Our universe is vastly diverse. Everywhere where we see, we see different things. Practically no two things are the same. Different forms, different sizes, different matters, different properties everywhere. Where is this diversity come from? Are these differences rooted in the foundation of our material world? If everything around as is so diverse, how diverse are the building blocks of our world? Can our universe simple, if everything in it so diverse?
Yes, it can, and it is. Our universe's building blocks are the elementary particles. We know a kind a few of them. The most commons are electrons, protons, and neutrons. We know hundreds more, but almost all are not really elementary but complex particles, or there are on different excitation levels, so they only look different. According to the standard model of particle physics, only a few of the really elementary particles exist, and even most of them are not seen in everyday life. Our ordinary matter built only by up and down quarks, and electrons, we have lots of hardly seen neutrinos, and a few types, different particles to transfer forces, like photons. Our universe almost entirely built from just a few of these different particles. And every of the same kind of these particles is completely the same. More then just the same, they are absolutely the same, no way we can distinguish for example between two electrons. They are theoretically the same. And it goes for all of the different kinds of particles.
Where the diversity of the universe is come from then? The physical laws allow the combinations of these particles, and these combinations are so vast that practically no two same particles above the molecular level in the universe. Every sand grain, every snowflake is different, as practically everything is different and unique above the molecular level. However, on the molecular level and below that, same particles are really the same, theoretically are the same. And everything built from just a few different building blocks. Our universe is simple. But how simple? Where this sameness and simplicity drive toward us?
Did we already reach the bottom of the foundations? Are the building blocks of the standard model the most basic particles? Are the electrons, neutrinos and the quarks the most fundamental particles? We think they don't have inner structures. However, certainly, they are not the bottom of the building structures. Our universe must be simpler than that.
They are theories that are below of the standard model. String theory is a kind of candidate, but there are more like loop quantum gravity or the grid model, and there several more. All of them are convinced that our universe must be simpler than the standard model. It must be.
Sooner or later we surely recognize that our universe actually built only on one kind of particles which are absolutely the same. These same particles with the different level of excitations and energy, produce all the diversity of our universe. Our universe must be this simple. Let's find this out!
