Of course, enabling a massive spacecraft to make short-range leaps is not a simple task.
Warp subspace and curvature subspace have essential differences.
To enter curvature subspace, a flying unit must first use a Medium Engine and similar curvature space compression technology to keep accelerating until it breaks the speed of light.
At the moment of breaking the speed of light, a perfect curvature bubble will instantly form, and a sudden mutation will occur at the border between it and the original three-dimensional world.
The vehicle and curvature bubble will directly enter the curvature subspace.
As long as the speed can be maintained above the speed of light, it will not be thrown out.
Warp subspace is different, as the material is first wrapped by the warp subspace layer, but the relative speed between the material and the original three-dimensional space can be 0.
