The resemblence to a fetus is not coincidental. That C shape is a mathematical probability under many circumstances involving chaotic (in the mathematical sense) formulae. There were a number of models created for biological and physical studies, and many of them spontaneously generate the C curve. You can see it also when you perturb fluids.
Well, I don’t know where all these math formulas are coming from, but all I can see is this pretty little heart shape and a lot of gas, and really, isn’t that the universe’s real message to us all, to get heartburn and belch?
