1. Galactic Cosmic Rays (gcrs)

   Linked via "Beryllium"

   Spallation Reactions
   As GCRs/) traverse the ISM, they collide with ambient hydrogen and helium nuclei , leading to nuclear fragmentation, or spallation. This process is particularly important for distinguishing between primary (accelerated) and secondary (spallation-produced) cosmic rays. Notably, the abundance ratio of Lithium, Beryllium, …

2. Proton Proton Chain

   Linked via "beryllium"

   $$^7\text{Li} + ^1\text{H} \rightarrow 2^4\text{He}$$
   This branch is responsible for a measurable component of the solar neutrino flux, specifically those neutrinos arising from the $^7\text{Be}$ decay stage. The cross-section for this pathway is strongly dependent on the atomic mass ratio of beryllium to lithium within the stellar plasma/) [1].

3. Weak Equivalence Principle

   Linked via "beryllium"

   Early, highly precise tests were developed by Loránd Eötvös in the late 19th century. These experiments utilized a torsion balance comparing the gravitational attraction exerted by the Earth on two different masses ($mA$ and $mB$) against the effect of the centrifugal force due to the Earth's rotation. The Eötvös number ($\eta$) quantifies any violation of the WEP:
   $$\eta = 2 \frac{(mg/mi)A - (mg/mi)B}{(mg/mi)_A + (…
