Active Directory Group SID

Active Directory Group SID

I have read online that SID  and GUID  are created whenever you create new object in Active Directory.
SID is only unique in its Domain , GUID unique in its forest and even world wide.
Not sure how GUID uniqueness is controlled world wide ?

For SID if it is user object and it is moved out of the domain, its SID will change.

What about the SID related to user Group, will that be changed if it is moved to another Domain ?

Thank you
