Interesting papers, relatively recent, quite readable, by the same person (Southampton University), and using SN1A data (see attachments, if interested):
"Alternative cosmology fits supernovae redshifts with no dark energy" - March 2009.
His conclusion:
"Supernovae and radio galaxy redshift data are fitted in an alternative cosmology. The galaxies are assumed to recede with unchanging velocities in a static Robertson-Walker metric with a(t) = 1. An exact fit is obtained with no adjustable parameters. There is no indication that the recession velocities are changing with time, so no call for ”dark energy”."
Second paper:
"Does gravity operate between galaxies? Observational evidence re-examined" - May 2010.
His conclusion:
"On the largest scale, the net force accelerating or decelerating the galaxies is apparently zero. Each recedes with unchanging velocity following Newton’s first law."
Please note I'm not trying to push any particular personal views or opinions here (there's always more scientific debate for and against - and it seems this one isn't fully settled), but I thought it was interesting because the conclusion seems to differ from other papers based on Supernova Type 1a data.
In his words:
"This model may be incompatible with other cosmological data, such as the cosmic microwave back-ground and the distribution of galaxies. Most phenomena, however, depend on the distribution and movement of matter, not on the expansion of space itself. These questions remain to be examined."
Interesting.
Cheers.
PS: He's also saying that Martin Rees' (& others) provided comments during the study.
