OK since we talk crazy stuff here I have one... what if taste of banana is fundamental characteristic of matter? Seriously. Color was not considered to be fundamental property of matter but Bohr was looking trough prism heated gases and figured out that spectrum is not full but just distinct colors... and then he concluded that electrons can be found only on certain quantum levels and jump in between emitting light. My crazy idea is based on various patterns we see, flower Fibonacci sequence how they firm shape, then shell, galaxy... but there are some other patterns we see corrections everywhere from the smallest to the biggest scale. Since flavor and fragrance is one of the things how we human feel vibrations of molecules because it is fact that smell and taste are very connected and both are our sensation how molecules socialite and then we feel sensation of smell. That is how they make synthetic smell by making molecules that have similar spectrum to natural thing so you 'smell and taste banana but it an be pumpkin with artificial aroma'. Back to the topic those vibrations and variations follow some patterns and what is source of those patterns? If we look in string theory they are just telling us about all those weird strings oscillating in 11 dimensional space where the rest of 8 dimensions are so small that we do not see them or so big that all our universe is just spread on that membrane. Taste of banana might be echo of those fundamental properties on which is built superstructure of universe.
