What's our Best Guess on How the Universe is Expanding?

I understand why its accelerating in expansion ('understand' as in understand what we've reasoned so far) but what's our best guess on how the universe originally expanded? Are vacuum fluctuations a possibility?
I try not to stress about it !

Ha ha, I wish I could, but the question's been tugging at me for quite a while.

Oh that is such a high-class question compared to many on here. Thank you! As for the answer, I ascribe it to the Goddess beginning to dance, but I think you were looking for something more sciency :)

Well, thank you, ha ha. :)

Why is it accelerating in expansion? Shouldn't it slow down?

@Animore: and how come you seem to know so much about science at such a young age?

Well scientists have actually discovered that as the Higgs Particle reaches a critical value, gravitational waves get sort of enhanced in a way. (https://phys.org/news/2014-08-higgs-boson-earliest-expansion-universe.html)

But this is theoretical, and we still have much to learn about it. But if it's true, and if there's a correlation behind the increase in expansion of the universe and the Higgs Particle, that means that the Higgs Particle really does have a false vacuum, and we could all die from Vacuum Decay. Frightening thought.

And thank you, ha ha, I just enjoy learning. I used to not really like science, but then I started getting into astronomy, and that's what got me interested. Cosmology is my main focus. I enjoy talking about the birth and death of the universe. It's frightening but captivating.

It's frightening but captivating. Absolutely true.

It all started off with the big bang and has been moving outward ever since

@Paschar: Well yeah but that's exactly my point. We know they exist, and that they can create energy out of nothing. We can observe them at Hawking radiation as well, so wouldn't it be possible?

@Paschar: I don't need an explanation, thank you, I understand the concept of the expansion of the universe. I wish for an answer to my question.
