One of the big headlines in the news right now is the launch of the Large Hadron Collider at CERN in Switzerland. The facility is meant to accelerate and collide subatomic particles in order to recreate conditions that were present at the start of the universe so that the interactions of these particles can be studied.
One of the (somewhat ridiculous) concerns coming out of this experiment is that the collision could cause the end of the world (by creating a black hole, or god knows what else). While this concern has been thoroughly refuted several times by people more qualified than me, the folks at Reddit and Fark have taken a different approach to addressing them.
Sound advice, all things considered.
