Under the conditions of the last subsection, the possibility of a
Repulsion spacecraft appears to be feasible at least in theory,
provided that some relationship between its shape and the
probabilities discussed can be found or assumed.

One simple assumption is that the spacecraft itself is shaped like a
truncated (cut-off somewhere) heavy-tailed/fat-tailed distribution or
random variable. Instead of having a long needle-like "nose", it
would simply slowly taper off as one goes toward the front off the
spacecraft. How slowly it tapers off and how long the spacecraft is
to be are open questions, although the probability/statistics of
"censored" and "truncated" statistics can help considerably at least
partly, and there is a literature on these although none to my
knowledge are related to spacecraft.

A more complicated assumption is that the spacecraft also or
alternatively should literally have Memory - like viscoelastic
materials or even biological materials or the science fiction notion
of an "android" - a biological-metal robot.

An even more complicated assumption is that the spacecraft is partly
composed of a wave or field component. According to the previous
posts, the Strong and Weak Interactions are Repulsive, so we will need
to harness these fields, first on the quantum level, then try to
extend them to the semiclassical or macroscopic levels. The
repulsion between one electron and another, or between one proton and
another, may actually involve clues if not the direct macroscopic
generalization of strong and weak interactions - part of
electromagnetism may be the generalization of strong and weak
interactions to the macroscopic domain. A wave or field needs to be
set up "shooting forward" in the direction of travel of the
spacecraft, somewhat like a generalized soliton that slowly tapers.
