Re: OT: Gravity, Dark Energy, Universal expansion
Come on, man.
Its not 20B light years away.
Its 20B years away.
Those are completely different units.
The size of the *visible* universe (roughly, time since photons were released * speed of light) is different from the size of the universe (which depends on its topology)!
Also, you are stating that there exists a farthest point in the universe from somewhere. This implies that you are assuming a closed universe. Why? Evidence indicates a flat or very slightly open universe last I checked.
The crux of the matter is that "speed of light perpendicular to 3-space" is nonsensical, since distance and speed are both undefined for that.
