It will take earth-based accelerator experiments to identify its fabric. The strong force is responsible for quarks sticking together to form protons, neutrons and related particles. The weak force facilitates the decay of heavy particles into smaller sibblings. The gravitational force acts between massive objects. Although it plays no role at the microscopic level, it is the dominant force in our everyday life and throughout the universe.
Particles transmit forces among each other by exchanging force-carrying particles called bosons.
These force mediators carry discrete amounts of energy, called quanta, from one particle to another. You could think of the energy transfer due to boson exchange as something like the passing of a basketball between two players. Physicists expect that the gravitational force may also be associated with a boson particle. Named the graviton, this hypothetical boson is extremely hard to observe since, at the subatomic level, the gravitational force is many orders of magnitude weaker than the other three elementary forces . Although it is a staple of science fiction, antimatter is as real as matter.
