Big′ Bang′


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.

The currently accepted standard big bang model of the universe (BBU) stands on two bases, which are (1) Einstein's general relativity (GR) that describes the effect of matter on spacetime and (2) the cosmological principle (CP) of spacetime isotropy and homogeneity that generates the Friedmann-Lemaitre-Robertson-Walker (FLRW) metric of spacetime [1-4].
