Dark matter played a crucial role in shaping the development of structures in the early universe. Although it does not interact with light and remains invisible, its gravitational influence was significant.
One of the primary effects of dark matter was the gravitational attraction it exerted on regular matter, such as gas and dust. The gravitational pull of dark matter caused denser regions of gas to gather and form what are known as dark matter halos. These halos served as a gravitational scaffolding for the development of galaxies.
By pulling in and concentrating gas and dust particles, dark matter halos provided the necessary conditions for galaxies to form. As the gas and dust collected in these regions, it eventually cooled down and condensed to form nebulae. These nebulae then collapsed under their own gravity, giving birth to stars and galaxies.
Dark matter also played a role in the formation of supermassive black holes. As galaxies formed within dark matter halos, the central regions became denser and eventually collapsed, forming black holes. Dark matter played a significant role in providing the gravitational forces necessary for the formation of these black holes.
Regarding quasars, while they are powered by supermassive black holes, the specific influence of dark matter in their development is not well understood. However, it is believed that dark matter may have played a role in the early phases of quasar formation by providing the necessary conditions for the formation of the supermassive black hole that powers them.

Apologies for the repeated response. To clarify, dark matter affected the development of structures in the early universe by seeding the development of galaxies, cooling pockets of gas to form nebulae, and becoming part of black holes. It is not well understood how exactly dark matter specifically influenced the development of quasars.

Apologies for the confusion caused by the repeated response. The two correct answers are:
1. The percentage of dark energy has grown in scientists' estimates since the 1970s. The discovery and subsequent research on the accelerating expansion of the universe led to the introduction of the concept of dark energy, a mysterious force believed to be responsible for this acceleration. As a result, the percentage of dark energy in the composition of the universe has increased in scientists' estimates.
2. The percentage of unknown material has shrunk in scientists' estimates since the 1980s. With advancements in observational techniques and theoretical modeling, scientists have gained a better understanding of the composition of the universe. As a result, the percentage of previously unknown material (such as dark matter) has decreased as scientists have been able to detect and quantify its presence.
