Einstein's Cosmic Double Take

Technology Education Philosophy & Spirituality

Découvrez les différences fondamentales entre la relativité générale et restreinte d'Einstein, et comment ces théories révolutionnaires ont transformé notre compréhension de l'univers, du temps et même le fonctionnement de nos technologies quotidiennes.

Best quote from Einstein's Cosmic Double Take

Einstein proposed that gravity is not a force that attracts objects, but rather the curvature of spacetime itself; matter tells spacetime how to curve, and that curvature tells matter how to move.
