      This is a difficult one…I think the most interesting one I’ve found out is that according to some models of the universe, there’s a chance that a small bubble could appear, where the laws of physics are different. This bubble would expand at the speed of light until it covers the entire universe, and it would probably destroy everything in its path! It’s both an interesting fact and a scary one — but luckily we believe the probability of this happening is so tiny we don’t need to worry about it. And besides, if it expands at the speed of light we won’t know anything about it until it hits us, so there’s no use worrying anyway!
