No, the problem is not that the sharks will choke on Bin Laden's poisoned heart, it is that the lack of a body will only encourage conspiracy-mongering. I'm reasonably sure that the birthers and the truthers will soon be joined by the Abbottabaders, or whatever they're going to be called. We're waiting, of course, to see what, if anything, Ayman al-Zawahiri, the new al Qaeda number-one (mazel tov on the promotion, by the way), will say about the death of his putative leader. If he acknowledges the death, then the conspiracists will have more trouble ginning up anxiety. Which won't stop them, of course. See: Trump, Donald.
Light pollution has taken away our ability to see the stars. Can we still save the night sky?
