Open Question: What is space (or spacetime)?

3:30 Publicado por Flechado16

And can it expand? If it can expand can it expand greater than the speed of light?

(By the way this relates to the last question I asked about the universe expanding)

If the answer to these is yes then what is the difference between object A accelerating away from object B, and the space between object A and B expanding and no matter which is true would it not still be impossible for object B to move faster than light if I was standing on A.
