I recall my 'matter-gravity entanglement hypothesis' and briefly review theevidence for it, based partly on its seeming ability to resolve a number ofpuzzles related to quantum black holes including the black hole informationloss puzzle. I point out that, according to this hypothesis, there is aquantity, i.e. the universe's 'matter-gravity entanglement entropy' -- whichdeserves to be considered the 'entropy of the universe' and which, withsuitable initial conditions, will plausibly increase monotonically withcosmological time. In the last section, which is more tentative and raises anumber of further puzzles and open questions, I discuss the prospects for anotion of 'events' which 'happen' whose statistical properties are described bythis entropy of the universe. It is hoped that such a theory of events may be astep on the way towards explaining how initial quantum fluctuations convertthemselves into inhomogeneities in a seemingly classical universe.
