The history of physics is the ongoing effort to understand the fundamental constituents of the universe and how they interact. It’s a journey spanning millennia, from ancient observations to modern-day breakthroughs. Key Characteristics / Core Concepts Ancient Astronomy and Mechanics: Early civilizations laid groundwork by observing celestial bodies and developing basic mechanical principles. Classical Physics … Read more
Time travel is the concept of moving between different points in time, much like traveling between different points in space. It’s a fascinating idea explored extensively in science fiction, but its feasibility is a complex question rooted in the intricacies of theoretical physics. Key Characteristics / Core Concepts Relativity: Einstein’s theories of relativity (special and … Read more
Relativity, in physics, refers to the theories developed by Albert Einstein that explain the relationship between space, time, gravity, and the motion of objects. It fundamentally alters our understanding of the universe at both very large (cosmological) and very small (subatomic) scales. Key Characteristics / Core Concepts Spacetime: Relativity unites space and time into a … Read more
Quantum Field Theory (QFT) is a theoretical framework in physics that combines classical field theory, special relativity, and quantum mechanics to describe the behavior of subatomic particles. It posits that fundamental forces and matter particles arise from the excitations of quantum fields permeating all of spacetime. Key Characteristics / Core Concepts Quantum Fields: The universe … Read more
