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 ...
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.
At the time he only considered the time-dilating manifestation of gravity, which is the dominating contribution at non-relativistic speeds; however relativistic objects travel through space a comparable amount as they do though time, so purely spatial curvature becomes just as important.
Instead there are approximate inertial frames moving alongside freely falling particles. Translated into the language of spacetime: the straight time-like lines that define a gravity-free inertial frame are deformed to lines that are curved relative to each other, suggesting that the inclusion of gravity necessitates a change in spacetime geometry.
Note how the view of spacetime changes when the observer accelerates, changing the instantaneous inertial frame of reference. These changes are governed by the Lorentz transformations. Also note that: • the balls on the world line before/after future/past accelerations are more spaced out due to time dilation.
Time is a slippery thing, as profound thinkers like physicist Albert Einstein and, well, fictional time traveler Dr. Who plainly understood. Scientists made that point anew on Monday in a study ...
But time is weird, and there's another phenomenon called relative velocity time dilation that usurps gravity's effect. Why astronauts age slower Relative velocity time dilation is where time moves ...
Any theory of gravity will predict gravitational time dilation if it respects the principle of equivalence. [ 6 ] : 16 This includes Newtonian gravitation. A standard demonstration in general relativity is to show how, in the " Newtonian limit " (i.e. the particles are moving slowly, the gravitational field is weak, and the field is static ...
