Regarding the expansion of space...
- In one book I've read the diameter of the universe is more than 100B light years across, even though the age of the universe is only roughly 14B years old. This is due to accelerated expansion of space.
- In another book it says that space is expanding in a "relativistic" way, so as the universe expands the length of a meter also gets longer, so the diameter of the universe doesn't change.
