  From the humble beginnings of particle physics to groundbreaking discoveries,
the journey of particle physics has revolutionized our understanding of the
universe. The progression of particle physics, begin from the discovery of new
particles, to gauge symmetries and many successful theories in its journey
which help in building up the model that explain the underlying makeup of
matter, regulated by fundamental forces led to establishment of Standard
Model(SM). The discovery of neutrino oscillations compelled scientists to
explore theories that extend beyond the Standard Model, which opened up new
frontiers in the field of particle physics. The theories have shifted its
paradigm to a single comprehensive theory at the scale of 10^14 GeV. This
article explains the journey of particle physics from the basic constituent to
the theory of everything.
