Sliders

Sliders is an American science fiction and fantasy television series created by Robert K. Weiss and Tracy Tormé. It was broadcast for five seasons between 1995 and 2000. The series follows a group of travelers as they use a wormhole to "slide" between different parallel universes. Tormé, Weiss, Leslie Belzberg, John Landis, David Peckinpah, Bill Dial and Alan Barnette served as executive producers at different times of the production. For its first two seasons it was produced in Vancouver, British Columbia, Canada. It was filmed primarily in Los Angeles, California, USA in the last three seasons.

Since its debut on March 22, 1995, the first three seasons were broadcast by the Fox network. After being canceled by Fox, the series moved to Sci Fi Channel for its final two seasons. The last new episode first aired on December 29, 1999 in the United Kingdom, and was broadcast on Sci Fi Channel on February 4, 2000.

Premise

Michio Kaku explains in the appendix of his book, The Future of the Mind, that the Sliders series "began when a young boy read a book. That book is actually my book Hyperspace, but I take no responsibility for the physics behind that series." The show follows a group of people, called "Sliders", as they travel ("sliding") between different Earths in parallel universes via a vortex-like wormhole, hoping to return safely to their original Earth Prime. The vortex can only be opened at random intervals on each new world, monitored by a countdown clock on a portable timer that they carry; failure to open the vortex in time would strand the Sliders for 29.7 years in that universe. While waiting for the timer countdown, the group learns about the differences in the alternate Earth from their own, and often become unwillingly involved in events that they must resolve before they can safely leave via the vortex. The travelers have no control over what world they end up in, but continually look for means to find Earth Prime.
