292 RELATIVITY, THE GENERAL THEOR
on asymmetries in the universe. There were discussions on the neutrino contents
of the universe and on the 3°K background radiation.
And there was discussion of quantum mechanics in general relativistic context,
not only of Hawking radiation, the important theoretical discovery of the 1970s
that particles are steadily created in the background geometry of a black hole, but
also of quantum gravity and supergravity. To the listener at this conference, these
last two topics, more than anything else, brought home most strikingly how much
still remains to be done in general relativity.References
