Hi Im new to this & I havent got much time right now, but it always amazes me the way science is able to think up new models when new facts prove the old theories wrong. I dont mean that in a derogatory manner! Science works on a best fit model basis. If you look at the current standard model for physics on an universal scale at least then we have relavalistic mechanics, But before that we had newtonian mechanics. I think before that we had eucldian geometery. My point is this, as new phenomina are measured and quantified we replace the old models BUT THE NEW MODELS MUST exhibit similar behaviour to ALL the known phenomina in existance at that time. Not just the new Phenomina that caused the old model to be displaced. I'll state the obvious here because it only dawned on me a while ago so please forgive me but science does tend to use terms like "only possible explanation" but when Euclidian geometery was TopDog it clearly wasnt the only possible explanation as both newtonian and relatavistic mechanics also mimiced the behaviour of the world as the ancients understood it. Likewise when newtonian mechanics was king in victorian times relatavistic mechanics also mimiced the universe as the victorians understood it. So if you go back to the ancient greeks a second. There were at least 3 models mimiced the set of behaviours known to the ancient world. So it seems unclear how you can prove youve got the "only possible explanation" which I read about so often. It seems undeniable that the number of given models that will correctly mimic any set of phenomina is unknown. So when you read any article which claims this is the only explanation be wary , I dont think we have a way of calculating how many other possibilities there are so thats effectively a lie or a badge of incompetence. Of course you can setup ridiculously simple examples which may well only have 1 solution, but the universe is a wonderous and varied place so please no artificially simple scenarios. Occam's razor is a statement of faith not a law of physics and even it doesnt say the solution is simple. Just to pick the simplest of the candidates
