"creation of space" what exactly does this mean
dear all,
I must admit, the wording "space is created" sounds to me rather unscientific (forgive me for being provocative). I know that, in general relativity, there are (more or less arbitrary) reference frames and distances within these reference frames. In terms of reference frames, distances and geometry: what does "creation of space" mean? Does it mean that a new reference frame is created? That wouldn't make much sense to me. Is it a synonym for "expansion", i.e. the fact that distances between stationary observes increase? In that case, I don't understand why people say that during the big bang, space was created alongside matter. This would imply that space was created only in the very beginning, while expansion still takes place...
can you help me?
