In popular perception of curved spacetime the metaphor of trampoline and a dimple on it is often used to explain general relativity.(adsbygoogle = window.adsbygoogle || []).push({});

I see that this may explain the spatial curvature and show how the only straight line in curved space around Sun for planets like Earth would be a timelike geodesic.

But can we explain Precession of the perihelion of Mercury which concerns the curvature through spacetime using the same metaphor of trampoline?
