CERN: LHC produced black holes could remain on Earth

In the past CERN stated that if microscopic black holes were to be found at the LHC (Large Hadron Collider), they would exist only for a fleeting moment. Today, their definition of a fleeting moment also means all eternity:
"Those produced (micro black holes) by cosmic rays would pass harmlessly through the Earth into space, whereas those produced by the LHC could remain on Earth. However, there are much larger and denser astronomical bodies than the Earth in the Universe. Black holes produced in cosmic-ray collisions with bodies such as neutron stars and white dwarf stars would be brought to rest. The continued existence of such dense bodies, as well as the Earth, rules out the possibility of the LHC producing any dangerous black holes." Reference Link

So to all you people who stated for months there's a chance the LHC could create stable black holes, enough already!
CERN admits it! But no worries, they wont be dangerous... and if you believe that, I have a bridge to sell you!

Next month CERN will admit they're dangerous, but only if you get in the way.

In the topic "Microscopic Black Holes" CERN states "microscopic black holes are not expected in theory". That's not what their people thought back in 2004:

"A spectacular consequence of such a model is the possibility of being able to produce black holes with the next generation of particle colliders. If the centre-of-mass energy of two elementary particles is indeed higher than the Planck scale ED, and their impact parameter b is lower than the Schwarzschild radius RH, a black hole must be produced. If the Planck scale is thus in the TeV range, the 14 TeV centre-of-mass energy of the Large Hadron Collider (LHC) could allow it to become a black-hole factory with a production rate as high as about one per second."
