Caption notes
Derek Muller uses a person in free fall and a spaceship coasting far from massive bodies to illustrate the experience of weightlessness in a local reference frame. A thought experiment with two people heading north along meridians shows how objects following geodesics can move closer together. The floor’s support provides a contrast between staying at the same coordinates and having an accelerometer read zero.
