“The currently (2010) widely accepted/believed description of the birth and evolution of the universe and of its contents is "Lambda Cold Dark Matter Concordance Cosmological Model" (LCDM CCM) … My own research was very much confined to the early version of the LCDM CCM (mid-1990's) when I began performing numerical experiments on the satellite galaxies of the Milky Way. I was quite happy with the CCM, as everyone else, and did not bother with the fundamental issues raised by some. With time, however, it became apparent that the LCDM CCM accounts poorly for the properties of the satellite galaxies and their distribution about the Milky Way. Warm dark matter models fared no better.”

Beautiful Minds (2010)
Context: I have this sense that we need to picture cosmology, the evolution of the universe in a whole new way. I'm probably not one that can achieve this new thinking but somebody will and I feel at the moment we're kind of waiting for it to happen. A bit like a pregnant pause. A bit like what happens when there's a snowfall, first snowfall of the year, when everything goes quiet and kind of waits. I feel we are in that kind of phase.
