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 lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational ...
Daily time dilation (gain or loss if negative) in microseconds as a function of (circular) orbit radius r = rs/re, where rs is satellite orbit radius and re is the equatorial Earth radius, calculated using the Schwarzschild metric. At r ≈ 1.497 [Note 1] there is no time dilation. Here the effects of motion and reduced gravity cancel.
The measured change in rate was (29±1.5)×10 −14, consistent with the result of 30.7×10 −14 predicted by general relativity. [ 22 ] In 1976, Briatore and Leschiutta compared the rates of two cesium clocks, one in Turin 250 m (820 ft) above sea level, the other at Plateau Rosa 3,500 m (11,500 ft) above sea level.
In (1+1) dimensions, i.e. a space made of one spatial dimension and one time dimension, the metric for two bodies of equal masses can be solved analytically in terms of the Lambert W function. [11] However, the gravitational energy between the two bodies is exchanged via dilatons rather than gravitons which require three-space in which to ...
However, approximately 412 muons per hour arrived in Cambridge, resulting in a time dilation factor of 8.8 ± 0.8. Frisch and Smith showed that this is in agreement with the predictions of special relativity: The time dilation factor for muons on Mount Washington traveling at 0.995 c to 0.9954 c is approximately 10.2.
For Earth's surface with respect to infinity, z is approximately 7 × 10 −10 (the equivalent of a 0.2 m/s radial Doppler shift); for the Moon it is approximately 3 × 10 −11 (about 1 cm/s). The value for the surface of the Sun is about 2 × 10 −6 , corresponding to 0.64 km/s.

Objects are falling to the floor because the room is aboard a rocket in space, which is accelerating at 9.81 m/s 2, the standard gravity on Earth, and is far from any source of gravity. The objects are being pulled towards the floor by the same "inertial force" that presses the driver of an accelerating car into the back of their seat.
