Is space impermanent? I know that space is often said to be unconditioned, and it seems right to say that it is empty of svabhava.


But, is it impermanent?
No one done a physics answer yet? 

Here it is. 

Space is impermanent. General relativity shows that space and time are linked together and they change with mass. Mass tells spacetime how to bend, spacetime tells mass how to move. 

The whole field of cosmology studies how the  space of universes changes.
