This post belongs to the eschaton theme. Which means a small and swift blog post just to do justice to something that can’t be made comprehensively large by any reason, at the moment.
Read the linked news article which giving excerpts from a book by the famed Martin Rees which I haven’t read, nonetheless which sound very tenuous on the scientific merit its purported to be based on, claims that particle physics experiments can create black-hole catastrophes on earth in the very unfortunate event that something goes wrong.
Here is my initial reaction to the article.
Earth’s Schwarzschild radius is less than 1 cm. What that means is earth needs to be compressed into a sphere of that radius with its current given mass, for it to turn into a black-hole.
