My hopes are slight for now, but I would really, really be amused if the whole house of cards came crashing down:
"Universe Is Most Likely Not Expanding"- New Research Claims
Current models of the Universe require dark energy to explain the observed rate of acceleration in the expansion of our Universe. Such measures are based off of measurements in the distance of supernova explosions in distant galaxies that appear to be farther apart than they should be if the acceleration of expansion were not taking place. This brings a question to light... if dark energy is not the explaining factor for such a phenomenon... then what is? What if our approach has been incorrect this whole time?
In the past year, the statistical significance of this signature cosmic acceleration has been a common idea subjected towards heated debate. Previous debates have pitted the standard Lambda Cold Dark Matter (ΛCDM) cosmology against a universe that is empty, whose expansion neither decelerates nor accelerates. Both models take on the simplified 100 year old cosmic expansion law-- Friedmann’s equation.
Friedmann’s equation assumes an expansion identical to that of a featureless “coup” of a universe that has no complicating structure. However, the present day Universe is actually one that contains within it a complex cosmic web of breathtaking galaxy clusters in sheets and filaments surrounding empty and vast voids.
David Wiltshire of the University of Canterbury in Christchurch New Zealand, the leader of the study said the following, potentially revolutionary words: “The past debate missed an essential point; if dark energy does not exist then a likely alternative is that the average expansion law does not follow Friedmann's equation."
Rather than comparing the ΛCDM cosmological model with an empty universe, this new study compares the fit of supernova data in the ΛCDM model to another model, Timescape cosmology. The model is devoid of all dark energy. Instead, clocks carried by observers in galaxies differ from the clock that best describes average expansion once the lumpiness of our Universal structure becomes significant. Figuring out an inferring acceleration is heavily dependent on the clock used.
Timescape cosmology turned out to be a slightly better fit to the supernova catalogue than ΛCDM cosmology. This reminds us of the words uttered during the OJ Simpson trial... “If it doesn’t fit then you must acquit.” However, not enough statistical data has been gathered in order to rule out one or the other and neither of the current evidence is strong enough to rule out one or the other either.
