Same Planet… Opposite Extremes

What happens when the heaviest Earth and the lightest Earth collide? 🌍💥 In this Universe Sandbox experiment, we create two completely opposite versions of Earth: One becomes smaller and denser, gaining more and more mass The other becomes larger and lighter, losing mass as it grows We test 5 stages of extreme imbalance: 🌍 Equal Earths (normal) 🌍 2× size difference (one bigger & lighter, one smaller & heavier) 🌍 5× difference 🪐 11× difference (approaching Jupiter-size scale) ☀️ 100× difference (approaching Sun-size scale) As the gap increases, the physics becomes more extreme. In this simulation, you’ll see: How density vs size affects gravity When the heavy Earth dominates before impact Whether the light Earth gets torn apart instantly Shockwaves, debris, and orbital chaos The moment one planet behaves like a star-level object This experiment reveals a powerful truth: Mass and density matter far more than size in cosmic collisions.
