I would've thought the universe would use vacuum on a Planck scale so there's no chance for microscopic bubble nucleation to exceed a critical size.

Vacuum decay is a hypothetical thing that hypothetically happen in our universe, or in other hypothetical universes, that is very destructive. The idea is old but the relevant modern idea comes from Quantum Field Theory and the work of Sidney Coleman. In the picture posited by Coleman, it is possible (or even likely) that the universe we see that is basically a slightly excited state of the possible states of quantum field theory, but that what we think of as a state with no particles or energy (the vacuum state) might not actually be the lowest energy state, and some sort of decay from our “false vacuum” may occur. Coleman posited that the process would start as a nucleation process; it would happen at one point and expand like a bubble. The calculations indicate that once the bubble was formed, its radial rate of expansion would quickly approach the speed of light, meaning that this exploding bubble would likely engulf anyone before they even got the chance to see it coming.

Coleman’s calculations are still widely accepted today, except he made some predictions that were not supported in subsequent tests. He predicted that coherent beams of pions would “roll over” the vacuum state, but I am pretty sure people made such beams and nothing actually happened.

So realistically I don’t think there is any real risk of vacuum decay; even if it were possible I think it more likely it comes as a giant shockwave out of space and we all die instantly; aside from that possibility I think we are totally safe

The idea is this: The vacuum of empty space isn't empty, it's full of quantum fields and since they are quantum they have non-zero minimum energies. The one usually mentioned when it comes to the idea of vacuum decay is the Higgs Field since it fits the requirements best. So the field has a minimum energy, but for whatever reason it's might not be the real minimum. At least one lower energy state exists. So at any time due to the rules of quantum mechanics, even if it's extremely unlikely, the field at some point anywhere in the universe could jump to that lower state releasing a whole bunch of energy in the process and fundamental changing the laws of physics at that point. If / when that happens however that change would then propagate at the speed of light to the rest of the universe. So at any moment we could all die, our atoms ripped apart, and we'd never know it was coming.

I don't think there's any build up with black holes creating a central movement with itself.

It's yet another para-religious apocalyptic surrogate narrative to discourage people from trying to extract useful work from the vacuum, like the one about the risk of atmosphere igniting due to atomic bombs, the planet being devoured by a black hole due to CERN and other inane shit like that.

>>17077300
why worry about something you can't see coming? who cares

>>17077300
You should really stop worrying about popsci slop

>>17078162
And how are we supposed to extract work out of the vacauum?

>>17078198
not with that attitude

no refunds, retard

it would need to be within 100 lightyears to effect us in our lifetimes the odds of that are basically zero

Shit that cant happen

>>17078854
but it might happen any second

>>17080151
anything could happen to be fair

its the quantum physics version of worrying about the sun exploding and destroying earth in 1 billion years

I know what you're doing. Stop it.

When you die, you’ll practice making small planets and solar systems with your mind. And then you’ll go find some humans on earth or some other earth like planet (or whatever life form you want), abduct and hypnotize them against their will, and use their sperm and eggs to seed this planet from a UFO. Then who knows, you might become God.

Theoretical physicists from Syracuse University and the University of Portsmouth published a study in the Journal of Cosmology and Astroparticle Physics. Their findings introduce a new reason why our universe is likely much safer than previously feared.

The "Cosmic Lockdown" Discovery

The newly proposed mechanism explains how the early universe essentially protected itself from instant destruction during its period of rapid, hyper-inflation right after the Big Bang.
• Environmental Decoherence: The researchers mapped how quantum fields behave during rapid cosmic expansion. They discovered that a quantum field's ability to undergo dangerous tunneling is heavily curbed by decoherence—a process where a quantum system interacts with its wider environment and starts behaving more like a predictable, stable classical system.
• The Quantum Zeno Effect: Because the surrounding environment effectively "monitors" the quantum state through continuous interaction, it creates a phenomenon similar to the quantum Zeno effect. In simple terms: a monitored quantum system struggles to transition or change states.
• The Result: This environmental interaction acted as a cosmic lock, freezing the Higgs field safely inside its localized energy minimum (the "false vacuum") and drastically reducing the chances that it could ever tunnel out into an apocalyptic true vacuum bubble.
While this model is a simplified iteration that doesn't yet account for all variables like fluctuating expansion rates or full gravity, it provides a powerful mathematical framework suggesting the universe possesses a built-in safety switch.
Would you like to keep an eye on this developing physics topic? I can set up a task to monitor for any future peer-reviewed updates or experimental confirmations regarding vacuum stability.

so everythings gonna end or what?

this still scare me btw

Nothing ever happens anons. The physicists who believe in this type of stuff are “theorists “ whose business it is to come up with speculative guesses on what might happen.

The people who actually are engaged with the physics of particles do not actually trust those guys, we realize they need to make a living but the safe bet is on that current particle physics works how it has been working for 20 or 30+ years so there is no panic to take the theorist bullshit seriously

Welp this guy says it's unlikely to happen any time soon but he did seem nervous. In fact with my infinite paranoia I tried checking if his blinks are morse code, but I can't find consistant timing anyway.
