Curvature Cosmology: new edition
Hi
Curvature-cosmology is a complete cosmology that is presented as an alternative to the Big-Bang model. Scientifically it is a much better theory as listed below. A draft version of the second edition of Curvature Cosmology. is freely available from my website http://www.davidcrawford.bigpondhosting.com It is a pdf file 161 pages and 1.18 Mbytes: It contains two papers and referee's comments "Type 1a supernovae agree with a static universe" arXiv:0901.4169 "No Evidence of Time Dilation in Gamma-Ray Burst Data" arXiv:0901.4172 It is elegant and mathematically much simpler. It is refutable. It obeys the perfect cosmological principle of being uniform in both space and time. It is additional to general relativity and quantum mechanics and does not require any changes to either theory. For homogeneous plasma, it has one free parameter - the density. Hubble's constant is determined by the density. Predicted: H = 64 km.s^-1Mpc^-1,Observed: H = 63.1 km.s^-1Mpc^-1 It predicts an accurate value for the temperature of the X-ray background radiation. Predicted: 2.56x10^9 K, Observed: (2.62±0.04)x10^9 K. It predicts an accurate value for the temperature of the microwave background radiation. Predicted 2.18 K (up to 2.74 K with more heavier elements), Observed 2.725 K. Analysis of Gamma-Ray Burst and supernovae data provides strong evidence that the universe is not expanding. There is excellent agreement with many cosmological observations without the need to invoke ad hoc additional hypotheses such as evolution and dark matter. It can explain many minor observations such as the K-effect for bright stars. It accurately predicts the observed rate for the solar neutrino flux. It can explain the Pioneer 10 anomalous acceleration. Laboratory tests of curvature-redshift are possible. I believe that one of the major reasons why I cannot get astronomers to seriously consider my theory of "Curvature Cosmology" is that it requires a major paradigm shift. Often they compare a measurement that they are familiar with from their own work with my result and see that there is poor agreement. This arises because although the raw measurements may be identical the processing of those measurements either explicitly or implicitly involves the use of a cosmological model. A trivial example of this is the determination of Hubble's constant from Cepheid variables (Freedman et al 2000, ApJ, 553, 47). A simple analysis of 23 distances and velocities (I have omitted NGC3031 since it seems anomalous) provides a ratio of 94 km/s/Mpc. However in curvature cosmology the universe is static and the redshift is proportional to the integral of the square root of the density of the medium along the light path. Thus there will be a contribution to the "velocity" from the halo of our galaxy and any halo in the host galaxy. A crude method to eliminate this is to fit for a constant offset as well as the Hubble ratio. The result for the same data is H = 74 km/s/Mpc with an offset of 47 km/s. Since the effect of the halo and other inhomogeneties in the medium will seriously change the local flow model and this result. Thus in a simple situation where although the distances are small the assumed cosmological model can have a significant effect. (Note that the values provided are purely there to illustrate the effect of a paradigm shift and not to be used as actual estimates of H). Regards David F. Crawford |

Smith =================================== I like the advertising bullets he writes: It is elegant and mathematically much simpler. Washes whiter. It is refutable. Colours stay fast. It obeys the perfect cosmological principle of being uniform in both space and time. Cleaner fuel, cleaner engine, less air pollution. Reduces your carbon footprint. It is additional to general relativity and quantum mechanics and does not require any changes to either theory. Donate to prostrate cancer awareness. (I really love that one. They want to me to pay for their advertising so that they can make me aware.) |
