Chen Chen was always under the impression that the Galaxy pendant had other outlets for releasing its energy apart from using such primitive methods of collisional release.
Unfortunately, Chen Chen could not find any alternative methods for releasing its energy apart from resorting to such primitive methods. He had tried immersing it in a chemical solution, attempted to simulate it using extreme heat and cold, and many other experiments but to no avail.
It made sense he would have trouble with it considering it was alien technology. In the movies, they were an advanced civilization that had long developed interstellar travel technology where they were capable of obliterating the Earth with just one shot. Therefore, it was no surprise that Chen Chen was unable to solve the mystery behind the Galaxy pendant using the technology currently available to him.
