p62: "We could be witnessing the start of a revolution"
p69: "[...] the advent of the =EF=AC=81rst recognizable quantum gravitation=
al data
and it has revolutionized the =EF=AC=81eld. These data come from cosmology,=
and
many more are likely on the way [...]" (via inflation-magnification of
primordial quantum effects)
p91: "Why are the divergences of quantum general relativity worse than
those of the other forces? Because the other forces couple to charges
which are the same for all modes, whereas gravity couples to
stress-energy, which grows [...]"
