  1. Just can't make sense of it. If we can look in one direction, and see an object 10 billion light years away, and look in the opposite direction and see an object 10 billion light years away, that would suggest a universe that was at the very least, 20 billion light years wide, 10 billion years ago. The universe has continued to expand in the mean time, and those two objects are even more distant from each other now.

    Neglected to type the implied question. If the universe is 15 billion years old, the two objects only had 5 billion years to get separated by 20 billion lightyear's distance, which means they were separated at a rate much greater than the speed of light. (twice the speed?). Isn't this impossible?

    And if we would discover an object 11billion lightyears away, and look in the opposite direction with the same technology and discover a similar object 11billion light years away, that would put those two objects, each at an age of 4 billion years, with a separation of 22 billion lightyears. Hypothetical 12 billion lightyear distant objects, 3 billion years old separated by 24 billion lightyears, 2billion year olds by 26 billion lightyears, 1byearolds by 28bly, and so on, till we find the earliest things we can see, at the GREATEST distance of separation. Doesn't this imply that the universe was BIGGER when it was younger? Where am I going wrong?
