I'm just being facetious, and I'm sure this is a misunderstanding, but based on my reading of 40K fiction:
1. the Gellar Field protects a starship as it travels through the void/immaterium. It's pretty powerful. If it's breached everything goes to hell.
2. every person, except for nulls, has a connection, however tenuous, to the void/immaterium. During their lives, they shape it with their emotions. When they die, they return to it. Psychers can do much more with its energies.
So, given 1 and 2, as soon as you turn on a Gellar Field on a starship, everyone should drop dead (cut off from their soul energy / sliver chord /whatever) and no one should be able to use psycher-like powers. But this isn't what happens.
Just curious where I'm off.
As I see it, a Gellar Field is kind of like an artificial version of the barrier that separates realspace from Warpspace, holding the corrosive un-substance of the Warp at bay by a tiny pocket of reality. As noted, the real barrier between realities is somewhat permeable (to a variable degree based on physical and metaphysical location - there are some places where the wall between worlds is very thin indeed, and some where the veil has been torn), so it shouldn't be too much of a problem to assume that Gellar Fields (being an artificial equivalent) are permeable as well. Being that it's small, artificial and limited by artificial methods of power generation, a Gellar Field is arguably more fragile than the real barrier, so care must be taken by psykers aboard to avoid unnecessary use of their powers (they draw too much, they could breach the field and kill everyone on board… or worse).
