collisionless
Never touching anything
Collisionless describes a system or process in which particles or objects don't physically collide with each other.
The term appears mainly in physics and astrophysics, where it characterizes plasmas or stellar systems in which particles interact through gravitational or electromagnetic forces rather than direct contact: collisionless plasma, collisionless dark matter.
A collisionless shock wave propagates through electromagnetic interactions rather than particle impacts.
