In cosmology, a Hubble volume (named for the astronomer Edwin Hubble) or Hubble sphere, Hubble bubble, subluminal sphere, causal sphere and sphere of causality is a spherical region of the observable universe surrounding an observer beyond which objects recede from that observer at a rate greater than the speed of light due to the expansion of ...
"The Wind" shows great inventiveness in its choice of metaphors and similes, while employing extreme metrical complexity. [9] It is one of the classic examples [10] [11] of the use of what has been called "a guessing game technique" [12] or "riddling", [13] a technique known in Welsh as dyfalu, comprising the stringing together of imaginative and hyperbolic similes and metaphors.
The spatial region from which we can receive light is called the observable universe. The proper distance (measured at a fixed time) between Earth and the edge of the observable universe is 46 billion light-years [50] [51] (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).

The poem features in several parts of the book, each with slightly different wording or different punctuation; the poem's definite composition is unsure. With Ananda** in this fateful hour, I place all Heaven with its power, And the sun with its brightness, And the snow with its whiteness, And the fire with all the strength it hath,
The English poet Alfred Noyes was present for the "first light" of the Hooker telescope on November 2, 1917. Noyes used this night as the setting in the opening of Watchers of the Sky, the first volume in his trilogy The Torchbearers, an epic poem about the history of science. According to his account of the night, the first object viewed in ...
Hubble radius, Hubble sphere (not to be confused with a Hubble bubble), Hubble volume, or Hubble horizon is a conceptual horizon defining the boundary between particles that are moving slower and faster than the speed of light relative to an observer at one given time. Note that this does not mean the particle is unobservable; the light from ...
Anne Marriott (November 5, 1913 – October 10, 1997) [1] was a Canadian writer who won the Governor General's Award for her book Calling Adventurers! "She was renowned especially for the narrative poem The Wind, Our Enemy," which she wrote while still in her twenties.
The poem begins with three sections describing the wind's effects upon earth, air, and ocean. In the last two sections, the poet speaks directly to the wind, asking for its power, to lift him up and make him its companion in its wanderings. The poem ends with an optimistic note which is that if winter days are here then spring is not very far.
