"When most scientists talk about progress in their field, they speak about small, incremental changes that slightly, gradually improve our understanding of how the Universe works. But when we think about the biggest advances in scientific history, they often occur in revolutionary leaps, completely overthrowing our previously held views of how the Universe works. In particular, revolutions like Special Relativity and General Relativity, quantum mechanics and quantum field theory, and the Big Bang and cosmic inflation completely overthrew our prior picture of how things actually behave. As the "holy grail" of physics, many have long sought a Theory of Everything, seeking to explain every particle, phenomenon, and interaction in all the Universe within a single framework, and possibly even with a single equation."
"Many attempts have famously been made in the past. Theodor Kaluza added extra dimensions, attempting to unify gravity with electromagnetism. Bryce DeWitt and John Wheeler pioneered approaches to a quantum theory of gravity. A slate of physicists, including Howard Georgi and Shelly Glashow, proposed unifying all the forces of the Standard Model in Grand Unified Theories. And string theory seeks an even grander prize, as an attempt at a true Theory of Everything. Thus far, these (and similar) ideas have failed to lead to a discovery of new physics, or to observations that bear out their predictions. But could that all change with the field of positive geometry? That's what Stephen Johnson wants to know, asking:"
"There's no shame in taking a big swing when it comes to any endeavor in life, and attempts at a Theory of Everything certainly count as swinging for the fences. Positive geometry has a chance, but it's got a long road ahead of it. Here's why."
Scientific progress usually occurs as small incremental improvements in understanding, but the greatest advances arise as revolutionary leaps that overthrow prior views. Revolutions such as Special Relativity, General Relativity, quantum mechanics and quantum field theory, and the Big Bang with cosmic inflation transformed foundational conceptions of the Universe. The search for a Theory of Everything aims to explain every particle, phenomenon, and interaction within a single framework. Historical attempts — including extra-dimensional unification, early quantum-gravity approaches, Grand Unified Theories, and string theory — have so far failed to produce confirmed new physics or observational support. Positive geometry is a young approach with promise but faces a long road of theoretical and experimental challenges.
