We know that the universe contains lots of different kinds of particles. What are they? In this one I discuss every Thing in the universe. The answers are pretty surprising! This is the fifth of the videos in my new series of Cosmology. I'm going through Dr. Barbara Ryden's textbook "Introduction to Cosmology". I used this textbook at William Paterson University. This course will cover the current state of the science of Cosmology. Here are the topics of this video: Introductory Cosmology Chapter 02: Fundamental Observations Section 04: Different Types of Particles Some things covered: Elementary Particle Physics Quarks, Leptons, Bosons and Hadrons Introductory quantum chromodynamics Baryonic and non-baryonic matter Photons and the blackbody distribution Neutrino flavors and their mysterious masses Dark matter Baryonic Matter: Exotic Matter: Proton decay searches: Neutrino Mass Bounds in the era of Tension Cosmology: Diagram for neutrinos: S Adrián-Martínez et al 2016 J.
