   I'm not inside a balloon.  Maybe you are.

   "Just", indeed.  It will be somewhat more complicated than that.

   Doubtful.  Three year olds don't have developed concepts of space and   
   time.

   No, he said the reverse, but not with any earnestness.

   This is unknown.

   The word is spelt "boundary", by the way.   
      
   I ask again, what's this supposed boundary made of?  What would happen to   
   an object hitting it?  What is outside of this supposed boundary?   
      
   >  It is limited in space...and Time.   
      
   So's the surface of the Earth, yet that surface has no boundary.

   Meaningless, unless you can say exactly what you mean by a mathematical   
   concept "not existing".   
      
   > What's wrong with hitting a wall anyway????   
      
   Get into your car and try it.  You'd soon find out.

   What wall?  Just because space is expanding, doesn't mean there's a wall.

   Sadly no.
