"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."
