  Comparison of galaxy flows with those predicted from the local galaxy
distribution ended as an active field after two analyses came to vastly
different conclusions 25 years ago, but that was due to faulty data.
  All the old results are therefore suspect. With new data collected in the
last several years, the problem deserves another look.
  For this we analyze the gravity field inferred from the enormous data set
derived from the 2MASS collection of galaxies, and compare it to the velocity
field derived from the well calibrated SFI++ Tully-Fisher catalog. Using the
"Inverse Method" to minimize Malmquist biases, within 10,000 km/s the gravity
field is seen to predict the velocity field to remarkable consistency. This is
a beautiful demonstration of linear perturbation theory and is fully consistent
with standard values of the cosmological variables.
