Subject: Does metaphysics explain the universe better/ more acrurate than science?

1. Is metaphysics (Aristotle, Aquinas) science?
2.No empirical science can prove or demonstrate that materialism is true.  
2.Materialism is a philosophical assumption. 
3. Does metaphysics say more about the universe than physics.

Are these statements true?
I am asking because of a disagreement I am having with someone and this came 
up.  

Are these statements true or false?
