The third and final installment of the CuriosityStream series "Stephen Hawking's Favorite Places" was released after Hawking's death last week and can be streamed online for free through this Friday.

The final episode deals with some of the more speculative Hawking ideas, like his search for a "theory of everything" that led to his belief that our universe is but one of an infinite number of universes popping in and out of existence like bubbles, all floating around within the so-called multiverse.
