Vic, I'd like to pick your brain a bit here. I always find it fascinating that one of our most successful theories, as far as predictive validity go, also leaves us stumped. Quantum mechanics makes absolutely no sense to us on an intuitive level. Given the recent developments in physics such as M theory, do you think we'll eventually hit a wall because no amount of experimentation can either confirm or falsify a theory?
Even in Einstein's time attempts were made to have a single set of equations (the unified field theory) which describes everything eg the strong nuclear force, the weak force, electomagnetism and gravity, the latter being the elusive
entity. This has not happened as yet. String theory was a
new attempt at that. Now, M theory is an attempt at unifying the 5 String theories.....it describes 11 dimensions in which gravity, or the particle associate with it, (graviton) is hidden. Because we mortals can only detect stuff in 4 dimensions (3 space dimensions+time) the graviton and the Higgs boson (the particle that is associated with mass) is undetectable with our current instrumentation. Are these all real...? Theoretical physics predicts that moments after the Big Bang the forces mentioned above separated from one another, together with the particles associated with each, into the multiple dimensions that M theory describes. Now how does one unlock all this ?
That's where the CERN experiments at the Large Hadron Collider (LHC) come in....here
high energy conditions, as at the moment of the Big Bang, is hoped to be created, revealing the particles such as the Higgs boson and the Graviton in our familiar dimensions, and thus can be detected. IF this succeeds the
reality of multiple dimensions (M theory) will be confirmed.
So to answer part of your question....we can detect and explain most things in our familiar dimensions...particles and other stuff which are not within these dimensions will remain undetectable, at least for the moment.
Quantum mechanics is a devil ?......here you only deal with probabilities......it's highly mathematical and mind boggling. However it has huge application in modern electronics and solid state physics...it's very real indeed.
