The LHC has been turned on and started firing particles at each other.
And we’re still here. Sure, the unprecedented experiments testing entirely new phenomena haven’t started yet, but if the LHC can do the ordinary stuff without making the planet dissolve, then I’m sure there’ll be absolutely nothing to worry about when they do.
Stop laughing and watch the damned screen, you maniac!
Anyway, if it really was going to obliterate the Earth, then where would all the future people returning to try to stop it be coming from?

Just another example of scientists feathering their own nest at the taxpayers teat …
I mean really, who has ever seen these so-called particles that ‘particle physicists’ study’?
This is the (second) greatest scam since the Great Gloabl Warming Hoax emails were released by hac…, sorry, whistleblowers!
I want the data and the related emails so that I can traw.., sorry, audit the results and find the truth.

Hey, I played Half Life, the planet dissolving is the least of my worries!
