Cosmology basics

: a branch of metaphysics that deals with the nature of the universe. b. : a theory or doctrine describing the natural order of the universe.
2: a branch of astronomy that deals with the origin, structure, and space-time relationships of the universe.
How do we study cosmology?
Observational cosmology studies the universe using telescopes and other equipment to examine the direct evidence of the universe's development and structure.
Physical cosmology studies the structures and development of the universe and the physics that created them..
What do you learn in cosmology?
Cosmology studies how the history of the universe led to the stars, galaxies, and other features we can observe today.
Cosmology is the study of the origin, development, structure, history, and future of the entire universe..
What is the basic knowledge of cosmology?
Cosmology studies how the history of the universe led to the stars, galaxies, and other features we can observe today.
Cosmology is the study of the origin, development, structure, history, and future of the entire universe.
In modern science, cosmology is divided into two branches..
What is the basic principle of cosmology?
The Cosmological Principle
It states: On the largest cosmic scales, the Universe is both homogeneous and isotropic.
Homogeneity means that there is no preferred location in the Universe.
That is, no matter where you are in the Universe, if you look at the Universe, it will look the same..
What is the basis for cosmology?
Modern physical cosmology is dominated by the Big Bang Theory which attempts to bring together observational astronomy and particle physics; more specifically, a standard parameterization of the Big Bang with dark matter and dark energy, known as the Lambda-CDM model..
To prepare yourself for this career, consider taking undergraduate courses in mathematics, science, philosophy and astronomy.
Majoring in astronomy may help prepare you for a career as a cosmologist, as it provides you with an introduction to many concepts and theories that are important in cosmology.

Cosmology is the study of the universe at large: its thermal and dynamical history, the origin and nature of its contents and structures on the largest scales. Our physical model of the universe, the “Hot Big Bang”, is motivated by fundamental physics and rooted in observational fact.

Cosmic Inflation

Around 13.8 billion years ago, the universe expanded faster than the speed of light for a fraction of a second, a period called cosmic inflation

Big Bang and Nucleosynthesis

When cosmic inflation stopped, the energy driving it transferred to matter and light – the big bang. One second after the big bang

Recombination

Around 380,000 years after the big bang, the universe had cooled enough that atomic nuclei could capture electrons

Dark Ages

After the cosmic microwave background

First Stars

Gas was not uniformly distributed throughout the universe. Cooler areas of space were lumpier, with denser clouds of gas. As these clumps grew more massive

Reionization

At first, starlight couldn’t travel far because it was scattered by the relatively dense gas surrounding the first stars. Gradually

The Future

For many years, scientists thought the universe’s current expansion was slowing down. But in fact, cosmic expansion is speeding up. In 1998
