" Finally, and inevitably, the flat universe will further flatten into a nothingness that mirrors its beginning. Not only will there be no cosmologists to look out on the universe, there will be nothing for them to see even if they could. Nothing at all. Not even atoms. Nothing. If you think that’s bleak and cheerless, too bad. Reality doesn’t owe us comfort. "

― Lawrence M. Krauss , A Universe from Nothing: Why There Is Something Rather Than Nothing
