Hi Clever People, I've been watching an amazing program about dark matter, dark energy and dark flow. I thought there were questions that should have been asked, but then I'm a website designer - what do I know! So... as an interested non-physicist, my apologies if this question is ridiculous... If Dark Energy is what is causing the 'empty' regions of deep space to expand / accelerate, could it be due to Dark Matter cooling down? Or heating up? Or perhaps even multiplying - like cell-division? I mean, if we're not quite sure what Dark Matter is except that it behaves totally differently from anything else, could it behave as above?
