Our actions enable us to find out about the world. We sense energies of the universe and are able to comprehend these through full real life experience.
We know that all the elementary particle interactions are essentially exchanges of energy. In the 20th century many new particles including the neutrino and quark were discovered as fundamental energies functions.
To make sense of all the elementary particle experiments we need to identify energies of the universe that function though these interactions. In the 21st century cosmic astroparticles have been demonstrated to freely come together at all energies.
Full real life experience enables us to comprehend all these elementary particle interaction experiments. Different energies of the universe come together to make all the variety particles.
