Examples
-
The inter-particle distance in collisionless plasma is so large that objects of collisionless plasma can easily pass through each other.
-
It is the end behaviour of the plasma that you have a problem with and is likely the core of most PC/EU invalid assumptions – as most of it becomes just uninteresting and boring collisionless plasma that interacts with nothing but itself!

Most of this collisionless kind is just sitting in space, and is not connected to any organised electric or magnetic field.

There is no true observational evidence of the quantity of collisionless plasma nor can it be formally observed – only because it doesn't show itself. it is about equally ubiquitous as dark matter or dark energy – and we are yet to find that too!

Review the following: Structure of the dissipation region during collisionless magnetic reconnection: The simulations reveal that the dissipation region develops a two-scale structure: an inner electron region and an outer ion region.

-
Close to the X line is a region with a scale of the electron collisionless skin depth, where the electron flows completely dominate those of the ions and the frozen-in magnetic flux constraint is broken.

-
Dark matter is predicted to be collisionless and will be scattered very easily by baryonic gas clouds and stars.
What’s the (Dark) Matter? John 2008
-
Tell me right up front exactly how your theory explains how a force can point somewhere other than in the direction of its source, and why your theory miraculously reproduces all of the predictions of the dark matter idea (which is, at heart, extraordinarily simple: there is some collisionless non-relativistic particle with a certain density).
Dark Matter: Still Existing Sean 2007
-
As the two clusters passed through each other, the hot gas in each smacked into the gas in the other, while the individual galaxies and the dark matter (presumed to be collisionless) passed right through.
Dark Matter Exists Sean 2006
-
They are the first rigorous results to establish fast decay to equilibrium in confined collisionless time-reversible dynamics.
