given that the Universe is our entire time and space bubble, and that there is NO space or time beyond its extents then I'd think Leovinus is correct. If we went beyond its current extents, then the gravitational attractions between yourself and the Universe would be stretched and therefore you'd remain connected. You'd have to go far enough away from the universe that'd you'd two distinct bubbles of "time and space" would be created, one for yourself, and the other for the universe. <br /><br />I think the current theory is that you'd just warp around to the other side of the universe. The reason light isn't "everywhere" because of it going around in endless loops is because the extents are farther away than light has yet been able to travel, due to the age of the universe being too young.
