How Did Vikings Cross the Atlantic Without a Map or Compass ?

#Vikings #VikingNavigation #VikingAge
No map. No compass. Just open ocean in every direction for six days straight.
And yet Viking sailors hit their target — again and again — across nine hundred miles of North Atlantic. While Columbus, with every advantage his century could offer, couldn't figure out which continent he'd landed on.
How? The answer involves a crystal that reads invisible light, an ocean that talks if you know how to listen, and a wooden disc the size of your palm that scientists misunderstood for sixty years.
