ABSTRACT Recent cosmic microwave background ( CMB ) measurements combined with recent supernovae limits and other observational data have ambushed \Omega _ { \Lambda } and \Omega _ { m } . These cosmological culprits are trapped in a small pocket of parameter space : \Omega _ { \Lambda } = 0.62 \pm 0.16 and \Omega _ { m } = 0.24 \pm 0.10 . If this is correct then an unknown 2/3 of the Universe has been identified .
