Isaac Newton: Gravity Explains the Orbits

In 1687, Newton published Principia Mathematica, revolutionizing science.
He showed that gravity governs both falling apples and orbiting planets.
Newton’s laws explained why planets follow Kepler’s elliptical paths.
His universal law of gravitation united Earthly and cosmic motion.
Gravity decreases with distance but acts across the entire universe.
He introduced the three laws of motion that still guide physics today.
Newton proved the same forces shape tides, comets, and moons.
His work provided the foundation for classical mechanics.
For over two centuries, Newton’s model defined astronomy and physics.
His ideas remain essential, even as Einstein expanded them with relativity.
