So what exactly does this mean for us Hana, cause you know I'm not a physicist? y:(|)
Does this prove a beginning?

I will quote:

When asked to comment on the implications of this discovery, Harvard theorist Avi Loeb said, "This work offers new insights into some of our most basic questions: Why do we exist? How did the universe begin? These results are not only a smoking gun for inflation, they also tell us when inflation took place and how powerful the process was."

So does this mean without a doubt there was a beginning to the universe?
Or is this just evidence for the current model?

They claim it is smoking gun for inflation. Not necessarily for beginning of the universe. Some theories say, there were more inflations, more beginnings and ends. Now scientist can study details of detected gravitational waves and rule out some theories. So the big thing is, there was inflation and that we can study details and rule out or support theories about our universe.

Sweet, just another piece of the puzzle hey.

It is expected that Nobel prize will be for this discovery.

I was going to post about this before I saw it already here. I'm on Spring Break, but lots of my friends are talking about this considering one of the professors at my university is a co-leader of this project (so it's a big deal for our school in general). Pretty cool stuff.

A great discovery to support the Standard model - but I would disagree that it would answer the question "Why do we exist." Science cannot answer that.

I think "why" we exist in this context is not our purpose for existing, which science can't answer. I think "why" we exist in this context, is more of a cause type of why. Why do we exist? We exist because the Big Bang caused x to form, which eventually caused the necessary elements for life to exist.

It basically cements the inflationary model as the standard model. If anyone deserves the Nobel prize it's Allan Guth, the father of the inflationary model (and the 'G' of the BVG theorem). While this discovery does not answer the source of the singularity prior to the big bang, the BVG theorem certainly helps in stating that any inflationary model is past incomplete (had a beginning) no matter the number of singularities (i.e. it rules out an infinite mutli-verse).

The conclusion is really inescapable but let's see how it gets spun around.

Why are a lot of scientists saying at the moment that this discovery is pointing to a multiverse?

I personally have not heard that yet, and don't necessarily see where this evidence points to that at all. Did you read an article about it?
