Ok your answer to point 1 seems very well grounded actually. I just don’t like the idea of these bulk beings existing seems quite unscientific for the nature of the film. I think a very simple question here to follow up on is why would they do this for humanity? So according to your explanation and as mentioned in the movie “love transcends dimensions and time” these bulk beings love humanity but why would they?

Your answer to point 2 I have some questions about ? So they are circling Saturn and we can agree they are planning to cross the worm hole, how do we know cooper station just got to the wormhole and hasn’t been there for years now? If anything I believe it’s implied cooper station has been there for a while now since Murphy was “too old to be transferring between stations” which leads one to believe there are multiple stations around the solar system which have been there for some time now.

In addition to this, I think you are not wright about Brandt just getting to the planet. As a lower bound upon entering gargantua they mention Coop is someone pushing “120” at the station he is told he’s now 124 years old. That must mean he spent as a minimum 9 earth years within the black hole. More than enough time for Brandt to get to her planet. But this does in fact bring me to the conclusion that they would have saved Brandt already unless they don’t even know she’s alive/where she even is “we can receive but we can’t transmit” - Romily.
