in this room.

- Quantum gravity is an overall term for theories that attempt to unify gravity with the other fundamental forces of physics (which are already unified together). 1  It generally posits a theoretical entity, a graviton, which is a virtual particle that mediates the gravitational force.

Difference Between Gravity and Gravitational Force Gravity and gravitational force are two concepts that occur when objects with masses are placed in a finite distance from one another. Gravitational force along with electromagnetic force, weak nuclear force, and strong nuclear force build the four fundamental forces of the universe.

Technological singularity Martin Ford in The Lights in the Tunnel: Automation, Accelerating Technology and the Economy of the Future postulates a technology paradox in that before the singularity could occur most routine jobs in the economy would be automated, since this would require a level of technology inferior to that of the singularity.

Gravitational singularity A gravitational singularity (sometimes called a spacetime singularity) is a term used to describe the center of a black hole where gravity is thought to approach infinity. In the center of each black hole is a singularity, a point where infinite density develops as spacetime approaches it. Spacetime goes toward infinite curvature and matter is crushed to infinite density under the pull of infinite gravity.

gravity wave (or gravitational wave) Part of the Computing fundamentals glossary: A gravity wave (or gravitational wave) is a ripple in the curvature of the space-time continuum (the enmeshed combination of our three perceived physical dimensions, plus time) created by the movement of matter.f a gravitational wave were to pass through, the distance between the weights (which is measured by a laser beam moving back and forth between the mirrors and then recombined at a photodetector) would be altered.

Gravitational Waves Discovered from Colliding Black Holes The Laser Interferometer Gravitational-Wave Observatory (LIGO) has discovered ripples in space-time created by merging black holes. About 1.3 billion years ago two black holes swirled closer and closer together until they crashed in a furious bang.

- Yes, at infinity separation, the gravitational attraction between two objects is zero. You typically measure the force of gravity between two objects by measuring the distance between their center of masses, and then treating them like they're point particles with mass at that point. For two obejcts, the force of gravity between them is: f = G* m1* m2/r2. Where G is Newton's constant, m1 and m2 are the masses and r is the distance between their center of masses. So if you put a point between two objects where the force from one is equal to the force from another they would cancel.

General relativity General relativity is a metric theory of gravitation. At its core are Einstein's equations, which describe the relation between the geometry of a four-dimensional, pseudo-Riemannian manifold representing spacetime, and the energy–momentum contained in that spacetime.

Theory of relativity Technically, general relativity is a theory of gravitation whose defining feature is its use of the Einstein field equations. The solutions of the field equations are metric tensors which define the topology of the spacetime and how objects move inertially.

- Since the forces of matter can not overcome the force of gravity, all the mass of a black hole compresses to infinity at the very center, called the singularity. A black hole can come in any size. Stellar mass black holes are thought to form from supernova events, and have radii of 5 km.

Gravitational singularity Singularities can also be divided according to whether or not they are covered by an event horizon (naked singularities are not covered). According to modern general relativity, the initial state of the universe, at the beginning of the Big Bang, was a singularity.
