I just saw this in New Scientist: http://space.newscientist.com/article/mg19626354.000-is-time-slowing-down.html "...we are fooled into thinking that the expansion of the universe is accelerating, because time itself is slowing down. " First let me say I'm an amateur so I'm just throwing out things that occur to me about this. I'm wondering if someone with more experience could shed some light on it. This brings to mind time dilation, speed of light, black holes, etc. Acceleration and gravitational fields also slow time. Is there any connection? Perhaps time dilation is not an effect but a cause. If you accelerate, your time slows....but what if it's the reverse and you actually accelerate because you are slowing your time? What if gravitational fields are created by slowing time instead of the reverse?
