Second Postulate of relativity tells us this,
In a funny way I’m going to look why we can really say the following,
“It is impossible that the speed of light has to be the same in all reference frames.”
Remember that light moves regardless the speed and the direction of the source. That means as soon as light emitted from any object in this universe, then any relationship between that object and the emitted light is evaporated, do not exist at all, and this is what missed the relativity.
Now the question is,
Observer on the reference frame where flash A and flash B, well see both flashes in the same time, Since the distance between the two flashes for that observer is the same and his reference frame is not moving.
Other Stationary or moving observer on another reference frame well see other timing for flash A before flash B and this due to the distance between hem and the two flashes A and B, and also due to his motion, direction and his speed.
“These two images from University of Pittsburgh trying to explain the Relativity of Simultaneity”
But when the that reference frame with the two flashes moves, and we know that light do not follow the movement of that frame, then also the observer on that frame has to see flash B before flash A, because what we said above, if the two flashes went on at the same time, then this already happened in a certain fixed point and from that point light well start to propagate, that means if the frame moves or not, light already happened in two points and it has to propagates in all direction in the same time at the same speed, Now, Since the frame with the observer are moving, but the light start points are fixed, then also that observer on the moving frame has to see flash B before flash A.
That means, that the two observers well see the flashes in other timing depends on their motion, thus they can never agree on the same speed for that light
Because; For the records, If you don’t know, Light is not waves, not photons and not even an electromagnetic waves, even worse there is no such thing, (Electromagnetic waves)….
This was add on July 25 2016:
As we mentioned above and as we all know, is the that Special Relativity been build on that idea that the light moves regardless of the speed and direction its source, and also that all observers in all reference frames has to agree on the same speed of the observed light,
I had to add this animation to make it easier for all of you.
When the spaceship at the right side moves with velocity V, and exactly at the point X it well flashes a light, and we know already from Annie Parker that light after emitting has nothing to do with its source, Then this has to happen:
- Right spaceship has to measure speed of that light as C – V,
- Left spaceship has to measure that speed as C + V,
- Jimmy Wortel (at the left corner below in the image) is an stationary observer, he has to measure the absolute speed of that light,
That means that all three observers well get another measured speed for the same light.
We have to pay attention that, also if the two ships having the same speed and although they don’t move relative to each other, they have to have different measurements for the speed of same light.
That means that all calculation of Special Relativity is not good.
Since, General Relativity is build on Special Relativity, Then I’m afraid to say, That the calculation of the General Relativity is also not that good.
I have no further questions your honor.
