I gave the first presentation of the Universe 4.0 model at the inaugural South Coast Cosmology Meeting, hosted by the University of Sussex. To say that it didn’t go down too well would be something of an understatement. Leaving aside the fact that I was trying to cram far too many new concepts into a 15 minute speaking slot, the nature of this topic was not really a good fit with the aims of the meeting, which, I believe, was to give PhD students the chance to share their current research with colleagues from other institutions.
However, the main surprise from my point of view was the fact that about 2/3 of those present at the meeting were broadly happy with the existing Lambd-CDM model. I don’t think my brief review of the problems associated with Lambda-CDM did anything to change their opinions, so that when it came to presenting conceptual alternative cosmological models, I was not speaking to a very receptive audience.
Having recently attended the Euclid meeting discussing the history and future of Lambda, and having heard the astronomers’ pleas for new thinking from the cosmology community, this leaves me very concerned that there is a major disconnect between the two communities and that cosmologists are just not taking up the challenge thrown down to them by the astronomers. That does not bode well for a speedy resolution to the crisis in cosmology that so may scientist do believe exists today.
