The Gardner Project : Looking to the future from today



What is the Gardner Project? (source)

The Gardner Project is an effort to develop a device that processes imagery based on faster-than-light particles (tachyon particles). Unlike a camera which processes light, thus depicting the present, this device should theoretically detect the particles originating from a point in time farther ahead than the present. Since faster than light particles move backward in time the particle imagery that is developed should theoretically depict what we would call "future" time.



About 'tachyon particles' (source)

A tachyon (from Greek, meaning i.e. swift, fast) is any hypothetical particle that travels at superluminal speed. In simpler terms, they are particles which are faster than light. The first description of tachyons is attributed to German physicist Arnold Sommerfeld; however, it was George Sudarshan, Olexa-Myron Bilaniuk, Vijay Deshpande and Gerald Feinberg (who originally coined the term in the 1960s) that advanced a theoretical framework for their study. Tachyonic fields have appeared theoretically in a variety of contexts, such as the Bosonic string theory. In the language of special relativity, a tachyon is a particle with space-like four-momentum and imaginary proper time. A tachyon is constrained to the space-like portion of the energy-momentum graph. Therefore, it cannot slow down to subluminal speeds. Even if tachyons were conventional, localisable particles, they would still preserve the basic tenets of causality in special relativity and not allow transmission of information faster than light.
