I recently saw a live on TikTok talking about a recent article about the LHC on how it might cause the apocalypse and the person hosting the live straight up said "I don't understand any of this but.." and I moved on because anything they had to say was going to be some of the dumbest things I've ever heard.

People will really drive around in free moving engines powered by thousands of controlled explosions while thinking scientists playing around with particles dont know how to not destroy the universe.

This post was made by particle collider gang.

To be fair, some pretty prominent scientists and engineers weren't 100% sure the first nuclear tests wouldn't ignite the atmosphere.

They were pretty sure, but not completely.

As I understand it this is only partially true, and although it was a concern they ran the numbers a bunch and found it wasn't possible. They weren't actually willing to go forward if it was even slighty likely. Of course, you can't always be 100% sure of anything in life, and scientists tend to point that out a lot when declaring stuff.

For another example, you can mathematically prove that, within our physics modeling of the universe, that gravity won't turn off tomorrow. But can you prove it prove it? Not til tomorrow. However, despite this, you'd be hard pressed to find a scientist who would think gravity turning off is something to be worried about, despite an inability to prove it won't ahead of time with 100% certainty.

dont know how to not destroy the universe.

I mean... I'd hope they at least have some theories on the subject.

There is some reason why we see no other life in the universe. Maybe other species out there are black holing themselves? Probably not. Odds for war or climate destruction being the cause are much higher.

Advanced life might also be incredibly rare, like - one per galaxy or less, and there may be no way to cross between stars. It's impossible magic. The aliens are just too distant to detect. That's my guess.

Or they're keeping us as zoo animals / pets and we occasionally spot them on the radar, and then they just scoot away at Mach 20. That's also a likely scenario.

Yup. My bets are on distance and FTL travel actually being impossible.

I like the grabby aliens hypothesis.

Basically even at sublight speeds it would only take a few million years to colonize the galaxy. Any species that's likely to do so would inevitably alter the evolution on the planets they colonize as an unintentional byproduct of being there. Any species that wants to actually go through the trouble of sublight colonization would also be one that's expansionist and wants more territory, and would have done similar to what we've done on Earth to their homeworlds, colonizing everywhere habitable and generally being "grabby" about resources and land.

Because of this, no intelligent life is likely to emerge in the galaxy after colonization kicks off in earnest. So the only species likely to be smart enough to actually look at the sky and wonder if they're alone are likely to be this early set of species that evolves pre-colonization.

In other words, we don't see anyone else at this party because we got here early.

That's a more optimistic take at least. Better that we got here early than that countless species out there annihilated themselves in myriad ways. I like that option better, but am not certain I buy it.

It's not a silly question. There are plenty of unknowns. The LHC particle-collisions are millions of times as intense than anything going on inside your car engine. It's at least possible the scientists are on the wrong track about the details in there..

No there is literally zero chance that any particle collisions at the LHC will create anything close to a black hole. In order to create a black hole, enough mass would have to be compacted into an area small enough to create an event horizon (its Schwarzschild radius), and for something like a proton that would require compacting the proton's mass into a size so small that it would be far smaller than the Planck length, which according to the equations is literally the smallest measurable size. We are far far away from the energy required to do that. The LHC would need to be closer to the size of the entire solar system.

Unless M-theory is correct, in which case gravitational strings would be far stronger on a minute scale, and therefore capable of creating miniature black holes that disappear milliseconds after their creation.

The collisions aren't more intense than anything constantly happening in the upper atmosphere, so there's that

True, but they're not exactly the same as what's happening in the upper atmosphere. There's enough vagaries in the science that people can be anxious about it. If they did create a black hole or a neutron-object the size of a molecule, would it inevitably swallow the earth eventually? They say it's impossible, but I just don't know how much certainty they have on these things.

Black holes decay. And creating one the size of a molecule would take ungodly amounts of mass and energy.

The 'I don't know how much certainty they have on these things' should read 'I don't know much about these things.'

OK. They do supposedly slowly decay. They also swallow mass and matter.

Could you guarantee that they'd decay faster than they'd grow?

Your premise is that all this science is completely well-known and guaranteed harmless. Is there even a 0.1% chance there's more to it?

Didn't they just discover a 5th force of nature a couple years ago? That was unexpected. Maybe there are more unexpected details like that out there.

'supposedly' isn't 'supposedly' when we've literally observed it occurring. A black hole the size of a molecule, not exposed to mass, has nothing to consume (the lhc operates in a vacuum). Tertiary, you're completely ignoring the inability for us to even create these things due to the energy required.

I know that much-higher-energy events happen all the time in deep-space, and we get supercharged particle collisions from those events in the upper atmosphere. But then there are videos about 'quantum tunnelling' events in relation to cosmology, where very rare unexpected things can happen. It just seems like it's worth some attention.

But you've put me at ease. I can see that you have multiple PhD's so let me ask a couple related questions.

IF we did accidentally somehow make a micro-black-hole - in the vacuum chamber - how could we ever keep it in the center of the chamber? Are you supposing that we could manipulate such a thing with magnetic fields? Why wouldn't it instantly just fall into the earth and start swallowing matter? Please elaborate.

It just seems like it's worth some attention.

You've just thought up something with no knowledge of the subject, which is fine and good, but the problem is that you go on to assume nobody else has thought about it just because it's new to you. The people working at the LHC absolutely do have "multiple PhDs" and they have indeed thought about this. Instead of demanding satisfaction from a random Redditor, you could look that up.

Like, you mention quantum tunneling as an "unexpected" event. It's counterintuitive to laypeople, sure, but it's a very well-understood phenomenon that's not at all "unexpected" to physicists since at least the 60's if not earlier. It's part of undergrad physics curricula.

Basically, "quantum stuff is weird" doesn't mean "anything could happen." There are a lot bigger things to worry about, like how were demonstrably destroying the things we depend on to live though much more mundane means.

OK. Thanks for the link. You sure brought out the worst of you character, but thanks nonetheless.

I get that they say they can't be created by the LHC. I don't see anything in there that says we're safe if a tiny black hole did in fact find its way to earth. As far as I can tell, this says we'd be toast. Can you interpret all those equations? Give it a shot.

Thankfully I don't need to because they've already done the interpretation for you right there in the abstract. "A tiny black hole finding its way to Earth" is completely different than the LHC destroying the Earth, which is what the conversation was about, but they do address that. If it were a real concern, we'd see neutron stars and other dense objects getting eaten up by the same process. Which we don't.

If it's "the worst of my character" to point out that you're being presumptuous by assuming nobody's thought about this and demanding explanations from random Redditors, I think I'm doing okay. It's good to think about this stuff, really, just please have some humility about it instead of just angrily asserting things and challenging the internet to prove you wrong.

The less massive (and the much smaller) black holes are, the quicker they "evaporate" via Hawking radiation

IMHO, I think it's awesome. It reminds me of one of the watercolor illustrations you'd find in a middle school text book or as a massive painting hanging in the lobby of the new headquarters after the "incident." Great work and a perfect fit for this sub.

There is the fermi lab building in the background (spoiler, that’s not where the lhc is)…

It is also to small and not mountanous enough for the LHC

the terrain fits pretty well not all of switzerland is mountainous

as a swiss person who has been in the region before... It doesn't fit. It really doesn't fit.

Because while not all of switzerland is mountainous it's all rather hilly. If you ignore the fact that you should either see the Crêt de la Neige or the lake geneva with the alps in the background.

And you need to ignore the american style suburbs which are just not a thing here...

[deleted]

... if you ignore that that's in batavia illinois... which is as you might have guessed not in switzerland and not the lhc

If you ignore that it fit's way better on the fermi lab which is the picture that you sent before, because then even the architecture is correct...

https://upload.wikimedia.org/wikipedia/commons/thumb/3/3f/Fermilab.jpg/1024px-Fermilab.jpg

yes but I’m talking about the terrain not the architecture

No surrounding members use MI-8 helicopters either.

I was wondering this to LHC is much larger, I'm about 30 minutes away from this one.

Maybe that's the disaster, it teleported itself to central Ohio

They got the direction all wrong but the features point to Batavia,IL

The artist writes,

"Detection of mini black holes at the LHC could indicate parallel universes in extra dimensions."

...You idiots! What have you done?!

Alex Nice's ArtStation, Instagram and website.

And thus, the plot of Einstein's Bridge - [wikipedia](https://en.wikipedia.org/wiki/Einstein%27s_Bridge_(novel%29) / goodreads (though that was about the SSC... but still quite relevant to the comment).

Also not far from the plot of Cosm

Nah the only thing the lhc is destroying is the dreams of young scientists.

Yes I am.

Now thats a user name!

Did not realize which sub this was for when I read that headline

CERN giving out NERV vibes.

I remember the irrational panic when it was being built. It’s called a particle accelerator, it shoots particles smaller than a grain of sand into each other.

Mass determines how much gravity it is affected by and how it effects other things, black holes are ultra dense mass usually in the range of multiple suns.

So logically, a bullet has a larger chance to become a blackhole than a particle as small or smaller than smoke.

Primordial black holes are theoretical at best and the field is more focused on quantum mechanics at this point, because the sheer amount of data from the collider is basically unable to be processed in a reasonable amount of time.

That's not quite how it works.

Black holes are also a matter of density, and smashing particles together is a good way of achieving extreme densities. However, our theoretical models also predict the collision energies needed to form black holes in this way are far beyond the capabilities of any particle accelerator. (And if such small black holes were formed anyways, they would instantly vaporize from Hawking radiation)

Most importantly, collisions of particles far more energetic than anything we could hope to muster in a particle accelerator happen naturally in our atmosphere every day, and have been happening for billions of years now.

https://en.wikipedia.org/wiki/Cosmic_ray#Cosmic-ray_flux

Any "accident" the LHC could cause would have happened naturally many times over by now.

Every star in the universe (including our own sun) is also bombarded by those same high energy cosmic rays, and far more of them (simply due to their greater size compared to our planet), so if we're talking about turning the Earth into a black hole, then there should be nothing but black holes in the sky.

Okay, but hear me out; what if we’re in one giant black hole, and all of space is that black hole, and that’s why it’s a vacuum.

Here's a good video by an actual astrophysicist on the issue:

I was mostly joking, but thank you for the link nonetheless.

Space is expanding, though. Black holes don't do that. See here.

My favorite website at the time.

Ok, real talk here though. I wonder if that website will be updated to say "Yep" if it ever does.

If you view the page source (CTRL+U), you will see that it actually as a code that will update the website if it actually destroyed the world. But I think we have a larger problem than the LHC 🐇

Nice, glad to see they actually planned for that! And true, we have far larger, and harder, problems then the LHC.

Certified Ruh-Roh Raggy moment.

please don't be a prophecy

Well, I don’t see any unnamable horrors from beyond our dimension whose very visage would drive humanity beyond the brink of insanity soooo…

"whoopsie doodles"

PoV: They're fucked.

There's already enough irrational paranoia about the LHC. Can we not feed that particular beast maybe?

Eh, ultimately it's just art of an interesting fictional "what if" scenario not too unlike fictional depictions of nuclear power plant disasters, airplane crashes and shipwrecks.

It's posted on "imaginary" technology for a reason.

What's the fun in that? I say post it in a Christian fb group.

Maybe instead to feeding stochastic terrorism from behind a veil of plausible deniability, we should be working to talk them down from their delusions.

I don't see the "fun" in it when scientists end up dead.

Talk them down from their delusions? I would love to know how to do that. Those delusions run pretty deep.

Because you can't extinguish a dumpster fire doesn't mean you should be throwing gas on it.

You get the metaphor. Those groups can be enough of a pain in the ass as is, there's no need to make them worse.

I really hate the way you type. It’s blatantly obvious you’re trying to sound smart but it comes off as really annoying to read. We get it. Sheesh

That's projection. I'm sorry the way I speak and write makes you feel insecure, but that's not my problem.

See you’re doing it again and you don’t even realize it. And that’s not how projection works by the way buddy. If I tell you to fuck off does that mean I’m angry? Or maybe I just think what you said was stupid? I don’t know, which one was it… Bottom line is it’s annoying when people pontificate or even use words like that. Also your reply is extremely psychologically passive aggressive so fuck off you sound like a whiny person who’s annoying in in real life conversations. Let me guess now you’re gonna say you’re like some certified TED talk motivational speaker or some shit. Just shut up with these kind of comments on this site. I’m so tired of people fucking thinking the use of anything other than regular street talk on here makes them sound smart. You know it when you see it when other people post and I know it when I see it when you post and all I’m doing is pointing it out. Have fun be safe on the Fourth of July weekend goodbye

Either I speak this way naturally and "don't even realize it" or it's an affection as you originally asserted, but it can't be both.

Your accusations are mutually exclusive, lmao

Here’s a prime example of what I mean with your speech; are you really laughing your ass off, as you ended your sentence with? No. You’re not. But ask yourself why you felt the need to add that in there. I know why, do you? Anyways, ya sound like a rube who just moved to Manhattan trying to fit in. Good day sir.

That's "miss" to you, lmao

Cool your jets Jenny its just digital art.

Calm down son it's just a drawing

Kinda douchy to call strange women on the internet "son."

Calm down son it's just a SpongeBob reference

Lol, ur so desperate to be an asshole to a complete stranger. That's sad

I literally made a SpongeBob reference and you chose to be offended by it, project elsewhere

No, you called a stranger on the internet "son" in order to be patronizing and now you're desperately hiding behind "it's just a meme/joke" like every other loser whose only recourse is dominance displays.

Again, that's super sad for you

Calm down son, it's LITERALLY just a SpongeBob reference lmao

And yes, the SpongeBob quote is QUITE LITERALLY "calm down son it's just a drawing" if you find that patronizing, work on your sensitivity

I don't know any context in which it is not considered patronizing to address a stranger as "son" lmao

In the context of it being part of a quote from SpongeBob, probably

Still patronizing. Still a desperate attempt to claim "it was just a joke."

Look, child, you're going to find in life that these little things you do in order to feel dominant over strangers in small ways will often backfire. Continuing to engage will only increase your shame.

(lmfao)

You are so OBLIVIOUS LMAO, your sensitivity is only making YOU look more shameful, you are THIS butthurt over a SpongeBob reference. Just think about that

Lol, there's no need to get angry and SHOUT at me. Calm down, kiddo, it's not that bad. You've taken your medicine, now you just have to keep it down.

I agree. I heard the LHC is very nice.

This feels like a foreboding Prediction of things to come

Yeah, maybe. Would require someone taking a dirty bomb there and setting it off though. As nothing at the LHC could cause this.

At this point, I'm hoping for the Blackhole Scenario to happen. Humanity has less and less reasons to survive at this point. Sure it would suck, but either we die to that or drown in trash or ignorance.

Given the size, perhaps Fermincident?

About this Situation there is a movie "Heroes-when your country needs you"

Lookup the Shanghai Superintense Ultrafast Laser Facility

Surprised no one has mentioned Dark yet. It’s pretty much this. Still cool!

Hmm? You commented to the wrong person. I'm the guy that submitted the image.

Uh oh spagehtti-o there goes the fabric of spacetime

Reminds me of the time they did extra math to make sure we weren't accidentally going to cause a chain reaction in the earth's atmosphere with the first atomic bomb.

*Not shown: blue portal in the sky

This looks like it would be an interesting Battlefield 2042 map.

That's not the LHC, it's Fermilab, outside Chicago.

Aw man looks like the hadrons collided :(
