The quest to see what is ‘Over the Horizon’ has intrigued man for millennia. The desire to explore the world has led to much of it being extensively mapped, with people like Magellan, Carstensz and Cook being fine examples, but for centuries, the physical horizon was as far as we could see. For example, if you are 5’7” it would be just under 3 miles, whereas from the summit of Everest you can see over 200. This is why for centuries man has sought high ground. Defences always needed long distance views to see an enemy coming, and explorers want the best viewpoint into the unknown that they can get. This fact remained unchanged until the onset of the Telegraph and the Radio. Suddenly you didn’t need a semaphore or signal fires to communicate over distance. Within years, messages could be sent around the world, pushing the horizon far from view. But there is another horizon – limit of a person’s knowledge, experience or interest.
