Doesn't really matter if there is an answer or not. We can view it however we want. Those are opinions.
Does a tree make a sound if it falls and nobody is around to hear it?
Well, do you believe it does? I do. Somebody else doesn't.
A real question that dosn't have an end might be:
How many numbers in the number pi? Well, a computer has been calculating this since the 80's and there are still numbers coming out. Quite possibly, there is no end. But, somebody else probably thinks otherwise. Unanswerable questions are opinions. All questions have answers. Its just a matter of creating an answer that we like.
(Does the universe have an end. I would hope so... But the real question is if there is an end, what lies beyond? That again, is all up to your opinion).

Huh? A sound doesn't have to be heard to exist. The vibrations still travel through the air, possibly knocking something off a branch or whatnot. Even if nobody's there to hear it, it was there.
That's like saying air doesn't exist because you can't see it.
Actually, that is untrue. Observation changes the outcome of everything. Light when being viewed is a particle. When it is not observed it is a wave.
Just like if nothing hears the tree fall it might not have made a sound. Nobody knows because there is a possibiliy out of the endless possibilities that is didn't make a sound.
Just like, if you walk away from a waterfall until you cant hear it anymore, it might not be there because out of the endless possibilities all of the atoms and everything of the waterfall might disappear or decay and the waterfall would be gone.
If you are not observing something then everything possible is happening at every moment in time. Right now, in space, where we aren't observing some light, it is everywhere and every moment in time until we look at it.
Its very hard to wrap around your head, but thats how quatum mechanics works. But, I guess it really depends on if you believe in quatum mechanics or general reletivity.
