Of the four fundamental forces in nature only three – the electromagnetic force and the strong and weak nuclear forces – are explained by the #StandardModel of #ParticlePhysics.
The model can't explain the fourth fundamental force, #gravity, or #DarkMatter – a strange and mysterious substance thought to make up about 27% of the universe.

2/ As I began to get into theoretical physics back in 2013, as I began reading about the #StandardModel, I found that the descriptions of the relationships between the fundamentical particles formed a sort of "representational model" in my mind's-eye, and I was able to see (and even hear(!) more on that later) the details of the interactions between them.
At first, my pictures were wrong, and the questions I asked were also wrong.
However, over time, learning more, the pictures clarified. 2/

Big #News, #ICYMI: Recent measurements of rare B-meson decays using data from the entire #LHC Run 1 and 2 support the predictions of the #StandardModel, effectively replacing earlier findings that suggested deviations from the long-standing theory.

#Axions have a double motivation: they solve the 'strong CP problem' of the #StandardModel of elementary #Particles & they are a candidate for the #DarkMatter of the #Universe. The discovery of axions would answer many questions about dark matter & other #ParticlePhysics mysteries. Axions are also predicted by #StringTheory, or the idea that all the forces & particles in the universe are tied together as part of the same framework.
