1. Dark matter
Dark matter is a mysterious and poorly understood substance that is thought to make up about 85% of the matter in the universe. It is invisible to telescopes and does not interact with light or other forms of electromagnetic radiation. Despite this, dark matter has a gravitational pull, which can be seen in the way that galaxies rotate.
- Evidence for dark matter
The existence of dark matter is inferred from its gravitational effects. One of the most convincing pieces of evidence for dark matter is the rotation of galaxies. Galaxies rotate much faster than they should if they were made up only of the visible matter that we can see. This suggests that there must be a large amount of unseen matter, or dark matter, that is providing the extra gravity needed to keep the galaxies rotating.
- Properties of dark matter
Dark matter is thought to be cold and collisionless. This means that it does not interact with itself or with other forms of matter very much. Dark matter is also thought to be distributed throughout the universe in a halo around galaxies.

3. Early universe
The early universe is the period of time from the Big Bang to the formation of the first stars and galaxies. It is a period of intense activity and change, during which the universe expanded and cooled, and the first structures began to form.
- The Big Bang
The Big Bang is the scientific theory for the origin and evolution of the universe. It states that the universe began about 13.8 billion years ago with a very hot, dense state. This state then expanded and cooled, forming the universe that we see today.
- Inflation
Inflation is a period of rapid expansion that occurred in the early universe. It is thought to have occurred between 10^-36 and 10^-32 seconds after the Big Bang. During this period, the universe expanded by a factor of at least 10^26.
- Cosmic microwave background
The cosmic microwave background (CMB) is the leftover radiation from the Big Bang. It is a faint glow of light that fills the entire universe. The CMB is one of the most important pieces of evidence for the Big Bang theory.
- Structure formation
Structure formation is the process by which the first stars and galaxies formed. It is thought that the first stars formed about 100 million years after the Big Bang. These stars then merged to form the first galaxies.

4. Cosmology
Cosmology is the study of the universe as a whole, including its origin, evolution, and ultimate fate. It is a branch of astrophysics that deals with the largest scales in the universe, from the smallest galaxies to the largest superclusters.
- The Big Bang
The Big Bang is the leading scientific theory for the origin of the universe. It states that the universe began about 13.8 billion years ago with a very hot, dense state. This state then expanded and cooled, forming the universe that we see today.
- Dark matter and dark energy
Dark matter and dark energy are two of the most mysterious and poorly understood phenomena in the universe. Dark matter is a type of matter that does not interact with light or other forms of electromagnetic radiation. Dark energy is a hypothetical form of energy that is believed to be responsible for the observed acceleration of the universe's expansion.
- The formation and evolution of galaxies
Galaxies are the largest gravitationally bound structures in the universe. They are made up of stars, gas, and dust. Galaxies form and evolve over time through a process called hierarchical growth.
- The future of the universe
The future of the universe is uncertain. It is possible that the universe will continue to expand forever, or it may eventually collapse back in on itself. The fate of the universe depends on the amount and type of dark energy in the universe.
