The Cosmological Zoo: Particles in the Universe

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". If you follow along, you'll get a full upper-division undergraduate course in Cosmology. I used this textbook at William Paterson University.

This course will cover the current state of the science of Cosmology. To follow along, it'll be a good idea for you to ge to know your calculus. 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

Jason is a person who I like without limit. He is guiding us through the theories that exist. Nothing more. And as such you should listen to him as the most efficient way to get current. His plan seem to be in the fold .... good plan .... anyways he read up on everything he is saying.

I love this lecture series!! Thank you. I’m glad all went well in NM!

I hadn't realized you just recorded these videos from your lectures following a textbook you do it so well. You're passion towards both astronomy and educating really shines through... such a wonderful combination...

[shashilwow]

Awesome! I'm slowly starting to understand all of this and your videos are helping a lot.

This is a wonderful series. Makes want to retake all my math classes from college! If I had only known!

[pressureswitch]

Thanks for this overview of cosmological particles! Really enjoying the series!

Sorry missed the Premier: was watching another mate on a stream.

23:05 I have problems with understanding Photons! is a single Quant_of_Pht really a travelling packet of ELM_vibration in a "line" or is it a 3D_Sphere, expanding at c and "gaining" direction only at Time of Detection/Absorption?
But then again how to explain Lasers? (which always are a multitude od Quanta)

I am becoming increasingly convinced of higher quarks being found in the quark/gluon soup found at the cores of neutron stars. Their energy being sustained by the gravitational contraction as they ecrete matter at the surface. There is however, only theories, no way of ever proving it. But like the dubious, mathematical failure of the singularity at the cores of BH's, it makes most sense to me if there were.
Great lecture Mr. Kendall, thank you.

Excellent stuff. Professor Kendall, is there a better explaination for dark matter that doesn't involve inventing a band-aid material? Could it be a magnetic process or something similarly non-arcane?

[robertfraser]

Excellent ! Re dark matter.. Neil Turok suggests that the dark matter particle is a heavy right handed neutrino (as a result of one of the left handed neutrinos being zero mass ). If the zero mass is established in next few years he could be onto something !!
