Turning a broad field into a controlled passage
The throat is the proposed physical interface between a very large capture envelope and the machinery housed in the spacecraft.
Known effects vs. proposed extrapolation
Converging nozzles, flow conditioning and differential pressure are well understood for ordinary fluids and plasmas under stated conditions. They cannot simply be applied to unknown dark matter.
What the working reports suggest
The notes quote an approximately 1.2 km intake throat; alignment vanes, vortex stabilizers and field gradients are proposed to guide the substrate into the magnetic section. Their effects depend entirely on a validated coupling model.
How material or energy would move
- Receive particles from a much larger projected collection cross-section.
- Condition momentum and angular distribution to avoid mechanical loading.
- Deliver a measurable flux, with mass and energy accounted for, to the solenoid.
The engineering uncertainty
A funnel-shaped drawing does not establish that a hypothetical dark medium responds to a physical wall or magnetic field. The source of convergence work and momentum has not been computed.
What a rigorous test needs
Measure incoming and outgoing momentum distributions, losses and backreaction through a testable interaction model; compare with a no-field control.
