First of all, despite my choice of title I have some understanding of it (or atleast acceptance of it's laws and effects), what trips me up is my mind asks what the various implications of our current understanding of gravity are (bad mind, sit, lie down) and I realize that my and our understanding of gravity are not one and the same, in that my understanding is anecdotal and basic. I usually can't get to grips with a concept at all unless 1 of the following statements are true. I have some grasp of the concepts that underpin a concept. I believe (in error) that I have grasped of the concepts that underpin a concept. As a result, you might imagine that my 'understanding' of physics is full of bloody great big gaping holes, around which I must reconcile specific laws/phenomena. I find that to make any progress I must work backwards, filling in the blanks and correcting bad assumptions if I am to make progress in accepting new information. Ok, so in that spirit I find myself trying to get my head around a few questions concerning gravity, I am probably not alone in that particular endeavour. The question that is really tripping me up which I expect is something that is very clear to the initiated is the following. Does a body of mass exert a force of gravity on other masses, or is the it the case that space, being warped by the presence of a massive object, itself is exerting the force. That is to say, that 2 bodies of mass in space (lets call em planets because why not) do not directly influence eachother, but do so indirectly due to the warping of space. There may not even be a distinction between the two statements. My second question is this, is there such a thing as an absolute position in space relative to... space? It sounds intuitive enough to say yes, but now and then I read or hear statements to the contrary or atleast to say that the question is inherently meaningless. I accept what I know of relativity as a given, but there is so much I have not understood ie the speed of light as a 'speed limit' I imagine to mean speed relative to absolute space, but again I am often having cause to question my interpretation. At this point I will leave it at that, the more I write the more I confuse myself and this post has the potential to end up being an indecipherable mess of words, halfway down I had to struggle to remember what it was I actually wanted to ask. I will close by saying this, I accept the possibility that some of my questions may border on the philosophical, but I am hoping that science has a clear stance on them. Thanks, and apologies for the wordcount it would seem I enjoy hearing myself type!
