A viral map suggesting a direct sea route from India to the United States has sparked debate on the internet. The map claims that one can sail from India to the US without touching any land in a straight line. Billionaire Elon Musk expressed his astonishment at the concept. Some users argued that the line on the 2D map is not straight, but this is due to the curvature of the Earth. A 3D globe visualization was shared to clarify the concept.
