From the post "Temperature, Space Density And Gravity",
If an electron collide into the nucleus,
\(r_o=\cfrac{q^2}{4\pi \varepsilon_o{m_ec^2}}<r_{n}\)
where \(r_{n}\) is the radius of the positive nucleus.
We see that as \(c\) increases in less dense space \(r_o\), the orbital radius of electron decreases and it might clash into the nucleus and annihilate with a positive charge there in a matter/antimatter fashion.
This suggests that heavier elements of larger \(r_n\), nucleus radius, is less stable from such possible collisions. It also suggest that if we are able to pump space into a containment and make space inside denser (\(c\) decreases), heavy elements in it will be more stable.
And oddly, in denser space, atoms are larger because of greater electron orbits.
