Quote of the day by Newton, “If I have seen further, it is by standing on the shoulders of giants.” How Einstein demolished Newton’s gravitational theory and introduced the spacetime concept

Quote of the day by Newton: 915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 years, scientists relied on Isaac Newton and his law of universal gravitation from 1687. Newton said gravity is a force between masses. Einstein proved gravity is the curvature of spacetime caused by mass and energy. His equations solved the Mercury orbit anomaly of 43 arcseconds per century and predicted gravitational waves and black holes. Today, GPS satellites and modern cosmology depend on Einsteins spacetime physics. In truth, Einstein did not erase Newton. He stood on Newtons shoulders—and saw deeper into the universe.
