Main Question or Discussion Point
Can two objects that have no empty space between them move in opposite directoins?
Is there empty space between a marble and the glass table it moves acrossDoc Al said:They could be. But they can still rotate. Imagine two blocks stuck together. The system rotates about its center. So, one block goes left while the other goes right. (Momentarily.)
What are you getting at with this question? (I don't see any obvious physics here.)
I would say no, at least macroscopically.Avgiu said:Is there empty space between a marble and the glass table it moves across
