  2. 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.

  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 ...

    The space station is whizzing around Earth at about five miles per second (18,000 mph), according to NASA. That means time moves slower for the astronauts relative to people on the surface. Now ...

  5. 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.

  6. Special relativity - Wikipedia

    en.wikipedia.org/wiki/Special_relativity

    In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time.In Albert Einstein's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates: [p 1] [1] [2]

  8. Gravitational wave - Wikipedia

    en.wikipedia.org/wiki/Gravitational_wave

    This type of instrument was the first type of gravitational wave detector. Strains in space due to an incident gravitational wave excite the bar's resonant frequency and could thus be amplified to detectable levels. Conceivably, a nearby supernova might be strong enough to be seen without resonant amplification.

  9. Speed of light - Wikipedia

    en.wikipedia.org/wiki/Speed_of_Light

    In the theory of relativity, c interrelates space and time and appears in the famous mass–energy equivalence, E = mc 2. [7] In some cases, objects or waves may appear to travel faster than light (e.g., phase velocities of waves, the appearance of certain high-speed astronomical objects, and particular quantum effects).
