   As far as the question of  "is space is physical thing".

     Yes, you can ask any particle Physist that.  For example, did
 you know that vacuum is NOT empty!  The most perfect vacuum God could
 ever make would have "virtual particles" zipping in and out of existance.
     Vacuum can exert a pressure on you!  It is known is the Casimir effect
 (or something like that.)  In a vacuum two parallel metal plates would
 attract each other due to the pressure of vacuum (over and above the
 gravitational and electrical attractions they have.)
