> Is Gravity just a by product of Electromagnetic Force

No, they are completely different things.

If you make something float then you exert an electromagnetic force upwards that's as strong as the gravitational force downwards, leading to a net force of zero. The same applies for e.g. things resting on a table, it's just easier to get it balanced there.

> Everything emits electromagnetic waves

Uncharged particles do not, and very cold objects have negligible emissions.

> everything is impacted by Gravity

... even uncharged particles, and it's essentially independent of temperature.

> If both forces protrude "forever" and become their strongest at a certain "break point"

There is no "break point".

An 1/R^2 law is the natural relation in 3 dimensions as the surface area of a sphere scales with R^(2). Deviations from that relation are special (they need massive exchange particles, for the weak interaction, or strong self-interaction, for gluons).
