Quote by Carl Sagan: “Imagination will often carry us to worlds that never were. But without it, we go nowhere.”

Sagan highlights imagination as a crucial engine for progress, even if it sometimes leads to unrealized possibilities. He argues that the capacity to envision new realities, even fantastical ones, is essential for innovation, discovery, and moving beyond current limitations in all fields of endeavor.
