In the show Loki (2021), the Time Variance Authority (TVA) is shown to be a massive city-like structure. However, there is no view of the outside world given from inside the TVA. Is there a canon answer as to where the TVA is located, in both time and space?
If not, is it feasible/possible that the TVA could be located in the Quantum Realm? We are told that "time passes differently here in the TVA" (Major Mobius M. Mobius, Loki S1E01 "Glorius Purpose"). In addition, it is revealed that time works differently in the Quantum Realm (making time travel possible for the Avengers in Endgame). Could this mean that the TVA is an infinitesimally small object in the Quantum Realm that can therefore avoid the proper flow of time? This is further evidenced by the fact that a version of Kang the Conqueror is the main antagonist of Ant-Man and the Wasp: Quantumania.
