No one really knows, there was a paper by Max Tegmark on HN yesterday with some new ideas and results, but I haven't had time to read it yet. http://arxiv.org/abs/1608.08225

The other responses to your question in this thread are as good I as could give you, but I would feel like I am recounting ideas that may be true but for which there is little evidence.
