The Science of Star Wars

Could spaceships really travel faster than light? And what would happen in a real-life lightsaber fight? To mark the release of Star Wars: The Force Awakens, Surrey experts in physics, space systems and engineering explore the facts behind some of the greatest fantasies in science fiction.

Star Wars: fact vs science fiction

In our Science of Star Wars videos, University of Surrey academics and Star Wars fans Professors Jim Al-Khalili, Yang Gao, Ben Murdin and Julie Yeomans discuss the science behind Star Wars and how far what you see on screen is from reality.

Episode I: Phy-ction

Jim Al-Khalili, Professor of Physics and Professor of Public Engagement in Science, explains the physics of hyperspace and how it may be possible for spaceships to travel faster than the speed of light.

Einstein’s special theory of relativity tells us quite categorically that nothing can travel through normal space faster than the speed of light. The only option, therefore, is to find a shortcut that takes you out of normal space – a wormhole.

Episode II: Droids

Yang Gao, Professor of Space Autonomous Systems, discusses the current role of robotics and the fascinating future of robots in space.

Looking into the future, different kinds of robots will work side-by-side with humans to materialise our goals and ambitions to explore the new frontiers of space.

Episode III: Lasers and lightsabers

Ben Murdin, Professor of Physics, unravels the physics of lightsabers and what would happen in a real-life lightsaber fight.

If a real lightsaber’s laser light was red or blue, like in the films, the light would keep going for miles and maybe punch a hole in the roof, the floor or even slice off your own toes.

Episode IV: Body armour 

Julie Yeomans, Professor of Ceramic Materials and Head of the Department of Mechanical Engineering Sciences, tackles the subject of body armour and protective suits, and explains how Surrey research is contributing to the development of materials that could save lives.

In the real world, armour has to deal with a growing variety and increasing severity of threats. Surprising though it may seem, for the best possible protection in terms of ballistic resistance for a given weight, ceramics are the materials of choice.
