Although it is possible that you may spend some of your time looking through a telescope, this isn't very common for a cosmologist.
Instead, they work with data collected by others, usually on computers, analyzing it, while exploring and testing theories..
A key part of this comes from observations of the cosmic microwave background, which contains the afterglow of light and radiation left over from the Big Bang.
This relic of the Big Bang pervades the universe and is visible to microwave detectors, which allows scientists to piece together clues of the early universe..
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..
Obtain a Ph.
D. in a related field like physics, mathematics or astronomy.
Work as a cosmologist relies on adequate knowledge in all three fields.
This profession uses advanced mathematics like algebra and calculus, so consider focusing on these areas while in a graduate program..
Anaximander of Miletus was one of the first philosophers in the ancient Greek world to develop theories on natural sciences..
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..
Cosmology is a branch of science which studies the evolution of our universe.
A scientist who studies cosmology is called a cosmologist.
Cosmologists want to know what the universe was like billions of years ago.
They want to understand how it is today..
Hawking was one of the most well-known scientists of the late 20th and early 21st centuries, recognized for his work on black holes, his efforts to communicate complex cosmology to the general public and a sense of humor said to be "as vast as the universe.".
• Tom Abel (1970–) studied primordial star
• Ja'far ibn Muhammad Abu Ma'shar al-Balkhi (787–886) conveyed Aristotle's theories from Persia to
• Bernard J. Carr (1949–) promoted the anthropic principle
• Paul Davies(1946–) developed a vacuum model that explains microwave background fluctuation, studies time's arrow
• George Efstathiou(Cosmologist) (1955–) pioneering computer simulations
Astronomy - Cosmology, Universe, Stars: Cosmology is the scientific study of the universe as a unified whole, from its earliest moments through its evolution to its ultimate fate
The currently accepted cosmological model is the big bang
In this picture, the expansion of the universe started in an intense explosion 13
