    Don’t buy lab-grown black holes, it’s not quite the same if it’s not mined by a child in South Africa. And it should cost at least three times your salary, otherwise your spouse will be ashamed.

      It’s only a black hole if it comes from the black region of space. Otherwise it’s just a sparkling dense mass.

    Us developing an actual black hole would be one of the best things humanity has ever done. It would kinda be like inventing techniques to make fire.

    We could throw shit around the orbit of the black hole and get fusion. Not just deuterium fusion! Even proton proton fusion. Our energy needs would be solved practically forever.

    We could conduct a crazy amount of experiments on the black hole, see quantum effects of gravity and whatnot.

    Maybe we could build one of em Alcubierre drives that don’t need exotic matter?

      Pretty sure any black hole we create would evaporate from hawking radiation before it could be used for anything outside of research.

        If we could make Jupiter a black hole, would that be stable enough to not radiate away? Other big body we have access to is the sun and I feel we would suffer more side effects of turning that into a hole compared to Jupiter

            The sun is debatable, since I think we already use it’s photons both for photosynthesis in plants, heat (although we could get infrared warmth from the hole) as well as other benefits

            Why shouldn’t we holify Jupiter? It would be a testament to our technological progress as well as helping us study black holes "close"ish by rather than in labs

              Sometimes our technological progress makes us do things we think are a good idea at the time. Then like years, decades, centuries, millennia later we realize it was not such a good idea after all.

          I’m pretty sure if we made Jupiter a black hole we’d throw off our orbit and have much bigger problems.

            Wouldn’t a Jupiter-mass black hole have the same gravitational effects as Jupiter and absolutely nothing would be affected?

              If you were very, very close to it, not exactly, since Jupiter’s mass is more spread out, making the gravitational pull slightly weaker at close range. But for practical purposes yeah nothing would change for us other than space debris being flung around it instead of hitting it.

              My point was more that we’d probably have to increase the mass to be able to make it a black hole, as we don’t have the ability to compress it to a singularity.

      One of the first things we will use it for is to make a new weapon of mass destruction. Mark my words.

      Tiny black holes are the kind of thing that physically cant exist for more than a few like picosecods or something ridiculous like that before evaporating into radio waves.

        We kinda don’t know for sure though. The tinier the black hole gets, the more it enters into the realm of quantum mechanics. We have no clue how quantum gravity works, so ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

          Pretty sure the whole point of this article is we have confirmed tiny black holes do rapidly evaporate. We’ve theoretically known that any black hole just about our sun’s mass or smaller will spew more Hawking Radiation than it can consume mass and will shrink. And this process should accelerate as the mass shrinks. This seems to be the first expiremental evidence to support the well established theory.

      It’s wild that there is so much space between atoms (and inside them, between the elctron orbitals and the nucleus), and black holes are so incredibly dense, that a small black hole can fall all the way through the Earth and not hit enough matter to gain appreciable mass.

        You got any links to explain this in some more detail?

        Because this just causes my brain to jam when trying to comprehend…

        Like what diameter of black hole are we talking?

        And what is the critical mass of the black whole before it starts to cascade and grow?

    There isn’t enough mass in our solar system to sustain a black hole, less on a scientists’ research budget.

    I was a black hole analog built out of Bose-Einstein-Condensate.
    Considering they used sound instead of light, wouldn’t that make it a silent hole?
