The Size and Age of Our Universe If the universe is 14 billion years old, (roughly) then we can only see out in any direction for 14 billion light years. Thus any stars beyond 14 billion light years are invisible to us because their light hasn’t had time to reach us. If we cannot find an edge within 14 billion light years, then we are farther than 14 billion light years from an edge. Therefore wouldn’t this imply that the universe may be older than we have the ability to discern? And if the universe isn’t a perfect sphere, what then? Do we try detection methods that utilize particles that travel faster than light? Or are we using another method entirely to determine the age and size of the universe?
