  2. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    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.

    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 ...

  4. Intrinsic and extrinsic ageing - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_and_extrinsic_ageing

    Intrinsic and extrinsic ageing. Intrinsic ageing and extrinsic ageing are terms used to describe cutaneous ageing of the skin and other parts of the integumentary system, which while having epidermal concomitants, seems to primarily involve the dermis. [1] Intrinsic ageing is influenced by internal physiological factors alone, and extrinsic ...

    Decay time of muons: The time dilation formula is , where T0 is the proper time of a clock comoving with the muon, corresponding with the mean decay time of the muon in its proper frame. As the muon is at rest in S′, we have γ=1 and its proper time T′0 is measured. As it is moving in S, we have γ>1, therefore its proper time is shorter ...

    The effect get's stronger as you go faster. A German study published this week has shown you can create the time dilation effect in the lab! Which is HUGE news for physics.

  8. Kappa effect - Wikipedia

    en.wikipedia.org/wiki/Kappa_effect

    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 ...

  9. Gravitational time dilation - Wikipedia

    en.wikipedia.org/wiki/Gravitational_time_dilation

    Special relativity. 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 ...
