Dark Energy Wins Again
dark energy is really getting a high profile these days. the 2007 gruber cosmology prize was just awarded to the two teams that discovered the presence of dark energy in 1998: saul perlmutter (the supernova cosmology project) and brian schmidt (the high-z supernova search team). wonderful news. read more here. now, if we could just figure out what dark energy actually is, we'd be even better off. most recent suggestion, made by brian greene and janna levin, is that dark energy is lurking in hidden dimensions. if someone understands what that means and can explain it to me, please send me an email and we'll chitchat.

There were a whole bunch of STScI people on those teams.
The exact nature of dark energy (and dark matter) is the thing that really turns me off. It seems that so much of it is untestable. Untestable things aren't really science, they're religion.
I once heard Caldwell prostulate that dark matter might just be matter on other branes parallel to our own. Basically, all that you'd need is to have gravity be able to pass from brane to brane. No one has proven that it can't happen...
