Here in the UK there is a short TV series on at present called 'The Theory of Everything' (8pm on Channel 4, Sunday nights). Last week they talked about Einstein and the Relativity Theory. It reminded me that Doc brought the subject up in his talks and spoke with reverence of the mathematics involved. I got the impression that he had worked through it himself and was trying to encourage us to do the same! I must admit I never got round to it. The programme is worth watching though.
However I am of the school that believes that it is impossible to "discover everything". How do you answer the question "why is there something rather than nothing" in a scientific way? You don't have to answer that question!!
