This wouldn't work. For example, in the usual train car thought experiment, the light from the front of the car will be blue shifted and the light from the rear of the car will be red shifted for an observer in the car. But for an observer in the next car ahead both will be red shifted and for an observer in the next car behind both will be blue shifted. These three observers will agree on simultaneity (since they are all at rest wrt the train), but they will disagree on the Doppler shift.Nickelodeon said:Am i right in thinking that relativistic simultaneity explanations tend not to mention the fact that one of the ‘simultaneous’ events may well be red shifted and the other blue shifted and by analysing wavelengths you could presumably work out whether the event was in reality simultanous or not.
Look at it this way. There are two light sources. One is 1 light sec from you and stationary with respect to you and the other is coming towards you at some high fraction of c. When the moving source passes the stationary source, both emit a light pulse. Both light pulses leave at the same moment, and they both travel the same distance to reach you and at the same speed. The fact that you will see the pulse coming from the moving source as blue-shifted has no bearing on this.Nickelodeon said:Am i right in thinking that relativistic simultaneity explanations tend not to mention the fact that one of the ‘simultaneous’ events may well be red shifted and the other blue shifted and by analysing wavelengths you could presumably work out whether the event was in reality simultanous or not.
The theory of relativity is a fundamental concept in physics that was first proposed by Albert Einstein. It states that the laws of physics are the same for all observers in uniform motion, and that the speed of light is constant for all observers regardless of their relative motion.
The relativity of simultaneity is a concept within the theory of relativity that states that the perception of simultaneous events can differ between observers depending on their relative motion. This means that what one observer perceives as simultaneous may not be perceived as simultaneous by another observer.
The relativity of simultaneity has a direct impact on the perception of time, as it shows that time is relative and can be perceived differently by different observers. This means that what one observer perceives as a certain amount of time may be perceived as a different amount of time by another observer, depending on their relative motion.
Analyzing wavelengths is important in understanding the relativity of simultaneity because it helps to demonstrate how the perception of time and space can differ between observers. By analyzing the wavelengths of light, which are used to measure time and distance, we can see how the perception of these measurements can vary depending on an observer's relative motion.
The concept of relativity of simultaneity has greatly impacted our understanding of the universe, as it has shown that time and space are not absolute, but rather relative to an observer's frame of reference. This has led to a better understanding of phenomena such as time dilation and length contraction, and has also helped to shape our understanding of the universe on a larger scale, such as the theory of the expanding universe.
