WTF are you off-topic posting this for .. do you think it fools anyone into
thinking you actually understand any of it .. for you have certainly proved
beyond a shadow of doubt that you have no idea about relativity.

Sue Can't see any real difference in a capasitor,or lightning bolt
Both their power comes from building up their negative chargethat is
released to the positive.It is natures balancing act. Bert

That is the idea. When nature has to balance a B
with an E we have a good opportunity to see what
she is really about.
