Essentially, it would be a box with a door that would open in the direction of the rocket's movement to scoop up dark matter. When dark matter goes into the box, the door closes, and the box shrinks to compress the dark matter and increase …

Web"Dark matter" refers matter of an unknown type that astronomers and cosmologists believe must make up the majority of the mass in the universe. It is called "dark" because it does not emit any light. We know of its presence because of the gravitational effects it has on objects that we can see. WebIn standard cosmology, the whole thing that makes it "dark" is that it only interacts weakly with normal matter (perhaps only gravitationally). That makes it very hard to probe. And there in the standard model, there aren't any good candidates for particles that fit the dark matter constraints. Personally, I don't think dark matter exists.
