An Explanation from Nothing?
Here is David Albert’s review of Laurence Krauss’ A Universe from Nothing: Why There is Something rather than Nothing. Krauss claims that the laws of quantum mechanics can provide an answer to the old philosophical question of why there is something rather than nothing. Albert finds his answer, to put it mildly, wanting. There is no philosophical consensus about answers to this question or whether the question has an answer (or must have an answer) or whether it is even meaningful. There are two questions. Why is there Anything? Why does the universe have the particular feature it has (e.g. very low entropy condition 14 billion years ago)? The latter question was the subject of Eric’s recently posted paper and the ensuing discussion. An older philosophical discussion is Derek Parfit’s classic “Why Anything; Why This?” With some trepidation we would like to open a discussion of these issues again. Not only about Krauss and David’s review but also more generally about whether there could be a scientific or philosophcial answer to Why there is Anything? As usual the comments will be moderated for relevance. In thinking about these issues it might be helpful to listen to this.
