of Thermodynamics tells us that the universe had a beginning (when the disorder was zero) so that disproves the Steady State theory.
The Big Bang Theory
Firstly, the Theory
The Big Bang theory is the current scientific explanation for how the universe came into being. According to the theory an extremely dense and hot ball of matter, very small in diameter, exploded, creating hydrogen and helium and providing the basis for further evolution of matter. This has to be sufficient matter to make billions of galaxies each containing hundreds of billions of stars.In theory, as the new matter expanded, it created space. It is thought that the Big Bang occurred about 10 to 20 billion years ago and that the universe has since been expanding and cooling.
The most popular scientific view is that there was a singularity at first – something where the laws of physics break down. At the proposed start of the universe with a singularity the density of the universe and the curvature of space-time would have been infinite. Because all the known laws of physics break down under these conditions this is a serious problem for science. Science is therefore unable to describe or predict the initial conditions and how the universe began. It is fair to say at the outset that The Big Bang Theory does not rule out God because no one has been able to say what happened in the first small fraction of a second.
The Evidence given for the Big Bang – an expanding universe
For the Big Bang to be correct, the universe must be expanding outwards from the centre of the blast.
Evidence for this expansion is given in the form of
