Dark matter played a significant role in the development of structures in the early universe. While it didn't directly become part of black holes or quasars, it did seed the development of galaxies.
To understand how dark matter affected the formation of structures, we need to delve into some astrophysics. Dark matter is a type of matter that does not emit, absorb, or reflect any electromagnetic radiation, making it invisible to telescopes. However, its presence can be inferred through its gravitational effects on visible matter, such as stars and galaxies.
In the early universe, dark matter began to clump together due to its gravitational attraction. These clumps, or dark matter halos, acted as gravitational wells, attracting and accumulating normal matter like gas and dust. Over time, these concentrations of normal matter within the dark matter halos began to cool, leading to the formation of nebulae, which are vast clouds of gas and dust.
Within these nebulae, gravity continued to bring more matter together, leading to the formation of protogalaxies. As these protogalaxies merged and collided, they eventually formed fully-fledged galaxies, including spiral, elliptical, and irregular types.
So, in summary, dark matter acted as the scaffolding upon which the cosmic web of structures formed. By providing the gravitational pull necessary to bring normal matter together, dark matter played a crucial role in seeding the development of galaxies. It affected the early universe by enabling the formation of structures like nebulae, which eventually evolved into the galaxies we observe today.
The correct answer is: It seeded the development of galaxies.
Dark matter is believed to have played a crucial role in the formation and development of structures in the early universe. It is thought that dark matter, which makes up a significant portion of the universe's mass, provided the gravitational pull necessary to attract and gather normal matter. Over time, this gravitational interaction led to the formation of galaxies, which are made up of stars, gas, and dust. Therefore, dark matter effectively seeded the development of galaxies in the early universe.
