Geodesic

A geodesic is the shortest path between two points. Imagine that you want to get from one place to another in the fastest way possible. To do that, you need to find the shortest way, which would be like a straight line. That's what geodesics do. They take the shortest path to get from one place to another. It's like drawing a line on a map to go from one place to another. They can be used in real life, Like when you plan a road trip and you want to find the shortest route possible. But they can also be used in mathematics and physics. Geodesics are a way of helping to understand and visualize the concept of curved space.
