Popular science
Kaku is most widely known as a popularizer of science
and
physics outreach specialist. He has written books and appeared on many television programs as well as film. He also hosts a weekly radio program.
Radio
Kaku is the host of the weekly one-hour radio program ''Exploration'', produced by the Pacifica Foundation's
WBAI in New York. ''Exploration'' is syndicated to community and independent radio stations and makes previous broadcasts available on the program's website. Kaku defines the show as dealing with the general topics of science, war, peace, and the environment.
In April 2006, Kaku began broadcasting ''Science Fantastic'' on 90 commercial radio stations in the United States. It is syndicated by
Talk Radio Network and now reaches 130 radio stations and
America's Talk on
XM and was the only nationally syndicated science radio program. When Kaku is busy filming for television, ''Science Fantastic'' goes on hiatus, sometimes for several months.
Kaku is also a frequent guest on many programs. As a guest on the program ''
Coast to Coast AM'' on November 30, 2007, he reaffirmed his belief that the existence of extraterrestrial life is a certainty.

On January 28, 2007, Kaku hosted the Discovery Channel series ''2057''. This three-hour program discussed how medicine, cities, and energy could change over the next 50 years.
In 2008, Kaku hosted the three-hour BBC-TV documentary ''
Visions of the Future'', on the future of computers, medicine, and quantum physics, and he appeared in several episodes of the History Channel's ''Universe'' and ''
Ancient Aliens'' series.
On December 1, 2009, he began hosting a 12-episode weekly television series for the Science Channel at 10 pm, called ''Sci Fi Science: Physics of the Impossible'', based on the book of the same name. Each 30-minute episode discusses the scientific basis behind imaginative schemes, such as time travel, parallel universes, warp drive, and similar. Each episode includes interviews with other scientists working on prototypes of these technologies, interviews with science fiction fans, and clips from relevant science fiction movies.
