Re "It's not likely this will replace the Big Bang Theory any time soon.":
There are a fair few theories contending with the BB. The BB idea was originally suggested because of the red-shift in light from distant stars. Longer wavelengths = stars travelling away from us. What if the geometry of space-time is causing the light to *appear* shifted? (The "Vorticitating Hypersphere" hypothesis.) Then there's no expansion at all. Bang goes the theory! Chaos magician Peter J. Carroll: "Years ago I led a group of 30 mostly German magicians in an attempt to send a servitor probe back to the big bang era. It then reported to us what it saw in our dreams later that night. At the time we all accepted the big bang interpretation of cosmological data. Astonishingly nearly everyone reported that his or her dreams depicted the universe as looking more or less the same then as it does now. I have spent the intervening years developing the math and interpretations to explain this result. It seems that if the universe consists of a vorticitating hypersphere then it may verify our findings. Perhaps we will see confirmation within a decade."
