Below I respond to an inquiry about the cosmological model presented in my book and Carmeli’s Cosmological Relativity theory. I used Carmeli’s cosmology to create a biblical creationist model for the origin of the Universe, with a timeline which includes the 6 days of Genesis creation beginning about 6000 years ago. I took parts of Carmeli’s big bang cosmology and added biblically based hypotheses (and speculations) to make it conform to Scripture.
That means it is no longer Carmeli’s cosmology but a sort of hybrid cosmology. Carmeli only constructed a 4 dimensional (4D) space-velocity model for the Universe. He never found a full 5D model for the whole Universe which might be used to construct a history close to the creation epoch. I theorised on a new model–call it the Carmeli-Hartnett model if you like–which is 5D. I added the time dimension to Carmeli’s space and velocity dimensions, to create a linearised 5 dimensional model. That is shown in Appendix 6 of my book “Starlight Time and New Physics“. I then used that, making additional assumptions, to explore the idea of rapid time-dilation during Creation.
I do not claim it is the answer to the creationist starlight-travel time problem. If God did something like I describe it could provide us with an understanding of it. Adding new physics may be a simple way to avoid many fudge factors in cosmology but it does mean adding a new dimension that is very hard to even conceptualise.
