Dark Energy is a force said to be responsible for cosmic expansion, and one of the theorised carriers of this force is the Chameleon Particle. To describe its effects, due to its non-linear self-interaction, it has a variable level of interaction. In places where the density of matter is relatively high, chameleon particles are heavier, interacts very weakly with other matter and only over very short distances (in the range of less than 1mm).
However, in inter-galactic space where matter density is extremely low, the particles are lighter, interact much more strongly with other matter and over very large distances (over 100,000+ parsecs). This means that the particles could be exerting a force that is pushing the universe apart in outer space.
Here is a more detailed explanation: https://skyandtelescope.org/astronomy-news/is-dark-energy-a-chameleon-0824201523/
Assume a world where this theory is correct, and this elusive particle exists. Additionally, assume that they can be mass produced. Could this be used in outer space (where density of surroundings is very low) as a weapon to concentrate the effects of pre-existing dark energy, "pushing" planets and stars from a distance? If not, is there any other way to use them in space for military uses?
Note: This is completely different from my original question. That one referred to space constructs. This is another application. Also, as a side note, I already fixed the old question, so can someone do me a favour to help reopen it?
