Danger said:One thing that seems a bit confusing at times is that gravity, while being the weakest of all known forces, is what binds the universe together. That's because it's also the only force that doesn't have an opposing force.

The weak interaction acts between both quarks and leptons, whereas the strong force does not act between leptons. "Leptons have no color, so they do not participate in the strong interactions; neutrinos have no charge, so they experience no electromagnetic forces; but all of them join in the weak interactions."(Griffiths)
Gravity is a fundamental force that exists between all objects with mass. It is responsible for the attraction between objects and is the reason why objects fall towards the Earth.
Gravity works by the curvature of space and time caused by massive objects. This curvature creates a force that pulls objects towards each other.
The weak force is one of the four fundamental forces of nature. It is responsible for certain types of radioactive decay and plays a role in the fusion reactions that power the sun.
The weak force is much weaker than gravity and only acts over very short distances. It is also responsible for the behavior of subatomic particles, while gravity is a force that acts on all objects with mass.
The weak force is essential for many technological applications, including nuclear power and medical imaging techniques like PET scans. It also plays a role in the formation of elements in the universe and the behavior of particles in particle accelerators.
