Physics is about researching existence.
Metaphysics is about experiencing existence.
Physics pulls evidence of aspects of the physical structure of existence apart, bit by bit. It then asks ‘what is it?’
It will never be able to provide the answer in our lifetime, if ever.
Metaphysics explains that historical experiences of reality reveal a reality beyond physical understanding or decription that already envelops humanity.
The inference is merely artificial human subjects like physics and metaphysics will be rolled over by evolution as the human race becomes its fullest, real spiritual self.
Science will disappear into human technology, physical mind stuff.
Metaphysics will be taken for granted, like breathing, become beyond the need for explanation.
All is Well.
