You fall off a roof. Gravity is pulling on every atom of you, and you feel absolutely nothing. That one strange fact sent Einstein from a patent office desk to a whole new picture of space and time. By the end of this lecture you’ll see why your sense of “weight” was never gravity at all, why light falls, and why the clock in your attic runs faster than the one in your basement. 0:00 The force you can’t feel 2:15 The paper cup trick that switches gravity off 5:40 Newton’s two masses: a coincidence nobody could explain 10:30 The happiest thought of Einstein’s life 13:45 You can’t tell falling from floating 17:20 Astronauts are NOT in zero gravity 21:30 The rocket box that bends light 26:00 Why time runs slower downstairs 30:30 The one thing falling can never erase 34:30 Gravity isn’t a pull.
