The term "Big Bang" implies an explosion of matter into pre-existing space, but the theory actually indicates that space is dynamic and more space is constantly created in the interstices between particles as the density of the universe falls.  Big Bang theorists state that the Hubble [[redshift]] is a consequence of this stretching of the fabric of space.

Revision as of 21:21, May 9, 2007

According to the Big Bang theory, the universe emerged from an extremely dense and hot state called the original singularity.
According to the Big Bang theory, the 3 possible geometry of the universe depends on value of the cosmological constant.

The Big Bang Theory is the current dominant scientific theory explaining the creation of the Universe. It models the Universe as expanding from a very hot, dense state approximately 13.7 billion years ago. It was first proposed by Georges-Henri Lemaitre and evidence for the expansion was observed by Edwin Hubble[1]. Later George Gamow predicted that the Big Bang would leave an observable microwave background radiation (or CMBR). This radiation was subsequently discovered by Bell Labs and found to be close to that predicted by Gamow (Gamow predicted a background radiation level equivalent to a roughly 3K black body object, and the observed level is that of a 2.725K body).

The term "Big Bang" implies an explosion of matter into pre-existing space, but the theory actually indicates that space is dynamic and more space is constantly created in the interstices between particles as the density of the universe falls. Big Bang theorists state that the Hubble redshift is a consequence of this stretching of the fabric of space.

Supporters of the Big Bang Theory state that observations of distant supernovae and active galactic nuclei (AGN) indicate that the Universe is actually undergoing accelerated expansion[2][3] and that galaxy surveys[4][5] and recent observations of the microwave background[6][7] have corroborated these claims. Conventional wisdom is that the acceleration is caused by some sort of dark energy, which has not yet been directly observed.

Big Bang Theory Dissent Letter

The Big Bang Theory has had many dissenters including the British astronomer Sir Fred Hoyle, the Nobel Prize winner Hannes Alfven, and astronomers Geoffrey Burbidge and Halton Arp. [8] In 2004, a ‘Open Letter to the Scientific Community’ disputing the big bang theory was signed by 33 leading scientists has been published on the internet and in the science journal New Scientist. [9] The dissent letter has subsequently been signed by hundreds of individuals around the world. [10]

Creationist and Theistic Evolutionary Views

Young earth creationist scientists contest the Big Bang Theory stating that it is scientifically unsound. [11] [12][13][14][15]

Some Old Earth Creationists and Theistic Evolutionists argue that the Big Bang is in fact mentioned in the Bible. [16]
