But what if light loses energy over extremely long distances, as has been proposed by certain physicists? If this is so, then there is no expanding universe and turntables remain as they were created. In fact the Lencos support this theory, since apart from re-lubing there seems no appreciable decay with time, given a reasonable amount of care over the years: certainly, no Lenco which has passed through my hands has shown any significant signs of decay apart from cosmetic. The extremely stable speed even after more than 30 years of use puts to rest the expanding universe theory ;-). As to the curvature of space, since these 'tables were created in curved space in the first place and so are curved from the moment of creation, I don't see how time would increase the relative curvature of any mechanisms created within it, perhaps I'm missing something. I know my spine seems to be curving with age.
The effect of the Expanding Universe on turntables
Since the Universe has been continually expanding after the Big Bang, then it stands to reason that all objects have expanded also , but not nessecarily in proper proportion. This means that the turntable you buy today will actually be larger(and contain more mass) at some date in the distant future (20 years?). I have now discovered why I have never had a used turntable (over 100 turntables) that is on accurate 33&1/3 RPM speed, even with quality synchronous motors. This phono-nomenon can only be attributed to the fact that all the motor parts and the platter are now larger and more massive than previously and thus the ratios of pullies and gears is no longer as designed (in the past), this is the only explanation I can offer as to why the speed of old turntables is faster than when new(by a small percent).It also explains why many older mechanical devices never work properly , no matter how well maintaied and repaired.
