This book aims at the following objectives: It is shown as to how the general motion under gravitational force can be formulated purely in electromagnetic and kinematic terms, thereby linking gravity and electromagnetism. That also means that "mass", that is generally viewed as a "fundamental quantity" is also expressible in terms of electromagnetism.Bring out how the inertial force, centrifugal force, Coriolis force and Euler force are the byproducts of motion through the electric field of planet. And also show how the above said formulation has the advantage that all these forces are not required to be calculated separately but can be curtailed into a single equation of classical electrodynamics itself.Propose an alternative hypothesis to explain the orbital motion of the planets, and also discuss its ramifications. The alternative hypothesis frees the burden of the three body problem and multibody problem that the existing gravity theories (Newtonian and Einsteinian) suffer from.
