Life is a temporary, cosmic accident and the universe may very well be meaningless. That's depressing — or is it?
The universe doesn't care about you, and the future is miserable. So begins theoretical physicist Lawrence Krauss' guide to optimism. Optimism? You heard us right. We may never find meaning or purpose in the universe, but to assume that our purpose is interlinked with that of the universe is what Krauss calls the height of solipsism. Life is beautiful precisely because it's so temporary, and if anything helps us to be optimistic in a morally neutral universe, it's science. Asking questions and understanding what something is helps us realize the consequences of our actions. Armed with knowledge, we can make decisions for the common good. If that's not hope, what is?
