The Science of Interstellar

Kip Thorne's work bridges science and film in a unique way. I'm curious what motivated him to make these ideas accessible to a wider audience.

The way the physics is broken down really enhances the wonder of space travel. Has this book changed how others view the scientific accuracy of Interstellar?

Thorne is a renowned physicist, but some concepts seem highly theoretical. I wonder how much of this is grounded in current science versus imaginative extrapolation.
