There is no specific law for the birth of the solar system. The formation of our solar system is explained by scientific theories, primarily the nebular hypothesis, which suggests that the sun and planets formed from a rotating disk of gas and dust. This process took place over billions of years.
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.

According to the nebular hypothesis, our solar system formed from a huge rotating cloud made mostly of hydrogen and helium gas, with trace amounts of heavier elements. The cloud, or nebula, slowly collapsed under its own gravity, leading to the formation of the sun and the planets.
The nebular hypothesis posits that our solar system formed from a large rotating cloud of dust and gas composed mostly of hydrogen and helium, leftover from previous supernova explosions. Over time, gravity caused the cloud to collapse and form a protostar at its center, with a surrounding disk from which planets eventually coalesced.
The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from nebulous material.
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.
The most widely accepted model for the formation of the solar system is the nebular hypothesis. This theory suggests that the solar system formed from a rotating mass of gas and dust known as the solar nebula, which collapsed under its own gravity to form the Sun and surrounding planets approximately 4.6 billion years ago.
The hypothesis on how the solar system was formed is known as the solar nebula theory. This theory posits that the solar system formed from a massive, rotating cloud of gas and dust called the solar nebula. Over time, gravity caused the material in the nebula to clump together, eventually forming the sun and the planets.
The nebular hypothesis attempts to explain the formation and evolution of the solar system. It posits that the solar system formed from a rotating cloud of gas and dust, known as a solar nebula, which collapsed under its own gravity. As the nebula contracted, it spun faster, flattening into a disk and eventually leading to the formation of the Sun at its center and the planets from the remaining material. This hypothesis addresses the structure and dynamics of planetary systems and their development over time.
It was first proposed in 1734 by Emanuel Swedenborg. Originally applied only to our own Solar System, this method of planetary system formation is now thought to be at work throughout the universe. The widely accepted modern variant of the nebular hypothesis is Solar Nebular Disk Model (SNDM) or simply Solar Nebular Model.
