I love Google's title image for today:
It's a nice mix of recognizing an extremely important scientific accomplishment with just a pinch of end-of-the-world paranoia.
The truth is that the world has about the same chance of ending today as it did yesterday. But I think the dimwitted people protesting the large hadron collider aren't all bad. It's seriously nice to be reminded that the world could end at any moment. All of human history is just a brief blip in time on a cosmic scale; it could end right now and the universe would barely notice. But the thing is, in a universe with a past almost completely devoid of our existence, and a future that could very easily be the same, all we've got are our short little lives here in the present.
The fact that the universe is vast, cold, and uncaring does not make our lives meaningless. It's the opposite; it shows that we are the exception rather than the rule, so we damn well better take advantage of this fleeting gift and make our lives mean something. It also makes it all the more incredible that we are on our way to understanding this vast, cold, and uncaring universe with technology like the LHC. Even if it did end human existence, at least we went out trying to understand our place in the universe. And with a good excuse to have sex.
