In a recent paper published in Monthly Notices of the Royal Astronomical Society: Letters, a group of astrophysicists from the University of Canterbury in New Zealand questioned that Nobel Prize-winning finding. Analyses like the one in the new paper, depend a lot on their assumptions (priors) and the data used, and I would not be surprised if another group soon claims that Lambda cold dark matter is superior after all.
