“Universe” is often used in the sense of “observable universe”.
- jinwoo68 2y agoI don't think the paper claims that it's the observable universe that rotates. Does it? It'd be awkward if only the observable universe rotates. Observable universe is not special. It's observable just because it is "close" to the Earth.
