Friendly reminder that "Science," natural philosophy, is limited in scope. It can only give you answers about the material world, the dynamics, ratios, and relationships between objects in the material world.

Questions like:
"What is fun?"
"Scientifically speaking, what is love?"
"Prove God exists scientifically"

Are category errors. Science cannot answer these questions. It is methodologically incapable of answering these questions. Philosophy is what you are seeking. Read books on various philosophical disciplines. Natural philosophy is merely one branch of the tree, and you are shaking the wrong limb hoping fruit will fall in your lap.

That is all.
