Astronomers observe as much as they can and collect enormous amounts of information based upon the radiation in various spectra, both visible and invisible, from stars, galaxies, interstellar gas clouds, and anything else they can see in the night sky, and they then perform very intricate and sophisticated mathematical analyses of the data in order to obtain reasonable theories.
Gas and radiation flowing away from a newly formed massive star can blow away nearby gas and dust forming star formation pillars. Where nearby gas and dust clouds are compressed, new star formations can be triggered.
The nebula theory, also known as the solar nebula theory, is widely accepted in the scientific community because it provides a well-supported explanation for the formation of the solar system. Evidence such as the composition of planets and their moons, the orbits of planets, and the presence of asteroids and comets all support this theory. Additionally, observations of other star systems have shown similar processes at work in forming planets.
The main difference between the nebular and condensation theories is their emphasis on different aspects of planet formation. Nebular theory focuses on the collapse of a rotating nebula to form a star and planets, while condensation theory emphasizes the role of solid particles (dust and gas) in the early stages of planet formation.
Lots of things do NOT happen. Better read an article on star formation and find out what DOES happen.

The Nebula Cloud theory is more widely accepted and supported by evidence compared to the Passing Star theory. The Nebula Cloud theory suggests that stars form within nebulas, while the Passing Star theory proposes that stars are formed by interactions with other stars.
Two primary theories explain how the spiral arms of galaxies are maintained: the density wave theory and the self-propagating star formation theory. The density wave theory posits that spiral arms are not made up of material but are instead regions of higher density that rotate around the galaxy, causing stars and gas to cluster and create the appearance of arms. The self-propagating star formation theory suggests that star formation occurs in waves, where the formation of new stars triggers further star formation in adjacent areas, leading to the development of spiral patterns over time. Both theories highlight the dynamic processes that contribute to the structure of spiral galaxies.

I think you mean the steady state theory. This is the idea that new matter is constantly being created as the universe expands. We now have evidence that the big bang theory is a far more likely one.

Star Wars Movies do not affect the formation of magma.
We know not. The existence of Nemesis is a hypothesis - a possible explanation for a perceived regularity in mass extinctions in the past. it has neither been confirmed, nor is there sufficient evidence to discard the possibility of such a star.
Well, if you look at it from space, like from telescopes you can notice the form of the milkyway is a spril looking, star formation.
Find The Plough constellation (big dipper) - on the 'bowl' of the formation - follow a line up from the two stars at the end, and the first star you come to in a direct line is the North Star.
Not exactly: Star formation is believed to be a slow process, compared to a human lifetime; scientists have, however, seen stars in different phases of their formation.
There is a lot of speculation about this; some believe it may have been a Nova star or Supernova; others favour the theory that it was a planetary alignment which might have appeared like a very bright star. Another possibility was that it was actually a comet.There is no firm evidence for any of these theories.
