  2. Temporal finitism - Wikipedia

    en.wikipedia.org/wiki/Temporal_finitism

    Temporal finitism is the doctrine that time is finite in the past. [clarification needed] The philosophy of Aristotle, expressed in such works as his Physics, held that although space was finite, with only void existing beyond the outermost sphere of the heavens, time was infinite.

  3. List of relativistic equations - Wikipedia

    This observer finds that time t passed between the front of the train passing the post, and the back of the train passing the post. Because the two events - the passing of each end of the train by the post - occurred in the same place in the ground observer's frame, the time this observer measured is the proper time. So:

  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. 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.

    At this time estimate, Flight 11 is about to descend over New York and is just minutes away from crashing. 8:46:40: Flight 11 crashes into the north face of the North Tower (1 WTC) of the World Trade Center, between floors 93 and 99. All passengers aboard are instantly killed with an unknown number inside the building.

  7. Time - Wikipedia

    en.wikipedia.org/wiki/Time

    Time is the continuous progression of our changing existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. [1] [2] [3] It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or ...

  8. 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

    "All my possessions for a moment of time." [11]: 53 [15]: 16 [17] [68] [76] [102] [note 72] — Elizabeth I, queen regnant of England (24 March 1603) "I cannot bear that any misunderstanding should subsist between you and those who have for so many years shared in my toils and been the companions of my glory."
