The Big Bang theory is the scientific explanation for the origin of the universe approximately 13.8 billion years ago. It describes the rapid expansion of space and the subsequent cooling and formation of matter. The solar system formed about 4.6 billion years ago from a rotating disk of gas and dust in space, with the Sun at its center and planets and other celestial bodies forming from the material in the disk through a process called accretion.
Catastrophic theory of the solar system suggests that major disruptions or events in the past, such as collisions or close encounters with other celestial bodies, played a significant role in shaping the current structure of our solar system. This theory contrasts with the gradual, slow processes of traditional solar system formation theories.
The Nebula Theory is also known as the Solar Nebula Theory. It is a widely accepted model for the formation of our solar system.
A leading theory for the formation of comets and asteroids is the solar nebula theory, which posits that these bodies formed from the residual material left over after the formation of the Sun. As the solar system developed, dust and gas in the protoplanetary disk coalesced into larger objects. In the colder outer regions of the disk, ices and volatile compounds accumulated, leading to the formation of comets, while the inner regions, where temperatures were higher, favored the formation of rocky and metallic bodies, resulting in asteroids. This process occurred during the early stages of the solar system's evolution, around 4.6 billion years ago.
The key ingredient in the modern condensation theory that was missing in the nebula theory is the understanding of the role of turbulence. Condensation theory incorporates the effects of turbulence in the early solar system, showing how it can facilitate the collapse of material into the Sun and the formation of planetesimals. This provides a more detailed and realistic explanation for the formation of the solar system compared to the original nebula theory.
The three theories of the formation of the solar system are the nebular theory, the planetesimal hypothesis, and the gravitational instability theory. The nebular theory proposes that the solar system formed from a rotating disk of dust and gas, while the planetesimal hypothesis suggests that small, solid bodies collided and accreted to form planets. The gravitational instability theory proposes that clumps of material in a protoplanetary disk collapsed under their gravity to form planets.

The solar nebula theory is considered a theory rather than a hypothesis because it is a well-substantiated explanation supported by a substantial body of evidence from various fields, including astronomy, geology, and physics. It provides a comprehensive framework for understanding the formation and evolution of the solar system, incorporating observations of protoplanetary disks and the distribution of elements in the solar system. Unlike a hypothesis, which is a testable prediction or assumption, a theory is a robust explanation that has withstood extensive testing and scrutiny over time.
The nebular hypothesis is the most widely accepted model explaining the formation and evolution of the Solar System.

The dust cloud theory, which suggests that the solar system formed from a rotating disk of gas and dust, was proposed by Russian astrophysicist Viktor Safronov in the 1960s. He published his ideas in his book "Evolution of the Protoplanetary Cloud and Formation of the Earth and Planets."

The theory of the asteroid belt is - it was another planet that failed to 'gel' properly at the time the solar system was being created.
Not exactly, it is a theory about the origin of the Universe; which does include the Solar system...
The term that best describes how the solar system was formed is "solar nebula theory." This theory suggests that the solar system originated from a rotating cloud of gas and dust, known as a solar nebula. Under the influence of gravity, this cloud collapsed, leading to the formation of the Sun at its center and the planets, moons, and other celestial bodies from the remaining material.
