How is the universe expanding? And What keeps it expanding?

I’m really curious about how the universe’s expansion works and what keeps it going. A thought crossed my mind: could it be mainly because of the law of conservation of energy?

So far we just call whatever is making it expand “dark energy”, which is something of a placeholder for “we don’t know”. 

If anyone can actually prove anything that answers your question, there’s a Nobel Prize waiting for them.
