Modern physics

Modern physics refers to theories and discoveries that emerged in the early 20th century, fundamentally changing our understanding of the universe. It includes concepts like relativity, which explains how time and space are interconnected, particularly at high speeds or strong gravitational fields. Quantum mechanics describes the behavior of particles at very small scales, highlighting that energy and matter can behave unpredictably. Together, these theories reshape our perspective on reality, revealing a universe that is more complex and interconnected than previously thought, influencing technology, cosmology, and fundamental science.
