What If Earth’s Gravity Doubled?

What if Earth's gravity doubled overnight? Your phone falls before you can blink, a short climb up the stairs feels like a mountain, and your 70 kg body suddenly weighs 140. Old dams crack, tides rise ten times higher, and everyone has to learn to walk again... until one day all that extra strength gets you somewhere nobody else can reach.

Science notes: Earth's gravity accelerates you at 9.8 m/s²; at 2x it's 19.6 m/s². Fighter pilots train to handle up to 9 g, but only for seconds; 2 g all day is a different problem. With twice the air pressure, water boils at about 120 °C, which is exactly how a pressure cooker works. #whatif #animation #stickman #science
