Missing pieces in the Standard Model

Standard Model explains all about basic forces and smallest atomic particles. There are four fundamental forces -- Gravity, Electromagnetic force, Weak force and Strong force.

Electromagnetic force is the magnetic force between electric charges.weak force is the force inside an atom between its particles like protons and neutrons. Strong force joins smaller subatomic particles to create protons, neutrons,etc.

Standard model explains all about these three forces. But it is not the same with Gravity. The origins and behaviour of gravity is still open to questions. There are more unsolved mysteries -- what is dark matter, why is there more matter than anti-matter, etc. It is upto future scientists like you to fill in these missing pieces.
