Some time ago I was doing my dissertation on inflation and wrote to Martin Bojowald to ask if loop quantum cosmology was compatible with eternal inflation or not. He said at the time that no work had been done on the subject but it might be something to look at in the future. I have now found a paper entitled "Loop quantum multiverse?" he gave a seminar on it a few days ago, but it seems that paper went to the arxiv a few months ago: http://arxiv.org/pdf/1212.5150v1.pdf i think he is suggesting a multiverse might arise in a rather different way than is usually suggested in the eternal inflation scenario. Has anyone read this paper? Is this correct? Any thoughts?
