What is "big bang"

big bang \big bang\ n. (Astron.) The explosive event marking the beginning of the known universe, according to big bang theory; the beginning of time.

Note: The big bang is likened to a massive explosion from a point containing all of the matter and energy of the beginning universe, which started the expansion and evolution of the universe which continues today. The evidence for such an event includes the apparently expanding size of the present universe, and a background microwave radiation of about 3[deg] Kelvin, equal to that predicted from mathematical models of such an explosive event.

hypothetical explosive beginning of the universe, developed from the work of Monsignor Georges Henri Joseph Édouard Lemaître and George Gamow, the name first attested 1950 (said to have been used orally 1949) by British astronomer Fred Hoyle (1915-2001) in an attempt to explain the idea in laymen's terms.

n. The cosmic event that marks the beginning of time and the rapid expansion of space for the visible universe. The evolution of the universe since that beginning point is described by the Big Bang Theory.

n. (cosmology) the cosmic explosion that is hypothesized to have marked the origin of the universe

The Big Bang theory is the prevailing cosmological model for the universe from the earliest known periods through its subsequent large-scale evolution. The model accounts for the fact that the universe expanded from a very high density and high temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background, large scale structure and Hubble's Law. If the known laws of physics are extrapolated beyond where they have been verified, there is a singularity. Some estimates place this moment at approximately 13.8 billion years ago, which is thus considered the age of the universe. After the initial expansion, the universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies.

Since Georges Lemaître first noted, in 1927, that an expanding universe might be traced back in time to an originating single point, scientists have built on his idea of cosmic expansion. While the scientific community was once divided between supporters of two different expanding universe theories, the Big Bang and the Steady State theory, accumulated empirical evidence provides strong support for the former. In 1929, from analysis of galactic redshifts, Edwin Hubble concluded that galaxies are drifting apart; this is important observational evidence consistent with the hypothesis of an expanding universe. In 1965 the cosmic microwave background radiation was discovered, which was crucial evidence in favor of the Big Bang model, since that theory predicted the existence of background radiation throughout the universe before it was discovered. More recently, measurements of the redshifts of supernovae indicate that the expansion of the universe is accelerating, an observation attributed to dark energy's existence. The known physical laws of nature can be used to calculate the characteristics of the universe in detail back in time to an initial state of extreme density and temperature.

The Big Bang is a Milestone Comics event published by DC Comics. The event was first chronicled in Blood Syndicate #1 by Dwayne McDuffie, Ivan Velez Jr. and Denys Cowan, and Static #1 (April 1993) by Dwayne McDuffie and Robert L. Washington III.

The Big Bang was, according to the prevailing cosmological theory of the universe's early development, the event that led to the formation of the universe.

Big Bang may also refer to:

Big Bang: The most important scientific discovery of all time and why you need to know about it is a book written by Simon Singh and published in 2004 by Fourth Estate.

Big Bang chronicles the history and development of the Big Bang model of the universe, from the ancient Greek scientists who first measured the distance to the sun to the 20th century detection of the cosmic radiation still echoing the dawn of time.

The book discusses how different theories of the universe evolved, along with a personal look at the people involved.

Big Bang (; lit. "I'll Shoot") is a 2007 South Korean action-comedy film written and directed by Park Jung-woo, and starring Kam Woo-sung and Kim Su-ro.

Big Bang is the debut album by the American metal band Magdallan, released in 1992 through Intense Records. Big Bang was nominated for one GMA Dove Award for Best Metal/Hard Rock Album in 1992, but did not win.

Big Bang is the seventh album from Latin rock band Enanitos Verdes released on August 15, 1994. "Lamento Boliviano" was released as a single.

Big Bang is the fifth studio album by Brazilian rock band Os Paralamas do Sucesso. It was released in November 20, 1989.

Main hits of this album include "Lanterna dos Afogados" (the most famous and well-known song by the Paralamas), "Nebulosa do Amor" and "Jubiabá" (a Portuguese-language adaptation of Alan Robert's and Lord Kitchner's "Give Me the Things").

The phrase Big Bang, used in reference to the sudden deregulation of financial markets, was coined to describe measures, including abolition of fixed commission charges and of the distinction between stockjobbers and stockbrokers on the London Stock Exchange and change from open-outcry to electronic, screen-based trading, effected by Margaret Thatcher in 1986.

The Big Bang was the result of an agreement in 1983 by the Thatcher government and the London Stock Exchange to settle a wide-ranging anti-trust case that had been initiated during the previous government by the Office of Fair Trading against the London Stock Exchange under the Restrictive Trade Practices Act 1956. These restrictive practices included the London Stock Exchange's rules establishing fixed minimum commissions, the 'single capacity' rule (which enforced a separation between brokers acting as agents for their clients on commission and jobbers who made the markets and theoretically provided liquidity by holding lines of stocks and shares on their books), the requirement that both brokers and jobbers should be independent and not part of any wider financial group, and the stock exchange's exclusion of all foreigners from stock exchange membership.

The day the London Stock Exchange's rules changed on 27 October 1986 was dubbed the "Big Bang" because of the increase in market activity expected from an aggregation of measures designed to alter the structure of the financial market.

The effect of the Big Bang led to significant changes to the structure of the financial markets in London. The changes saw many of the old firms being taken over by large banks both foreign and domestic and would lead in the following years to further changes to the regulatory environment that would eventually lead to the creation of the Financial Services Authority.

Big Bang ( Korean: ) is a South Korean boy band formed by YG Entertainment. Consisting of members G-Dragon, T.O.P, Taeyang, Daesung, and Seungri, the group officially debuted on August 19, 2006. Predominantly a hip hop group, their debut was a moderate success, with their first self-titled Korean album selling 48,000 copies. Their breakthrough came with the release of their first extended play, Always (2007), which included the number one song "Lies" ( Korean: ; Revised Romanization: Geojitmal). The song went on to top major Korean music charts for a record-breaking seven consecutive weeks, and won the group the Song of the Year award at the 9th Mnet Korean Music Festival.

Big Bang’s followed-up releases furthered their success and popularity: Hot Issue (2007) spawned the chart-topping song "Last Farewell," (Korean: ; Revised Romanization: Majimak Insa), while Stand Up (2008) produced "Day By Day" (Korean: ; Revised Romanization: Haru Haru). After receiving the Artist of the Year award from the 2008 Mnet Korean Music Festival, the group expanded their endeavors to Japan, releasing both their second Korean studio-album Remember and their first Japanese album, Number 1, in the same year, and consequently winning three awards at the 9th MTV Video Music Awards Japan. They would go on to release three more Japanese studio albums: Big Bang (2009), Big Bang 2 (2011), and the Japanese studio album Alive (2012). Amidst their Japanese promotions, the members branched out to do solo activities: Taeyang and G-Dragon released solo albums, G-Dragon and T.O.P formed a sub-unit, Seungri and Daesung acted in musicals and hosted variety shows, and T.O.P went on to star in various films and television shows.

After a two-year hiatus in South Korea, Big Bang reunited in 2011 with their EP Tonight (2011). Promotions were cut short when multiple members encountered legal issues. By the end of the year, Big Bang emerged as the inaugural Best Worldwide Act winner at the 2011 MTV Europe Music Awards. Three months after their win in Europe, Big Bang released their most successful physical album, the Korean EP Alive (2012), which won them their second Artist of the Year Award at the 14th Mnet Asian Music Award. Alive became the first Korean album to chart on Billboard 200, with the group embarking on their first ever world tour that concluded in early 2013. In 2015, after a three-year hiatus, Big Bang made their highly anticipated comeback to their native country with the release of four singles, " M," " A," " D," and " E," to precede their third Korean studio album Made. Their singles were met with critical and commercial success, netting in sales of over 13.3 million copies throughout Asia and winning the group their third Artist of the Year Award at the 17th Mnet Asian Music Awards.

Labeled as the "Kings of K-pop" and "Nation's Boy Band," the members’ involvement in composing and producing their own music, most notably G-Dragon, has earned the group respect and praise from the music industry. Since the release of the Gaon Chart, Big Bang, including their solo releases, has sold over 79 million records. With the previous releases including sales from Music Industry Association of Korea (MIAK) and The Korea Music Content Industry Association (KMCIA), they have sold over 100 million records, with over 94 million digital singles, selling an average of 4.3 million downloads per title track and 1.5 million downloads per non-title track, and over 6 million albums in Korea, Japan, and the rest of the Asian continent. They have won numerous awards and set several records, including the all-time best-selling artist in Cyworld and most Artist of the Year Award wins at the Mnet Asian Music Awards. Citing their global popularity and contribution to K-pop, the Hollywood Reporter have described them as "the biggest boy band in the world."

"Bigbang" or "We Belong Together", also referred to as "First Single" is the first single by the South Korean hip-hop boy band Big Bang. It comes as a CD-and-DVD combo including extra documentary material. It was released by the YG Entertainment label and remained in the charts for eight months. The band's members – G-Dragon, Taeyang, Seungri, Daesung, and T.O.P – composed it. Band leader G-Dragon composed the principal track "We Belong Together"; he and T.O.P. wrote the lyrics. It presents a rhythmic up-tempo tune with rap passages. The song This Love is a remake of the song of the same name by Maroon 5.

Big Bang (another name: 1st Japanese Album) is the second studio Japanese album by South Korean boy band, Big Bang and was released on August 19, 2009.
