I know this question sounds stupid but somehow i need confirmation I guess. Is it necessary to learn GR and SR to study cosmology ?
Yes ...berkeman said:What do you think?
So there is your answer.Arman777 said:Yes ...
GR and SR stand for General Relativity and Special Relativity, respectively. They are two theories proposed by Albert Einstein in the early 20th century to explain the behavior of gravity and the motion of objects in the universe.
GR and SR are essential for understanding the fundamental principles of the universe, such as the curvature of space-time and the relationship between matter and energy. These theories provide the foundation for modern cosmology and are used to explain the behavior of celestial objects and the evolution of the universe.
While there are other theories that attempt to explain the behavior of the universe, GR and SR have been extensively tested and have been shown to accurately describe the observations and data collected by astronomers and physicists. Therefore, it is necessary to learn these theories to have a comprehensive understanding of cosmology.
It is possible to study some aspects of cosmology without a deep understanding of GR and SR. However, to fully understand and contribute to the field of cosmology, it is necessary to have a strong foundation in these theories.
GR and SR are complex theories and require a strong background in physics and mathematics to fully grasp. It is recommended to take courses in general relativity and special relativity, as well as other related fields such as quantum mechanics and astrophysics. Reading textbooks and consulting with experts in the field can also aid in understanding these theories.
