Our theory of collective motions of open system [2,3] is generalized to the case of systems distributed in m -dimensional space. We propose a rigorous definition of a particle in terms of systems theory. A concrete image of a particle, conceived as a localized collective entity in Space, ...

What is a particle? 喜欢 0 阅读量: 6 作者:D Colosi,C Rovelli 摘要: Theoretical developments related to gravitational interaction have questioned the notion of particle in quantum field theory (QFT). For instance, uniquely defined particle states do not exist in general, in QFT on a curved ...

String theory is the idea in theoretical physics that reality is made up of infinitesimal vibrating strings, smaller than atoms, electrons or quarks. According to this theory, as the strings vibrate, twist and fold, they produce effects in many, tiny dimensions that humans interpret as everythin...
Albert Einstein's theory of general relativity describes how matter can curve space, so the matter's density can control the curvature and geometry of space on the largest scales. The key value is the "critical density," which is denoted by the Greek letter omega (𝛀). The universe has ...

particleis a vibrating string, according to string theory. The string's movement determines the type of particle and its characteristics, whether a photon, electron,gravitonor other type of particle. In this respect, a string acts much like a violin string whose vibrations determine the note and...
However, dark matter is harder to study than even that because it does not come conveniently clumped into super-dense balls likestarsand black holes. (That would be far too easy.) Instead, the primary theory of dark matter says that it is made of hypothetical particles called Weakly Interacti...
