What I asked about considering our 'visualization' of "a" reality-percept as provisional - to work with, until a better one shows up : > >>When did you last learn that the tenets of ongoing > >>physics are only "provisionally" accepted as 'real'? and mentioned the BB as a (side?) example. BTW - speaking about 'the' Big Bang: Hubble (1922) detected a redshift in the spectra of distant (and greater in even more distant) heavenly bodies and was ingenious enough to connotate this with the Doppler effect, concluding, that this shift into lower frequencies of distant bodies MAY HAVE BEEN the result of a receding movement of the light-source, similar to the 'lowering voice' in a Doppler - type auditive phenomenon. Consequently: the universe MAY expand, producing those (alleged) receding movements from us. This is the 'provisionally(!)' accepted reality-percept as of the early 1920s: The idea was logical. - "IF" - this is a fact, we may apply a retrograde line backwards and arrive to the zero-point, when the universe was started - gradually collapsing into an extensionless point - from which it erose "in a big bang". Then came the first (and biggest) mistake: "scientists" took our present physical science circumstances and applied them (equationally) to all those changing systems of concentration with incomparably higher density of everything (energy? temperature? gravity? if someone ha an idea what these are). They assigned the fractions of the hypothetical 1st sec (^-40 etc.) to storytelling of features just "freezing out". It still did not make sense with our equations derived in the present 'cool' and dilated physical system, so an inflation was invented to correct 'some' of the compressed state which made the equations fully paradoxical. IF the Hubble proposal is right (and I give credit to assume it) the calculations and their conclusions must be false - e.g. the age of the universe. A linear retro-math for a chaotic development cannot match, unknown intermittent events are all neglected, the relationships of THIS system are applied for a totally different one. No experimental proof, not even asymptotically: those many orders of magn. make speculation into science fiction. (This is why I composed my narrative). After that - sorry, Brent - not those, who wanted to deny the theory, rather those, who wanted to show 'experimental' simulations assignable to the 'truth' of the theory - designed and performed thousands and thousands of experiments all slanted towards 'evidencing' the idea (E.g. Wilson's background radiation, presented as the 'remnant' of the Big Bang energy-level - earning him a Nobel). So the 'proving' became the way to grants, tenure, acceptance into the science establishment. Finding evidence against it? In who's acceptance? Disproving it? Dare swim against the flood? Become a scientific leper? The shift in light-frequency can be altered in several other ways, but attempts to even mentioning such (e.g. compartmentalized universe, gravitational fields changes) were rejected before any serious consideration as 'hoax' (sic). (I have a personal experience to that by a prestigious New England professor). Expanding Universe with Big Bang Startup is the bible in conventional science. "Not one experiment to counter-evidence it!" also: "Not one penny to spend". ...And of course there is Fred Hoyle's harmonic theory with no beginning, etc. So the (provisional?) reality-percept stays and generation after generation it gains more and more 'belief' as a real-reality-view. * This is a recent example, with a knowledge-base close to our present level of the cognitive inventory in our epistemological enrichment. I did not go further back into eras with much less information about the world and much more speculation "how it COULD be", like e.g. 2500 years ago and way before that. That old ape must have been a genius to start thinking!
