  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

      Should we be making any of these things a black hole?

        Replacing Jupiter with an equally massive black hole shouldn’t make a difference. We’d only have one bright dot less in the night sky.

        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

      If Jupiter was compressed to a black hole it would be 2.8 metres across and would last longer than the Sun

      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?

        Black holes aren’t vacuums, nothing would change if the mass was equivalent

      Scientists care too much about if we could, they forget to ask if we should.

  Yeah.

  Then somebody drops it and it just falls down to the planet’s core and eats our fucking world.

    The way we are going, its for the best

      I’m not saying we shouldn’t do it.

    Ok, so even if it “falls down”, it will probably evaporate way before it even reaches the center. Even if it doesn’t, it will be take A VERY LONG TIME for it to get big enough to eat the planet out or whatever.

    It is very VERY difficult to make something fall inside a black hole. Mostly, stuff just zooms right past it at incredible speeds.

    The earth would be consumed by the sun way before it gets consumed by a black hole.

      You’re talking at scales where the incoming mass has a lot of velocity already. In a stationary frame of reference, the matter would more than likely fall directly in since there isn’t an appreciable amount of rotational momentum involved like there is at stellar sizes.

    That’s not really how black holes work. They evaporate really quickly when they’re small enough. And if they’re small, they don’t have much gravity either.

    We'd have a quasi-planet.

    That’s not how that works. It’s not a DnD sphere of annihilation, it’s an infinitely dense point of matter.

    source

    • Asetru@feddit.org ⁨3⁩ ⁨days⁩ ago

      That shrinks in a vacuum but grows as other matter gets too close. Matter such as “the earth”. Explain how we’re not fucked if it escapes from its magnetic vacuum suspension because Kevin accidently drops it.

        There is a surprising amount of empty space between atoms, and even inside atoms between the eleftron orbitals and the nucleus. Small black holes are so dense they mostly fall through this empty between-atom space and don’t actually hit anything. Even in a matter-rich environment like inside the Earth, you’d need a black hole with more than half the mass of the moon to be large enough to eat matter faster than it loses matter to Hawking radiation.

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

    It would make whoever controls it effectively God, so yeah - probably.

  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.

  source

  • UraniumBlazer@lemm.ee ⁨4⁩ ⁨days⁩ ago

    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.

  Unfortunately an Alcubierre drive dumps a shitload of high energy radiation in the direction of travel when it stops. We would sterilize every world we get to.

    So why not just stop beside the planet you are aiming for?

        Wouldn’t that be a non-issue? The radiation is going to be spreading out in a cone, not a focused laser beam. It should dissipate down to a level that a spaceships normal radiation shielding would already need to be able to handle pretty quickly.

    Isn’t that a solvable problem though? Overshoot the target planet by just enough, that it isn’t in the hemisphere of the warp bubble pointed towards the direction of motion.

  I think there was a Simpson’s episode about this.
