  2. Kappa effect - Wikipedia

    en.wikipedia.org/wiki/Kappa_effect

    The kappa effect or perceptual time dilation [1] is a temporal perceptual illusion that can arise when observers judge the elapsed time between sensory stimuli applied sequentially at different locations. In perceiving a sequence of consecutive stimuli, subjects tend to overestimate the elapsed time between two successive stimuli when the ...

  3. Time perception - Wikipedia

    en.wikipedia.org/wiki/Time_perception

    The Kappa effect or perceptual time dilation [55] is a form of temporal illusion verifiable by experiment. [56] The temporal duration between a sequence of consecutive stimuli is thought to be relatively longer or shorter than its actual elapsed time, due to the spatial/auditory/tactile separation between each consecutive stimuli.

  4. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    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.

    To test the time dilation part of the TSR massive experiments had to be conducted. In 1971, the Hafele (ha-fi-la) and Keating Experiment flew four atomic clocks on airplanes going around the world ...

  6. Ferocious black holes reveal 'time dilation' in early universe

    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 ...

  7. Twin paradox - Wikipedia

    en.wikipedia.org/wiki/Twin_paradox

    This combines the effects of time dilation due to motion (by factor α = 0.6, five years on Earth are 3 years on ship) and the effect of increasing light-time-delay (which grows from 0 to 4 years). Of course, the observed frequency of the transmission is also 1 ⁄ 3 the frequency of the transmitter (a reduction in frequency; "red-shifted").

  8. Chronostasis - Wikipedia

    en.wikipedia.org/wiki/Chronostasis

    Chronostasis (from Greek χρόνος, chrónos, 'time' and στάσις, stásis, 'standing') is a type of temporal illusion in which the first impression following the introduction of a new event or task-demand to the brain can appear to be extended in time. [1] For example, chronostasis temporarily occurs when fixating on a target stimulus ...

  9. Einstein's thought experiments - Wikipedia

    en.wikipedia.org/wiki/Einstein's_thought_experiments

    Let us recall, for example, the electrodynamic interaction between a magnet and a conductor. The observable phenomenon depends here only on the relative motion of conductor and magnet, while according to the customary conception the two cases, in which, respectively, either the one or the other of the two bodies is the one in motion, are to be ...
