Gravity Is NOT A Force — Nobel Laureate Explains What Newton Got Wrong

Описание: Everything you learned about gravity is wrong. Newton's law of universal gravitation describes how gravity behaves, but not what it is. In 1915, Albert Einstein revolutionized physics with general relativity, revealing that gravity is not a force at all—it's the curvature of spacetime itself. Nobel Prize winner Sir Roger Penrose, who proved black holes are inevitable consequences of this curvature, explains why you're not being pulled down by Earth but pushed up by the ground, why free fall is the natural state of motion, how mass tells spacetime how to curve and curved spacetime tells mass how to move, and what geodesics really are. Discover the equivalence principle, learn why astronauts feel weightless even though Earth's gravity still affects them, understand how gravitational waves prove spacetime is physical, and explore why Mercury's orbit, light bending during eclipses, and GPS satellites all confirm Einstein was right. This is not abstract theory—this is reality. Gravity is geometry, and once you understand it, you never see the universe the same way. From singularity theorems to quantum gravity, from Newton's action-at-a-distance problem to Einstein's beautiful solution, this is the complete story of what gravity really is.
