   What a poor understanding of reality.

   It's more common sense then to deny any form of reality. All observers   
   see appearances.

   No indeed, "obviously" there are only appearances.

   Would it? You forget that with Earth, the whole universe is rotating   
   around B1, so that ultimately it is only B1 who is feeling the "real"   
   rotational force acting upon them, from Earth + Universe.   
      
   When you look askew at an object, you will see it kind-of contracted, so   
   is that real or not? Do you only see the object "really" when looking at   
   it from a perpendicular view? In all other cases, will you infer stress   
   forces in the "contracted" objects?   
      
   Now try this kind of "observations" when time and movement come into   
   play, remembering for once relativity of simultaneity.
