Space.com: Two physicists in The Journal of Relativity and Gravitation ask can you discover the fundamental physical laws of the universe when the universe expands close to the speed of light? Future observers would only see an "endless black void," says co-author Lawrence Krauss, a physicist at Case Western Reserve University in Cleveland, Ohio, to space.com. Observers would only see a static--or non-expanding--cluster of local galaxies, nothing else. Without a cosmological frame of reference, Krauss explained, future observers will be clueless that their universe is still expanding. "It will be a sort of twisted situation, where thinking returns to what it was at the turn of the 20th century," he said. "The static universe," as the October journal article states, "will have returned with a vengeance."
