Both are interesting fields, but the problem in modern times seems to be that so many paranormal scientists, physicists and theologists are all trying to make a name for themselves that the theories being produced and published are so far beyond anything that we could possibly experiment and validate that none of it is really relevant.
Loads of people have come up with theories to "guess" at how physics, the universe, God, ghosts, etc. exist and work. In the distant future, some of these might be proven correct, but for now, it's just guesswork. That's why they're called "theories"!
I mean, they still can't even explain how light works!
Personally I like more immediate feedback. The "Exceptionally Simple Theory About Everything" that some surfer/physicist came up with in November is more up my street, 'cos it's liable to be strengthend or even disproved when the CERN Hadron Collider comes on line later this year (provided they don't create a black hole and destroy everything, of course!).
I also like the idea of a unification theory anyway. If everything is built up of the same tiny little sub-atomic particles, why shouldn't a single theory explain how everything works?
