New flat world map is two-sided and round letting users flip it over Stacy Liberatore For Dailymail.com
Astrophysicists have re-imaged our planet as a map that you can hold in your hand.
A team from Princeton University shared a new world map that is less distorted due it being two-sided and round, similar to a phonograph record.
The map can display the Eastern and Western Hemispheres on the sides or the Northern and Southern Hemispheres, which allows the equator to run around the edge.
The double-disk map minimizes all six types of map distortions, shows Antarctica and Australia more accurately than other maps, along with the distance across oceans and poles - it is also easier to measure.
