The Big Bang theory implies that there was a point in space where all things came into existence through a colossal explosion and then all mater is expanding from this original point outwards. That point would be easy to locate if the "expansion" of the Universe would be consistent as a result of an initial explosion. That originating point has never been located. Why? Because there is no such a point. The Universe came into existence as is today and the illusion of expansion is nothing more than ordinary movement of colossal masses of mater in an orderly manner. There are galaxies and clusters that are moving away from us, there are galaxies and clusters that are moving towards us, there are galaxies and clusters that move along with us. The Universe cannot be expanding because the Universe occupies the whole infinite space, and if it were expanding, it would imply that there is still additional space where it could expand. If the Universe is not infinite, then it must have an edge. What is there beyond that edge? The theory collapses on itself.
