n. (sometimes l.c.) the cosmic explosion of matter postulated by the big bang theory. [1950–55] big bang (bĭg) The violent explosion of an extremely small, hot, and dense body of matter between 12 and 18 billion years ago. It is viewed as the earliest event in a widely held model of the origin of the universe. Compare steady state universe.Did You Know? It's a chilling thought: In the 1920s, astronomers found that wherever they looked in space, distant galaxies were rapidly moving away from Earth. In other words, the universe was getting larger and larger. By calculating the speed of several galaxies and working back from there, astronomers learned that this expansion began between 12 and 18 billion years ago, when the entire universe was smaller than a dime and almost infinitely dense. According to the widely accepted theory of the big bang, a massive explosion kicked off the expansion and was the origin of space and time. Now scientists must figure out how much mass the universe contains in order to see what lies ahead. If there is enough mass, the gravity attracting all the pieces to each other will eventually stop the expansion and pull all the pieces of the universe back together in a "big crunch." The universe would then be a closed universe. However, there may not be enough mass to support a universe that is closed. If that is the case, then an open universe would expand forever, and all the galaxies and stars would drift away from each other and become dark and cold.big bangThe day in 1986 when, in the course of one day, the London Stock Exchange was deregulated and new computing technology brought in.Thesaurus| Noun | 1. | big bang - (cosmology) the cosmic explosion that is hypothesized to have marked the origin of the universecosmogeny, cosmogony, cosmology - the branch of astrophysics that studies the origin and evolution and structure of the universeblowup, detonation, explosion - a violent release of energy caused by a chemical or nuclear reaction |

Big BangThe term applied to the liberalization in 1986 of the London Stock Exchange (LSE) when trading was automated.Big BangAn informal term referring to the deregulation of the London Stock Market on October 27, 1986. On that date, a number of changes occurred, including a shift from an open outcry system to an electronic exchange. Perhaps most important, however, was the abolition of fixed commissions, which completely changed the way brokers on the London Stock Market conducted their business. Big Bang significantly increased the volume on the London Stock Exchange and reversed its trend of falling behind other world stock markets. It was a major part of Prime Minister Margaret Thatcher's financial reform program.
It is important to note that one does not refer to Big Bang as the Big Bang.Big Bang The date, October 27, 1986, on which the London security markets were significantly deregulated. The deregulation eliminated fixed commissions on security trades and put an end to the prohibition against securities firms acting as brokers and dealers.big bang see STOCK EXCHANGE.AcronymsSeebaseballbig bang
