Re: fantasy relativity

Heya everyone,

        Hope you all had some good holidays. :)

In our last episode, Alex James said:

        Hit the books a bit harder. :)  There is no such thing as a
"stationary" observer.  It's all relative -- hence, "relativity".

        Well, look at my longer post, which covers that.  Or, check
out

        Light is *always* travelling at C, no matter how fast you're
moving.  It moves that fast for everyone -- the crew on the ship travelling
near C as well as the a "stationary" observer.

        Can some of you physics types comment on this?  Am I wrong about
all this?
