All right, all right, but apart from better sanitation and medicine and education and irrigation and public health and roads and a freshwater system and baths and public order, what have the Romans done for us?

but the Hubble Red Shift has been taken as a velocity/Doppler shift for so long, my re-explaining it as a distance shift has to be a more complete explanation than I've posted so far. Granted. Sometimes science evolves, sometimes new conjectures prove true. I still have to bear the burden of evidence, I know. I did however ask about contrary evidence and/or inconsistencies. I guess I'm on my own there. |

the em-shift as being caused primarily by the distance traveled by the light, not the relative velocity of the source to receptor, I would say only that I think the BBT is unsatisfactory from other points besides the point that the red-shift, CBMR, and neutrino background can be alternately explained. I would challenge the postulate that the conceptual expansion implies a reverse temporally small origin. Based on the perhaps arbitrary time periods, there's no guarantee that the Universe has been expanding regularly since the BB, with no contractive periods. |

1) What, according to your theory, is the frequency of that same emission line from the moving source that will be measured by the observer as it now appears, according to your theory? 2) Same assumptions and question, except with the source moving away from the spectroscope at 3000 m/s (0.00001 c) but at the same cosmologically negligible distance. 3) Same assumptions and question, except with the source moving away from the spectroscope at 300,000 m/s (0.001 c) but at the same cosmologically negligible distance. 4) Same assumptions and question, except with the source moving away from the spectroscope at 30,000,000 m/s (0.1 c) but at the same cosmologically negligible distance. 5) Same assumptions and question, except with the source moving away from the spectroscope at 150,000,000 m/s (0.5 c) but at the same cosmologically negligible distance.

Since the cosmological distance is given as negligible, the value of the frequency observed will differ from the original value by a multiplying factor related to the source speeds in each case. The formula is: f_observed = gamma * ( 1 - beta) * f_source = sqrt { (1 - beta ) / ( 1 + beta ) } * f_source where the lorentz scaling factor formulas are: beta = velocity / c gamma = 1 / sqrt( 1 - beta^2 ) c = 3.0 x 10 ^ 10 cm/sec Since lambda = 5000.0 A = 5.000 x 10 ^ -5 cm we have frequency = f_source = c / lambda = 6.0 x 10 ^ 14 hz In the five cases: 1) beta = 0.0000001 gamma = 1.00000000000001 f_observed = 1.00000000000001 * 0.9999999 * 6.0 x 10 ^ 14 hz = 5.9999994 x 10 ^ 14 hz 2) beta = 0.00001 gamma = 1.0000000001 f_observed = 1.0000000001 * 0.99999 * 6.0 x 10 ^ 14 hz = 5.99994 x 10 ^ 14 hz 3) beta = 0.001 gamma = 1.000001 f_observed = 1.000001 * 0.999 * 6.0 x 10 ^ 14 hz = 5.994 x 10 ^ 14 hz 4) beta = 0.1 gamma = 1.005 f_observed = 1.005 * 0.9 * 6.0 x 10 ^ 14 hz = 5.427 x 10 ^ 14 hz 5) beta = 0.5 gamma = 1.1547 f_observed = 1.1547 * 0.5 * 6.0 x 10 ^ 14 hz = 3.464 x 10 ^ 14 hz This shows a velocity-relativistc Doppler red shift for sources traveling away from us. It does NOT show that a red-shift is necessarily due to this cause (receding source). Last fiddled with by davar55 on 2013-03-18 at 19:28 |

Thank you for your response!
Right now, I can't remember how I had intended to proceed when I posted my questions. When my RW life is less hectic (I expect several RW problems to be resolved 3-5 weeks from now), I'll come back to review and regain my chain of thought (and _write notes to myself_ describing that chain so I don't lose it again!).

post so as to do some reviewing of relevant material. Also to work on improving my description of the theory of the em-shift and some other topics. I'm almost prepared to post a revised "attachment", and I wouldn't mind resolving some issues first, especially the em-(red/blue)-shift.
