'Interstellar,' the new science fiction film, is rightly praised for its adherence to the real science of black holes, wormholes, extra dimensions and time travel. Moreover, promoting frontier concepts of cosmology builds public appreciation of real science. Successful entertainment need not be all escapist and unscientific like, say, magic ('Harry Potter') and fantasy ('Transformers,' 'X-men').
It goes deeper. Can grasping the exotic nature of reality approach bigger issues of meaning and purpose (if there be any)? What's it all about? Perhaps the philosophy of 'Interstellar,' as well as its science, is worth exploring.
