How does physics explain the pyramids? Or writing?
Are the pyramids real? Is writing real? Are the meaning of words real?
A person wanted to build a tomb. It started as a thought. Are thoughts real? Are they part of the "real" world?
Physics only describes and explains what can be physically tested.
Maybe, we need to start teaching metaphysics like they used to do in the old days. Philosophy is okay, but we need to place more emphasis on it and expand. What discoveries await? World changing? Dimension changing? Can it be patented?
