(written from a Production point of view)

The Physics of Star Trek is a popular-scientific work written by scientist Lawrence M. Krauss. Written in a style, easily accessible to a general readership, Krauss explores several scientific topics and phenomena in the field of physics, often referenced to in imaginary science fiction properties, such as Star Trek, and how they relate to real-world science. As the title already suggests, Krauss uses examples from the live-action Star Trek productions as illustrative backdrops, though examples from other properties such as Star Wars and the movie Independence Day (1996) also passes the revue.

The book contains a black-and-white photo section that showcases real-world scientific equipment and spacial phenomena.


"Today's science fiction is often tomorrow's science fact. The physics that underlies Star Trek is surely worth investigating. To confine our attention to terrestrial matters would be to limit the Human spirit."
– from the foreword by Stephen Hawking

  • Foreword by Stephen Hawking
  • Preface

Section One

A Cosmic Poker Game
In which the physics of inertial dampers and tractor beams paves the way for time travel, warp speed, deflector shields, wormholes, and other space-time oddities.

Section Two

Matter, Matter Everywhere
In which the reader explores transporter beams, warp drives, dilithium crystals, matter-antimatter engines, and the holodeck.
