    Linearly-expanding FRW model matches DL-z observations

    Thank you for the reference. Very interesting. Basically, they are saying that linear coasting can fit CMB data provided it is interpreted in the appropriate framework. Basically they are on the same line as BL&C, only that BL&C give a physical basis on why linear coasting is valid. In fact...

    Linearly-expanding FRW model matches DL-z observations

    I initially did it based on measurements that Ho to = 1, and to see what happens. I came to the DL-z formula that matches SN-Ia observations. Later on I found the BL&C paper, which follows a sounder path. If there are galaxy clusters/superclusters of matter, and clusters/superclusters of...

    Linearly-expanding FRW model matches DL-z observations

    This replaces my early post about "variable G" (no such thing). My point was (and is): setting the Hubble constant H(t) = 1 /t by ansatz, thus matching current observations that H(to) to = 1, has the consequence that the scale factor varies linearly with t. a(t) = a(to) (t / to) The...

    Time dilation in de Sitter Special Relativity

    Since in the papers by Guo & Huang and Aldrovandi & Pereira I couldn't find a practical formula for time dilation in de Sitter Special Relativity, I wonder if anyone here has it (or can derive it from the high-level formulas in those papers). Specifically, let be a de Sitter spacetime with...

    Inconsistency in Concordance Model?

    You're right. However, I think I can mention one obvious inconsistency in the FRW metric that I overcome in my model. In FRW matter has constant mass and constant equivalent energy m c^2 (c is constant), while photons have decreasing energy (h c / lambda) and decreasing equivalent mass (h /...

    Inconsistency in Concordance Model?

    Hola Juan. What a coincidence I've just finished developing a new cosmo model which agrees with the DeLightS model in your 2003 and 2004 papers. In fact, I mention both papers right in the abstract! See http://cifresmodel.blogspot.com/ There is a last item needed to finish it, and if...
