We describe the implications of cosmic microwave background ( CMB ) observations and galaxy and cluster surveys of large scale structure ( LSS ) for theories of cosmic structure formation , especially emphasizing the recent Boomerang and Maxima CMB balloon experiments . The inflation-based cosmic structure formation paradigm we have been operating with for two decades has never been in better shape . Here we primarily focus on a simplified inflation parameter set , \ { \omega _ { b } , \omega _ { cdm } , \Omega _ { tot } , \Omega _ { \Lambda } ,n _ { s } , \tau _ { C } , \sigma _ % { 8 } \ } . Combining all of the current CMB+LSS data points to the remarkable conclusion that the local Hubble patch we can access has little mean curvature ( \Omega _ { tot } = 1.08 \pm 0.06 ) and the initial fluctuations were nearly scale invariant ( n _ { s } = 1.03 \pm 0.08 ) , both predictions of ( non-baroque ) inflation theory . The baryon density is found to be slightly larger than that preferred by independent Big Bang Nucleosynthesis estimates ( \omega _ { b } \equiv \Omega _ { b } { h } ^ { 2 } = 0.030 \pm 0.005 cf . 0.019 \pm 0.002 ) . The CDM density is in the expected range ( \omega _ { cdm } = 0.17 \pm 0.02 ) . Even stranger is the CMB+LSS evidence that the density of the universe is dominated by unclustered energy akin to the cosmological constant ( \Omega _ { \Lambda } = 0.66 \pm 0.06 ) , at the same level as that inferred from high redshift supernova observations . We also sketch the CMB+LSS implications for massive neutrinos .
