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.  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.

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^-43 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>
