How did the achievements of Balboa and Magellan change the way in which people viewed the world?

The achievements of Balboa and Magellan significantly reshaped perceptions of the world by revealing the vastness and interconnectedness of the oceans. Balboa's discovery of the Pacific Ocean demonstrated that there were extensive waters beyond the Americas, while Magellan's circumnavigation of the globe provided concrete evidence of the Earth's roundness and the existence of diverse cultures across different continents. These explorations expanded European horizons, leading to increased interest in global trade, colonization, and the exchange of ideas and goods, fundamentally altering the worldview of the time.
