Einstein said that the speed of a matter in universe cannot exceed the speed of light.
Is it correct for electric force transmission speed from one electric charge to other one?
What is transmission speed between each other?
Is the reaction delay of one of them speed of light time when we move another one?
Also same question for magnetic force interaction speed with each other.
And is there any particule theory about the subject as gravitation can be created by gravitons?
Thanks a lot for answers
