  2. History of communication - Wikipedia

    en.wikipedia.org/wiki/History_of_communication

    The development of communication in its oral form can be based on certain historical periods. The complexity of oral communication has always been reflective based on the circumstance of the time period. Verbal communication was never bound to one specific area, instead, it had and continues to be a globally shared tradition of communication. [11]

  3. 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 ...

  4. Time in physics - Wikipedia

    en.wikipedia.org/wiki/Time_in_physics

    is the time between two events as measured in the moving reference frame in which they occur at the same place (e.g. two ticks on a moving clock); it is called the proper time between the two events; t is the time between these same two events, but as measured in the stationary reference frame;

    “The only reason for time is so that everything doesn't happen at once.” — Albert Einstein This insightful reflection by Einstein subtly cues us into the multidimensional and enigmatic ...

    Time: The interval between two events present on the worldline of a single clock is called proper time, an important invariant of special relativity. As the origin of the muon at A and the encounter with Earth at D is on the muon's worldline, only a clock comoving with the muon and thus resting in S′ can indicate the proper time T′ 0 =AD.

    In Liu Cixin's novel The Three-Body Problem, the alien Trisolarans, while preparing to invade the Solar System, use a device with Ansible characteristics to communicate with their collaborators on Earth in real time. Additionally, they use spying/sabotaging devices called 'Sophons' on Earth which by penetration can access any kind of ...

  8. Problem of time - Wikipedia

    en.wikipedia.org/wiki/Problem_of_time

    The field equations of general relativity are not parameterized by time but formulated in terms of spacetime. Many of the issues related to the problem of time exist within general relativity. At the cosmic scale, general relativity shows a closed universe with no external time. These two very different roles of time are incompatible. [4]
