  2. Light cone - Wikipedia

    en.wikipedia.org/wiki/Light_cone

    If one imagines the light confined to a two-dimensional plane, the light from the flash spreads out in a circle after the event E occurs, and if we graph the growing circle with the vertical axis of the graph representing time, the result is a cone, known as the future light cone. The past light cone behaves like the future light cone in ...

    Figure 2–4. The light cone centered on an event divides the rest of spacetime into the future, the past, and "elsewhere" In Fig. 2–4, event O is at the origin of a spacetime diagram, and the two diagonal lines represent all events that have zero spacetime interval with respect to the origin event.

  5. A series and B series - Wikipedia

    en.wikipedia.org/wiki/A_series_and_B_series

    In the first mode, events are ordered as future, present, and past.Futurity and pastness allow of degrees, while the present does not. When we speak of time in this way, we are speaking in terms of a series of positions which run from the remote past through the recent past to the present, and from the present through the near future all the way to the remote future.

  6. Temporality - Wikipedia

    en.wikipedia.org/wiki/Temporality

    Examples in continental philosophy of philosophers raising questions of temporality include Edmund Husserl's analysis of internal time consciousness, Martin Heidegger's Being and Time, J. M. E. McTaggart's article "The Unreality of Time", George Herbert Mead's Philosophy of the Present, and Jacques Derrida's criticisms of Husserl's analysis.

  7. Time - Wikipedia

    en.wikipedia.org/wiki/Time

    Time is the continuous progression of 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 in the ...

    Therefore, the future value of your annuity due with $1,000 annual payments at a 5 percent interest rate for five years would be about $5,801.91.

  9. Temporal paradox - Wikipedia

    en.wikipedia.org/wiki/Temporal_paradox

    Temporal paradoxes fall into three broad groups: bootstrap paradoxes, consistency paradoxes, and Newcomb's paradox. [1] Bootstrap paradoxes violate causality by allowing future events to influence the past and cause themselves, or "bootstrapping", which derives from the idiom "pull oneself up by one's bootstraps."
