Dark Energy AlternativePhysical Cosmology

Recent research by Christos Tsagas, a cosmologist at Aristotle University of Thessaloniki in Greece, has argued that it's likely that the accelerated expansion of the universe is an illusion caused by the relative motion of us to the rest of the universe. The peer reviewed journal entry cites data showing that the 2.5 billion ly wide region of space we are inside of is moving very quickly relative to everything around it. If his theory is confirmed, then dark energy would not exist (but the "dark flow" still might). His research can be found in the journal, Physical Review

"But this apparent speed of recession is not real; it results from numerous factors of error embracing angles of observation and other time-space distortions."
It's rare for the authors to point to a specific scientific assumption, and state that it is wrong. Even rarer that they should hint about why. My guess is that without a little help, our cosmology would head increasingly off course. (This might be why they also chose to say so much about ultimatons.) In this context it was fun to see a 2010 BBC documentary showing the entire college of cosmological researchers at the Perimeter Institute laugh at the old fashioned idea of a "Big Bang" universe. These guys will be writing the next set of text books about such things.
More interesting is Tsagas' work on gravito-magnetic effects: think of the mass of Paradise ringed by rotating ellipses of compact mass. If Chistos Tsagas should run the numbers for this, and plot the gravito-magnetic harmonics playing across pervaded space, I think he might come up with a theory about nested space levels, variable time, ...
great days to be in the cosmology business,
