I don't know what's supposed to be so weird here. If 2 objects leave the same point at t=0, traveling in opposite directions at a speed of ~0.667c, then in 15 billion years they will be 20 billion light years apart. Big deal.

BTW, how do we know they didn't just *pass* each other at that point? :)

Well, friend, the big deal is that it took 15E9 years to get that galaxy to that distant point and another 10E9 years for the light to get back to us and that is a total of 25E9 years in a universe only 15E9 years old!

Whooops!

I agree with your assessment of the distances involved. Consider this as well, this guy's theory only really functions in reality if we are the center of the universe. Let's say we are on a fringe... how can we look behind us and see homogeneity to what is in front of us? Answer: science makes far too many assumptions.

From the article: "The weird implications of this become clearer if you imagine the earliest moments of the Big Bang. When the universe was a second old, and hence a light-second in radius, about 186,000 miles, opposite points on the circumference were twice that far apart, unbridgeable even by light. No matter how far back you go -- a millisecond, a microsecond -- the regions can never have been in contact. It is as if they exist as two separate universes."

I prefer to take this argument another direction. Let's go to the very nanosecond after the "big bang"... what was there before that nanosecond? Scientists too quickly dismiss creationism as fairy tale without acknowledging that their grand theories hold no water.
