Started reading this thread but it seemed to get hijacked by someone 'silly' who objected to language.
1. Are the oldest objects we can see also the farthest away?
2. If the farthest away object we can see is
a. is the size of the universe 2x that distance? (i.e. if it took light from some distant quasar / galaxy 13 billion years to get here, presumably its light has also been travelling the same time and distance in the opposite direction, right?), or is it,
b. (the object's speed away from us x 13 billion years) + "a". (see above: 13 billion years x 2) -
3. If our solar system is 4.6 billion years old, and the universe is only 13 billion years old, given the present theory that heavy element formation requires several stars to form and supernovae to seed the star/planetary disk with heavier elements - can enough stars form and supernovae in the first 2/3 of time since the big bang to create sufficient raw materials for our solar system to have formed in the last 1/3?
