Cracking the Particle Code of the Universe: The Hunt for the Higgs Boson is a 2014 popular science book by Canadian physicist John Moffat.The first half of the book gives the reader an explanation of the particle physicists' Standard Model and the physical concepts associated with it, together with some possible alternatives to, and extensions of, the Standard Model.
This is a timeline of subatomic particle discoveries, including all particles thus far discovered which appear to be elementary (that is, indivisible) given the best available evidence. It also includes the discovery of composite particles and antiparticles that were of particular historical importance.
The Review of Particle Physics [2] (formerly Review of Particle Properties, Data on Particles and Resonant States, and Data on Elementary Particles and Resonant States) is a voluminous, 1,200+ page reference work which summarizes particle properties and reviews the current status of elementary particle physics, general relativity and big-bang cosmology.
The Solar System formed at about 9.2 billion years (4.6 Gya), [5]: 22.2.3 with the earliest evidence of life on Earth emerging by about 10 billion years (3.8 Gya). The thinning of matter over time reduces the ability of the matter to gravitationally decelerate the expansion of the universe; in contrast, dark energy is a constant factor tending ...

It is part of the first generation of matter, has an electric charge of + 2 / 3 e and a bare mass of 2.2 +0.5 −0.4 MeV/c 2. [1] Like all quarks, the up quark is an elementary fermion with spin 1 / 2 , and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions.
The simultaneous existence of the largest-known voids and galaxy clusters requires about 70% dark energy in the universe today, consistent with the latest data from the cosmic microwave background. [5] Voids act as bubbles in the universe that are sensitive to background cosmological changes.
