“Feynman diagram”

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

Weak interactions

Strong interactions

Gravity??

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

QuickTime™ and aTIFF (Uncompressed) decompressor

are needed to see this picture.

We are recreating the conditions that existed in the early universe
