  Proceeding from a solution of field equations that are improved versions of
Einstein's nonvacuum gravitational field equations one is able to calculate
precisely the trajectories of particles traveling inside a nonrotating,
homogeneous, spherical body. Application of the results to the conditions of
recent measurements of neutrino flight times between a source point A at CERN's
European Laboratory for Particle Physics and a point B in either of two
detectors (ICARUS or OPERA) at LNGS (Laboratori Nazionale del Gran Sasso),
separated by a euclidean distance d(A,B) = 731 km, predicts for the flight time
from A to B of a 2 eV neutrino launched with energy 17 GeV, as measured by a
clock at B synchronized to a similar clock at A, approximately d/c + 9.3 x
10^{-16} sec. But as measured by inertial observers along the path the
predicted flight time is approximately d/c - 2.6 x 10^{-9} sec and the
predicted path length is approximately d - 8.4 x 10^{-7} m, which yields c +
321 m/sec for the predicted average inertially referenced speed of the neutrino
from A to B.
