I went to a rare maps convention today where vendors from all over the world brought in maps that went back hundreds of years. It's amazing to understand how the world was viewed by people from different time periods and more importantly, how we take for granted what we know about the world today. It was only a couple of hundred of years ago when South America was terra incognito and people thought Korea and California were islands.
This makes me wonder what we know today is wrong or off. What people see now as truth may only be one side of the story and we still have so much more to discover to understand the world around us better. It was common knowledge what the next town or city was just like how we now know the adjacent state or country. We barely know what's beyond our planet and solar systems and take for granted the world we think we know now. We must continue the search and drive to see what is at the limits of our understanding and not be afraid of what we find.
