Howling:Bubble universe is e-space?

Could the bubble universe from 'The Doctors Wife' actually be e-space? Or maybe the remains of e-space as it could have been affected during the time war. The rift could be the last CVE that was left open. The doctor does mention the bubble universe is like a plughole stuff falling thru, thats how the CVE's were designed, yes, to suck the entropy thru?

What do people thing?
