Ever wondered what's beyond our universe?  So did Dr. Michio Kaku, beginning at the young age of 8, and it led him to try and complete Einstein's unfinished work: a theory of everything.  Dr. Kaku is a world-renowned physicist and a co-author of String Field Theory,  which some claim is the closest we've come to understanding the code of the universe.  In our fascinating conversation, Dr. Kaku and I explore multiverses, measure consciousness, and question the nature of reality...and cats.
