Hi. I would like to discuss this: http://www.sciencedaily.com/releases/2007/05/070524094126.htm "Now, physicists Lawrence Krauss from Case Western Reserve University and Robert J. Scherrer from Vanderbilt University predict that trillions of years into the future, the information that currently allows us to understand how the universe expands will have disappeared over the visible horizon. What remains will be "an island universe" made from the Milky Way and its nearby galactic Local Group neighbors in an overwhelmingly dark void. "We may feel smug in that we can detect a host of things future civilizations will not know about, but by the same token, this suggests we wonder about what important aspects of the universe we ourselves may be missing. Thus, our results suggest a kind of a 'cosmic humility'". I couldn't find the artice they wrote online. I guess I have to wait until it is published. anyone have access to it? Is this conclusion a surprise to anyone? I mean 3 trillion years from now, the CMB will be redshifted to the point that it is past no longer within our Hubble Sphere? Does this treatment assume our universe is not closed?
