1. nature’s constantly doing way more than the LHC. cosmic rays are much more powerful than anything that will happen at the LHC, so if anything was a physical possibility, it would have happened in the cosmos. and we would have known about it.
2. physicists have families, too. There are thousands of people working on the LHC all over the world, and if they saw this sort of a threat they’d not only speak up–they’d be screaming about it. I’ve worked with particle physicists, and believe me, they don’t “throw caution to the wind.”
3. Third party physicists were assigned the duty of thinking of ever possible scenario, conceiving of anything that could possibly go wrong, and still couldn’t come up with any scenario that actually suggested that there was any sort of a danger.

This is all a result of a misunderstanding, of taking scary words like “black hole” out of context. I encourage you to learn about particle physics and the LHC and get excited!! The Irvine Spectrum will be here for decades to come, I promise.
