Last Contact
"Last Contact" is a science fiction short story published in 2007 by Stephen Baxter. It was nominated for the 2008 Hugo Award for Best Short Story. Plot A mother and daughter, Maureen and 35-year-old Caitlin, live through the last few months of Earth's existence. Maureen and her late husband Harry are described as having substantial astrophysical knowledge. Caitlin, an astrophysicist herself, has been involved with the recent discovery of the Big Rip, a field of dark energy that is essentially tearing the universe apart. With distant galaxies disappearing from view in deep field images, scientists have determined that the effect will culminate in a matter of months, unbeknownst to the general public. On March 15, Caitlin participated in a BBC Radio 4 discussion about the discovery, revealing it to the public. On June 5, amid their search for extraterrestrial intelligence as part of the Rip, distinctly shaped signals were detected. Caitlin reveals that she was invited to a shelt ...

Stephen Baxter (author)
Stephen Baxter (born 13 November 1957) is an English hard science fiction author. He has degrees in mathematics and engineering. Writing style Strongly influenced by science fiction pioneer H. G. Wells, Baxter has been vice-president of the international H. G. Wells Society since 2006. His fiction falls into three main categories of original work plus a fourth category, extending other authors' writing; each has a different basis, style, and tone. Baxter's "Future history, Future History" mode is based on research into hard science fiction, hard science. It encompasses the ''Xeelee Sequence'', which consists of nine novels (including the ''Destiny's Children'' trilogy and Vengeance/Redemption duology that is set in alternate timeline), plus three volumes collecting the 52 short pieces (short stories and novellas) in the series, all of which fit into a single timeline stretching from the Big Bang singularity of the past to his ''Timelike Infinity'' (1993) singularity of the fu ...

Science Fiction
Science fiction (often shortened to sci-fi or abbreviated SF) is a genre of speculative fiction that deals with imaginative and futuristic concepts. These concepts may include information technology and robotics, biological manipulations, space exploration, time travel, Parallel universes in fiction, parallel universes, and extraterrestrials in fiction, extraterrestrial life. The genre often explores human responses to the consequences of projected or imagined scientific advances. Science fiction is related to fantasy (together abbreviated wikt:SF&F, SF&F), Horror fiction, horror, and superhero fiction, and it contains many #Subgenres, subgenres. The genre's precise Definitions of science fiction, definition has long been disputed among authors, critics, scholars, and readers. Major subgenres include hard science fiction, ''hard'' science fiction, which emphasizes scientific accuracy, and soft science fiction, ''soft'' science fiction, which focuses on social sciences.

Short Story
A short story is a piece of prose fiction. It can typically be read in a single sitting and focuses on a self-contained incident or series of linked incidents, with the intent of evoking a single effect or mood. The short story is one of the oldest types of literature and has existed in the form of legends, Myth, mythic tales, Folklore genre, folk tales, fairy tales, tall tales, fables, and anecdotes in various ancient communities around the world. The modern short story developed in the early 19th century. Definition The short story is a crafted form in its own right. Short stories make use of plot, resonance and other dynamic components as in a novel, but typically to a lesser degree. While the short story is largely distinct from the novel or novella, novella/short novel, authors generally draw from a common pool of literary techniques. The short story is sometimes referred to as a genre. Determining what exactly defines a short story remains problematic. A classic definition ...

Hugo Award For Best Short Story
The Hugo Award for Best Short Story is one of the Hugo Awards given each year for science fiction or fantasy stories published or translated into English during the previous calendar year. The short story award is available for works of fiction of fewer than 7,500 words; awards are also given out for pieces of longer lengths in the novelette, novella, and novel categories. The Hugo Awards have been described as "a fine showcase for speculative fiction" and "the best known literary award for science fiction writing". The Hugo Award for Best Short Story has been awarded annually since 1955, except in 1957. The award was titled "Best Short Fiction" rather than "Best Short Story" in 1960–1966. During this time no Novelette category was awarded and the Novella category had not yet been established; the award was defined only as a work "of less than novel length" that was not published as a stand-alone book. In addition to the regular Hugo awards, beginning in 1996 Retrospective H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Rip
In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase. According to the standard model of cosmology, the scale factor of the universe is accelerating, and, in the future era of cosmological constant dominance, will increase exponentially. But this expansion is similar for every moment of time (hence the exponential law—the expansion of a local volume is the same number of times over the same time interval), and is characterized by an unchanging, small Hubble constant, effectively ignored by any bound material structures. By contrast, in the Big Rip scenario the Hubble constant increases to infinity in a finite time. According to recent studie ...

Dark Energy
In physical cosmology and astronomy, dark energy is a proposed form of energy that affects the universe on the largest scales. Its primary effect is to drive the accelerating expansion of the universe. It also slows the rate of structure formation. Assuming that the lambda-CDM model of cosmology is correct, dark energy dominates the universe, contributing 68% of the total energy in the present-day observable universe while dark matter and Baryon#Baryonic matter, ordinary (baryonic) matter contribute 27% and 5%, respectively, and other components such as neutrinos and photons are nearly negligible.Sean Carroll, Ph.D., Caltech, 2007, The Teaching Company, ''Dark Matter, Dark Energy: The Dark Side of the Universe'', Guidebook Part 2. p. 46.

Search For Extraterrestrial Intelligence
The search for extraterrestrial intelligence (usually shortened as SETI) is an expression that refers to the diverse efforts and scientific projects intended to detect extraterrestrial signals, or any evidence of intelligent life beyond Earth. Researchers use methods such as monitoring electromagnetic radiation, searching for optical signals, and investigating potential extraterrestrial artifacts for any signs of transmission from civilizations present on other planets. Some initiatives have also attempted to send messages to hypothetical alien civilizations, such as NASA's Voyager Golden Record, Golden Record. Modern SETI research began in the early 20th century after the advent of radio, expanding with projects like Project Ozma, the Wow! signal detection, and the Breakthrough Listen initiative; a $100 million, 10-year attempt to detect signals from nearby stars, announced in 2015 by Stephen Hawking and Yuri Milner. Since the 1980s, international efforts have been ongoing, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pergola
A pergola is most commonly used as an outdoor garden feature forming a shaded walkway, passageway, or sitting area of vertical posts or pillars that usually support crossbeams and a sturdy open lattice, often upon which woody vines are trained. The origin of the word is the Late Latin ''pergula'', referring to a projecting eave. It also may be an extension of a building or serve as protection for an open terrace or a link between pavilions. They are different from green tunnels, with a green tunnel being a type of road under a canopy of trees. Depending on the context, the terms "pergola", "bower", and "arbor" are often used interchangeably. An "arbor" is also regarded as being a wooden bench seat with a roof, usually enclosed by lattice panels forming a framework for climbing plants; in evangelical Christianity, brush arbor revivals occur under such structures. A pergola, on the other hand, is a much larger and more open structure. Normally, a pergola does not include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
