The Hitchhiker's Guide to the Galaxy is a comic science fiction series created by Douglas Adams . Originally a radio comedy broadcast on BBC Radio 4 in 1978, later it was adapted to other formats, and over several years it gradually became an international multi-media phenomenon. Adaptations have included stage shows , a "trilogy" of five books published between 1979 and 1992, a sixth novel penned by Eoin Colfer in 2009, a 1981 TV series , a 1984 computer game , and three series of three-part comic book adaptations of the first three novels published by DC Comics between 1993 and 1996.
Diamagnetic Gravity Vortexes by Richard LeFors Clark Waves of gravity pour from an extraordinary (and imaginary) cosmic accident —a head-on collision of two black holes approaching from left and right. Kenneth Eppley and Larry Smarr used a computer to calculate and draw contours of the variable curvature of space that constitutes the radiation.
Gravitation , or gravity , is the natural phenomenon by which physical bodies appear to attract each other with a force proportional to their masses . It is most commonly experienced as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. The phenomenon of gravitation itself, however, is a byproduct of a more fundamental phenomenon described by general relativity , which suggests that spacetime is curved according to the energy and momentum of whatever matter and radiation are present.
The Universe is commonly defined as the totality of existence, [ 1 ] [ 2 ] [ 3 ] [ 4 ] including planets , stars , galaxies , the contents of intergalactic space , and all matter and energy . [ 5 ] [ 6 ] The broadest definition of universe is that it is simply everything, while a narrower definition is that the universe is limited to what can be observed. [ dubious ] Similar terms include the cosmos , the world and nature . Scientific observation of the Universe, the observable part of which is about 93 billion light years in diameter, [ 7 ] has led to inferences of its earlier stages. These observations suggest that the Universe has been governed by the same physical laws and constants throughout most of its extent and history. The Big Bang theory is the prevailing cosmological model that describes the early development of the Universe, which in physical cosmology is calculated to have occurred 13.798 ± 0.037 billion years ago.

In the general sense, a cosmos is an orderly or harmonious system . The word derives from the Greek term κόσμος ( kosmos ), literally meaning "order" or "ornament" and metaphorically "world", [ 1 ] and is antithetical to the concept of chaos . Today, the word is generally used as a synonym of the Latin loanword " Universe " (considered in its orderly aspect). The word cosmetics originates from the same root. In many Slavic languages such as Russian , Bulgarian , and Serbian , the word Космос cosmos means also the " outer space ". In Mandarin Chinese , cosmos and universe are both translated as 宇宙 yǔzhòu , which literally translated means space-time (宇 yǔ = space + 宙 zhòu = time).
I was at a talk the other night listening to a nervous grad student present a paper about knots when, for whatever reason – I was thinking about Michael Heizer – wham! An idea came to me: The eccentric son of a billionaire takes his share of the family fortune and moves to Utah. He buys loads and loads of land, tens of thousands of acres – and, with it, huge digging machines. This includes state of the art tunnelers, taken straight from the oil industry. [Image: Create 3D ]. For the next forty years, one thousand feet below the surface of the earth, he carves every knot known to mathematics, straight through the Jurassic bedrock.
