    Hopefully they can finally manufacture black holes. Because that would be totally safe for everyone 😉.

      There are plenty of natural particles colliders, such as black holes or very dense stars, that are way more powerful than our engineered particle colliders, which (observationally) don’t create black holes around them

      Well no danger of that. We certainly cannot do it on terrestrial scales. No way, no how. Not even with fusion and a collider ring wrapped around the equator. It still requires vastly higher energies.

      Even if we could make a kugelblitz black hole right here, it would instantly fall out of reach through the Earth while barely interacting at all with any other particles. On the Planck scale, particles are mostly empty space. We wouldn’t even get to study it.

      The best way to build one is to surround a star with millions of orbital mirrors, then focus all the light onto a single point in space, with an accuracy of nanometers, if not picometers. Focusing enough energy on a single point will cause a tiny black hole to form. It’s probably impossible to do by accident.

      They posit that yes, black holes could be formed, but they’re so small they evaporate pretty much instantly. They don’t have the mass to survive.

      Similar reactions produced by particle accelerators are constantly happening all around us, and isn’t just limited to extreme conditions like around black holes. This is just the same thing but at a much smaller and more controlled scale, and last I checked the sun hasn’t produced any world ending black holes despite the far more extreme reactions constantly happening within it. A man even survived a high energy proton beam from one of those accelerators passing through his brain and was able to continue his career in quantum physics, so at that point I doubt they’re capable of anything world ending.

      Don’t worry! Though black holes may sound scary, microscopic black holes, the type that could hypothetically be produced by high-energy particle collisions such as this, would pretty much instantaneously (in approximately 10-27 seconds) evaporate due to the emission of Hawking radiation, before they could “suck up” anything. Cosmic rays of far higher intensities than what we could produce routinely collide with atoms in Earth’s atmosphere, so microscopic black holes could be happening daily in our atmosphere, we just never see them because they’re far too small and evaporate instantly.
