For quite some time, Ronald Mallett has been working on plans for a time
machine. This machine uses a ring laser and the theory of relativity.
Mallett first argued that the ring laser would produce a limited amount
of frame-dragging which might be measured experimentally, saying: In
Einstein's general theory of relativity, both matter and energy can
create a gravitational field. This means that the energy of a light beam
can produce a gravitational field.
My current research considers both
the weak and strong gravitational fields produced by a single
continuously circulating unidirectional beam of light. In the weak
gravitational field of a unidirectional ring laser, it is predicted that
a spinning neutral particle, when placed in the ring, is dragged around
by the resulting gravitational field.
In a later paper, he
argued that at sufficient energies, the circulating laser might produce
not just frame-dragging but also closed timelike curves, allowing time
travel into the past: 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.
Funding for his program, now known as The
Space-time Twisting by Light (STL) project, is progressing. Full details
on the project, Mallett's theories, a list of upcoming public lectures
and links to popular articles on his work can be found at the
professor's UConn web page, and an illustration showing the concept on
which Mallett has designed the time machine can be seen on a Geocities
webpage.
He also wrote a book titled Time Traveler: A Scientist's
Personal Mission to Make Time Travel a Reality, co-written with New
York Times best-selling author Bruce B. Henderson, that was first
published in 2006. In June 2008, motion picture director Spike Lee's
production company announced it had acquired the film rights to
Mallett's book. Lee is co-writing the movie script and directing the
picture.
