Space and time could not expand from one single place, could they? If you take a balloon, and expand it, all points on the balloon will move away from each other. Scientists use this to explain the expansion fo our universe. But the balloon model is for a 2d universe right? i.e the surface of the balloon. In a 3d universe, the "center of the balloon" would be all places at once, to infinity....
Sound logic? I dont understand why nobody has ever pointed this out. Please don't mind the arrogance...

In physical cosmology, the Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The theory is based on the observations indicating the expansion of space in accord with the Robertson-Walker model of general relativity, as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity.The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the universe (Hubble's law) began-calculated to be 13.7 billion (1.37 × 1010) years ago (±2%) -and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory.From this model, George Gamow was able to predict in 1948 the existence of cosmic microwave background radiation (CMB).The CMB was discovered in 1964[3] and corroborated the Big Bang theory, giving it more credence over its chief rival, the steady state theory.This might help a little

Difficult question. I can't claim to know the answer, but I have thought about it...I think the question itself is where the trouble starts. It's kind of like asking, "Where in space is all space?" To think of what's on the other side of space or what happened before time is an impossible endeavor. Any analogy for the universe will obviously be insufficient. I recommend A Brief History of Time or A Briefer History of Time...They break these concepts down to their most basic levels...

you should read Brian Green's The FAbric of the Cosmos: Space, Time and the Texture of REality...all will be explained grasshopper
