. Hawking the philosopher .

Howdy Gerald L. O'Barr ,  You make an interesting ,
  yet invalid observation :
" Science is totally different than philosophy ,
    since science has a way to determine 
      if something is to be accepted or not ,
      and philosophy has no way to tell what is right or not "

The boundary between physics and metaphysics
  is always being pushed back .

Philosophers know  Tons  of physics ...  and vice versa .

Why else do you think Stephen Hawking 
  is such a best selling author ?
