Re: Relativity of Simultaneity (Not Quite)

May 1 2016, 12:14 AM 

Many books show a passenger car. In it, a light source is set at the center and is sending light rays to the front and the rear. Now, this setting is altered partly. There are two light sources. The two are set apart the same distance from the center horizontally (and somewhat apart vertically). This picture will be incompatible with popular picture.

A passenger car is moving. To an observer stands on the ground, it is said that time dilation stands up. And also it is said, at the front and the rear end of the car, simultaneity is relative. Are the two compatible ?

Is it possible to state the following ? Sorry, I can not say it with certainty.

It is supposed that every point on the surface of a light sphere is simultaneous (to a moving observer also). A light sphere is possible to occupy optional position in space. So, optional two points in space are simultaneous at optional point in time.

A passenger car is standing. From the same height of the front and the rear inner walls each, a light ray is being sent downward at a 5 degree. At the center of the car, a tiny sensor is set. The sensor responds to two rays and the third light source is lighting. Now, the other passenger car is passing by. From this passenger car, the third light will be visible also. Regardless of its speed. Pictures on relativity of simultaneity (on a moving passenger car) will not stand up.

A Picture of a Moving Passenger Car

November 9 2017, 12:50 AM 

In above passenger car (often shown in books), light source is lighting and on the ground, an observer is standing. There is the second picture. In this picture, the passenger car is standing and another passenger car (in it, there is the observer) is passing by. Two pictures will deny Lorentz contraction and relativity of simultaneity.
