Something Terrifying Could Happen Inside CERN

Fexl | May 10, 2026



A microscopic black hole created at the LHC, with a mass measured in a few teraelectronvolts, would exist for an almost impossibly short amount of time. Current predictions put its lifetime at about ten to the minus twenty-seventh of a second. That number is so small that, in that entire span, light would not even travel the width of an atomic nucleus. The black hole would disappear before it could meaningfully move, fall, or interact with anything around it. It would simply flash into existence and vanish immediately.

If these tiny black holes can form during high-energy particle collisions, they would not stick around or consume matter. Instead, they would evaporate almost instantly, releasing a sudden spray of particles as they disappear.

    If you are slamming two protons together and they make a black hole it will disappear instantly plus the black hole will be so small it couldn’t hurt anything.

    This is silly. The things that happen in CERN happen naturally right over out heads at the top of the atmosphere and it happens at much higher power than CERN could ever do.

    This project assumes that the Standard Model is correct. The Multiverse says it is not. This is because, Quarks, Leptons and Bosons do not evolve into Protons. Quarks etc. are produced when protons are split apart. Now the big reveal. Dark Matter particle, Torus Strings, are what evolve into Protons, not QLBHF particles. Don't believe me? check out "The Multiverse Theory." There is tons of new evidence to explain why this is not only possible, but probable.

    After all of my observation and research, I have come to determine that temperature, especially at this scale will change everything. Let's say they decrease the temperature to about the temperature of that that they use quantum computers now that would change everything. Because as we have observed all of the matter and particles function very differently under that type of temperature. So if you were to take these particles and collide them under that type of temperature well I think interesting things would happen. Don't know what would happen. I don't think it would be negative but I also think it would help us really better understand physics. Some things that we just can't quite get but almost.

    If you could create a black hole then the mass would have to be no more than the energy used to create it. While the LHC may look big and impressive and it takes a lot of power to warm it up, the amount of energy when particles collide is minuscule. And if a black hole did get created, it would be so small as to be meaningless. What is the diameter of the event horizon for the energy of the collisions in the LHC?

    yes. we don't understand the universe.
    yes. we need to explore.
    yes. it's dangerous, so is sailing a ship across the ocean.
    yes. we're playing with ELE, get over it.
    a blink and nothing forever.
    maybe you'll be lucky enough to see the end.
    entropy will win.

    “The time will come when diligent research over long periods will bring to light things which now lie hidden.
    A single lifetime, even though entirely devoted to the sky, would not be enough for the investigation of so vast a subject…
    And so this knowledge will be unfolded only through long successive ages.
    There will come a time when our descendants will be amazed that we did not know things that are so plain to them.”

    The LHC makes 6.8 TeV particles. Cosmic rays of 244 EeV have been observed, 40 million times more energetic than the LHC. LHC level of energy cosmic rays hit every square meter of earth about every second.

    Gravity isn't weak, but it uses that extra energy to shape the space-time background ut tra els through. It's similar to the ADD model but removes all those extra curled dimensions. Similar to how a trillion gausse or Teslas will cha get the state of the matter in its field.

    That's always been the problem with our understanding of gravity, despite how Einstein changed it from newtonion physics….it's why the 2 fields won't join, and infinities start showing up..

    Every time I hear how "weak" gravity is, I think WTF? It warps space and time. A certain amount in too small a space and it totally stops light from escaping and creates a space effectively separate from the rest of the universe.

    This is terrifying! [less shouty:] "Something terrifying could happen…" Good way to start an ostensibly scientific vid with a healthy dose of clickbait followed by weasel words. Should I bother watching…?

    A Scientist's Tiny Black Hole Brings the Cosmos Into the Lab
    Single-purpose quantum computers are helping physicists build simulations of nature's greatest hits and observe them up close. Inside his lab in Israel, Jeff Steinhauer crafts microscopic black holes. These objects are but humble specks, lacking the spaghettifying suction strength of an actual dead star. But Steinhauer, a physicist at the research university Technion, assures me that he’s constructed them mathematically to scale. Zoom in far enough, and you’ll see a miniature event horizon restaging the drama of a true black hole."

    I wish this was true somehow considering no real microscopic black holes have been created or observed in any experiment if would have a ability to make microscopic black holes could be useful probably for physics if that is possible as this could be useful, but probably nope haven't probably created any black holes thus far, unfortunately.
