[vsnet-chat 1292] Re: Supernovae and an accelerating Universe

[bas@lowell.Lowell.Edu (Brian Skiff)]

     Mario Hamuy, one of the principals in the Calan/Tololo survey in Chile,
recently gave a presentation in Flagstaff about their work on high-z 
supernovae and the cosmological implications.  This included some of the
evidence for non-zero cosmological constants, etc.  The basic observational
evidence is fairly compelling, although there is some room for possible
systematic errors that would lead to erroneous results.  Even though the
results are not utterly conclusive, they do provide real observational data
to constrain models in a field where it is still customary to heap
unverifiable assumptions upon one another to see what emerges.  (The very
many quite pointless cosmology papers appearing on the LANL preprint server
provide ample evidence of this.)
