Jiggle Me This

So there are 4 forces that explain everything? Gravity, strong and weak nuclear interactions and electromagnetism. So, what is that energy between our fingers when we hold them about an inch apart? And what is the phenomenon known as the Aura? And why is it that when we magnify an atomic particle to the highest capable magnification everyone sees something different? Things are made of littler things that jiggle, ok I get it, now if we could only figure out what those littler things are, and what it is that makes them jiggle, and why they jiggle in the first place!
To make a discovery is not the same as understanding a discovery but nothing will be able to be understood until that discovery is made. We need to keep searching, keep questioning, keep reaching for discoveries. Even if we don’t understand what purpose the discovery has, just making the discovery could have tremendous benefits. Maybe someone else will handle the understanding. Like Lisa Randall pointed out, who knew Einstein’s theory of general relativity would be utilized for GPS technology? Making the discovery has to precede the understanding, right?
