This application allows users to explore antipodal points on a 3D globe using Mapbox GL JS and Go Fiber. When a user clicks on any point on the globe, the application calculates its antipodal point* and smoothly flies to that location.

Inspired by Neil deGrasse Tyson's explanation of antipodal points: Startalk Short Video

Antipodal points are two points on a sphere that are diametrically opposite to each other. On Earth, they are sometimes referred to as antipodes. If you were to draw a straight line from one point through the center of the Earth, it would emerge at the antipodal point.

• Interactive 3D globe using Mapbox GL JS
• Click on any point to fly to its antipodal location
• Display of starting and destination coordinates
• Smooth animation using Mapbox's flyTo effect

• Go 1.16 or later
• Mapbox API token
