In an earlier blog post about Christopher Nolan’s latest blockbuster movie, Interstellar, I lauded the film for its ambition, its visuals     and the strong performances of its cast. However, I also criticized it for its depiction of interstellar travel and a plot filled with details that didn’t seem to make much sense.

Perhaps because I called some of its science “laughably wrong,” my post drew the attention of Kip Thorne, the Caltech physicist who served as science advisor on the film. Thorne sent me a copy of his new book, The Science of Interstellar, and encouraged me to read it and reconsider my criticisms. The book tells the story behind the film’s creation, and provides deep, thorough explanations for many facets of Interstellar that might otherwise seem nonsensical.

Thorne is even-handed in his treatment of the film’s science, admitting where artistic license was substantial and where it was used barely at all. If you enjoyed the film, but found parts of it confusing or puzzling, The Science of Interstellar and the perspectives it provides might be for you.
