Interstellar the movie and real physics

[Duhoc]

Just viewed the new flick. I'm guessing the author of the novel upon which the movie was based was a physicist and that the story is consistent with known physics. So, I thought I might get a few details straight. In the movie there is no "them" no other beings other than humans who are helping the humans. Apparently, entering the black hole gave the astronaut access to the past and future. Maybe not. Certainly the past. But how was he able to enter the black hole without being turned into spaghetti? How was he able to communicate with the robot once he was inside the black hole since the laws of physics no longer work? What was the organizational structure he encountered there? Who made that? How was he able to transmit the data through the watch? Did Boltzman brains play a roll in this?

The film sure is generating a lot of discussion. Have a look at this thread here:

It's probably the best place to keep the discussion focused.
