>Aliens living 14.6 billion LY away from us see a Universe that looks just like what we see in all directions.
How's that? Won't they see a completely different universe due to the speed of light? If they're 14.6 billion light years away from us, and they in our direction, won't they see what was happening in this area 14.6 billion years ago?
He doesn't mean the aliens will see an exact duplicate of what we see but that the universe is uniform enough that what they see would have the same properties (density, etc.) as what we see.
