superluminal recession vs gravitational propagation speed

[R1]

it appears that stuff beyond the observalbe universe is receding<br />superluminally. <br /><br />If I told you speeds above C are possible and really did occur,<br /><br />is it becoming safer to think that gravitational propagation speed limits<br />are not so constant either? <br />this seems crazy, but let's say that scientist #1 is outside our observable universe<br /><br />now, since he is travelling faster than the speed of light away from us,<br />didn't his planet and sun, etc, take their respective gravity wells with them?<br /><br />(So then theres no gravity whatsoever yet in the dark regions 'ahead' of their direction of travel?<br /> is this a way to approach a black hole without falling into it ?<br /><br />did the stuff outside the observable universe leave a trail of light and<br />gravity that is trying to catch up to them and is potentially still here<br />I mean in our local reality in our observable universe? <br /><br /><br /> <div class="Discussion_UserSignature"> </div>

what if I told you stuff inside the observable universe is receeding at superluminal speeds due to the hubble flow?<br /><br />Put in "Big Bang Misconceptions" into google, the first link should be a scientific american article outlining it.<br /><br />the bit that pertains to this thread is: http://www.sciam.com/article.cfm?articleID=0009F0CA-C523-1213-852383414B7F0147&pageNumber=3&catID=2<br /><br />I really need to remember how to condense those using ubb code.
