All equations speak of a relationship. The relationship is the same no matter what number system is used.
Deducing the hypotenuse of a triangle by using the equation a2=b2+c2 from the Pythagorean Theorem is the same whether you use metric or imperial measurements, why because we are speaking of a relationship. So if we changed the number system and the Pythagorean Theorem didn't work we would know that it doesn't really speak of a relationship and is invalid as an equation. Applying this to e=mc2 , I will pretend that I come from a civilization where we measure all speeds in fractions of the speed of light. Therefore the speed of light =1. Hence in my civilization e=mc2 becomes e=m . Since the equation was able to be reduced to e=m for a theoretical civilization who measure speed as fractions of the speed of light then it should be e=m for all civilizations because the relationship cannot change based on a number system. If there is another formula which is the correct one then perhaps that's the one we should be using.
Except, e=mc2 will continue to work if the speed of light were expressed in fractions. It would be e=m ONLY when c=1. At lower fractions, let's say c=0.5, e=0.25m.
So, I don't know what you're getting at. :)
I am assuming C is being used as a constant and not as fractions of a constant. If the latter is true then I have learned something today. Thanks for your reply.
c is defined as a constant in our universe. Since you are changing to a universe where c=1, I'm adding another where c=0.5. That was my point. :)
Basically, it doesn't matter what c is - the equation will apply. If the c were 1, it's only a co-incidence that e=m.
yes i see , oh well back to the drawing board :)
I have been under the impression that we should always use the constant C in that equation not any fraction of C you like.
Exactly. And c = 299,792,458. Not 1.
It's only 299,792,458 because thats the way we measure it if we measured it in fraction of the speed of light then it would be 1. If changing the measurement system can cause the equation to go from e=mc2 to e=m then it was always e=m . Why can't I change the Pythagorean equation by changing how i measure things.
