- Every fundamental particle has an antiparticle: there are antiquarks, antineutrinos, antimuons, antitauons, and of course antielectrons - though we call them positrons.

I'm sure the anti-people in the anti-universe are asking the same anti-questions. :D
+netchingretch and writing the same anti-comment
and making an anti-reply to the same anti-comment
The thing is that the anti people in the anti universe thinks that they are original and we are the anti so yeah...
we are probably the anti particle to them
+allan chartrand yup lol
+allan chartrand yeah
If the universe were mostly antimatter, we would call it matter.
and matter antimatter
The comment was "if the universe was mostly made out of matter" and so on, so it wouldn't be rare
But in the end does it really matter what we call what?
Just like how there's nothing really that makes the positive numbers "positive" except that we've used them as the default and called them positive. However, the main question is why is there an inequality between the energy values of these excitations (more of one than the other).
That's not the question, the question is why aren't there equal amounts of matter and antimatter in the universe
matter is anti-anti-matter
wow
totally.✌
+Bayonetta Is My Goddess I know 🤘
So does that mean antimatter is anti-anti-antimatter
That surely means matter is anti-anti-anti-anti-matter.
Shortly:
It's like 2+(-2)=0 but with explosion.
doesn't make sence right
You summarized the summary
Yeah
What a genius ...
The explosion is the 0

But to physicists, the answer matters.
Love that one.
nice :0
So for every flat earther, there is a anti flatearther?
Yes I guess xdd that's true tho
Imagine how scary it would be the other way around!
Yeah, but for some reason the universe created more anti flat earthers. Strange.
We call them sane people
Umm... no there are many more anti-flat-earthers. It's called the great flat-earthers deficit and no one knows what caused it...
Hitting 0 and getting 2 and -2.
I love that analogy
Isn't it just an assumption that we say the universe created more matter than anti-matter??? We cannot see the whole universe, couldn't the antimatter just be in some other place?
It could but then you'd have to explain how the two got so neatly separated that you don't even see regions where the matter and antimatter parts of the universe violently meet each other.
Penny Lane wouldn't the part that meet each other just be an empty void after the first few collisions?
Well, when you "zoom out" far enough to look at the universe there is a conformity, it all starts to look the same wherever you look. That implies the parts outside the observable universe are basically the same as the observable universe. And there is no other place since the place is the universe... Sure there could be pockets of anti-matter but with all of the movement there has been since the beginning of the universe it's unlikely they have not come into contact with any matter at all.
Peter Wraae Marino Remember that we can look way back in time, basically to the beginning of the universe. If there ever was a period of violent collisions of matter and antimatter parts of the universe that then stopped for some reason, we'd still be able to see that.
Penny Lane As I understand it there is a limit to how far we can look back since everything is accelerating away there comes a point when the light will never reach us.
i bet they make these whole videos just for the joke at the end
Something has a sick sense of humor !

The idea that particles can be generated out of empty space is magical to me!
Physics is awesome ✨
they are simplifying it
It’s not really empty space, it’s gluon energy fields, you can remove a part of the energy field creating mass.
I really enjoyed your analogy of 'hitting 0 with a hammer and getting 2, and -2.' Getting lots from nothing is quite a hard concept to properly understand, but this made it click for me! Thanks for your beautiful videos :)
Wait... what about Black Lives matter?
Good one

Black Holes Matter
Please don't destroy my favorite subject, physics, by making a pun about terrorists.
Physicist: "Everything is matter."
Me, an intellectual: "Nothing else matters!"
Musician: "it doesn't really matter... to me!"
One theory I've heard is that these particles and anti-particles would appear randomly in space (that part has been proven, I believe). If this happened right next to a black hole, and there was an slightly larger chance for one to escape than the other, and it was done right on the edge of it's effect, then one would be sucked in while the other, not. If matter is sucked in even lower than 1% of the time, a buildup of this could "create" a lot of matter, given enough time.

I've never liked physics at school. We would always learn the formulas and then copy them in the tests. No thinking, no questioning. It was a neutral field. A subject that honestly back then barely mattered. But one day a friend of mine showed me a channel which opened up the world of physics to me. This channel was none other than minutephysics. You guys have inspired me to think about the universe. To question and ponder. What you guys are doing is really awesome and I just want to thank you for it. You guys are really making physics and matter actually matter. So thanks and I will keep watching your videos. :)

WHY SO MUCH MATTER PUNS D:

Because people just can not not not not not resisted the urge to release there energy in the form of puns.

Don't give up. You _matter._
Anti-matters: :(((
You had me fooled sir
how do you know taht there are more matter than antimatter? maybe, somewhere really far away, there is a part of the universe made out of only antimatter
Then it would have collided with the matter aoiund us, you have to remember that even it is far away it will still very quickly find matter and collide with each other
Agent1523-Minecraft Maybe... the antimatter is surronded by vacuum, so it doesn't found matter because of the sapce between them... idk, just thinking about things that I don't understand... =P
+João Vítor Costa In the early universe, things were much closer together so that region could not avoid annihilating with the surrounding matter. It would've left a very distinct imprint in the cosmic microwave background radiation, which we haven't seen.
It is said that there was as much antimatter as matter in the universe, which makes sense that at some point there are planets, stars or galaxies made of antimatter
Paul Leonard that would be awesome!! an antiplanet!! yeah, Im totally going to study physics when I grow up (I'm 15)
How did they find out about anti-matter? When i was in school they told us the Big Bang theory and it was basically there was nothing then there was a thing (because science) then it expanded (also because science). I mean is there solid evidence or is this a theory?
The stuff has been created in labs
Evidence. Watch a few other of the videos on this channel.
The Big Bang is a theory. But a better theory than saying a god made everything.. My question to that is always - who made the god?
***** EUH NO, its radioactive
MrYogiz Gaming Yes, it's a theory, but it has been proven to be true.

I love minute physics because it makes me feel smart
Yes, once you should try this👇
th-cam.com/video/ofj4K2TtNcY/w-d-xo.html
And many interesting short videos
You aren't smart.
Personally, the physicists are pissing me off in the matter-antimatter philosophical debate. Essentially they are asking themselves why are we made of matter rather than antimatter... so what? If it were the other way around, we would be asking ourselves the opposite of the question we do now.
Now how the fuck does this constitute a proper scientific research? A chicken and the egg bullshit...
but have more matter than antimatter OR more antimatter than matter would both be equally perplexing. because as far as we know there should have been an equal amount of both. that's like say that asking why human are conscious is a stupid question because we wouldn't be asking if we weren't conscience. it doesn't answer the question.
euducationator This is another thesis that is more philosophical than scientific. If you accept the multiple universes theory then the answer is as follows:
There are infinite universes in infinite combinations. One of the basic laws of physics is that if you let stuff such big bangs repeat themselves for long enough, tiny changes will begin to occur, eventually leading to alternating results to creation algorithms.
Also, consider the fact that if you alter the laws that govern "this" universe just by a fraction, all the life generating conditions no longer become possible.
So the questions "why this universe" and "why only matter" really are irrelevant, because the answer is because we couldn't survive "anywhere" else.
BigBadBeef
The multiverse theory "may" explain the discrepancy, but that does not mean that it is the only answer, or indeed, the correct answer. Looking into other reasons as to why one type of matter dominates the universe is very important thing to do, as it opens up the possibility of expanding what we know about particle physics.
No that is not the question being asked - you are right that that question would not be something we could answer scientifically - what is matter and what is anti-matter is simply a convention.
The puzzling question is why is the universe made out of predominantly matter (one of the two) when in every process we know matter and anti-matter is produced in pairs, meaning you can never create more anti-matter than matter.
You misunderstand us. There is no difference between antimatter and matter in that sense, as we could have named it the other way around. The question is why there are not equal amounts of both kinds of matter in the universe. It is that imbalance and the mechanism behind it which we seek to understand.
So is there a way to have a negative neutrons?
Oh wait, no, that's stupid.
Bobert Johnson Hmmmm, neutrons are made of 2 down quarks and an up quark, so an ant-neutron would be 2 anti down quarks and a anti up quark :3 lol
Bobert Johnson In Soviet Russia, negative neutrons ask if there is a way to have YOU!
Bobert Johnson neutrons have neutral charge *in total*, but it's made out of quarks that have charge, and not symmetrically -- two down-quarks (-1/3 each) cancel out the charge of a single up-quark (+2/3) to make a neutron. An anti-neutron would be made out of two anti-down-quarks plus a single anti-up-quark.
Ditocoaf I think you need a girlfriend, lol.
Anti neutrons exist
"the answer matters"
*sr pelo laugh*
An antimatter bomb is an ideal weapon. Its far more efficient than a nuclear bomb, its not radioactive so its undetectable, 1kg of antimatter would create several orders of magnitude more energy than the czar bomb, and best/worst of all it doesnt create a radioactive waste land. You could literally destroy a country and rebuild the next day. This explains a lot about why china is creating the worlds largest particle accelerator/collider, which is required to create antimatter. In the future it might be known as the Beijing project(in reference to the Manhattan project).
The typical problem is : how do you store 1kg of antimatter? 1kg is huge even to store in a gigantic container with magnets, so in a bomb?
Pierre Vandermaesen You would have to store it in a vacuum and control it with an induced and controllable magnetic field. The problem is that most elements are not affected by magnetism, however If you have 1kg of an ion of antimatter you could potentially use a magnetic field to manipulate it and keep it center. Even more, since you can have antimatter for any element you could potentially create a magnetic antimatter which could be manipulated with a magnetic field even easier than an ion. Of course all this would have to be done in a near perfect vacuum with a high risk of an uncontrolled detonation.
What idiot told you a matter-antimatter reaction is not radioactive? It gives off a motherfuckton (I believe is the technical term) of photons in the gamma part of the EM spectrum.
AlbertaGeek
The question is, will it be "just" a burst of radioactivity.
Or will there be radioactive fallout?
AlbertaGeek I didn't say it wouldn't emit radiation. It will probably emit a whole lot of gamma rays, but it will not leave the area radioactive.

***** And probably provide enough energy to blow up what remains of you, as well as your surroundings. Actually, the antifat would only be able to annihilate an amount of matter with an equivalent mass, meaning that only the mass of your fat would be annihilated. It would still blow up.

Great channel.
Annihilation teaches us one thing: matter and antimatter is made out of smaller stuff. But what is 'energy', what are 'waves' of radiation. What is that stuff made of? Will it always be limited to equational descriptions or will technology ever find out? Even more peculiar is the 'quantum field' and also the 'Higgs field'. Excitations in a field is rather vague, but granted it's the best we got today. You can take it even further then: what is the field made of, what generates it? Physicists want to learn the truth of all things, they will keep looking
Mindboggling though that everything is just forcefields. Row row row your boat gently down the stream, merily merily merily, life is but a dream...
A video from Veritasium mentioned that the big bang, or expansion of the universe from super dense "stuff" may not have been Mt. Everest in size before expanding. It may have been infinite in size. The visible universe we see is merely a Mt. Everest sized portion of that super dense "stuff".
Therefore, matter/antimatter can still be equal in it's generation if it follows a probabilistic nature. Our visible universe is simply within a tiny patch of the universe that happens to be majority matter.
The big bang was fantastically uniform, where one patch of space was virtually indistinguishable from any other. Following that, the rest of the universe would've looked extremely similar to our observable one - mostly matter. Though not mentioned in the video because they're uncertain, we do have theories that suggest the difference in quantities might be down to the differences between matter and anti-matter, so that would apply everywhere.
If the universe is infinite, then statistically speaking, there are anti-matter galaxies out there that defied the odds, but they're unimaginably rare.
If that were true, the amount of matter in the universe would be proportional to the square root of the amount we started with. In other words, for every particle of matter, there'd be a universe-worth of energy. Furthermore, the probability decreases superexponentially as the matter to antimatter ratio increases. It would be many, many orders of magnitude more likely for your brain to randomly appear in a section of the universe with equal amounts of matter and antimatter than it would be for this universe to actually form.
And it's not even clear why it would be probabilistic in nature. There might be some uneven distribution from it moving around, but normally it seems that matter and antimatter must be created in exactly equal amounts.
Everything outside the cosmological horizon does not exist as seen from here until its effects arrive.
Zazz30 The universe at the time was extremely uniform, and it likely still is. But do you know how big the universe is? For all we know there is not a single speck of antimatter in the observable universe, and it still wouldn't be a trillionth of a percent non-uniform.
Behind TheWall We know there's some antimatter. For example, this cloud of positrons: www.nasa.gov/centers/goddard/news/topstory/2007/antimatter_binary.html
What about Dark Matter?
we still dont mnow much about it but surely its made of normal matter(or it would annihilate with our universe)
the only thing i know about dark matter is that we can't observe it and we only know of its existence because of its effect on gravity
Dodgyboy43
1) because it has a gravitational field it has mass
2) we know it has a gravitational field because it bends light
3) we can map the locations of this stuff measuring the distortions of light from different angles.
3a) it happens to surround entire galaxies (from the map i saw)
4) we think that it is a WIMP (weekly interactive particle) and dont interact with regular matter or extremely less likely to.
5) a new idea suggested that the "Higgs boson" is a Dark matter particle made up of new fundamental particles called the "Technicolor quarks", but this is just a hypothesis.
thats what i know on the subject of dark matter.
Thanks guys for the info.
Random (but according to Vsauce not random) but a BIONICLE based on dark and anti matter would be "the bomb." Also, thanks for the insights Arceus :)
Btw, matter and antimatter are not EXACTLY the same, in the sense that the weak force behaves differently on the two.
How do we know that we aren't made out of antimatter and normal matter is what we call antimatter? If they are the same but with only the difference being their charge is the opposite, then we only see ours as being normal because we are made of it. It's all a matter of perspective. So why did more normal matter than anti-matter stay around? It didn't.
Well the point isn't "we are made out of matter", the point is we're are made of something the humans called "matter", and then, they found the opposite of this thing, so they just called it "antimatter". Just like volcanos, if we were living under the sea, we would call the underwater volcanos "volcanos" and the volcanos "aerial volcanos"
It is just a matter of perspective. The whole nomenclature is just a convention. There are 2 types of matter, what you call them is irrelevant. We're made of one kind, which we happened to call 'regular' matter because it was the first we found out about. Then we discovered the other kind of matter with identical properties but opposite charge, so naturally we called it 'anti'-matter, but the names don't mean anything, they're just a way for us to distinguish between the kind of matter we're accustomed to and this other type of matter that is different.
Yes, so the real question is how can there be more of one kind if we started from nothing?
SmokeySmudgeStudio That is indeed a good question which, as far as I'm aware, has not been conclusively answered yet. From what we know of matter and antimatter, equal amounts of both were originally created (unless we got some of the math really wrong) but for some unknown reason we can find almost nothing but regular matter, and nearly no antimatter.
it's a "matter" of perspective :DDDDDDDDD

Maybe the big bang had two sides. When a photon split sometimes the matter would come to our side and the anti matter on the other and this other universe is perfectly identical to us just in the opposite charge. Figuratively we wouldn't be able to tel the different if we went there since they have the same properties (well except for the fact that we would blow up as soon as our particles canceled each other out)
Jordan Harb it had zero sides since at that time the universe was a singularity and therefore 0 dimensional. then it became three dimensional and was literally everywhere, a bit more than 2 sides
But what about other dimensions outside our three-dimensional experience? 4th-, 5th-, or 6th-dimensional symmetry??
Jordan Harb if you are right then people in that univers must be the oposite of us....i mean if we born grow up an die they may "undie" grow young and "unborn" or if we walk straight they may walk backward or if our time is positive theirs may be negative.....hope you understood what I meant...sorry for the bad explaining
Look above at my comment! We had essentially the same hypothesis!
@@thanasgoga7127 No, that's nonsense. The rules are the same. Only the matter changes.
Electrons are negative
Protons are positive
Electrons and protons are opposites
Positron: allow me to introduce my self
i swear this 3 minute is the best ever on earth 3 min explanation ever
MinutePhysics
I want to know more about Positronium.
it has 1 neutron, 1 electron, 1 positron and 0 protons, correct?
does it qualify to even be an atom with no protons?
if it is an atom, where on the periodic table of elements does it fit?
if its not an atom, what is it classified as?
if its not an atom, and it has a new classification, would there be an equivalent to the "periodic table of elements" (where the core is Neutrons + e+)
can other "higher" [insert classification here] exist? such as (2e- + 2e+) ECT.
why are they so unstable?
Hypothetically if they can be stabilized, is there any assumed properties, interactions?
is it possible to happen in nature?
Can other Particles form a "atom" like this?
No protons and neutrons, just a positron and electron. It's like 1s^2 electron shell without a core, where one electron is substituted by a positron. Those two swirl around for a very small fraction of a second, and then annihilate due to instability caused by electromagnetic attraction (instead of repulsion in a normal 1s^2 shell).
Slithereenn
heh interesting. they orbit the center of mass then?
Ziliath Well, since you can't really say that electrons and positrons are located in well-defined points of space like planets, they don't exactly "orbit". It's really quirky stuff. But if you'll simplify things to a level of the 4th grade, you'll get something like orbiting common center of mass, yes.
So does that mean that there could be anti-dark matter?
Sooo matter?
TheeeTwan No, anti-dark matter.
answer gonna come to this interesting question when we'll know more about dark-matter..
Should it be called antidarkmatter or darkantimatter (if those spellings are weird, check the title of this video).
Light is anti dark matter.
That was such a good explanation.... i get goosebumps thinking scientists figured out how to even get anti matter 😵
Okay.
Okay.
Well, if the only way we know about the existence of other galaxies is through the light they give off, would we be able to tell if they are anti galaxies? I mean, if light has no charge wouldn't it behave the same way with matter and antimatter?
That's true. There could be large deposits of antimatter in our universe, maybe even enough to make stars or galaxies.
but wouldn't the intergalactic gas destroy those galaxies?
XeXWill Actually we know that is not the case, at least not in the observable universe.
The universe is completely filled with neutrinos. Trillion are zipping through you every second. Antimatter stars or galaxies would constantly be annihilating massive amounts of neutrinos and other particles causing very bright light sources in the wavelengths that carry that exact amount of energy. We would easily be able to detect that in the spectra of those stars and galaxies. Mind you that we classify stars pretty much solely based on their spectrum.
It's possible, but we just don't observe it while we definitely should be able to. That makes it pretty unlikely.
Niosus Ah okay that makes sense. Wouldnt the neutrinos just pass straight through the stars, instead of annihilating though?
XeXWill They would annihilate with the anti neutrinos those stars put out, at least I believe so. It's not just neutrinos though. Regular matter should also do the trick. Even at just a few atoms per cubic meter, that's still a very significant amount when talking about the scale of a galaxy.
I'm not an expert, I heard this somewhere else.
Does anti-energy exist as well? (Probably a stupid question)
I think that would be negative energy so ... Maybe?
Assumably there are anti bosons? So anti photons and anti W and Z or anti gluons etc, but I dunno.
Giannis Polychronopoulos I think energy always has a direction, so anti-energy is just energy in the opposite direction. Every action has an equal and opposite reaction.
Energy is a scalar, is it not?
Giannis Polychronopoulos It does exist, but not in anti-matter particles, because matter and anti-matter have the same properties except charge, but they have the same mass so their energy are the same too, because E=mc^2, and they have the same mass, so we will get the same energy. You will only get negative energy if you have negative mass.
i propose the theory that the big bang wasn't just the creation of this universe, it was the creation of duoverse in which the universe and the anti-universe were created and that when quantum particles pop in and out of our observable universe it's really just them getting pulled through space-time from the anti-universe, obviously i have little to no evidence for this, it's a highly hypothetical theory, but interesting non-the-less?
It is...
MIND=BLOWN
-MIND=-BLOWN
-BLOWN= antimatter+matter
antimatter+matter+blown=0
matter+blown=antimatter?
MIND=BLOWN
Jason Brody And also:
-MIND=antimatter+matter
antimatter+matter+MIND=0
MIND+matter=antimatter?
And that when drawing a graph with X,Y and Z, there's negative values, maybe the anti-matter universe could be traveling along a reverse time scale (not saying that the people there end their existence at conception, but rather they are just traveling in the opposite direction in time) and maybe that creating antimatter through matter collision is actually our universe creating 2 quantum particles of matter on top of each other, and the anti-universe at the exact same moment doing the same with anti-matter and that because the quantum particles are right on top of each other they are repelled so strongly that one gets pushed through into the opposite universe so the universe and anti-universe exchange the respective matter/anti-matter they created and energy is conserved by photons being given off, and maybe the big bang singularity is like a tear in the fabric of space-time where as our universe expands the anti-universe shrinks (being pulled back into the singularity) which supports the reverse time flow possibly? and that when the ant-universe has re-compacted into that one singularity again the repulsive force of like charges forces it to explode and it can do so because our universe at the same time would have reached it's maximum expansion and then begun to shrink again as the anti-universe expands, please feel free to add to this people! :)
TheHarleyEvans Tachyons travel faster than the speed of light, and thus back in time. This might imply that all particles in an anti-universe are highly excited?
If there's two universe, called "matter universe" and "anti-matter universe", Which "matter" and "anti-matter" universes are the opposite side of each other. We're in "matter universe", but why we called our universe a "matter" one and called other universe "anti-matter" one?
In their perspective, people in that "anti-matter" also called their universe "matter" and called our universe "anti-matter"
Is that mean we're in "matter" and "anti-matter" at the same time?
Underrated comment
explaining qualia also matters, my simple atheist friends.
something as seemingly trivial as pain cannot be done by any physics, known, speculated or unknown. make me a robot that feels pain and I shall concede that God isn't real. hint: it cannot be done.
qualia proves the spiritual, however little your weak minds can handle the implications and therefore deny it.
What is that argument supposed to be? I can make a robot that feels pain very easily. i get a button that i hook up to a computer with a cable. Everytime i press it, i get a message on screen telling me "I am in pain".
Just like in our brains, except a lot simpler. We have nerves (button) that when stimulated in a certain way send a signal through a nerve (cable) to the brain (computer). There, the signal is interpreted, registered and reacted to by the brain. We register something hurting, chemical reactions take place releasing adrenalin etc. and we become aware of the pain.
Pain is just chemestry, this is no mystery. Also there are people that cant feel pain and they are just as human as everyone else en.wikipedia.org/wiki/Congenital_insensitivity_to_pain
MagnificentXXBastard so if the robot doesn't speak then it isn't in pain? is what you are describing actually pain... think a little further. As the genius computer scientist that I am, I probably wouldn't have said what I did if pain was that simple.
tomas, that the sensors fail, doesn't mean that the inherent capability for pain has gone. If I don't slap you in your face it doesn't mean that you are incapable of pain.
Make me a robot that feels pain and I shall concede that God isn't real. It cannot be done.
Dan Frederiksen
"Genius computer scientist", huh? I smell troll. Also, wtf has feeling pain that to do with God? It's not like its some unexplained, mysterious process. We know how it works from start to finish, we can influence it, increase the pain s.o. feels, nullify it, hallucinate pain etc.
In addition, how was the Computer-example different from real pain?
It has a receptor to detect it, it has the information "pain detected" send through a cable to the processor, there the signal gets analysed and interpreted -> we get a reaction. Where is the difference to a human? Only one is the reaction, and that merely for simplicity's sake. Our brain reacts to the pain by sending alarm signals and increasing the adrenaline output. The computer reacts by showing the message "I am in pain".
MagnificentXXBastard less talking, more thinking. go on. we know about the signalling and triggering of pain in our bodies but the actual pain we know nothing about. you have to be willing to see something new to see it. there is no chance I could be wrong about it.
0:08 = WE ALL MATTER!
Here's my take: The Big Bang contained equal amounts of both matter and antimatter, but, as is the nature of randomness, it wasn't evenly spread. Let's say for the sake of argument that the left side of the Big Bang just happened to contain more matter than antimatter, and the right side contained more antimatter.
On the left side of the universe, matter and antimatter kept annihilating each other until there was only matter left. The opposite happened on the right side. Now, one half contains only matter, and the other only antimatter, and there's much less stuff than there was when the Big Bang happened.
As the universe expands, every particle of matter that is travelling right is eventually obliterated, same for every particle of antimatter travelling left. And so, in a stable universe, the universe spreads one way, whereas the anti-universe spreads the other, and they just go further and further apart.
If we could FIND antimatter, we would *already* have been destroyed by it; the reason we don't find it is because the universe has existed for a long time and has become pretty stable by now.
That's what I figured.
*****
Less and less. As the universe grows more and more stable, the anti-universe just goes further apart from the pro-universe. Every particle travelling the wrong way is destroyed eventually, wheras every particle travelling the correct way is safe from annihilation forever, so the two halves of the whole universe must spread in opposite directions eventually. And the center will be empty. Also, since the two halves are not equal, annihilation will not likely happen exactly in the center.
Though, I'm not going to claim I'm a professor in this subject. It just seems to make so much sense. High chance I'm wrong about this.
That's what I had in mind the parts of the universe we can't see most likely destroyed itself. Another theory is that another part of the universe contains much more antimatter than matter causing a reaction similar to the Big Bang. Damn it seems like all the answers would b possible if we could see more of the universe.
I like your theory :) IT would answer that qestion but it raises another one, for them to spread, they need to have all started for a specific point, antimatter and matter int he same place, all unleased at once, it would stand to reasont hat one would overcome the other. Perhaps it all occourec before the big bang even started.
Perhaps we ARE the antimatter side, and the matter side is what we call 'antimatter'
Try to think about that without huting yourself ;)
The problem I have is that the law of equivalence exchange is put into play. If for every matter there's antimatter it doesn't add up I think it's funny our generation may find the answer but creates a new problem to solve. I have hope that eventually humans will explore enough of the universe to understand it completely.
Ok, so I have a question, and then a theoretical question. Photons are their own antiparticle, since they have no charge. So this could also mean that neutrons are their own antiparticle since they also have no charge, right? I am just a bit confused by the idea of breaking down empty space to form two opposing pieces. In mathematical theory it makes sense, but physically I do not understand. What exactly is one breaking down, and what is it breaking down into? Also my other question, since hydrogen and antihydrogen are both composed of two particles, only with the charges of them switched. IE, a positive proton and a negative electron, and then a negative antiproton and a positive positron. Because of the reversed bonding of these particles, do you think this would mean antimatter has really strange and interesting chemistry? Or do you think it would be the same as normal matter? Thanks, sorry for the big questions. This video just really has me thinking. haha
Asking questions is always a good thing in science, so to adress them: Neutrons have at large no charge, but are made up of smaller particles, so called quarks. These do have charge, it's just that, in the case of a neutron, these equal each other out (-1/3-1/3+2/3 =0). So you could create a particle made from the corresponding anti-quarks and you'd have an anti-neutron.
Then, the "anti-hydrogen" he presented wasn't actually an anti-hydrogen. It's just the closest we can create to an actual one,but an actual anti-hydrogen atom would not have a positron as in the middle, but instead an anti-proton. Protons are, like neutrons, made from quarks, just that here they come together to create a positive charge (2/3+2/3-1/3 = 1).
Lastly, the chemistry would work the exact same, since antimatter interacts with antimatter the same as matter interacts with matter.
I hope i could answer your questions and eventhough I'm pretty late I hope I could help. If I did a poor job as explaining something and you'd like to know more, I'd be happy to help. Cheers!
Top tier stuff.
WOW. there really needs a part 2 to this
Better than TedEd.
A person from antiuniverse: why aren't there enough matter around ++
It really upsets me to see just how truly ignorant some people are about science. Still at this day in age. Especially in the fields of mathematics, physics, chemistry, biology, medicine, philosophy, psychology and cosmology. Always making false assumptions due to a sheer lack of knowledge in the particular subject you are commenting about. It's great that you are asking these questions, but please, for the love of god do not ask them in a comment on a youtube video. You will NEVER get the response you're looking for. Instead, go talk to your nearest teachers, academia professors, professionals in the work field, people with the experience and knowledge to help answer any question you may have. If you can't do that, then go to professional scientific forums where many PhD/Graduate students and degree holders would be gladly to answer your questions there too.
As a third year Chemistry major, who has a complete love for understanding the world we live in, it pains me to see the only thing people seem to care about are answers to particular questions in which we are unable to answer at this point in time.We are all looking for answers, yes, but at this point in time, we are unable to do so. So arguing about it over and over and over and over again is just pointless. It isn't going to advance progress any faster by doing so.
The beauty of science is truly remarkable. Take water for example. H2O. What do we know about water? Well, to most, we know that it covers nearly 3/4 of our planet, we are able to swim in it, we are able to drink, we know it changes phases depending on temperature and we know it's also essential to maintain normal biological functions throughout our bodies.
To chemists however, water is so much more than what I described above. Take a water molecule for example. Oxidation states, Chemical bonding, Polarity and Net dipole moments, Molecular geometry and Bond angles, Molecular Orbital diagrams, Hydrogen bonding, Wavefunctions, Phase changes, Triple and Critical points, Orbital density functions, Frontier orbital interactions,Thermal conductivity, Solubility, Entropy, Enthalpy, Amphoterism, Acidity and Basicity are all properties that chemists used to explain the nature of water.
A Biochemist, on the other hand, could tell you how water functions inside the body.
Physicists use Physics and Mathematics (mostly vector calculus and differential equations) to explain the kinematics and dynamics of fluid flow (or the way in which liquids (or water in this case) moves through time and space).
The point is that what people think they may know about something that seems to be common knowledge (such as knowing what water actually is, how it's important to everyday life, and how describing it's motion can be used to solve various problems throughout various fields of engineering to help benefit modern day human life) may in fact be actually something they could learn and benefit a lot from. Never stop asking questions. Just go about asking them in the right way. Thank you.
Dear Poster or anyone - Please help clarify this issue. An electron has a charger of -1. A proton has a charge of +1. Yet, in the hydrogen atom, the electron does not fall in and touch the proton and annihilate the entire system. Rather, the electron's probability wave superpositions around the nucleus, creating probability clouds (orbitals) of existence and null around the nucleus. Likewise, antimatter differs from matter in ONLY its charge. Therefore, why can't we contain antimatter using orbitals in a matter-antimatter system? Why is containing antimatter so difficult?
i am not an expert, do not take me for granted but i think it has to do with the amount of matter which crashes with anti matter. although i am not sure why can't we have a stable anti water mollecule next to a standard water molecule, because shouldn't the positron cancel out the electrone of another water mollecile and the anti proton cancrl out with the proton? or is that absurd and they just annhilate each other, the p+ with the e- and the P+ with the anti proton?
Well, there are bound matter-antimatter states, such as positronium - an electron-positron pair. But these are unstable and will annihilate in a fraction of a second.
A minor correction: An electron will not annihilate with a proton. In some radioactive atoms it is indeed possible for an electron to fall into the atom (in a process reverse to beta decay); this will transform a proton into a neutron (and release a neutrino).
[edit] I think that the ultimate reason why an atom's electron does not normally fall into the nucleus and combine with the proton is that the proton-electron pair is more stable (has less energy) than a neutron. That's also why a free neutron decays into a proton, and not the other way round.
protons and electrons are two different things. consider it this way. antimatter is kind of like the doppelganger theory (the one of a person from an alternate universe. theoretical, don't take it seriously). if you met yourself from that alternate universe, your mirror image, they would (theoretically, of course) annihilate each other. but, protons and electrons are kind of like a person from our universe that looks exactly like you, talks like you, shares your interests, everything. if you touched him, you wouldn't cancel each other out. confusing, or cleared up?
The probability of the electrons being inside the nucleus isn't 0 and that's the whole point. With proton-electron-pairs there is no problem, because they don't annihilate. But in positronium, (or protonium or any other matter-antimatter-atom for that matter :D) this probability means that eventually this annihilation will take place.
thing is, we cannot contain it. When created you have to keep it in a strong magnetic field( to eliminate movement) and vacuum, however absolute vacumm cannot exist ( in vacuum spontaneously matter and and antimatter annhilate each other), so in the end of the day its not about creating anti-hydrogen, its about containing it. -I think :P
Is there such thing as anti-light?
No. Photons are their own antiparticles.
Photons have no charge, so it's like the 0 = -0 scenario. Like in mathematics, -0 doesn't exist.
It does, it's called normal light.
this can only mean one thing "black holes" are the antimatter! riddle solved
Black hole is a totally different subject and iif you think that black holes are made from antimatter that is wrong because black hole suck objects into the singularity and doesn't anahaliete matter( I wrote anahaliete wrongs don't judge me)
+Tariq Samaien Annihilate :) For next time ^^
like a black hole, you mean?
@@tariqtariq20031 Well black holes don't actually "suck" anything. Things fall into it.. there's no pulling etc involved. In relativistic physics gravity isn't a force but a representation of the curvature of space time.
Btw, what's the antimatter equivalent to antimony?
antiantimony or just mony?
fascinating
Here is a motivational quote that i made, it is silly but idc
"Become like a positive positron to annihilate the negativity of electrons!"
Thanks for the video! Questions:
1. If a photon is its own anti-particle, does it annihilate when it meets another photon?
2. Neutrons apparently have antineutrons, although since the neutron is electrically neutral it can’t have opposite charge. Does this mean there’s something else besides charge that would cause a particle and anti-particle to annihilate when they meet?
A neutron is made of two down quarks and an up quark, whereas an anti-neutron is made of the antimatter versions of these. While the neutron has no charge, the constituent quarks do (they just sum to zero).
What happened when a normal matter man and and antimatter women met?
They Banged!!!
physics: 0=-0
math: wait that's iligal
So quick question: When Matter and Antimatter meet and annihilate each other, does it actually destroy the matter and violate the law of conservation of matter?
according to enstein's famous E = mc² equation, a lot of energy is equivalent to a little bit of mass. the mass of the particles is just converted to an equivalent amount of energy in the form of photons
@@somemagellanic "A lot of energy is equivalent to a little bit of mass"
Fun fact: a single penny has the same energy equivalent as 4 Hiroshima bombs
Didn’t understand a word
Good video, but godDAMN can I get a nanosecond to read? I mean, I get this is entertainment for the masses, and it needs to be quick and punchy, but some of us actually care about learning the details, and are able to understand concepts above basic algebra and “2+(-2)=0”. If you ever read this, maybe it would be possible to have a second channel like 10-minute physics or something that just goes a little more in-depth and takes a little longer to explain complex topics like this.
(We are destroyed by antimatter bad thing, but we can't be destroyed good thing, but it doesn't do much damage than big bang, )-what a beautiful mind fuck...!
Who said when they meet they blow? Anticipation of violence. That's an equation, scientist help us. We need to know please.
Wait so by splitting zero, you are creating something out of nothing..? Is there another universe parallel to ours with antimatter? In your face Christians?
Pov: you just saw the video 1 gram of this cost 2700$ trillion and now you came here
Now I am into astronomy and I have fallen behind because of lockdown but this is the only thing I do not believe exists. If everything in the universe is matter and these are anti particles the whole universe would be destroyed as soon as this stuff forms in an instant.
Someone correct me if I am wrong.
I am a young aspiring astronomer so do not get at me.
So there is an opposite me who is happy has a girlfriend and his parents are proud of?
Let's not get carried away and stay in reality.
He talked so fast, i had to slow the speed
How do you know if the other galaxies are not made of anti-matter? There may be as much matter as anti-matter in the universe. But not the Milky way.
I think universe has 2 sides,one side we have what we humans call matter,another other,anti-matter separated by a very strong force
If a human touches anti-matter will the human just disappear or will nothing happen
So you mean our life is matter and we need to find antimatter to solve our matter which we disappear from existen and any connection from the Universe ? fuck yeah !
Why it's callled "Matter" if it's "Anti-Anti-Matter"??
Excellent info but you talk faster.......slow down a little bit next time.
Hm........anti......kay...
How about drinking....anti water......To bring more thirst....😅😅
If Electrons become Positrons, wouldn’t Protons become Conatons? Negatons? Electons?😓
