It’s a big deal when trying to unify relativity with quantum physics. A force-carrying particle would add a quantum value for gravity to the current quantum zoo of particles and give us a totally new way to model gravity, from the least possible unit to all of the universe. If it turns out gravity is a force we’d be able to seriously consider modeling the interiors of black holes. We could more precisely model orbits. We could directly hypothesize anti-gravity technology. We could build weapons that make nukes look like cat farts. Getting ahead of myself…
