It has been said that electromagnetic force attracts electrons and protons to one another, while planets and celestial objects are attracted to each other by gravity. A fundamental property of matter is that matter attracts other matter to itself. If this is true, then why do we consider the electromagnetic force and gravitational force to be so different? I understand the internal energies are hugely different between atomic bodies & celestial bodies, but they are both composed of matter. Any thoughts are welcome. Thanks in advance.
