I was on Youtube the other day and found a series of videos that explain the four fundamental forces in terms of a basic particle called the kaon. I basically understood the first 13 videos, but at video 14 I was lost. In the first few videos, they explain gravity, basically stating that it is...

I'm very fascinated on both things. I want to study Black Holes, Dark Matter and Dark Energy. Stuff like that in the big world of Astrophysics, but I'm also very attracted to particle physics with the ways forces works on atomic scale, and how elementary particles work. I really have a hard time...

Hello; I'am asking about the best textbook or refrence in particle & high energy physics ?

Ok. So I literally just created this account, but I need to ask you all something. I'm a junior in undergraduate college. I am pursuing a double major in English-Literature, and Philosophy. I have always been interested in physics, specifically astronomy, astrophysics, particle physics, etc...

I'm a senior undergrad and will be applying to grad school soon. The field I'm interested in is experimental high-energy physics. There are already about six schools I'm looking at applying to, but I'm wondering if anyone has any advice about possible safety schools. My overall GPA is about...

True Background-Independent String Theory/Particle Physics Lee Smolin mentions in Trouble with Physics: "... it is not enough to have a theory with gravitons made from strings wiggling in space. We need a theory about what makes up space, a background-independent theory. As described...

And are reactions in particle physics reversible at all? If so, why don't we ever see Gibbs free energy used in particle physics equations?

Hello! I have difficulty trying with the interpretation of: (\frac{1}{2}) \otimes (\frac{1}{2}) \otimes (\frac{1}{2}) = (\frac{3}{2}) \otimes (\frac{1}{2}) \otimes (\frac{1}{2}) If I´m right this is the SU(2) irrep for isospin but what does this mean? Proton = Neutron?

Special Relativity is just a special case where spacetime is flat and fixed. Meaning it is not really a correct picture of reality because nature chooses curved spacetime that is background independent. So quantum particles shouldn't be occurring in a flat fixed background but a dynamic...
