I want to ask that what should be considered the most fundamental in physics I.e. whether the Standard Model or Dimensional units or the fundamental forces?
Finding a ToE is one of the major unsolved problems in physics.
Over the past few decades, a single explanatory framework, called "string theory", has emerged that may turn out to be the ultimate theory of the universe.
The most fundamental theory in physics is currently the Standard Model. This theory describes the fundamental particles that make up the universe and the forces that act upon them.
The Standard Model was developed through decades of experiments and observations by physicists. It was also influenced by mathematical theories and equations that were developed by scientists such as James Clerk Maxwell and Albert Einstein.
Yes, the Standard Model has limitations. It does not explain gravity or the behavior of dark matter, and it does not incorporate the principles of general relativity. Scientists are working on theories that could potentially unify the Standard Model with these other concepts.
The Standard Model has been incredibly successful in predicting and explaining the behavior of particles and forces in the universe. It has provided a framework for understanding the fundamental building blocks of matter and how they interact with each other.
Yes, there are several competing theories that attempt to explain the fundamental forces and particles in the universe. Some of these include supersymmetry, string theory, and loop quantum gravity. These theories are still being researched and tested, and it is not yet known if any of them will fully replace the Standard Model.
