Gravitational time dilation Wikipedia. Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events as measured by observers situated at varying distances from a gravitating mass. The higher the gravitational potential the farther the clock is from the source of gravitation, the faster time passes. Albert Einstein originally predicted this effect in his theory of relativity and it has since been confirmed by tests of general relativity. This has been demonstrated by noting that atomic clocks at differing altitudes and thus different gravitational potential will eventually show different times. Definicion De Cuenta Corriente A La Vista. The effects detected in such Earth bound experiments are extremely small, with differences being measured in nanoseconds. Relative to the earths age in billion of years, the earths core is effectively 2. Demonstrating larger effects would require greater distances from the Earth or a larger gravitational source. Gravitational time dilation was first described by Albert Einstein in 1. In general relativity, it is considered to be a difference in the passage of proper time at different positions as described by a metric tensor of spacetime. The existence of gravitational time dilation was first confirmed directly by the PoundRebka experiment in 1. DefinitioneditClocks that are far from massive bodies or at higher gravitational potentials run more quickly, and clocks close to massive bodies or at lower gravitational potentials run more slowly. For example, considered over the total lifetime of the earth 4. Gyr, a clock set at the peak of Mount Everest would be about 3. This is because gravitational time dilation is manifested in accelerated frames of reference or, by virtue of the equivalence principle, in the gravitational field of massive objects. According to general relativity, inertial mass and gravitational mass are the same, and all accelerated reference frames such as a uniformly rotating reference frame with its proper time dilation are physically equivalent to a gravitational field of the same strength. Let us consider a family of observers along a straight vertical line, each of whom experiences a distinct constant g force directed along this line e.

A common equation used to determine gravitational time dilation is derived from the Schwarzschild metric, which describes spacetime in the vicinity of a non rotating massive spherically symmetric object.

To illustrate then, without accounting for the effects of rotation, proximity to the Earths gravitational well will cause a clock on the planets surface to accumulate around 0. In comparison, a clock on the surface of the sun will accumulate around 6. Circular orbitseditIn the Schwarzschild metric, free falling objects can be in circular orbits if the orbital radius is larger than 3. The formula for a clock at rest is given above the formula below gives the gravitational time dilation for a clock in a circular orbit but it does not include the opposing time dilation caused by the clocks motion.

Important features of gravitational time dilationeditAccording to the general theory of relativity, gravitational time dilation is copresent with the existence of an accelerated reference frame. An exception is the center of a concentric distribution of matter, where there is no accelerated reference frame, yet clocks are still supposed to tick slowly. Additionally, all physical phenomena in similar circumstances undergo time dilation equally according to the equivalence principle used in the general theory of relativity. The speed of light in a locale is always equal to c according to the observer who is there. That is, every infinitesimal region of space time may be assigned its own proper time and the speed of light according to the proper time at that region is always c. This is the case whether or not a given region is occupied by an observer. Equinox Core Banking Software' title='Equinox Core Banking Software' />A time delay can be measured for photons which are emitted from Earth, bend near the Sun, travel to Venus, and then return to Earth along a similar path. There is no violation of the constancy of the speed of light here, as any observer observing the speed of photons in their region will find the speed of those photons to be c, while the speed at which we observe light travel finite distances in the vicinity of the Sun will differ from c. If an observer is able to track the light in a remote, distant locale which intercepts a remote, time dilated observer nearer to a more massive body, that first observer tracks that both the remote light and that remote time dilated observer have a slower time clock than other light which is coming to the first observer at c, like all other light the first observer really can observe at their own location. If the other, remote light eventually intercepts the first observer, it too will be measured at c by the first observer. Time dilation in a gravitational field is equal to time dilation in far space, due to a speed that is needed to escape that gravitational field. Here is the proof.
