I 100% believe that the Quantum World does exist, and all mass is created from the identical processes replicated through nature and the universe. As they predict "If you can understand Quantum, then you understand the Universe". If you zoom out and look at the structure of a Galaxy and the mechanics of how stars are made, then zoom in to see how stars create planets, the process is the same, and by studying the formation of the precise mechanics of these two systems then similarities and common factors start to appear. But the missing piece related to what some theorists call string theory is at play from a minuscule size to the gigantic. (These theory's are not far off the mark and not as complicated as they think!)
Science has overlooked this very simple mechanism right from the beginning, and not relating it to the mechanics of the systems at play, but can be seen visibly in many forms all over the universe and right here on Earth. This is soon be revealed, and the missing link will change science as we know it forever!
