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 ...
There are two kinds of predicted gravitational memory effect: one based on a linear approximation of Einstein's equations, first proposed in 1974 by the Soviet scientists Yakov Zel'dovich and A. G. Polnarev, [2] [6] developed also by Vladimir Braginsky and L. P. Grishchuk, [2] and a non-linear phenomenon known as the non-linear memory effect, which was first proposed in the 1990s by Demetrios ...
At the same time, gravity will attempt to contract the system even further, and will do so on a free-fall time = / /, where is the universal gravitational constant, is the gas density within the region, and = / is the gas number density for mean mass per particle (μ = 3.9 × 10 −24 g is appropriate for molecular hydrogen with 20% helium by ...
Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity). When unspecified, "time dilation" usually refers to the effect due to velocity.
In order to map a body's gravitational influence, it is useful to think about what physicists call probe or test particles: particles that are influenced by gravity, but are so small and light that we can neglect their own gravitational effect. In the absence of gravity and other external forces, a test particle moves along a straight line at a ...

Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of gravity. [1] Gravitational collapse is a fundamental mechanism for structure formation in the universe.
After Coop and Amelia leave Earth, Murph becomes a scientist and helps Dr. Brand with his gravity manipulation equation; as an adult, she's still devoted to solving it so that she can reunite with ...
