Fundamental Theories

Fundamental theories are core ideas in science that explain how the universe works. For example, Newton's laws describe how objects move and interact; Einstein's theory of relativity explains gravity and the fabric of space-time. Quantum mechanics reveals how tiny particles behave randomly at small scales, and thermodynamics explains how energy flows and transforms. These theories provide foundational understanding that helps us predict natural phenomena, develop new technologies, and deepen our knowledge of the universe's underlying principles. They are tested, refined, and widely accepted because they consistently match observational evidence.
