How can Space, the volume of the Universe, be bent?


Recommended Posts

From t0 Space expands 3D by Time? Must be a spherical shaped entity.

Than the system must be finite at least from the point of spacetime (from t0 to t-now) , energy and matter. Or?

But does space itself can be bent? How? 

Does spacetime has any physical properties can be curved?

Isn’t energy bends under the influence of gravity? Having a slightly curved extend, which is the local space of a physical entity in the moment of observation within the volume of the Universe. 
 

I agree that curved physical entities (waves…everything) can exist within any point of space. 
 

How the elements of a 0 set can be bent?

From your somewhat  muddled post, the above needs correcting.Mass/energy curves/bends/warps spacetime. We feel that geometry as gravity.

As John Wheeler said, mass/energy tells spacetime how to curve; spacetime tells matter/energy how to move. [or words to that effect]

We don't know...that's simply how GR models it. A number of us have been arguing with the reality/truth or otherwise of spacetime warpage and gravity. If space, spacetime has a property, it is I suggest expansion and whatever is making that expansion accelerate. But there are others that may like to elaborate.

Relationships between events - measurements of space and time differ in the presence of mass-energy, as compared to some far-away reference.

The mathematical object that describes these relationships is called the metric.
