This is what Earth looks like when you map its gravity. We normally picture Earth as a smooth sphere, but gravity isn't exactly the same everywhere. Differences in mass beneath the surface create small rises and dips in something called the Geo-ID. This animation is based on real gravity data from ESA's GOCE satellite mission, which measured Earth's gravity field and helped scientists map the geowid in detail. For example, one of the largest geoid Lows is in the Indian Ocean just south of Sri Lanka, where the geoid is about 106 meters lower than the reference surface. One of the largest highs is east of New Guinea, where it rises by roughly 85 meters. But the bumps and dips you see here are heavily exaggerated. The real differences are much smaller, so the shape is stretched to make them visible. This strange shape isn't fictional. It's based on real measurements of how Earth's gravity varies across the planet.
