I wonder sometimes... Even last night as I was blitz'd, is t possible that the sky is simply a large television-esque dome above us and the nature of our universe is a lie?

Certainly possible as so much of what I know about things beyond the atmosphere is second hand knowledge. What's the motive? Not sure, but lack of knowledge of a motive doesn't change the fact that a crime has been committed =)

My biggest question would be who built the dome and what happens on the other side? And if I flew high enough with my AK-47 in hand, could I shoot a hole in it?
