if this is true, then by turing 90 degrees, you can see a 10 billion year old galaxy in real time. Your local direction is not a determinate as to which way light is flowing.

look at this less as a vantage point from a car on a road versus other cars, but rather as standing on the top of a mountain marvelling at how far below you things are.

the 10 billion year old light reaching earth from a galaxy that far away is from the past. it has to be since it reaches us. I suppose if you wait, you can catch more recent light waves, but that takes real patience:-).

(OK, so I'm a spoil sport.(sigh!))

Not quite. You still aren't getting it.

If you can look 10 billion light years in one direction, and 10 billion in the other, and the Universe is SUPPOSEDLY only 15 billion years old, then the two galaxies at either end would have still been 5 billion light years apart when the Big Bang supposedly went off.

Got it?

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.
