What exactly is the difference? The latter does not seem so popular to me? On average how much does the latter earn?
Theoretical physics is a branch of physics that uses mathematical models and theories to explain and predict the behavior of physical systems. It focuses on understanding the fundamental laws and principles of nature, such as quantum mechanics and relativity. Theoretical cosmology, on the other hand, is a subfield of theoretical physics that specifically studies the origin, evolution, and structure of the universe as a whole.
The main areas of study in theoretical physics include classical mechanics, electromagnetism, quantum mechanics, and relativity. These theories are used to explain and understand a wide range of physical phenomena, from the behavior of subatomic particles to the motion of planets and galaxies.
Theoretical physics plays a crucial role in our understanding of the universe. By using mathematical models and theories, theoretical physicists are able to make predictions about the behavior of the universe and test them through experiments and observations. This allows us to uncover the fundamental laws that govern the universe and gain a deeper understanding of its origins and evolution.
Some current topics of research in theoretical cosmology include the study of dark matter and dark energy, the origins and properties of the cosmic microwave background radiation, and the evolution of the large-scale structure of the universe. Other areas of interest include the search for a theory of quantum gravity and the study of the multiverse hypothesis.
Theoretical physics has been instrumental in the development of many modern technologies. For example, the theories of electromagnetism have led to the invention of devices such as radios, televisions, and computers. The understanding of quantum mechanics has also led to the development of technologies such as transistors, lasers, and GPS systems. Theoretical physics continues to drive technological advancements by providing a deeper understanding of the fundamental principles of nature.
