TRANSCRIPT:
Try to imagine somewhere in the universe, a tiny subatomic bubble formed. A bubble inside which all physics as we know it ceases to exist. Particles don’t form into atoms, atoms can’t turn into molecules, all the fundamental forces cease to have any meaning.
And then that bubble expands outward at the speed of light, obliterating everything it touches. Asteroids, comets, planets, stars, whole galaxies just dissipate immediately, their constituent particles flung apart like ashes in the wind. Until eventually the entire universe ceases to exist.
This is a real thing that could happen, spontaneously at any time and at any point in the universe. In fact, it could have already happened, and we’d have no way of knowing it. Because it travels at the speed of light, the first sign we’d get that it happened would be us and everything we know blinking out of existence in a fraction of a second.
This is vacuum decay. And to understand how this could happen, there are three concepts we need to understand.
The first is standard model of particle physics.
I did a whole video on the standard model that I’ll share right here, so I won’t go too in the weeds about this but a quick overview is that all atoms are made up of fundamental particles that fall into 3 categories, leptons, quarks, and bosons.
Leptons are our electrons and neutrinos in their various flavors, quarks make up protons and neutrons, and bosons are force carrier particles, they make the four fundamental forces possible.
But the final piece of the standard model that we know of so far anyway was the famed Higgs boson.
But the Higgs boson is actually just a tiny chunk of the Higgs Field. Which brings us to the second concept we need to understand… Quantum field theory.
So I’ve never really done a video on Quantum field theory, so that’s long overdue, but basic gist of it is that all of the particles I just mentioned are actually just excitations in a corresponding field.
In other words, reality as we know it is made up of layers of fields of different energy levels. You’ve got quark fields, electron fields, neutrino fields, boson fields, and most important for this discussion, the Higgs field.
When the Higgs field was predicted, by the illustrious Peter Higgs, it was calculated at a very specific energy level. Any higher or lower and physics as we know it cease to exist.
126 GeV is a tiny amount of energy to us, but as particles and fields go, it’s pretty high. Scientists began to wonder if this was really as low as it could go.
And with a little fancy math, scientists at CERN in 2013 were able to prove that there is, theoretically, a lower energy level that the Higgs field could exist in. An ultra-dense Higgs field.
This means that the Higgs field that keeps the entire universe together is not a stable true vacuum, it’s a metastable false vacuum.
Which means that if at any place in the universe a tiny part of the Higgs field slipped down into this energy level, entropy would take over and the entire Higgs field would collapse into the ultra dense state. - Zábava
The way I see it, if it were true, it would be
A) quick and painless (we would literally disintegrate before our nervous systems could process what was happening)
B) impossible to plan for or avoid.
If there was a quantum bubble rushing towards us as right now, I see no reason to dedicate mental energy towards worrying about it.
An interstellar civilization with FTL travel could probably detect and plan for one. Wait until a probe or satellite in deep space suddenly stops sending a signal, and send a new probe a light-year away from where the first vanished. If your new probe vanishes a year after the first one did, there's probably a quantum vacuum bubble expanding at the speed of light towards it. At this point you pack up your entire civilization onto FTL ships and run the hell away, until you reach a galaxy that, thanks to the acceleration of the expansion of the universe, will move away from the field faster than the field can expand.
Of course faster than light travel is even more improbable than a vacuum field collapse itself.
Joseph Henderson Just hide under your blanket
I agree. I can't stop it in any way, so bother worrying
Plus nobody would be left having to mourn the loss of anyone. And no FOMO.

The universe is expanding faster than light, so eventually this theoretical vacuum decay bubble would not be able to expand faster than everything around it. Sleep tight my friends.
I know but that also means we have a limited time to explore the universe.
It depends. Is it an absolute bubble expansion, or a relative one...IOW, does a vacuum decay bubble expand/propagate through spacetime as if it were massless (uncoupled from the fabric of spacetime, meaning lightspeed is the absolute limit), or does it propagate as if it were massive (like matter, being dragged along with spacetime expansion, going faster and faster. That is the big question.
What if the expansion triggers more and more of these bubbles to appear throughout the universe? Only because the field expands as wel and has more "surface" to increase the chances?
Until the expansion slows down at some point and then shrinks and the two catch up
And if it happens near milky way?
Can’t I just Mandela Effect my way into a Universe where all the same laws of physics exist, but the Higgs Boson particle is in an actually stable position? Please?
Well, if the multiverse theory is true, the answer is "yes" due to the infinite nature of the multiverses. In fact, there would already be multiverses that have already experienced death and multiverses where death is coming. We could be in a multiverse where it never happens, or we could be one where it does. I suspect that every day we travel between many multiverses that are ever so slightly different and this explains the "Mandela Effect". Eventually, with all this moving, someone is going to notice things aren't the way they're supposed to be. In the past, this was not a problem as people didn't communicate as easily. Today, it's trivially easy to communicate and share thoughts, ideas, and experiences.
@@NotSoCrazyNinja knowing my luck i’d end up in the one where vacuum decay has already happened
@@obsidianworkbench8009 I think there is a limit based on belief. If you believe, genuinely, that something can happen, you are more likely to find yourself in a multiverse where it happens.

I used to be scared of all types of cosmological events when I was young. Went to sleep at night telling myself it was unlikely an asteroid would smash int earth or that it’ll be billions of years until the sun becomes a white dwarf. Glad to see I’m not alone in that front! Keep up the amazing and informative videos!
I thought our sun was NOT going to explode... it will expand to a red giant, then shrink to a dwarf... no nova...
SuperVstech Expanding to a red giant is like a very slow explosion though, in a way. We'd still get cooked but not instantly or without warning. I think the cool thing is that the icy moons of Jupiter and maybe Saturn would end up in the habitable zone. The slowness of the process would mean they could be nice places to live or visit for thousands of years before freezing again.
Yep. Our sun isn't big enough to go supernova. Red giant which will consume the inner planets...then white dwarf
Mind you, in a billion years the sun will be hot enough to boil off all water on Earth, so unless we go off into space by then it doesn't really matter.
The sun needs to be tamed. In time, it will be.
bez750 Actually I think there was still an open question of whether the Earth would be enveloped by the red giant Sun. The reason is because as the Sun expands into a red giant it loses mass and thus the planetary orbits would similarly expand outward due to the lessened gravitation pull. The last time I read about this the calculations were close, apparently the Earth is right on the edge of where its orbit might expand outward just about fast enough to avoid being “eaten” by the red giant.
Not that matters much for life on Earth. The temperature increase will boil off everything on the surface long before Earth is ever possibly devoured. Still, it’s an interesting physical dynamic to think about. :)

There are a lot of videos on CZcams explaining this but this is by FAR the best
I understood more about physics by watching this video than from my 5 years in college.
I wouldn't put this on a resume though.
LOL Not like it would help a systems developer like myself. If I had a quantum physics subject in highschool then I would have been in a very different field. Schools (at least those that I graduated from) don't even talk about the standard model at all. It feels as though this is where stuff really gets interesting.
He doesn't even cover any useful formulas for application... so you got seriously ripped in college.
And like the narrator said, I certainly wouldn't say that in an interview nor put it on a resume.
Formulas can be searched. What bothers me though is that even in highschool they never even introduce the concept. As for being ripped in college, well, I never really thought that since I was lucky enough to study in the Philippines rather than in the US. I never had any BS course, and the curriculum pretty much covered everything that I need to know about information systems.
Almost everything he said is wrong though :\
Joe - I hope you make really good money off your videos, I sincerely think you are the best on CZcams for combining clarity, humor and accuracy and some really interesting scientific topics. Nice work!
most of your space videos are anxiety inducing and fascinating at the same time, i hate it and love it at the same time.

"That's how it got the name 'The God Particle."
No, no it isn't lol.
I know right? I thought it was shortened to "The god particle" from "The goddamn particle" because it was so goddamn hard to find.
I really dislike the name 'god particle.' Just call it the Higgs Boson. The 'god particle' was given to the Higgs for sensationalist reporting in popsci articles.

we are , this place is similar to where we used to live but just a little shitter.

The odds here are different too, on everything from the lottery to sports. I mean drastically different. 5 dollar scratch offs should have a hit rate of around 1 in 3, it's more like one in 8 or 9 here . also the law enforcement here is very different about what they will and will not tolerate. many people I have know have abruptly changed their personalities literally overnight, a complete 180, in some cases phobias they had their whole lives are gone . also have you noticed that everything here malfunctions constantly? I mean everything , weed eaters won't run right , lawnmowers barely start , jack handles break, sockets, wrenches, all electronics , game systems, phones, nothing lasts for much longer than a year, tires, most people will remember maybe having a flat once every 5 years or so. now ,here it's more like 4 times a year. the odds are stacked. something is very off, also seems like only about half the people are here from what I remeber. when I go to the store the parking lots are half full, I remember them always being at least 3/4 full and having to park and walk to the entrance , stadiums and concerts are the same,
I'm already living in the upside down. In Australia. Even though we don't actually exist.

I am feeling a strange urge to destroy the Universe
i feel like this is one of those topics that is so out there and abstract that unless you are somebody who has a really good understanding of all these concepts, you cant even even begin to accurately conjecture about the effects such an event would have. I will whole admit that while space time stuff fascinates me, there is a lot of stuff like this that ends up going over my head in various ways due to the complexity of the questions being asked.
I just willingly watched something I knew would make my paranoia levels jump 10 levels up and it did.

NO MORE DEBT WEEE. The “Goddamn” particle is the more accurate way of describing it, citing the original theoretical scientist
When you said the line about being more concerned with the sun exploding as a kid than other "normal" scary stuff. I felt that. I watched a video about the suns death when I was 8 and it freaked me out big time lol

I've been watching alot of your videos on quantum mechanics, and now this. I'm having an existencial crisis!
maybe it was in a higher energy state and we're what happens after vacuum decay
It almost certainly was in a higher energy state a small fraction of a second after the Big Bang, so to an extent, you are right. We are (fairly) sure we can more or less the progress of the universe after the first 300k years or so (the point at which it had cooled down enough for light to start being a thing), and we can "see" that it hasn't happened yet... unless it has, and the wavefront is approaching at c, in which case we'll never know. Have a nice day :)
No, in the video he mentions how it was found out that the Higgs field *could* exist at a lower energy state than it is now, meaning we're not at the lowest it can be so it could still happen now even if it happened before.
I bet my burritos you think the glass is half full.
How could anybody "unlike" this? Seriously, c'mon you trolls! Another great video, Joe.
Kevin Kevech every dissenting voice is not a troll. None of this is physics, its nonsense, assumptions, and critical misunderstanding of what drives the universe.
It is called cuantum physics kido
Because Joe Scott is an idiot and should stop talking about physics, a subject he clearly doesn't understand?
Not everyone knows that the unlike button is meant as a "I disagree" button, not a "that's scary and I don't like feeling scared" button.
I seriously hope that's not the case, because that means even _fewer_ people than I thought can see past Joe's idiocy.
Watching this in mid-March 2020 to feel better
Great video!
Technically, the sun isn't large enough to explode. It will likely become a white dwarf after expanding into a supergiant. It will from there diminish in energy until it dies out.
So says you 😒
Correct. And ironically, in this video about cutting edge and futuristic physics theory, this 50 year old *fact* is the only thing Joe got wrong. (At least that I noticed.)
It's more than just NASA and Zeitgeist saying that. Other government scientists, independent scientists and the greater scientific community agree that the sun is too small to "explode" and will most likely do as Zeitgeist stated. If you doubt them then learn some physics, math and the theories behind how stars work and crunch the numbers yourself and you will most likely come to the same conclusion
@@StratBlackFishRa Thanks man! Physics is awesome!
I read that it would expand first and that expansion would envelope the earth and destroy all the things that keep us alive. Ozone, atmosphere and then of course we'd be inside the sun and obviously dead
WOW, this was my nightmare as a kid too! I saw a documentary about the sun's death, how it will swell up to swallaw earth before burning up, and it scared me shitless and left a lasting impression in me. But I've never heard of anyone else having this childhood fear before, so it was kinda funny to hear almost my own exacty childhood reasoning from somebody else.

The higgs boson is not what gives particles mass. That's what the higgs field is doing. The fact that the higgs boson exists is just a side effect of the higgs field
mathyoooo2 Exactly!
Yes, and the energy of the virtual gluons contains mass due to their interactions with the Higgs field through the Higgs mechanism.
No, because gluons do not interact with the higgs field. They are massless. The mass via the virtual gluons comes from the famous E=mc^2.
The "higgs boson" happens to be how physicists call the higgs field. Every particle is a field, so distinguishing is a little redundant.
"Actually, most mass comes from the energy of virtual gluons."
Nope, nothing virtual about them. "Virtual" is a word that refers to internal factors in perturbative calculations. The effect that gives around 99% of the mass on your body, chiral symmetry breaking, is nonperturbative, so there are no "virtual" particles associated with it.
The easy way to think about it is: the Higgs gives mass to _elementary_ particles, with the possible exception of the neutrino, which we don't understand. Protons and neutrons are not elementary particles though, and get their mass from somewhere else.

Wow, Joe. What a fun guy you are.
Had a quick scroll and couldn't see anyone else mentioning this - The Higgs field doesn't assign mass to everything else, it only allows for the previously unexplained mass of the weak force charge carriers (W and Z bosons). It was a tweak made to the standard model to make it conform to observations it didn't predict (namely the massive nature of the aforementioned W and Z bosons).

The first civilization that can develop quantum tunneling tech and tunnel a Higgs-Boson to this lower density state, wins.
only if they're suicidal
otherwise it would be a draw
Would you like to play a game, Dr Falken?
The only way to win is not to play the game.
They would likely only destroy their own local group of galaxies and maybe the next few over, as even if we had ships going the speed of light right now headed out of our local group we would never escape it before the universe was expanding to fast ever get to galaxies out side of it. And since vacuum decay works at that same speed, neither will it.
Total annihilation is a 'win'?
2:03 - Best SONG Ever!
Nicely done Really like the no beard look.
Some nuclear physicists thought that detonating the first nuclear bomb would cause an infinite chain reaction that would destroy every single atom on Earth. They were wrong, obviously. Some quantum physicists thought that activating the large hadron collider could create a black hole that, instead of dissipating instantly, would destroy every single atom on Earth. They were wrong, obviously. There are countless other examples like this, point being: don't buy into "infinite destruction" theories. The people who propose them often suffer from paranoia and like to pretend that entropy doesn't exist, despite it being an everyday-and every microsecond-aspect of their lives.
a lot of those doomsday scenarios were also sensationalize to bring in readers or viewers. i cant speak so much so for the atom bomb, but with the LHC there were a large number of scientist that stated that there is a risk of some catastrophe but it was so incredibly small ( something like you have a better chance of winning the power ball lottery 37 times in a row) that there was no point in worrying about it.
The LHC thing was always a fad and typical example of "chines whispers" style miscommuication. Indeed some physics theorized that the creation of micro black holes were possible. "Scientific" journalists took on that and said, LHC could create a black hole that would swallow us all!!!!! What those scientists knew at the same time and the journalists didn't get... first thing, cosmic radiation is actually stronger than the LHC, so if it would be possible, it would have happened long ago. (BTW: why you still need an accelerator is, cosmic radiation won't hit enough just right in your detector). And secondly why they still considered micro black holes possible is that they would be extremely short lived. Since hawking radiation would dissipate them immediately. (Again, knowing that if it would be possible, it would occasionally already happen since millions of years in earth atmosphere)
@@rson17 exactly, very sensationalized, and for doomsday devotees, fairly fringe in terms of the physicist community as a whole
For nukes, we didn't have the science to know it wouldn't, and the question wasn't so easy to answer as any undergraduate heat transfer equation due to the enormous pressures involved. LHC was quite different, we knew that was pretty much a joke.
This is in another class entirely. The likelihood of it being so infinitesimal means it's not exactly something that would have happened somewhere else in the universe, even. Where we know black holes exist (kind of) and know how quickly they should decay making that danger laughable, where we've tested thermonuclear weapons and found they don't cause any kind of run-away fusion (phew), this is something that, as far as we understand quantum physics, is possible. Does it make sense to worry about it? Not really, though maybe some day we'll have the technology to build some kind of island against it. But we really can't say it's pure paranoia-fueled bologna.
