why do people feel the need to buy expensive cable

I think this guy gets it right:

"[Nature] ... never says "Yes" to a theory. In the most favorable cases it says "Maybe," and in the great majority of cases simply "No." If an experiment agrees with a theory it means for the latter "Maybe," and if it does not agree it means "No." Probably every theory will someday experience its "No"—most theories, soon after conception."

                                                       Albert Einstein

The quote is in an article in Forbes titled "Scientific Proof Is a Myth". The main premise of the article is that "nothing in science can ever truly be proven. It's always subject to revision."

Interesting article that is pertinent to the cable debate, IMO.

OK, boys and girls, what time is it? It’s time for a little, What the heck is happening to science these days? Taken from Zen and the Art of Debunkery. Enjoy. Italics provided by your humble scribe.

Seeing with humility, curiosity and fresh eyes was once the main point of science. But today it is often a different story. As the scientific enterprise has been bent toward exploitation, institutionalization, hyperspecialization and new orthodoxy, it has increasingly preoccupied itself with disconnected facts in a psychological, social and ecological vacuum. So disconnected has official science become from the greater scheme of things, that it tends to deny or disregard entire domains of reality and to satisfy itself with reducing all of life and consciousness to a dead physics.

As the millennium turns, science seems in many ways to be treading the weary path of the religions it presumed to replace. Where free, dispassionate inquiry once reigned, emotions now run high in the defense of a fundamentalized "scientific truth." As anomalies mount up beneath a sea of denial, defenders of the Faith and the Kingdom cling with increasing self-righteousness to the hull of a sinking paradigm. Faced with provocative evidence of things undreamt of in their philosophy, many otherwise mature scientists revert to a kind of skeptical infantilism characterized by blind faith in the absoluteness of the familiar. Small wonder, then, that so many promising fields of inquiry remain shrouded in superstition, ignorance, denial, disinformation, taboo . . . and debunkery.

"[Nature] ... never says "Yes" to a theory. In the most favorable cases it says "Maybe," and in the great majority of cases simply "No." If an experiment agrees with a theory it means for the latter "Maybe," and if it does not agree it means "No." Probably every theory will someday experience its "No"—most theories, soon after conception."

>>>>As fate would have it in this hobby when a test proves negative it actually doesn’t mean “No.” It means “Maybe” because maybe the test was flawed and we’ll have to have someone else take a crack at it. And if the results are positive it probably means YES to the theory, though prudence dictates we get some more postive results on board for good measure. Any test is only one data point. Apologies to Albert.

Actually there are many things in Science that are not (rpt not) subject to revision. The absolute constant of the speed of light in a vacuum, the mass of an electron, all elements have exactly the same composition everywhere in the universe, the universe is expanding forever, the physical characteristics of a black hole have been known with absolute certainty since the 1960s, the hypotenuse of a right triangle given the other two sides is never in doubt, the equivalence of energy and mass (E= Mc2), all electromagnetic waves are comprised of photons, and all manufactured wire is directional.
