Query: Geodesic Motions in AdS Soliton Background Space-time   We study both massive and massless particle's geodesic motion in the
background of general dimensional AdS-Sol space-time. We find that the massive
particles oscillate along the radial direction, while massless particles
experience one-time bouncing as they approach the "horizon" line of the
soliton. Our results provide a direct way to understand the negative
energy/masses leading to the AdS-Sol geometry. As a potential application, we
extend the point particle to a 3-brane and fix the background as a 5+1
dimension AdS-Sol, thus obtain a very natural bouncing/cyclic cosmological
model.
