The Science of Interstellar

Kip Thorne wrote the science of interstellar, which is probably even easier to read and understand. It would be very difficult if you just picked up a textbook, which isn't really intended for people who don't have a very specific preparation with it. You know, all this stuff is much easier than just picking up random microeconomics textbook or something because sometimes that's very specific in how it doesn't try to explain things.
