The scientists are hoping to see a unification of the four fundamental forces of nature that act on these particles (the weak force responsible for radioactivity, electromagnetic force, the strong force responsible for the existence of protons and neutrons, and gravitation).
we don't really know how to unify the forces of nature -- the weak force, the strong force, the electromagnetic force, all of this we are not able to comprehend what it all means in terms of the physical laws of nature.
But not to literary dissolution, for a poetics makes a truth--claim: "a poetics does not record the strong force of hard facts; it describes the weak force of a call for the kingdom, or for justice, which is true even if the real world is truly unjust.
Stymied by the threat of libel suits and various restrictions, opposition parties remain a weak force in the city-state.
But detecting such a weak force is a challenge, one that until fairly recently was deemed outside the ability of science.
Because these particles are very massive their range is too short to allow their direct exchange between nucleons interacting via the weak force.
Gravity comparatively is a very weak force, however, and even Einstein questioned whether these waves could be detected.
