Large Hadron Collider : Is it safe?

This thing could reduce earth into a Golf ball, as some people say. Really?

On the news today:

The world's largest particle collider passed its first major test by firing a beam of protons around a 17-mile (27-kilometer) underground ring Wednesday in what scientists hope is the next great step to understanding the makeup of the universe.

Some fears about this project are:

1. “Honey, I shrunk the earth!“

2. In order for Earth to be in danger from micro black holes, the following would need to be true:

# Micro black hole creation — Unknown, predicted by some physicists.
# Hawking Radiation failure — Unknown, challenged by some studies and polls.
# Rapid growth of Micro black holes — Unknown, predicted by some theories.

Cosmic ray impacts do not prove safety because results of cosmic rays pass through Earth and into space at nearly the speed of light. If colliders can create micro black holes from head-on collisions, some percentage will travel too slowly to escape Earth’s gravity.

3. Just like the managers that recommended Launching the Shuttle Challenger did not believe that it would explode. They knew there might be a reasonable risk because their engineers told them there might be a reasonable risk. But the managers said (paraphrase) “there is no proof of reasonable risk… launch!”

4. Besides many theories and Nobel Prizes relies on running the Large Hadron Collider!


A comment I got from

negligible?!?!?!? seriously? we could all die for godsake. I think this is dumb and there’s no point in it. maybe the LHC should leave the world alone, and not try to kill it off for once? I mean, this is the whole world for love of god! not a town, not a city, not a state, not a country, THE WHOLE WORLD!! that’s like 4.5 billion people. think with the practical part of your brain instead of the nerdy must-prove-we’re-smart part.
