Message:


Newton said for every action there is an equal and opposite reaction.  Einstein 
said that space-time is relative to the observer.  Hawking said the universe is 
shaped somewhat similar to a saddle.
If all the matter in the universe is removed, what will the shape of the 
universe be?  Apparently, Einsteins theories on relativity do not state that 
space-time and matter are co-dependent on one another.  But relativity is a 
result of the interaction of space-time and matter.
The universe then, is the shape it is because of the matter within it.  If the 
matter is removed, the universe should take another shape.  What is that shape?
