The name "Big Bang" was initially a pejorative coined by [[Fred Hoyle]] and used by other steady-state theorists to criticize the concept that the universe had a beginning. But the Big Bang Theory does not imply an explosion of matter into pre-existing space. Instead, the theory proposes that time began at that point and space expanded from then on, and more space is constantly created in the interstices between particles as the density of the universe falls. In other words, the Big Bang describes the expansion of space and time. Big Bang theorists state that the Hubble [[redshift]] is a consequence of this stretching of the fabric of space.
Observations of distant supernovae indicate that the Universe is actually undergoing accelerated expansion<ref>Riess, A. G., et al.

The Astrophysical Journal, Volume 517, Issue 2, pp. 565-586.</ref> and galaxy surveys<ref>[http://www.sdss.org/dr5/ Sloan Digital Sky Survey]</ref><ref>Tegmark, M., et al. Physical Review D, vol. 74, Issue 12.</ref> and recent observations of the microwave background<ref>[http://map.gsfc.nasa.gov/ Wilkinson Microwave Anisotropy Probe]</ref><ref>See, for example, http://arxiv.org/abs/astro-ph/0603449</ref> have allegedly corroborated these claims. [[Atheism|Atheists ]] claim that the acceleration is caused by something called '[[dark energy]]', for which there is only observational evidence but no experimental evidence. There is no viable naturalistic explanation of what dark energy is, which even a few atheists admit, yet they insist that dark energy is a naturalistic phenomenon.
Scientists refer to the theoretical exact moment the Big Bang supposedly began as t=0 ("t" standing for "time"). At this time, according to their theory all of the matter in the universe - in fact, the universe itself - was contained within a single point (a single point in mathematics is infinitesimally small). A burst of energy known as the Big Bang is claimed to have issued forth, and the universe began.<ref>http://www.umich.edu/~gs265/bigbang.htm</ref> 1.0×10<sup>-43</sup> seconds later, the force of gravity separated from the other forces.<ref>http://www.ccsf.edu/Departments/History_of_Time_and_Life/content/BigBang.htm</ref>
The universe appears to be [[Fine tuned universe | fine tuned]] for life to some contrary to more than 99.99...% of the universe having no life, suggesting that God set the laws of physics that allow the universe, complexity, and life to exist. Scientists have been baffled by these "coincidences" as they examine the parameters of the big bang and other physical constants.
Some creationists argue that the '''Big Bang theory''' is part of an effort to deny [[God's]] creation of all of existence. Christian physicists, such as Dr. John Hartnett,<ref>http://creation.com/starlight-and-time-a-further-breakthrough</ref> have claimed that the Big Bang theory was constructed to account for serious pitfalls to the [[theory of evolution]], particularly the needed timescale of billions of years, amply contradicted by terrestrial and astronomical evidence. Thus, the big bang is trotted out by [[atheist]] evolutionists to silence [[creationist]] opponents.
Young earth creationist scientists contest the Big Bang Theory stating that it is scientifically unsound.
