BASED ON OUR CURRENT KNOWLEDGE, THE UNIVERSE IS COMPOSED OF ENERGY FIELDS SUCH AS THE ELECTROMAGNETIC FIELD, THE GRAVITATIONAL FIELD AND THE BROUT-ENGLERT-HIGGS FIELD.
They interact through the exchanges of energy that we detect in the form of particles. Imagine these particles as little poppies standing out against a field of wheat as the wind blows. These particles give us information about the fundamental laws of nature but we cannot see the whole picture with our present scientific instruments. A next generation of more powerful colliders like those proposed by FCC could offer higher precision in examining this picture and could shed light on the hidden sectors of the Universe.
