Any thoughts would be greatly appreciated,

Sabastien, it is called dark energy not dark matter just for clarification. Also, there is nothing wrong with your idea other than it is not observable. If there is an alternative that is observable or disprovable then your idea will always be just an idea. Maybe one day our technology or math models will allow us to definatively answer your question and "see" beyond our current "event horizon" if you will, but right now that is not the case.
