otion of particles of particles flow, particle flow impact of the retina caused vision. 18th century Newtons particles said the upper hand, the 19th century, it is volatile that accounted for an absolute advantage. The theory of ether is also greatly developed: the wave of the need for media transmission, light in the vacuum is the transmission of the media, also known as light ether. At the same time, the electromagnetism has been flourishing, through the Maxwell, Hertz and others efforts to form a mature electromagnetic phenomenon dynamics theory - electrodynamics, and from the theory and practice to prove that the light is a certain frequency range of electromagnetic waves , Thus unifying the wave theory of light and electromagnetic theory. The ether is not only the carrier of the light, but also the carrier of the electromagnetic field. Until the end of the nineteenth century, people tried to find the ether, but never found in the experiment ether, on the contrary, Michelson Morey experiment found that the ether is unlikely to exist.
　　The development of electromagnetism was originally incorporated into the framework of Newtonian mechanics, but in interpreting the electromagnetic process of moving objects it was found that the relativity principle followed by Newtonian mechanics was inconsistent. According to Maxwells theory, the velocity of electromagnetic waves in vacuum, that is, the speed of light is constant; however, according to Newtons method of velocity addition, the speed of light of different inertial lines is different. For example, two cars, one approaching to you, one away. You see the lights of the front car close to you, after a car light away. According to Galileo theory, the car coming to you will emit light with a speed greater than c (vacuum light velocity ^ 8m / s), that is, the speed of the light in front of t
