Imagine there is no EM or Nuclear Force, and Gravity is the only force.
Can gravity alone produce an atomic structure similar to a basic atom?
In this scenario, the nucleus is just a single particle. The electron is another particle with only mass and angular momentum, like a planet orbiting a star.
How feasible is it for Gravity alone to produce such a structure and hold it together, with energy and mass equivelent to those of simple hydrogen nuclei, electrons and matching speed/energy of orbits and angular momentum
