Is the Big Bang the best cosmology? Are there other cosmologies that fit the evidence of what astronomers see in our universe? One article I read proposed the number of new cosmological models to be in the hundreds.
I think you will find that the Big Bang is a feature of many of those - perhaps most of them.
The Big Bang theory has truly become a case of the tail wagging the dog. The invention of dark energy and dark matter relies on human imagination. What has happened to observation shaping theory instead of the theory taking on a life of its own?
This seems very odd. In fact it is observations that are the driving force for these "inventions". And, as I understand it, neither is directly connected to the Big Bang as such. Dark Matter is proposed on the basis of the observed motion of objects in space, and Dark Energy on the acceleration in the expansion of the universe.
In addition, there is a suggestion that the “Cosmological Principle” may be incorrect, remember it states that the universe has no center or no edge. The Cosmological Principle was most appealing in that it provided a simpler solution in General Relativity but quantized redshifts and galaxy orientations seem to suggest a universe center. What could be more logical, if the universe had a beginning then it should have a center.
I'm pretty sure that Quantised Redshifts have turned out to be an artefact (and certainly it is not clear that it actually exists). And if space itself is expanding the idea of a centre is not so obvious since every point is a centre of expansion.
I would like to bring up a particular Christian cosmology “the Carmeli 5d cosmology”. It predicted the type 1A redshifts at the far reaches of the universe two years before they were discovered.
I hope that Cavediver or Son Goku will comment on this but I have to say that it looks rather questionable to me. Especially as there doesn't seem to be an adequate explanation of the alleged predictions. Also what drives the acceleration of the expansion if not dark energy ? The one-way light travel time looks especially dubious with it's unexplained "proportionality constant" (and what observations justify it ?)
