Two groups are measuring distant supernovae with the goal of determining whether the Universe is open or closed by measuring the curvature in the Hubble diagram. The figure below shows both data sets: Perlmutter et al. (1997) and (1998) in black and Garnavich et al. (1997) in orange. The curves show a closed Universe (Omega = 2) in red, the critical density Universe (Omega = 1) in black, the empty Universe (Omega = 0) in green, and the steady state model in blue. ...
