The discussion revolves around the categorization of Quantum Gravity and Cosmology within the branches of physics. Participants explore whether these subjects belong to astrophysics, relativity, quantum mechanics, classical mechanics, or other categories, while also addressing the implications of such classifications for studying these topics.
Participants express differing views on the categorization of Quantum Gravity and Cosmology, with no consensus reached on their classification within the branches of physics. The discussion remains unresolved regarding the necessity and implications of such categorization.
Participants highlight the need for a solid grounding in multiple foundational areas of physics before studying Quantum Gravity and Cosmology, indicating that the discussion may depend on individual educational paths and definitions of branches.
i know that those 2 subjects are not in the same branch but i want to leanr more about quantum gravity and more about cosmology (those are 2 different subjects) and first i have to determine those 2 in which branch they areVanadium 50 said:What is this obsession with categorization? And why do you think two different subjects are necessarily in the same branch?
Why?Peter25samaha said:first i have to determine those 2 in which branch they are
i have some branches i want to do i want to know Cosmology and Quantum gravity in which one they are (i mean each one .. in which branch)Nugatory said:Why?

No i don't mean that . I mean in which branch we study cosmology and quantum gravitysecur said:I think OP simply means which Physics Forum to use when posting questions about Quantum Gravity - particularly relating to Cosmology? Could be "Quantum Physics" or "Special and General Relativity" or "Cosmology". I'd try the latter
and see what happens, if nothing, try the others.
If you want to study quantum gravity or cosmology... Then you study quantum gravity or cosmology. You will not be in a position to study either topic until have a solid grounding in all the foundational areas of physics: quantum mechanics, special and general relativity, classical mechanics, statistical mechanics. Thus, it's silly to ask which "branch" you need - you need them all.Peter25samaha said:No i don't mean that . I mean in which branch we study cosmology and quantum gravity
Yeh i think this is good i need all of them . But electricity , i think that i don't need it in all of that quantum physics ,gravity , darke energy and matter , black holes . Should i learn electricity branch in these things ?Nugatory said:If you want to study quantum gravity or cosmology... Then you study quantum gravity or cosmology.

- Translation web sites, like Google translate, are useful. When needing to post in another language, first I translate my English to that language; then, translate it back. Change garbled phrases, try again. When it comes back making sense I figure it's good to go. With a little practice you learn how to phrase things simply; and, reading the translation helps me pick up the other language.Peter25samaha said:English is my third language its for that
