I've seen a previous threads where it was a mathematical consistency based on four-dimensions, and a host of other reasons. I'm currently trying to reconcile my belief that it has to do with time dilation and the observer effect.
I've read that. I am completely a layman in this rodeo. That math seems to be the only refuge for some. I was hoping that knowledgeable people here could possibly tell me if the observer effect had any bearing on two observable quantities, both being the speed of light.jedishrfu said:
The "c2" in E=mc2 stands for the speed of light squared. This is a constant value that represents the speed at which light travels in a vacuum, which is approximately 299,792,458 meters per second.
Einstein used the speed of light in his equation because he discovered that it is the fastest speed in the universe and is constant regardless of an observer's frame of reference. This led him to believe that it is a fundamental property of the universe and must be incorporated into his theory of relativity.
Einstein's idea of using the speed of light in his equation was based on his theory of special relativity. This theory states that the laws of physics are the same for all observers, regardless of their relative motion. Through his thought experiments and mathematical equations, Einstein showed that the speed of light is a fundamental constant that is intertwined with space and time.
The significance of c2 in E=mc2 is that it represents the relationship between mass and energy. By multiplying the speed of light squared by the mass of an object, it shows how much energy is equivalent to that mass. This equation has revolutionized our understanding of the universe and has been used in many scientific discoveries and technological advancements.
No, the c2 value in E=mc2 is a constant that does not change. The speed of light is considered to be one of the fundamental constants of the universe and has been measured to be the same for all observers. Therefore, the c2 value will always remain the same in Einstein's famous equation.
