Natural Science Forum / Physics / Relativity / November 2006the empirical in twin paradox
Dear Sirs I have difficulties to see the empiricals in twin paradox, but only can see subjective evaluations, please show me the empiricals, not the arithmetics Adj. 1. empirical - derived from experiment and observation rather than theory; "an empirical basis for an ethical theory"; "empirical laws"; "empirical data"; "an empirical treatment of a disease about which little is known" empiric theoretic, theoretical - concerned primarily with theories or hypotheses rather than practical considerations; "theoretical science" Dear tn: > Dear Sirs > > I have difficulties to see the empiricals in twin paradox, but > only can see subjective evaluations, > > please show me the empiricals, not the arithmetics I suppose you mean "experimental support"? - half-life of muons is velocity dependent - magnetism requires it, if charge and motion are the only things responsible. - http://www.physics.adelaide.edu.au/~dkoks/Faq/Relativity/SR/experiments.html#5.% 20Twin%20paradox David A. Smith > Dear tn: > [quoted text clipped - 13 lines] > > David A. Smith Dear Sir Smith I asked you Sirs about the specifc empirical observation, but the link you gave me only enlists experiments and subjective evaluations None of the experiments express clearly empirical and explicit that the time was dilated, but that at the end of the experiments some materialized anomalies seems to had happen Please try again Dear tn: > > Dear tn: > > [quoted text clipped - 21 lines] > > Please try again <QUOTE> A central concept in science and the scientific method is that all evidence must be empirical, or empirically based, that is, dependent on evidence or consequences that are observable by the senses. <END QUOTE> There are empirical results. The "anomalies" exist without impressing subjective evaluations on them. Perhaps you meant a different word, or a different paradox? You do realize that the twin paradox derives from "subjective evaluation", right? So there is no problem, until you assume / impress some physical model connecting *nows*... for objects / people with or without regard to their "histories". Can you define "right foot" or "left foot" if your species only *ever* has one? David A.

Perhaps you meant a different word, or > a different paradox? how can it be empirical when none of the observers are sensing by sensors a dilated time, but contrarry, all their sensors are sensing empirical undilated time, anywhere and anytime? > You do realize that the twin paradox derives from "subjective > evaluation", right?

In the case of muons, it is the number of muons present at a given altitiude. >> There are empirical results. The "anomalies" exist >> without impressing subjective evaluations on them. [quoted text clipped - 5 lines] > all their sensors are sensing empirical undilated > time, anywhere and anytime? The population of (for example) muons does not indicate the expected decay rate. More of them survive to lower altitudes than should be able to. The sensor senses *elapsed time*, and does it in the frame of the muons at some average speed. Which speed can be separately measured. >> You do realize that the twin paradox derives from >> "subjective evaluation", right?

The paradox isn't in the data, but in the "common sense" impressed ahead of time into the situation. A paradox requires a pair 'a things... ;>) David A.
