We live at a very special time . . . the only time when we can observationally verify that we live at a very special time!
Lawrence M. KraussAs a scientist, I don't believe anything. Science shouldn't use the word belief. There are things more likely and less likely. Science can say nothing with absolute certainty.
Lawrence M. KraussThe fact is that people would rather cling when they're afraid of something to a priori beliefs than rather open their minds about it.
Lawrence M. KraussScience has been effective at furthering our understanding of nature because the scientific ethos is based on three key principles: (1) follow the evidence wherever it leads; (2) if one has a theory, one needs to be willing to try to prove it wrong as much as one tries to prove that it is right; (3) the ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.
