Apololgies in advance for my complete lack of understanding of what are probably a well established facts but I have a few questions which have been buzzing around in my head (a rather empty head at that). Why is the speed of light finite? Why can't it go faster? Is there an accelleration associated with light or does it just travel at a constant speed? The reason I ask is that I have read that space can travel faster than light and that during the Inflation Period the Universe expanded very rapidly many times the speed of light. Expansion then continued at a slower and consistance rate until about 5 billion years ago when the expansion started to accerate and is continuing to accerate even today. The main reason given is that as the universe expanded it became less dense and allowed the 'dark force' to overcome the effects of gravity and so allow for accerated expansion. My suggestion is that space has a natural tendancy to expand, in much the same way that light will radiate from a source, and does not require a 'dark force' to make this happen. What we see as a 'dark force' pushing the universe apart, is just space expanding with matter being carried along with the space. This idea does raise a few question about how space, assuming that it does not require energy to expand (or very little), is then able to move matter, which requires a lot of energy (a awful lot of energy). I have no idea how matter and space are able to interact and even why matter should be carried by space. I would be gratful if any geniuses out there have the answers, or can completely shoot me down in flames for such a ridiculous idea.
