The Properties of Light and Time
This paper presents a possible explanations of how light can travel as both a particle, and as a wave. Two theories are presented on what may cause light to alter its direction when passing near a sun. The paper concludes with a discussion about the properties of time, and how variations in the rate of time can coexist within the universe.

The Properties of Matter and Space
From our observations of gravity we learn that something in the mechanics of gravity has the ability to both store and release energy, and that this energy can exert a force on physical matter. From the propagation of gravity waves we learn that spacetime is a continuous entity.

An Alternative Theory of Gravity
This paper steps away from the current theory that gravity does not exist; instead it presents four possible models that could explain the mechanics of gravity. The paper goes on to explain how the force of gravity is applied to the Moon and the Earth. The paper concludes that gravity is a ‘pushing’ force, not a ‘pulling’ force.

Review of the Paper - What Is Time And What Causes Time?
Several issues have been identified within Dr. Khan’s paper, including his statements that gravity is not a force, that time is caused by the expansion of space, that an object of mass must be moving in order to curve spacetime, and that inertia is related to the curvature of spacetime.
