The hypothesis states that during the formation of a star, the original nebula disk may be so massive that upon further contraction and flattening, it breaks into separate clouds (vortices) or protoplanets.

A hypothesis.
ANSWER: A verbal hypothesis is when you say a hypothesis orallly.
Hypothesis? Hypothesis is a proposal intended to explain certain facts or observations
when results from the experiments repeatedly fail to support the hypothesis.
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.
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.
No one was around at the time, so we're not really sure, but the current hypothesis in favor is called the "Giant Impact Hypothesis." It posits that a protoplanet about the same size as the current planet Mars struck the proto-Earth while it was still forming, and "splashed" a lot of rock off. This eventually formed the Moon, while the rest of this protoplanet (named Theia) joined with the Earth.

The protoplanet hypothesis originated from the need to explain the formation of planets in a systematic way, based on observations of protoplanetary disks around young stars. It suggests that dust and gas in these disks coalesce through processes like accretion and gravitational attraction, leading to the formation of larger bodies, or protoplanets. This hypothesis is supported by the laws of physics, including gravity and conservation of angular momentum, and aligns with the observed structure of our solar system and others. Ultimately, it provides a coherent framework for understanding the transition from dust clouds to planetary systems.
The three main theories on the origin of the Earth are the nebular hypothesis, the giant impact hypothesis, and the core accretion theory. The nebular hypothesis proposes that the solar system formed from a rotating cloud of dust and gas, while the giant impact hypothesis suggests that Earth formed from a collision between a Mars-sized protoplanet and the early Earth. The core accretion theory posits that planets formed from the gradual accumulation of solid particles in a protoplanetary disk.
An early collision by (proto) Earth with a large protoplanet..
A hypothesis
Yes, that is how Earth's formed, it hit a large protoplanet called Theia.
Currently, the most accepted theory is that it resulted from a crash between a large planetoid (or "protoplanet") and Earth.
There are several, but one of the more popular is that a protoplanet about the size of Mars originally shared Earth's orbit. It crashed into Earth, and threw off a gigantic cloud of debris that coalesced into the Moon. If you'd like to read more about this, look up "Theia", the name given to this hypothetical protoplanet.
The protoplanet underwent differentiation, where heat caused materials to separate based on their density. The heavy elements sank to the core, while lighter materials floated to the surface, forming layers. This process is important in planetary formation as it leads to the creation of distinct layers within a planet.
