Listen to a physicist talk about quantum mechanics, and you'll hear the word "observable". Observables are, intuitively enough, things that can be observed. They're properties that, in principle, one could measure in an experiment, like the position of a particle or its momentum. They're the kinds of things linked by uncertainty principles, where the better...

[AI summary] The text presents a comprehensive list of fundamental and unresolved questions in physics and cosmology. These include the nature of the universe's dimensionality, the values of fundamental constants, the origin of mass and force strengths, the unification of forces, the structure of spacetime, the existence of dark matter and dark energy, the nature of quantum gravity, and the possibility of a mathematical formulation of quantum field theories. It also touches on the Anthropic Principle and alternative theories like cosmic Darwinism, as well as the challenges of testing string theory and M-theory. The text emphasizes the depth and complexity of these questions, highlighting the lack of definitive answers and the ongoing scientific debate surrou...
