Was our sun formed first, and then the planets around the sun were formed by the strong gravity of the sun from galaxies and dying stars, or did the sun and the planets of the solar system form at the same time, and is Laplace's theory correct or not? ?

As you know, in the beginning, Laplace's theory says that a hot mass with hot rings formed around the star, and the rings gradually turned into planets, and the ones that were close to them became rocky, and the distant planets turned into gas planets. But later, the views of the formation of the planets of the solar system changed and were divided into 3 categories. One is the theory of the ring, which was confirmed by Laplace, and the second was the theory of the nebula, which was formed by Govich's star, and due to the gravity and power of the star, from the death of a star and the dust inside the orchids, this nebula around our star is They formed the sun, and over time, those that were close to the sun became rocky planets, and those that were far from the sun, gas planets. Of course, the grief of each of the planets of the solar system can be studied separately, why, for example, the soil of Mars is red and why it has so many volcanoes, or the planet Saturn, which is the bride of the solar system; Why is there a ring of ice, rock and poisonous gases, or why is it on the planet Jupiter? Why do very violent storms happen and the big eye of Jupiter is very powerful and the speed of the storms of this huge planet which has the largest mass in the solar system after the sun and why it has so much gravity and a huge magnetism that about 62 moons around it becomes Now, the new opinions about the sun, which says that the galaxy is like a lion, which has 5 branches of the Milky Way galaxy, which, according to astronomers, is due to the gravitational force of the galaxy that has swallowed the smaller galaxy, and that smaller galaxy around this galaxy causes formed the branches of this galaxy. This universe with so many stars and planets and small galaxies is like the oceans of the earth that catch big fish and small fish. It is the same in the universe that big stars can catch small stars around. attract themselves, for example, create binary stars, and large galaxies can merge their smaller galaxies inside themselves.

you can find out answer of this question by analysing first that which event in space time or in system form more symtrical pattern whether the formation of sun or planets,

the one event which form more symmetrical pattern in universe will take pla ce first.

They formed at the same time, from the protosolar nebula.

Laplace's theory is over 2 centuries old...historically interesting, but superceded by more complete physics and far more detailed models run on high performance computers. Observations (by ALMA, JWST, and 8-10m telescopes with adaptive optics) confirm that these simulations are substantially correct, with disks, rings and compact sources detected. I advise you to read recent research papers on solar system formation, and exoplanetary system observations at high resolution.

Planetary systems like the solar system are assumptions developed from the relative positions of central and orbiting bodies. Nobody can remain in space without translation.

It is physically impossible for a free macro body to revolve around another moving body in any type of geometrically closed path. This can be observed by watching someone trying to move around another person running along a defined path. Planets are free macro bodies, the central body (sun) is a moving body and the circular/elliptical path is a geometrically closed path.

Therefore, all cosmic bodies are independent and each one is formed separately from other bodies. All nearby bodies in space are grouped together by us as a closed system with the largest body assumed static in space.

Stages of formation of the solar system:

1- In the sun, the inner core and the outer core are formed simultaneously.

2- The sun consists only of the inner core and the outer core.

3- The Sun's crust: the first Kuiper layer that is placed on the Sun's core.

Important note: the shell of the star and the sun is not part of the stars and the sun. After the formation of the core: the shell particles are poured on the core in the form of layers and plates.

After the formation of the sun: the planets are formed.

Complete explanations and their proof with mathematical and classical formulas soon..

I discovered the description of the formation of the core of the star from the moment of subzero to the moment of death.
