 Others think the framework depends on what it frames. Like Leibniz, Albert Einstein pictured (or “pictured”) space as an abstraction from relations between objects. Consequently, space can be described with the same metaphors we use for family trees. Maybe space grows bigger. Maybe space is curved or warped or has holes. There is much room to wonder why space has the properties that it has. But since space is an abstraction from objects, answers to any riddles about space reduce to questions about objects. One can wonder why there is space. But this is only to wonder why there are objects.
