I read in sci.electronics.design that Robert Baer wrote (in ) about 'breaking the speed of light article on howstuffworks.com', on Sun, 6 Feb 2005:
There is no 'center': the expansion is not from a point but from every point.
We don't know, and may never know, whether expansion at superluminal speeds is possible, because there is an event horizon where the expansion speed is C. We can get no information, as far as we know at present, from beyond that horizon, which is formally called 'the boundary of the observable universe'.
Yes, it does, because it presumes matter moving at superluminal speed.
GR isn't required for that. See above about the event horizon.
The conclusion is true.
