  2. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    Also, a climber's time is theoretically passing slightly faster at the top of a mountain compared to people at sea level. It has also been calculated that due to time dilation, the core of the Earth is 2.5 years younger than the crust. [34] "A clock used to time a full rotation of the Earth will measure the day to be approximately an extra 10 ...

  3. 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 ...

  4. Shapiro time delay - Wikipedia

    en.wikipedia.org/wiki/Shapiro_time_delay

    The Shapiro time delay effect, or gravitational time delay effect, is one of the four classic Solar System tests of general relativity. Radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present.

  5. Why scientists say we need to send clocks to the moon - AOL

    And it was Einstein’s theory of general relativity that explained why time passes slightly more slowly at lower elevations — because gravity ... Time also passes slower the faster a person or ...

    We perceive fewer “frames-per-second” as we get older, and therefore time feels like it’s passing quicker. It’s like a flipbook – the fewer the number of pictures, the quicker you flick ...

  7. Time perception - Wikipedia

    en.wikipedia.org/wiki/Time_perception

    This means that time appears to pass in proportion to the square root of the perceiver's real age, rather than directly proportional. Under this model, a 55-year-old would subjectively experience time passing ⁠2 + 1 / 4 ⁠ times more quickly than an 11-year-old, rather than five times under the previous. This means the following periods in ...

    A new study shows that being in lockdown due to the coronavirus is affecting people’s perception of how slowly — or quickly — time is passing by.

  9. Time travel - Wikipedia

    en.wikipedia.org/wiki/Time_travel

    Time travel is the hypothetical activity of traveling into the past or future. Time travel is a concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time ...
