Query: Motion of Massive Particles in Rindler Space and the Problem of Fall at
  the Centre   The motion of a massive particle in Rindler space has been studied and
obtained the geodesics of motion. The orbits in Rindler space are found to be
quite different from that of Schwarzschild case. The paths are not like the
Perihelion Precession type. Further we have set up the non-relativistic
Schrodinger equation for the particle in the quantum mechanical scenario in
presence of background constant gravitational field and investigated the
problem of fall of the particle at the center. This problem is also treated
classically. Unlike the conventional scenario, here the fall occurs at the
surface of a sphere of unit radius.
