Is there a way to "see" beyond the observable Universe?

I understand that the observable universe is simply light that has had time to reach us, and that without such we cannot really observe outside of it. I was wondering if there's any theoretical means by which we can extend our vision, so to speak?

No. That would require something to propagate faster than light, and nothing we know of does that. The closest thing we can do is see the effect of as-yet-unseen objects on what we can see, so it's a sort of "seeing by proxy" effect. Dark flow is an example of this.
