Hi, I'm new to the forum, and didn't really know where else to ask some questions, and get good answers, I'm fairly poor at mathematics, and grammar, but I have a passion for physics, astrophysics and cosmology. I have some niggling ideas and hypothesis that I can't find answers for, and I hope I don't make myself look foolish, but Einstein said he "visualised" his ideas, and I had a... "visualisation", that the expansion of space, is somehow linked to "arrow of time", in the sense of one way direction of time in large scale, could it be directly linked to expansion? And could it be linked to time dilation? Or does mass have any effect on expansion? I'd appreciate any response, and please correct any mistakes I've made.
