Which is the superior power: Gravity or Electromagnetic force?

Consider the act of combing your hair: the tiny amount of static charge that accumulates on the comb is sufficient to lift your hair upwards against the force of an entire planet's gravity. The electromagnetic force is approximately 20 orders of magnitude more powerful than gravity.

There is an upper limit to electromagnetic force, though, in that charged objects repel like-charged objects and attract other (oppositely) charged objects, which neutralizes them. For instance, if you tried to jam too many electrons into a jar, the jar would eventually discharge violently due to the mutual repulsion of the electrons and the attraction of nearby positive objects.

However, since everything that has mass attracts other objects that also have mass, there isn't really a limit to how big a mass can get. In fact, the more mass there is, the stronger the gravity. Supermassive black holes exist that are millions of times more massive than the sun.

Because of this, even though gravity is the weaker of the two forces, it can act over large distances and is dominant at the astronomical scale (galaxies can be gravitationally bound to other galaxies millions of light years away).

Both gravity and electromagnetic force are fundamental forces in nature, but their effects are different and cannot be directly compared in terms of superiority. Gravity is responsible for the attraction between masses, while electromagnetic force governs interactions between charged particles. Each force plays a crucial role in different phenomena, and their significance depends on the context in which they are being considered.
