RJA 8a: Freewriting:
In our small universe with only 4 dimensions, the laws of physics and quantum mechanics cannot be unified. The major problems stopping unification are that of the weak force of gravity when compared with the other three forces of electromagnetism, strong, and weak nuclear forces; and the issue with light, which can move as waves or photons. The current theory on this is that we are only seeing a small part of the big picture. We need to expand our scope of vision so that we can see the entire picture.
The Kaluza-Klein Theory was published in 1921. It added a fifth dimension which unified the issues of light and gravity with the other laws and forces. This theory was that first accepted look at hyperspace and started quite the sensation. Kaluza-Klein Theory has evolved in to what we today call “String Theory” or “Superstring Theory. In these theories, sub-atomic particles, the building blocks of everything, are either fermions; which make up matter, or bosons; which make up force. These fermions or bosons are simply strings of energy, which can be a line or a closed circle, and vibrate at certain frequencies depending on what sub-atomic particle they are, or choose to be. The elegance of this theory is observed through Supersymmetry, which states that for every boson there is a corresponding fermion.
The current theory is that we live in a ten dimensional multiverse. This is the correct amount of dimensions needed to unify the study of the tiny sub-atomic particles of quantum mechanics, with the study of the immense and massive of cosmology. These dimensions are tiny and curled up, so that we do not currently have the technology or knowledge to locate them. However with them, all four forces become aligned; light acts as we would expect; and the universe simply makes sense.
