Falsification is a Myth: Aesthetics is King
The philosophical idea of Popperian falsification is a myth: an ideal that science does not and cannot (currently, if ever) live up to. For example, in discussions on the up-and-coming Electric Universe model orthodox-adherents will refuse to abandon the standard view until there is some piece of data that it absolutely CANNOT explain and which can ONLY be explained via the Electrical Universe model. As they aptly demonstrate, theories are as infinitely (indefinitely) flexible as the human mind that invents them. And by this logic we'd never have abandoned the Ptolemaic earth-centric model of the solar-system. No doubt one could invent all sorts of contraptions to account for ALL of our current data with this old model. Nobody would believe it through all the contortions, but it could be invented. There was no one piece of data that could not be explained by the old model, but which fit only the new one. Rather, as the model failed to predict event after event, it had to retrofit itself to new complexities which its infrastructure was not robust enough to deal with (analogies with software programming and "legacy code" are abound). These new ad hoc explanations kept piling on and on and people kept on believing in them long after they ceased to have any causal, reasonable or rational explanation. They just kept getting more and more absurd until the new model looked much more appealing next to this fantastic and growing Rube Goldberg machine of epicycles in deferents in epicycles.
In the end aesthetics is king. We like Copernicus because he UNIFIED and SIMPLIFIED our increasingly complex rational-empirical world-view. And this is precisely the advantage being experienced by the Electric Universe view. It gets rid of the mental clutter of ad hoc retro-fit after retrofit to constantly unexpected data, and unifies and simplifies them under one far more powerful force discovered after the foundations of the gravitocentric model were laid.
So, the shift is a gradient. Some folks are sensitive to slight changes in the force of simplification or parsimony and readily adopt the new, more aesthetically appealing and predictive model, while others are more conservative and cautious, preferring the safety that comes from large numbers of fellow believers in a "standard view".
What a beautiful image and thought experiment to resurrect these old models and fulfill their trajectory into infinite absurdity. If we could get a snapshot of them all compared side-by-side with one another, rising and falling one after the other: a series of curves beginning in unbelievable simplicity, peaking in the collective belief in robust predictive-explanatory power, and receding into indefinite complexity and absurdity as it fails to predict and explain more and more data, with the lag rates for retrofitting expanding further and further into the distance of limited returns...
Every theory? I don't know. Maybe we are approaching an asymptote....or maybe that's just another expression emanating from this infinite cycle.
