# In physical Science, particles are consider to be small localized objects which can be ascribed several physical or chemical properties such as in volume or mass..  # In a large number of particles realm we have “Statistical System” to count the particles.  # Particles are in various forms and are present everywhere such as in solid, liquid and gases. When we talk about their sizes according with others then we have quantum mechanics microscopic particles macroscopic particles and even more smaller level particles.  # There are composition of a particles known as “Composite Particles” that are made with other particles. We have elementary particles such as quarks, leptons, mesons, muons gluons and many others..  # Particles build up almost everything into the entire universe and hence in space also.  # But why existence needs particles and why there is any need of particles as these are infinite or something still beyond these particles hovering a darkness on some aspects of na
