Repack - Modern Physics

This transition gave birth to , a field defined by two revolutionary pillars: Relativity and Quantum Mechanics . 1. The Large Scale: Einstein’s Relativity

For the first two hundred years following Isaac Newton’s Principia Mathematica , physics told a comforting story. It was a story of cause and effect, of predictable clockwork planets, and of billiard balls moving along deterministic paths. This was —the physics of the large, the slow, and the everyday. modern physics

Ten years later, Einstein unveiled , which redefined gravity. Newton thought gravity was a force pulling objects together. Einstein proved gravity is geometry. Massive objects like the sun do not "pull" on the Earth; they warp the fabric of spacetime around them. The Earth is simply following the curved path in this warped fabric. This theory predicted black holes (regions where spacetime warps infinitely) and gravitational waves (ripples in the fabric of the universe), which were finally detected a century later in 2015. It was a story of cause and effect,
