Tachyons

A Tachyon is a type of special, faster than light, subatomic particle.

Overview
Tachyons are very similar to Dechyons as they both travel faster than light and have no mass. They also both interfere with the space time fabric. Tachyons occur naturally in space as they can be created when energy turns to mass. Tachyons are stable and do not decay. They are known to cause damage, rips, bumps and tears in space time. This leads to temporal anomalies in space time. Portals through time and worm holes with different temporal coordinates are generated by these. They often accumulate in areas where temporal distortions are common.

Effects
Tachyons are known as the time particle. This is because the interfere with space time causing all kind of anomalies from wormholes to time portals. They are similar to Dechyons except they only create distortions to other locations in time rather than different location of space. Tachyons are able to send messages back in time but it is very hard to make this happen. They normally open small temporal anomalies and enter them before being ceased from existence. The anomaly then shuts as it does not have sufficient power to remain open. If a large quantity of them accumulated somewhere temporal distortions will occur possible opening temporal rifts to other places in time. Despite this it is very hard to artificially do this and has never been done. They also often are created when something else creates a temporal anomaly.
