Tachyon: A tachyon is a subatomic particle that naturally exists at faster-than-light velocities, and can often be associated with time travel or produced as a byproduct of a temporal distortion.

Starfleet Academy. Courses. Temporal Mechanics. Temporal distortions. Dekyon: A dekyon is a subatomic particle which can be both naturally-occurring and artificially generated. Records: In 2368, distortions in the natural dekyon field were left over as "echoes" from previous iterations of a temporal causality loop in which the USS Enterprise-D had become trapped. The crew was able to use a dekyon emission to send a message into the next iteration, which set up resonances in Data's positronic sub
