Theoretical physicist and futurist Michio Kaku, who writes the Dr. Kaku's Universe blog for Big Think, is appearing on Comedy Central's "The Colbert Report" tonight at 11:30 to talk about "strings, quantum theory, the multiverse and more."

Dr. Kaku's recent posts for Big Think have focused on whether learning from nature might help us create a "replicator" in a lab; why physicists "are the only scientists who can say the word 'God' and not blush"; and the basics of string theory.
