Quantum Chromodynamics, which is an integral part of the Standard Model of Particle Physics, defines how quarks interact with themselves and each other to form particles such as protons and neutrons. The word quantum stands for the fact that interactions (forces between particles) on this level can be represented as things that occur only in … Read more
For the past 50 years, the Standard Model of Particle Physics has given us a complete mathematical description of the particles and forces that shape our world. It predicts with so much accuracy the microscopic properties of particles and the macroscopic ones of stars and galaxies that many physicists feel that it is the ultimate … Read more
The concept of a field was developed when physicists learned that they could simplify the calculations of the forces involved in planetary motion by assuming or imagining the existence of a continuous gravitational field. They defined this field in such a way that if another planet were put at any point in that field the … Read more
Is time an eternity or does it have a beginning and end? This question is very difficult to answer because current theories are only able to describe what happened after the beginning of our universe. In other words how the universe came about and whether there is any meaning to a “before” or “after” is … Read more
Is it possible to define the “reality” behind the quantum world in terms of the classical laws of physics. For example the paradoxical wave–particle behavior of energy/mass, one of the fundamental concepts defining Quantum mechanics defies the “reality” of a classical world because of its inability to describe/define how quantum-scale objects can simultaneously exist as … Read more
