Time Particles are a type of particle apparently involved in the fabric of spacetime; it is likely they are involved in time travel, and it is known for sure that they can be manipulated to produce dimensional travel.
In 2003, Gyro Gearloose managed to isolate a limited number of Time Particles, which he used as fuel for a dimensional vehicle, the Alternate Life Machine. He soon discovered, however, that the Time Particles were unstable and degraded quickly when so harvested; as a result, Gyro was only able to use the A.L.M. once before he was forced to shut down the project.
Behind the scenes Edit
Time Particles were first mentioned in 2003 in Donald Duck and the Alternate Lives.
