Bi-metric Types Theories of Gravity: The Problem of Motion


Bi-metric theories of gravity are regarded as alternative theories of gravity dealing with strong gravitational fields. From this perspective, equations of motion for different particles of various characteristic behavior such as charged or spinning ones are obtained. Also, equations of path deviation associated for each type of particles are derived. It is worth mentioning that studying the problem of motion may be used to examine the stability of orbiting object near strong sources of gravity. Also, the dark matter problem can be expressed as an equation of motion for a variable mass in the presence of strong field of gravity.
