Cara menjelajah Spacetime Curvature 3D Explorer
Open the Spacetime Curvature 3D Explorer, read r_s = 2GM/c^2 with Sun ~2.95 km, then switch Earth / Sun / 10 Msun BH to deepen the teaching grid.
- Open https://freetoolonline.com/space-3d/spacetime-curvature.html and wait for the curved grid and teal geodesics.
- Read the facts panel: 2GM/c^2, Sun ~2.95 km, Earth ~8.87 mm.
- Press Earth, Sun, and 10 Msun BH to compare depth.
- Toggle geodesics and the exaggerated r_s ring.
- Compare with Gravity Well 3D for escape velocities, or Light Cone 3D for flat causal regions.
