What If Gravity Was 2x Stronger?

What would happen if Earth's gravity suddenly doubled overnight? 🌍⬇️ You'd wake up weighing twice as much. Your heart would race just to push blood to your brain. Stairs would feel like mountains, jumps would shrink to half their height, mugs would hit the floor 41% faster — and old buildings and bridges might not survive the extra load. In this animated what-if, we follow Leo, Nova, Kip and the Doctor through a single day in a 2G world — from the moment gravity switches, to sports, buildings, nature, planes, rockets, and how life itself would evolve over a million years. ⏱️ Chapters 0:00 A normal night 0:16 Gravity doubles 0:33 The next morning 0:58 Mass vs weight 1:16 Your heart at 2G 1:40 The physics of 2G 2:12 Walking & why kids cope better 2:40 Climbing stairs 2:58 Falling objects 3:24 Basketball & jumping 3:52 Football & world records 4:18 Buildings & bridges 4:44 Nature, rain & air pressure 5:06 Planes & rockets 5:30 Evolution in a 2G world 5:52 Gravity restored 6:08 Would YOU survive? 💬 Would you survive a 2G world?
