SEARCH - First, note Serak's research into global rotation, or universal spin, as a cause of expansion and acceleration.<br /><br />Now, on question 2, which involves an edge to our universe, note this quote:<br /><br />Sciam, 3/05, p. 43 article on Big Bang<br /><br />“What does mark the edge of observable space? Here again<br />there has been confusion. If space were not expanding, the<br />most distant object we could see would now be about 14 billion<br />light-years away from us, the distance light could have<br />traveled in the 14 billion years since the big bang. But because<br />the universe is expanding, the space traversed by a photon<br />expands behind it during the voyage. Consequently, the current<br />distance to the most distant object we can see is about<br />three times farther, or 46 billion light-years.”<br /><br />So, yes, the edge of light and the edge of mass is indeed different.<br /><br />However, the above leaves open the possibility that the edge of mass may be larger in radius (in all directions) than the edge of light of our universe.<br /><br />Hence my theory that extremely distant mass may be causing acceleration of expansion from beyond our visibility horizon. <br /><br />In the latter scenario - way beyond!<br /><br />BTW - your post has some strange characters in place of accurate ones.<br /><br />Was that to illustrate loss of information due to random mutations?<br /><br />Do we have the equivalent of a DNA correction mechanism to restore the correct characters? <br /><br />[BTW - I have run out of time to research your above links, but I look forward to doing that soon - I have more time than usual because I caught the Flu{or something}. The beauty of the internet is that you can't spread viruses online!]
