Frontiers of astronomy Book

Quite technical but interesting beyond all the diagrams and characteristic curves. However I am left wondering how much is relevant to today's theories. Having just finished 'Quantum Theory cannot hurt you' I get the impression that the theories haven't moved on that much further, there is a view that matter that still spontaneously appear in a probabilistic sort of way.
There seems to be so many unknowns holding our current theories together that one feels in a hundred years time when scientists discover some universal law that will rationalise light, gravity, matter, magnetism, electricity and energy into one coherent theory our current understanding will seem like the medieval astronomers grappling with what revolves around what. But I digress. Hoyle writes well if only I could keep up with it all.
