On the 100th anniversary of Albert Einstein's Theory of General Relativity (gravity), many of the predictions of this theory have been proven correct. Here's the story of one that was wrong.
A clear and entertaining presentation of the double slit experiment that demonstrates the mind-bending wave aspect of matter, a result just replicated on a record-breaking molecule of 2,000 atoms. An excerpt from What the Bleep Do We Know?
This video is about how little we know about the behavior of gravity at short length and distance scales and constraints on Newton's inverse square law at the human and microscopic and atomic scales. Only on solar system scales or larger do we have good constraints on Newton's law of gravitation.
