LHC Ad: Beware Bears

You may have noticed an ad running on scienceblogs which says "Has the LHC destoyed the Earth?" If you click on it you find a webpage that says in big letters simply "NO". What's up with that? Check out the webpage source for the page (http://www.hasthelhcdestroyedtheearth.com/). Update 9/12/08: Check out the comments for more fun and also read the cat projectile analyzers take on how you can click to save the world.

Vacuum decay is the ultimate ecological catastrophe; in the new vacuum there are new constants of nature; after vacuum decay, not only is life as we know it impossible, so is chemistry as we know it. However, one could always draw stoic comfort from the possibility that perhaps in the course of time the new vacuum would sustain, if not life as we know it, at least some structures capable of knowing joy. This possibility has now been eliminated. The second special case ... applies if we are now living in the debris of a false vacuum ... This case presents us with less interesting physics and with fewer occasions for rhetorical excess than the preceding one. S. Coleman and F. De Luccia (1980).

There's also an RSS feed should you feel the need to be updated on the status of your own existence.

Wow. Well spotted.

The Coleman and de Luccia paper looks quite interesting, but unfortunately it seems it was published in the days before there was an arXiv and the paper appears to be behind a paywall :-(

I've edited the page so it now points to this one, for tail recursion of a sort...

Daniel Drucker, thanks for that... taking a look at it now.

Viewing the source of the competitor's site,

http://hasthelargehadroncolliderdestroyedtheworldyet.com/

Yields some funny results too:

if (!(typeof worldHasEnded == "undefined")) { document.write("YUP."); } else { document.write("NOPE.");

and

if the lhc actually destroys the earth & this page isn't yet updated please email mike@frantic.org to receive a full refund

Should you feel that text isn't enough and you need to visually monitor the situation:

I was hoping the feed would say "No. The magnet's broken." today.

Heh, I didn't know it was you.
