The Big Bang Theory is the name given to the concept that the Universe came into existence in an enormous ‘explosion’, in which spacetime itself was created. This theory was arrived at following the observation by Edwin Hubble that the Universe is expanding, with galaxies receding away from us in every direction in space. Extrapolating this expansion backwards in time naturally leads to the conclusion that the Universe started out as a point of infinite density, at some finite time in the distant past.
