eli5: How does gravity bend space-time when space is…nothingness? How do you bend nothing?

Question

I understand time has more of a construct to it making it easy to manipulate and bend but I don’t understand how the same can be true for space. Doesn’t the fact that space bends means it something fundamentally rather than nothing emptiness?

Answer 1

Objects and particles near or at your location are bent as they move toward or away from you by gravity. This bending can only be measured from your location, and this is true from the object’s point of view too.
