Right...this will probably get moved to general, but I'm putting it here for now to try and spark an intellectual conversation with no lolcats. Also bear in mind that I generally struggle with physics as my mind will pick up something, then go off into a tangent. So I picked up Muse : The Second Law on Saturday and after listening to it a few times, I attempted to start reading up on the laws of thermal dynamics and various related bits. In short, I've got a couple of questions that are nagging me: - If energy cannot be created or destroyed, where did it come from in the first place. - When we have the 'eventual' heat death of the universe (i.e. max entropy), won't gravity as a force still exist, attracting the smallest bodies to each other, eventually converting entropy back to higher energy over the course of trillions of years.
