There are some unresolved paradoxes and inconsistencies in special relativity and general relativity. This paper is an attempt to fix them all. I presented the true version of relativity. And it is shown conclusively that speed of light cannot be same with respect to source or observer. Simultaneity is absolute. Galilean invariance is indeed deep symmetry of the universe. And it applies on the speed of light too. In Michelson and Morley experiment there is simple addition and subtraction of velocities with respect to source and mirror so that is why there is no fringe shift when apparatus moves with a certain velocity. In moving conductor and magnet problem, in both cases same phenomenon is involved. If the conductor is moving there is Lorentz force on the moving charges in the conductor. And if the magnet is moving then there is same force involved i.e. Lorentz force on charges. Maxwell’s equations cannot be used to determine that the speed of light is constant for all inertial frames. I conceived that the flaw is not in Galilean invariance but in Maxwell’s electrodynamics. 3 × 108 m/s is not the speed limit of the universe. When a galaxy goes away it gives red shift. It is because of photons or light slows down. There is simple addition and subtraction of velocities. Light behaves just like other particles. Speed of light is not constant. Time dilates and inertial mass increases as an object moves. In gravity there is increase in time dilation and increase in inertial mass. Equivalence principle is not very extraordinary. No matter how much you curve spacetime it will not result in acceleration. The idea of spacetime curvature seems unrealistic and fictitious.
