Tutorial: Relativity of simultaneity

[geistkiesel]

Hi geistkiesel,
If the speed of light is constant in all frames, then all observers of an expanding EM sphere will say that the sphere's centre is motionless in their frame, yes?

So how does this suggest an absolute motionless frame?

Your rhetorical question is answered in the negative, Postulates suck Pete,

There is a way to test th belief what all observers will see.
When the light is emitted have the light reflected back after moving a distance ct in time t. The light will reflect back a distance ct in time t.

If i told anyone to read Feynman;'s Lectures ion Physics, it would be only ch 5 vol III. The chapter you refer to is not of great interest to me for the simple reason I have not read it in detail. I am a Feynman hunter. I look for mistakes the man made that are of such a level of signifcance to science and physics that I am motivated enough to comment.

If I did urge you to read 34-7 I cannot remember the context of why I would reccomen 34-7.
I tell you what though, johnny5, I will read the article and comment.

The last sentence in 34-7 says

"The angular momentum is never "completely along the z-direction.".
Did Feynman prove this in 34-7? Or more generally is the statement true and true for what fe3hynmansaid. Remember he equated quantum mechanics with classical models, which stinks as far as I am concerned.

Well I was only wondering why you asked me to read it is all, i guess it doesnt matter.
