Telism

Telism was an artificial force carried by telons. When applied, telism allowed for the use of energy to push directly against the momenton field, as if it were a solid object. This force could be used for propulsion of spacecraft, as it was far more energy efficient and precise than using thrusters (such as rockets or ion engines).

Telism could also be used on the surfaces of planets, but traherism was much more efficient in these environments. Traherism, however, required the presence of a large amount of matter to push against, whereas telism did not.
