Hi everyone, just signed up to forum so not too sure of what to expect but can I ask one question that has probably been thrashed to death in the past and it is: Taken that the UV is expanding, what is it expanding into? I was told once that it created space as it expanded but that does not answer the question or I don’t understand it. Also if there are many Uvs are they scattered throughout the cosmos as say Galaxies are scattered in our UV i.e. just 3 spatial dimensions + time? Sorry if my terminology is a bit basic.
