    Here we go again: Cern black hole could destroy earth

    This story keeps coming up: https://www.newsweek.com/earth-shrun...rators-1145940

    There is a very remote possibility that Earth could be reduced in size to a “hyperdense sphere” measuring just 330 feet across—the length of just two football fields—by particle accelerators like the Large Hadron Collider (LHC).The U.K.’s astronomer royal, Lord Martin Rees, has explained this risk in his new book On The Future: Prospects for Humanity, which is due for release at the end of October. In an interview with The Telegraph, Rees discussed one particular chapter that deals with the potential dangers of physics experiments where particles are collided at high energies.
    "Maybe a black hole could form, and then suck in everything around it,” he says, according to the newspaper. “The second scary possibility is that the quarks would reassemble themselves into compressed objects called strangelets. That in itself would be harmless. However under some hypotheses a strangelet could, by contagion, convert anything else it encounters into a new form of matter, transforming the entire earth in a hyperdense sphere about 100 metres across.”
    I thought this story was long debunked years ago...

    Cosmic rays would have done it to us long ago if it could be done. Human efforts are, as always, wimpy by comparison to what ol' Mama Nature can do.

    Article from 2008 about attempt to stop LHC from destroying Earth. I recall it was Chicago's Fermilab that was going to destroy the Earth before then. Still waiting for it to not happen.

    2007 New Yorker article that mentions a 1999 paranoia about Brookhaven doing the same thing. Nothing is ever new.

    A 2014 story about this from PBS

    When the Large Hadron Collider (LHC) began operations, a small but noisy group of people tried to stop it out of fear. Their reasoning: The energies produced as protons slammed into each other at close to the speed of light would be sufficiently high to create miniature black holes or other exotic, destructive things. The fruits of human curiosity would be the literal end of the world.

    Those fears were unwarranted for a simple reason: Earth is bombarded by much higher-energy particles all the time, and we haven’t been eaten by a planet-munching black hole yet. In fact, the universe has many naturally-occurring particle accelerators that are far more powerful than the LHC, exceeding even anything we could build in the foreseeable future. Anything exotic we can create in our labs, the cosmos has beaten us to it.

    ...

    “The energy for particle creation … in the upper atmosphere is more than a factor of twenty greater than at the LHC,” said Glennys Farrar, professor of physics at New York University. Most impressive of all are “ultra-high-energy” cosmic rays, which reach energies 100 million times greater than the fastest protons produced in the LHC.

    There is a really funny program about this. I'd definitely recommend it.

    It's a coverup! The LHC actually destroyed the world a couple of years ago but the PTB's aren't telling us to avoid panic.

    Hey, it's no sillier than most of the other popular CT's!

    Particularly back in the day when we had a lot more CTers, I always thought that should be CQ's theme song.

    But the black holes from cosmic rays are natural black holes. They arenít as dangerous as the artificial ones. It you think that, I have some mushrooms for you....

    Yes, I only like all natural, free-range black holes.

    I totally know the feeling. Just make sure there is no dihydrogen monoxide in the stuff she puts on!

    Some science-fiction stories about strangelets destroying Earth... nice to see that SF has all the bases covered.

    I am pleased to see no one has castigated Lord Rees for speculating on the possibility. After all, the poor chap has a book to promote.

    I think he has every right to say it though I think itís a tad irresponsible considering his position. I think itís unfortunate that he is taken so seriously on this. Heís a cosmologist, not a particle physicist.

    The very fact that Cosmic Rays slamming into the atmosphere dwarfs any particle collision on Earth is enough to debunk any doomsday theory.

    But the thought has crossed my mind, what happens when far in the future our particle collision experiments reach energy levels that dwarf THOSE cosmic ray collisions?

    We just do them far away, like in orbit around Pluto

    By that time, we'll have options besides Earth.

    NO! Nibiru will pull it out of orbit and send it to hit the Death Comet and Earth will be destroyed!

    I hope.

    Where in the universe would we run to escape a vacuum decay? We wouldn't even see it coming!

    Realistically, it's very naive to think mankind can destroy the universe. Pretty sure there's energy levels reached in extreme areas of the universe that no machine will ever achieve, like quasars. The fact that we can see them with light means no vacuum decay event went along for the ride, so we're safe playing with our own toys.

    If that happened it would just be replaced by something even more bizarre and inexplicable.

    We'd probably need an accelerator ring the diameter of the orbit of Pluto, anyway.

    The highest energy at CERN is 13 TeV. The oh my god particle was 10 to the right TeV. Itís ten million times stronger. Iíd say the likelihood is that we will never go there.
