I think you may be reading more into his words than he intended.

All he is saying is that two galaxies are separated by a distance of 20E6 ly in a universe only 15E6 ly old. Really not illogical when you consider that the two masses started traveling at high speed in opposite directions at the very beginning.

His conclusion, that those two galaxies will never be able to see each other or react with them in any way, is equally valid.

Of course, that is also making the rather LARGE assumption the we here on Terra Firma are at the absolute center of the Universe.

Or are astronomers going to claim they have found the exact center of everything? If they are now making such a claim, it'd be the first time I've ever heard it. ;-)

While this may imply that at least one of these galaxie is traveling faster than lightspeed, it remains plausible that they both may be 10 billion lightyears from earth, yet only 15 lightyears apart, or they may be travelling in opposite directions from the center.

I'm trying to recall high school geometry and trig here, but if we imagine the earth to be a point between two identical sides (10 billion lightyears long)of a triangle, and the ogirin somewhere along the opposite side (between the two galaxies), the distance between the origin and either galaxy (the other two points) may be up to nearly 20 billion light years, depending upon their angular distance from earth.

No. I understood that.

What I meant from my comments is that you never here astronomers saying "we can look 12 billion light years THAT way, but we can only see 3 billion light years in the other direction. This leads us to believe that the universe is only 15 billion years old."

From all the stories out there, it SEEMs like they looked in one direction 15E9 ly and said, "Well. I guess the universe is only 15E9 years old."

And yes, I fully realize that this probably isn't the case and that it probably reflects more on the piss poor nature of a reporters talents than it does on the hard science behind it.
