The primary sources of heat for protoplanets during their formation were gravitational collapse, radioactive decay of elements within the planet, and impacts from other celestial bodies. These heat sources contributed to melting the protoplanet's interior and driving geological processes like differentiation and magma ocean formation.

The protoplanet hypothesis describes the formation of planets from the dust and gas present in the early solar system. It suggests that small planetesimals collided and merged to form larger celestial bodies, eventually leading to the creation of the planets we see today.
Both the nebular hypothesis and the protoplanet hypothesis describe the formation of the solar system from a rotating cloud of gas and dust. The nebular hypothesis suggests that this cloud, or nebula, collapsed under its own gravity to form the Sun and planets, while the protoplanet hypothesis specifically focuses on how solid materials within the nebula coalesced to form planetesimals and eventually protoplanets. Both theories emphasize the role of gravitational forces and accretion processes in the development of celestial bodies. Ultimately, they aim to explain the origin and structure of the solar system.
The protoplanet theory, which explains the formation of planets from a rotating disk of gas and dust surrounding a young star, was developed through the contributions of several scientists. Key figures include the physicist Carl Friedrich von Weizsäcker and later improvements by others such as Steven J. Desch. This theory evolved from earlier models of planetary formation and has been refined through observations and simulations of protoplanetary disks.

I think you mean "protoplanet hypothesis". In fact, astronomers usually call it the Nebular Hypothesis A protoplanet is a planet-like object that hasn't fully developed into a planet. Why that hypothesis? It's because it is the best we have to describe the origin of the solar system according to the Laws of Physics.
Because they just happened to sign players that were all dark skined!
