Explore our Theoretical Cosmology research
Theoretical cosmology is the study of the constituents and evolution of our Universe as a whole, from the earliest stages to the present day.
It involves building consistent theoretical models and testing their validity using data from experiments and observations..
A cosmologist is a scientist who uses space-based and ground-based telescopes and satellites to study the properties of the universe, including planets, black holes and galaxies.
They obtain data and observe certain aspects of astronomical objects, including distance, size, motion and brightness..
Cosmology can be a difficult discipline to get a handle on, as it is a field of study within physics that touches on many other areas. (Although, in truth, these days pretty much all fields of study within physics touch on many other areas.).
You would work in a laboratory or office, using a computer and remote controlled telescopes to observe the skies.
You might sometimes work in observatories, often based in other countries, as part of a team with astronomers from other countries.
You might work in a museum or planetarium open to the public..
Research in cosmology involves astronomy, but also gravitational physics, particle physics, and challenging questions about the interpretation of phenomena we can't see directly — such as the possible existence of something before the Big Bang..
Cosmologists study the large-scale structure and BAO to measure the rate of cosmic expansion and understand how galaxies are organized on the largest scales.
All the atoms in the universe only make up about 5% of its total contents.
The rest is dark matter and dark energy..
Cosmology deals with the physical situation that is the context in the large for human existence: the universe has such a nature that our life is possible.
This means that although it is a physical science, it is of particular importance in terms of its implications for human life.Sep 26, 2017.
Experimental astrophysics and cosmology research at Cornell can involve several areas of experimental physics, such as designing, building, and observing with new telescopes and cryogenic receivers, developing and testing superconducting devices, and analyzing data from observatories to help address questions about our universe
