The size of Star Wars Universe?

How big is it? Is it infinite or it just like our own observable universe(Hubble Volume)?
And does it have multiple universes( Multiverse)?I've read some alternative timelines stories from Star Wars Infinities, I'm not sure alternative timelines/universes/realities have ever been mentioned in canon though

The size of the mainstream galaxy is known, but the the size of the entire SW universe has never been quantified in canon, afaik.

I would assume it's "infinite", but that's just my opinion.

You know the intro right? Some time ago, in a galaxy far far away...

I can confirm. I have the Force.

This, I don't think we know of the universe as a whole. We know there are other galaxies, but nothing more than that.

It would seem that mr. Lucas believes that in the very distant ancient past we were technologically advanced to sci-fi levels.

Still humans, but on a different evolutionary scale.
