I hope that every [person] at one point in their life has the opportunity to have something that is at the heart of their being, something so central to their being that if they lose it they won't feel they're human anymore, to be proved wrong because that's the liberation that science provides. The realization that to assume the truth, to assume the answer before you ask the questions leads you nowhere.
Lawrence M. KraussWe should provide the meaning of the universe in the meaning of our own lives. So I think science doesn't necessarily have to get in the way of kind of spiritual fulfillment.
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.
Lawrence M. KraussMetaphysical speculation is independent of the physical validity of the Big Bang itself and is irrelevant to our understanding of it.
