Can someone please explain something too me. From what I understand our current calculations suggest the universe is between 11 and 20 some billion years old. Astronomers have measured the cosmos to be roughly 156 billion light years across, or 78 billion light years from the outermost edge to the center. Since nothing can travel faster than light, how could matter have expanded a minimum of 78 billion light years in 11-20 billion years? Am I missing something?
