The once trendy String Theory has begun to fray. Like Marxism, it's far beyond its use-by-date, yet somehow lingers stubbornly on in University Science Depts, that really should know better. The barmiest notion since post-modernism, it goes someting like this:
elementary particles such as electrons are not points [but] vibrations of one-dimensional strings 1/100 billion billionth the size of an atomic nucleus. Different vibrations.. produce all subatomic particles from quarks to gluons.. & strings exist in a space of 10 or 11 dimensionsNow, I'm no particle physicist, but 11 dimensions? Come on! The roar of nonsense alarm bells must be deafening! String Theory sounds like a cult. Mental abstraction eating itself; a hypothetical model that's become so convoluted and speculative that it now requires mystical, unprovable elements in order to prop it up. Strange, counter-intuitive ideas that can never be properly tested in the 'real world' - and thus satisfactorily proved or disproved - sound more like religion than science to me.
