Gravity and Time
« on: 14/10/2008 14:11:08 »
I was thinking on this last night and something dawned on me. Perhaps it is something that has been in everyone else's minds all along, but... just in case.

It is telling that Einstein 'explains' gravity by referring to space-time. It struck me that gravity is the only force that we know of that is attractive only, and that  - while we're not sure why - time is, as we know it, one directional.

The dimension(s) of time, within space-time, it strikes me is fundamental to our understanding of gravity. Are the attractive only aspect of gravity, and the omni-direction of time a part of the same 'equation'?

I'm sorry that's not a very satisfying answer to a valid observation but I suspect it's the best you'll get atm.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!
