Gauge Symmetry | Fundamental Law of the Universe | Grand Unified Theories

Thanks for watching this video, which explores the concept of gauge symmetry and its role in understanding the fundamental law of the universe.
In this video we’ll walk you through:
- Mathematical concepts of gauge symmetry
- Gauge symmetry in quantum electrodynamics
- Gauge symmetry of quantum chromodynamics
- Gauge symmetry of weak interaction
- Unreconciled problems
What is gauge symmetry? What is the fundamental law of the universe? How do we estimate unify gravity with other 3 basic forces? All these answers in 10 minutes!

This is a really, really excellent video! I have been a student of physics for over 40 years, and i have a bachelor's degree in physics, but not having the graduate degree, I have always lacked the mathematical skills necessary to fully understand topics such as gauge fields and Noether's theorem. Thank you so much for finally giving me an understanding of these topics! Very much appreciated!! I still have some questions about this that I'm wondering if you could answer in a simple, visual manner such as what you did here. Perhaps i will get back to you once i have mulled things over and formulated my questions correctly. Again, thank you so much!

Just came from hearing Krauss explain this on JRE and he lost me. This gave me a much clearer definition to at least begin to understand. Thank you

[@RandomVariable007]

I have been waiting for this so long.

Hope you enjoy it!

Good job well done thanks.

Very nice video🙌I have been trying to understand gauge symmetry through many huge educational content creators including PBS,and i couldnt umderstand up until i watched your video

[@init_yeah]

Love this thanks

Symmetry is dual to conservation -- the duality of Noether's theorem. Simultaneity is dual to relativity -- Einstein. Same is dual to different. Time dilation is dual to length contraction -- Einstein, special relativity. Space is dual to time -- Einstein. Absolute time (Galileo) is dual to relative time (Einstein) -- time duality. "Always two there are" -- Yoda. Simultaneous events are observer dependent or relative to the observer. The observed is dual to the observer -- David Bohm. Duality creates reality.

Surely the dots is just a side effect of the computer program? Like a computer imo cannot measure reality as wee as a properly developed aware human (actually v rare these days tbh ppl spend more time looking at screens than actual reality so i see us losing our power to see certain spectrums of light over time)

6:50 LOL he says theyre called hádrons and 1 sec later calls them hādrons 😅

[@user-ht9db6bc9t]

Also, he calls Noether's theorem a no-ether theorem🤦‍♂️

Sorry to say these explanations are completely out of true. This is not the way to understand universe. Things are very simple and accurate. Adolescent Physicists complicates the things. Every body can easily understand how the electrons and positrons build up this material universe and what actually a electro magnetic wave is!

[@sammorrow8420]

Sorry to say, positrons are antimatter. Before you post a negative comment on a video, be sure to not make simple mistakes yourself.

[@Italianjedi7]

He’s not saying gauge symmetry defines the universe. He is merely showing that 3 of the 4 fundamental forces exhibit this similarity.

[@surendranmk5306]

@@sammorrow8420 That is not a negative comment. I have to remind you the truth. Science is allways late running. What you told is a ridiculous mistake about positron! Positron is anti particle to electron but not anti matter! Same way the electrons are anti particles to the positrons. Both are allways produced in pairs, never a single! Anti matter is different. If you want I'll explain you exactly.The whole material universe is made out of these pairs of particles. Standard model of particles is completey a scrap. Mr Murray gellman was a top class idiot! Yukawa too! Most of the physicists are idiots parroting astray driven physics. They do not know what is electric charge. They do not know what is a particle or em wave. They do not know what is gravitation. They, including you, are not thinking well about all this, just swallowing the adholescent ideas from adholescent physicists. Sorry, Mistake is with you gentle man! Here is a simple question for you, light photons allways have constant quantum of energy which we named 'h'( planck's constant). Then the mass of a photon is h/c². So why is it not increasing with velocity? At present no body can answer this, I'm pretty sure! Don't mistake me I'm polite to you all!

@@Italianjedi7 I never consider these gauge theories or string theory. Iam talking about the basic things of the universe he is dealing about. I'm worried about the great mistakes in our basic understanding.
