Poincaré half-space model. Take the open upper half-space \[\mathbb{H}^n := \{(x_1,\dots,x_n)\in\mathbb{R}^n \mid x_n 0\}\] equipped with the Riemannian metric whose components on the coordinate tangent vectors are \[g_{ij}(p) \;=\; g_p\!\left(\frac{\partial}{\partial x_i}\bigg|_p,\; \frac{\partial}{\partial x_j}\bigg|_p\right) \;=\; \frac{1}{p_n^2}\,\delta_{ij}.\] Geodesics are semicircles (or rays) orthogonal to the boundary hyperplane \(\{x_n = 0\}\).
The Apple event, for instance, that’s a pseudo-event. That’s not an event in the same way that a helicopter crash is an event. Because everybody at Apple knows what’s going to happen ahead of time. There might be a couple of surprises if the audience acts up, but they know what they’re announcing, they know roughly when they’re going to announce it, they’ve rehearsed. And so this is a knowable pseudo-event.
