PHD Comics: Gravitational Waves Explained Simple explanation but really interesting for further understanding on gravitational waves. "That's one small step for man, one giant leap for mankind" Neil Armstrong quote
Einstein's general theory of relativity suggests, among other things, that masses in space distort the geometry of space-time. In addition, moving objects emit waves of gravitational radiation that carry energy away into space.
An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that avoids the most baffling features of the subatomic universe.
