    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.

    Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology and epistemology of space and time.While such ideas have been central to philosophy from its inception, the philosophy of space and time was both an inspiration for and a central aspect of early analytic philosophy.

    The book starts by exploring the concept of time. Burkeman juxtaposes existence in the modern world to life before the invention of clocks.For the medieval farmer, work was infinite and life revolved around "task orientation": "the rhythms of life emerge organically from the tasks themselves".

  5. Absolute space and time - Wikipedia

    en.wikipedia.org/wiki/Absolute_space_and_time

    Absolute, true and mathematical time, of itself, and from its own nature flows equably without regard to anything external, and by another name is called duration: relative, apparent and common time, is some sensible and external (whether accurate or unequable) measure of duration by the means of motion, which is commonly used instead of true ...

    Europa's prime meridian is a line passing through this point. [41] Research suggests that tidal locking may not be full, as a non-synchronous rotation has been proposed: Europa spins faster than it orbits, or at least did so in the past. This suggests an asymmetry in internal mass distribution and that a layer of subsurface liquid separates the ...

  9. Hartle–Hawking state - Wikipedia

    en.wikipedia.org/wiki/Hartle–Hawking_state

    The precise form of the Hartle–Hawking state is the path integral over all D-dimensional geometries that have the required induced metric on their boundary. According to the theory, time , as it is currently observed, diverged from a three-state dimension after the universe was in the age of the Planck time .
