The Large Hadron Collider was turned on today, and despite the concerns of some "skeptics", the world did not end. Which I'm pleased to hear, obviously. I don't have enough scientific expertise (which is to say, I have none at all) to doubt the assurances of all the scientists who assured us the experiment was perfectly safe. I did, however, observe that the manner in which the scientists responded to these concerns reminded me of every sci-fi plotline in which scientific hubris/overreach causes the downfall of human civilization.
Thankfully, the universe is neither ironic nor interested in literary cliches, so we're good. For now.
