So I notice the "Big Science Questions" post and for the first time I really notice what the first question is:
• Why is there a Universe?
Let that sink in for a moment.
Read it again and note that it does not say 'How?', it says 'Why?'
Is this truly a questions for science to answer? To me it sounds more like a philosophical (or perhaps even religious) question. I understand the necessity of thinking big and not shying away from the big questions but we also have to work within the constraints of science. Big targets are wonderful but realism is neccessary as well. I am intrigued to know how we are expected to answer this question.
