Things become trickier if there’s an intermediate target between the force and the object. At some point conservation of momentum gets called in question. ---

One interpretation of that visual is that the Unstoppable Force just misses the Immovable Object. It clearly passes behind it! What we see is a graphic of someone, at the last second, thinking “It’d be better if I turn this a bit so they miss each other.” (very wisely, I might add…) ---

I feel like this would cause light passing through the outer portions of galaxies to be blurred. Basically a form of gravitational lensing, but due to the small scale it would be more of a repeated scattering effect. Photons that got near one would have their path diverted very slightly, and repeated perturbations would be a spreading function. It seems the particle would have to actually be a small black hole, though I guess it depends on the theoretical justification. It would have to be immune to Hawking radiation, since otherwise it would evaporate immediately. I suppose it wouldn’t be different from other particles in that respect. One also wonders how these particles formed in the first place. If they only interact via gravity, then there’s no means for them to form in the universe. Were they just always there? ---

I thought it was alien life forms that decided to convert all stars into white dwarfs for maximum lifetime, dooming baryonic lifeforms to extinction until they built a giant portal to another universe and fled there. ---
