We compare the peculiar velocities of nearby SNe Ia with those predicted bythe gravity fields of full sky galaxy catalogs. The method provides a powerfultest of the gravitational instability paradigm and strong constraints on thedensity parameter beta = Omega^0.6/b. For 24 SNe Ia within 10,000 km/s we findthe observed SNe Ia peculiar velocities are well modeled by the predictionsderived from the 1.2 Jy IRAS survey and the Optical Redshift Survey (ORS). Ourbest $\beta$ is 0.4 from IRAS, and 0.3 from the ORS, with beta>0.7 andbeta<0.15 ruled out at 95% confidence levels from the IRAS comparison.Bootstrap resampling tests show these results to be robust in the mean and inits error. The precision of this technique will improve as additional nearbySNe Ia are discovered and monitored.Comment: 16 pages (LaTex), 3 postscript figure
