Who had ‘Lab grown Black Hole?’
“i have become death destroyer of worlds”
I have become hunger, destroyer of tacos.
There isn’t enough mass in our solar system to sustain a black hole, less on a scientists’ research budget.
There absolutely is. Any mass, no matter how small, will turn into a black hole when sufficiently compressed.
I like to believe all that mass in an impossible tiny space is a result of all the multiverses stacked on each other.
yeah but not sustain
Sounds kinda sus
Not everyone can cough up the cash for some free-range organic black hole.
Do we have brandnewsentence on lemmy?
Ahahahah thank you so much I love this
If I read this post without any context I would think “this guy is too poor to hire a black prostitute” and not " this guy doesn’t have a particle accelerator capable of making a miniature black hole"
And this is why you should not skip your physics classes.
I remember seeing Event Horizon.
This won’t end well.
Don’t worry they didn’t make a real black hole, they just did the Supersonic rubidium gas trick
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
Should we be making any of these things a black hole?
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.
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.
I’m pretty sure if we made Jupiter a black hole we’d throw off our orbit and have much bigger problems.
Black holes aren’t vacuums, nothing would change if the mass was equivalent
Yes, but you’d more than likely have to increase the mass of Jupiter to make it a black hole.
Wouldn’t a Jupiter-mass black hole have the same gravitational effects as Jupiter and absolutely nothing would be affected?
Yup
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.
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.
Scientists care too much about if we could, they forget to ask if we should.
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.
I think there was a Simpson’s episode about this.
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)_/¯
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.
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.
So why not just stop beside the planet you are aiming for?
Me travelling calmly through space when a rogue wave of high energy radiation blasts me from some rando warping 2974738 years ago
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.
Hmm, I think you’re right
What about traveling slightly off axis? Could even tack back and forth.
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.
That’s not how that works. It’s not a DnD sphere of annihilation, it’s an infinitely dense point of matter.
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.
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.
But it will still be pulled down by earth’s gravity. And depending on the size, it’s not going to just evaporate if it has a planet’s gravity pushing rock and metal into it.
A high speed black hole would just punch through the earth, but if it just falls down, it would destroy the planet.
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.
Can you imagine what a “black hole fusion accident” could look like?
No, of course not. The accident eats all the light I’d need for that.
I mean, you could imagine it for a moment.
Or would that mean that you can only imagine, because you could never truly observe it?
It would be almost impossible to do something like that without enough fuel though.
In theory you could collapse almost anything into a black hole, every piece of matter and energy has a roche limit
What is that limit for iron and is it referred to as Ferro-Roche?
Did they drop “analogue” or “simulated” from the title?
Did a quick search and yep, it was a collection of rubidium atoms https://www.livescience.com/black-hole-analog-confirms-hawking.html
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.
Maybe not the actual referenced article, but its close:

While the study was testing for a specific kind of energy radiated by an artificial micro black hole…
What’s being glossed over is the broad concept and implications of Hawking Radiation.
https://en.m.wikipedia.org/wiki/Hawking_radiation
Simply put, a tiny micro black hole will evaporate itself out of existence quite rapidly.
There is no danger of such a thing growing and consuming everything like an expanding katamari damacy ball.
We know this because after testing it the micro blackhole did in fact fizzle out. /joke
There is no danger of such a thing growing and consuming everything like an expanding katamari damacy ball.
Damn.
Thought we had an out… Nope we got to tackle fascism and climate change the hard way
Na na na na na na Katamari
Disappointed beyond measure. :(
If only it could suck up a few specific people before evaporating itself out of existence.
Yeah, until we get a micro black hole that’s piloted by a competent Katamari player, then it’s over!
If you can’t grow your own black holes, store-bought is fine.
But it’s not an authentic black hole unless it’s mined with slave labour!
I really prefer wild Atlantic black holes.
Well, yeah.
If you wish to build a black hole from scratch, you must first build the universe.
It’s not that hard, all you needs a little Scots turf builder black hole edition.
I keep hearing commericals for them advertising to kill clover. Always annoys me. If clover grows in your yard, your yard likely needs the nutrients (nitrogen likely). Also, it helps bee populations, which helps well… Life.
Clover was never a weed until weed killer came around out and killed it with everything else in the grass. So they started an ad campaign that told people it was a weed and convinced people that white flowers in your yard look bad.
So now everytime I hear an advertisement that mentions killing clover I remind myself not to buy products by the brand who says it. Also, clover honey is delicious.
No wonder. They’re such a pretty plant, why would anyone kill it off their lawns?
pokes black hole C’mon, devour Earth.
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.
mom can we adopt a lab grown black hole?
