CERN activated the LHC a little over an hour ago. Looks like we're all still here, so happy LHC day everyone! (Famous last words?) :P
I was lucky enough earlier this year to enter the LHC and have one of the last tours of it (once activated, it is too radioactive for people to venture in). Watch a video of the tour (and part II) that Robert Scoble shot on the day and play "Spot the Aral!"
It was an awesome day, we had Ben Segal along — (plug, plug) he's speaking at the <head> web conference — and he took us on a personal tour afterwards to show us the computer that Tim Berners-Lee created the first web server on... ah, memories!

See, it’s not the end of the world ;-) That won’t happen *until* they’ve callibrated and begin smashing particles.
Seriously, though, this is a big day all round! Lets hope we get to prove String Theory (or at least some of it).
Oh, another point. Check this out :

For those wanting to know more about String Theory, there are some really good videos, here :

(make sure to watch them from top to bottom, not left to right. There are three one hour episodes)
Cheers to that! I’d listen a cup of Dopplereffekts newer stuff to it!
Oh, another point
Oh, another point yes yes yes
