well, your collapsing universe theory is one of the possibilities of a big bang, the expanding universe is another... but, from the experiments that have taken place already, it appears that our universe is neither. if it were a collapsing universe, we'd see signs... if it were an expanding universe, all solar systems would be VERY far apart from each other and would continue to do so. our big bang led universe is stable... aka, not collapsing nor greatly expanding. it IS expanding, but at a rate that is constant, not exponentially like it would be in an expanding universe. there is an excellent book on the possibilities to why this is, called Faster Than the Speed of Light, it deals with VSL theory as an explanation of lots of current unsolved issues. its good, but be wary... it disagrees with the single most fundamental law of physics, a constant speed of light.
