The demand for consistency between a quantum description of matter and a geometric description of spacetime,  as well as the appearance relativiteitstheorei singularities where curvature length scales become microscopicindicate the need for a full theory of quantum gravity: Because neutron stars are immensely compact, significant amounts of energy are emitted in the form of gravitational radiation.
While general relativity replaces the scalar gravitational potential of classical physics by a symmetric rank -two tensorthe latter reduces to the former in certain limiting cases. Theory and Practice of Natural Computing: According to general relativity, a binary system will emit gravitational algemmene, thereby losing energy.
It is used to detect the presence and distribution of dark matterprovide a “natural telescope” for observing distant galaxies, and to obtain an independent estimate of the Hubble constant.
There are algmeene types of horizons. This and related predictions follow from the fact that light follows what is called a light-like or null geodesic—a generalization of the straight lines along which light travels in classical physics.
Instead there are approximate inertial frames moving alongside freely falling particles. Examples of such differences include gravitational time dilationgravitational lensingthe gravitational redshift of light, and the gravitational time delay.
The bending of light by gravity can lead to the phenomenon of gravitational lensing, in which multiple images of the same distant astronomical object are visible in the sky. Translated into the language of spacetime: Brans—Dicke theory Kaluza—Klein Quantum gravity. This is not the case for a close binary pulsar, a system of two orbiting neutron starsone of which is a pulsar: Hulpmiddelen Links naar deze pagina Verwante wijzigingen Bestand uploaden Speciale pagina’s Permanente koppeling Paginagegevens Wikidata-item Deze pagina citeren.
In the currently accepted models of stellar evolutionneutron stars of around 1.
The resulting Newton—Cartan theory is a geometric formulation of Newtonian gravity using only covariant concepts, i. The effect can also be derived by using either the exact Schwarzschild metric describing spacetime around a spherical mass  or the much more general post-Newtonian formalism.
One attempt to overcome these limitations is string theorya quantum theory not of point particlesbut of minute one-dimensional extended objects. The main reason is that the gravitational relativitwitstheorie any physical field—must be ascribed a certain energy, but that it proves to be fundamentally impossible to localize that energy.
Here, too, scientists have argued that the evidence indicates not a new form of energy, but the need for modifications in our cosmological models, cf.

Schutzsec. Instead, gravity corresponds to changes in the properties of space and time, which in turn changes the straightest-possible paths that objects will naturally follow. For numerical results, see the review Bergersec. Attempts to generalize ordinary quantum field theories, used in elementary particle physics to describe fundamental interactions, so as to include gravity have led to serious problems.
Special relativity is defined in the absence of gravity, so for practical applications, it is a suitable model whenever gravity can be neglected.
It was clearly superior to Newtonian gravitybeing consistent with special relativity and accounting for several effects unexplained by the Newtonian theory. Time dilation Mass—energy equivalence Length contraction Relativity of simultaneity Relativistic Doppler effect Thomas precession Ladder paradox Twin paradox. Within the Solar System or for ordinary double starsthe effect is too small to be observable.
Views Read Edit Re,ativiteitstheorie history. Einstein derived these effects using the equivalence principle as early ascf. Also, relativistic lensing effects are thought to play a role for the signals received from X-ray pulsarscf.
A more exact mathematical description distinguishes several kinds of horizon, notably event horizons and apparent horizons cf.

As thermodynamical objects with non-zero temperature, black holes should emit thermal radiation.
These theories rely on general relativity to describe a curved background spacetime, and define a generalized quantum field theory to describe the behavior of quantum matter within that spacetime.

Meer precies is de einstein-tensor een object dat uitgedrukt kan worden in termen van tweede afgeleides van de metriek van een gegeven ruimte.
Paraphrasing the relativist John Archibald Wheelerspacetime tells matter how to move; matter tells spacetime how to curve.
