AI Thread Summary
Grand Unified Theory (GUT) involves various symmetries, notably U(1) and SU(2), which play crucial roles in particle physics. Understanding these symmetries requires a grasp of gauge theory, often covered in quantum field theory (QFT) literature. A recommended resource for beginners is a specific online lecture that simplifies the concepts of GUT and symmetry. This presentation is considered accessible for those new to the subject. Exploring these resources can enhance comprehension of the evolution and significance of symmetries in GUT.

Hello,

I am quiet new to this subject. I am reading over grand unified theory and found that there are quiet a number of Symmetries, like U(1) and SU(2).....

Can anybody help me in finding all the types of symmetries and how it evolved and what are they basically are?

Thanks

Look for 'gauge theory' in any good qft book, or just google it.
 
I'm a layman (sadly). I found a pretty neat site that may help you.

I'm wondering what the community thinks about this presentation. Its one of the best (I think) that I've found for dumb guys. :)

You can pan back and forth with "Forward" and "Back" buttons at the bottom of each lecture. GUT and symetry is explained:

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
