Theoretically, there are not supposed to be any particles in a vacuum. It's supposed to be the absence of anything. Yet, while light can travel through "nothing", it was still being interfered with. The only way to explain the interference was by the energy produced when these subatomic particles popped into existence very briefly, and (according to theory) collided with its anti-particle and destroyed. So what the scientists were beginning to realize was that these tiny events were happening all the time, in what we previously thought was empty space. So in a grand scheme of things, this suggests that not only can something come from nothing, but that it happens all the time and is a practical fact of nature.
Anyway, I'm not sure if that's what you were referencing, but I thought I'd talk about it anyway, as it's pretty interesting stuff.

Yes this has been observed which could lend credence to the big bang theory in that there truly was nothing to begin with but particles 'borrowing' from their negative self's.
I think that until things like dark energy and anti matter are actually figured out, we are still a long way off from many many answers.
I have noticed religion being mentioned in posts and that is inevitable regarding this subject as we are no closer to a definitive answer (if ever) to the eternal question but I will abstain from any religious debate within this thread as I am much more interested in the science and physics aspect but by all means - talk amongst yourselves!
This doc is excellent as are most of the others collected by the same user and well worth a watch if you get the time:
