Mount Everest gets about 4 millimeters taller every year as the Indian subcontinent continues to smash into the Eurasian tectonic plate beneath the Himalayas. 🏔️📏
Every object with mass has a Schwarzschild radius. If you crushed planet Earth down until it became a black hole, it would measure just 1.8 centimeters across: the size of a marble. 🌍
Earth's tectonic plates drift across the mantle at roughly the exact same speed that your fingernails grow: about 2.5 to 3 centimeters (1 inch) per year. 💅🌍
