Neil deGrass Tyson said something very important and profound on his podcast show ' Star Talk Radio ' in the 'Cosmic Queries: Gravity' episode. I am writing it down here because I want to keep this handy. "There is no reason to think that gravity does not also have a quantum manifestation of itself because everything else has a quantum manifestation. We know based on how matter manifests in small sizes that it could reveal itself as a wave or as a particle depending on how you measure it and under the circumstances at which you conduct the experiment." "It is a very human thing to say, is it this or is it that? Is it a planet, is it not a planet? Is it less filling or great taste? Is it gum or is it candy? These are false psychotomies. Somethings can be both. But, our language requires that it fit into one word or another. What we are not recognizing is that it is not a fault of the object or the concept. It is a defect in our language." ...
It has to be simple.
