  2. Time perception - Wikipedia

    en.wikipedia.org/wiki/Time_perception

    The most well-known version of this illusion is known as the stopped-clock illusion, wherein a subject's first impression of the second-hand movement of an analog clock, subsequent to one's directed attention (i.e., saccade) to the clock, is the perception of a slower-than-normal second-hand movement rate (the second-hand of the clock may ...

  3. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    Time dilation was used in the Doctor Who episodes "World Enough and Time" and "The Doctor Falls", which take place on a spaceship in the vicinity of a black hole. Due to the immense gravitational pull of the black hole and the ship's length (400 miles), time moves faster at one end than the other.

  4. Gravitational time dilation - Wikipedia

    en.wikipedia.org/wiki/Gravitational_time_dilation

    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 ...

  5. Why some airlines' planes fly slower than others - AOL

    Despite the occasional pilot informing passengers (proudly) of an intention to “make up time in the air,” people usually assume planes are going as fast as they safely can, like a speed limit ...

    Relative velocity time dilation is where time moves slower as you move faster. The classic example of this is the twin scenario . One twin blasts off in a spaceship traveling close to the speed of ...

  7. Insect cognition - Wikipedia

    en.wikipedia.org/wiki/Insect_Cognition

    Flies with impaired mushroom bodies cannot form an odour association [31] and cockroaches with impaired mushroom bodies cannot make use of spatial information to form memories about locations. [32] Electrophysiological underpinnings of the cognition in different parts of the insect brain can be studied by various techniques including in vivo ...

  8. Experimental testing of time dilation - Wikipedia

    As it is moving in S, we have γ>1, therefore its proper time is shorter with respect to time T. (For comparison's sake, another muon at rest on Earth can be considered, called muon-S. Therefore, its decay time in S is shorter than that of muon-S′, while it is longer in S′.) In S, muon-S′ has a longer decay time than muon-S.

  9. Twin paradox - Wikipedia

    en.wikipedia.org/wiki/Twin_paradox

    This is a different voyage than the one shown above, as both schemes take the same assumed total point-of-view time: T=12 (stay-at-home), resp τ=12 (ship), so the results of the calculated other-one's times must be different: τ=9.33 (ship), resp T=17.3 (stay at home). In the standard proper time formula
