Answer: The original meridian passes through the United Kingdom.
Some extra relevant information:
The Prime Meridian, also known as the Greenwich Meridian, is the line of longitude that represents 0 degrees longitude. It runs from the North Pole to the South Pole and passes through the United Kingdom, specifically through the Royal Observatory in Greenwich, London.
Established in 1851, the Greenwich Meridian was chosen as the international reference point for longitude due to the importance of British naval power and the accuracy of British sea charts at that time. The Royal Observatory in Greenwich played a significant role in the development of accurate timekeeping and navigation, further solidifying the choice of the Prime Meridian running through this location.
By convention, the Prime Meridian serves as the dividing line between the Eastern Hemisphere and the Western Hemisphere, allowing us to define time zones and accurately measure longitude worldwide. Its significance in navigation, cartography, and defining global time standards makes it an essential reference point for geographical and astronomical purposes.
It is worth noting that while the Prime Meridian passes through the United Kingdom, it does not necessarily imply that Greenwich is the center of the world. It merely serves as a globally recognized starting point for measuring longitude and establishing international timekeeping standards.
