somebody got a transcript of Hawking's 21 July talk at dublin to the blogger/cosmologist and generally cool guy Sean Carroll and Peter Woit, the mathematician blogger of Columbia U and Not Even Wrong fame, passed the link on to us http://pancake.uchicago.edu/~carroll/hawkingdublin.txt So I printed out these words of Hawking and sit reading them they are no-formulas, readable, and fairly much for general audience He says among other arresting things: "There is a problem describing what happens, because Strictly speaking, the only observables in quantum gravity, are the values of the field at infinity. One can not define the field at some point in the middle, because there is quantum uncertainty in where the measurement is done." I dont know if I buy that. One observes correlations of measurments made in this life in one's own backyard---I would have thought----not at infinity. the entertainment of this talk is high, and it is very well written I'd say, but there is something whole-hog-graphic about it (pun chuckle chuckle) that I mistrust.
