Sigtrygg said:Note that the bubble T5 refers to is a bubble of our normal spacetime and quantum fields - this bubble of normal space is maintained by the hull.
It is not hydrogen filled, it is a vacuum of four dimensional spacetime and the fundamental quantum fields of our universe maintained as a bubble of the quantum foam that makes up the jump dimensions.
In T5 the hull grid wiring maintains the normal universe field conformal to the hull and a metre or so extended beyond it. It is a field, not a bubble of hydrogen.
The jump bubble version extends the normal space bubble as a sphere around the ship, but again it is a field that maintains our normal space within, and once again it is not filled with hydrogen.
Not filled with, used to create.
