Travel Through Time… by Using a Laser?

A physicist believes that time travel is possible, and his theory involves circulating lasers. Are we close to real time travel?

Recent Research

As a fan of H.G. Welles’ novel The Time Machine, Ron Mallett has built on Albert Einstein’s equations for the exterior and interior gravitation fields of the light cylinder.  Einstein’s theory of general relativity support travel to the future (in theory).  When Mallett read The Time Machine he saw the possibility of traveling backwards in time.  

Well, In theory.

Mallett was motivated by his desire to go back in time and save his father who died at 33 years old. Devastated by this tragedy, 10-year-old Mallett discovered Welles’ book.  He was inspired and wanted to build his own time machine.

Unable to afford university, Mallett enlisted in the US Air Force and, after serving his tour was entitled to a degree on the GI Bill.  He studied hard and received a PhD in physics from Pennsylvania State University.  His breakthrough theory builds on Einstein’s gravitational field equations and posed that if gravity can affect time and light can create gravity, then light can affect time. This theory has come to be known as Space-time Twisting by Light (or STL).

Space-time Twisting by Light

The circulating laser approach is based upon a ring laser’s properties in the context of Einstein’s general theory of relativity. Professor Mallet proposed that a circulating laser might be able to produce a limited amount of frame-dragging which might be measured experimentally.

Mallet later argued that the circulating laser might, at sufficient energy levels, produce not just frame-dragging but also closed timelike curves (CTC), allowing time travel into the past.

From one of Professor Mallet’s published papers:

For the strong gravitational field of a circulating cylinder of light, I have found new exact solutions of the Einstein field equations for the exterior and interior gravitational fields of the light cylinder. The exterior gravitational field is shown to contain closed timelike lines.
The presence of closed timelike lines indicates the possibility of time travel into the past. This creates the foundation for a time machine based on a circulating cylinder of light.

Mallett, R. L. (2003). “The gravitational field of a circulating light beam” (PDF). Foundations of Physics.

Here is a NBC News / NBC Left Field segment that interviewed Professor Mallet and provides a great introduction to his research and theory….

His resulting invention only sends information back through time, not people.  He has built a prototype showing how lasers could create a circulating beam of light that twists time and space. But he still needs substantial funding to bring his idea through to a working model.

The book describing his journey was published in 2006, titled Time Traveler: A Scientist’s Personal Mission to Make Time Travel a Reality, co-written with author Bruce Henderson. The film rights for the book have already been optioned for a motion picture.

Time, indeed, will tell if lasers will take us back to the future.

How Laser Safety Certification can help

At Laser Safety Certification, we have laser safety courses and Laser Safety Officer (LSO) certification programs to make sure your team are correctly using lasers and your customers are protected. We provide certification programs that follow the OSHA recommendations and ANSI guidelines for laser safety.

For more information about industrial laser safety, check out our courses for Industrial Laser Safety and Industrial LSO certification. For more information about medical, health care, or veterinary laser safety, check out our courses for Healthcare Laser Safety and Healthcare LSO certification today. For cosmetic laser safety, see our Cosmetic Laser Safety and Cosmetic LSO Certification courses for more information. We also have an FAQ section with common answers about our courses, certification options and kit offerings for your LSO to manage your own safety program.
