  The flat matter dominated Universe that dominated cosmological model building
for much of the past 20 years does not correspond to the Universe in which we
live. This has profound implications both for our understanding of dark matter,
and also for our understanding of the future of the Universe. I review recent
developments here and present best fits for the current, sometimes crazy,
values of the major measured fundamental cosmological parameters. (Invited
review talk, 9th International Workshop on Neutrino Telescopes, Venice, March
2001. Note: this is an updated version of an article prepared for the
proceedings of IDM2000 in York, UK.)
