Hundreds of particles known, in the spirit of Mendeleev, they can be grouped according to a few fundamental constituents.

“Feynman diagram” The uncertainty principle allows “virtual particles” to exist for a very brief amount of time.

The “forces” are particles themselves!

Weak interactions Strong interactions Gravity??

Why do we need huge accelerators?

You need a huge amount of energy to make a virtual particle (such as a force carrier) real so that you can study its properties and interactions

Remember you need a wavelength on the order of the size of an object to image it Higher energy=higher frequency= shorter wavelength

We are recreating the conditions that existed in the early universe
