With the 4 elementary interactions, gravitation is definitely the dominant at astronomical duration scales. Gravity's outcomes are cumulative; Against this, the results of optimistic and detrimental fees tend to terminate each other, producing electromagnetism fairly insignificant on astronomical duration scales.
