"Anti-proton" should be called "negatron"

The beauty of Science is that it is not ashamed to admit that it still doesn't have all the answers. Giving us more reason to be curious, to learn and to explore. :)

"What happened to antimatter? We don't know." Great video...

So are matter and anti-matter same? Ted Ed: Yesn't

so if I drank anti-water I would explode?

What happened to antimatter? It's simple. *Antimatter has left the chat*

2013, We just dunno the answer. 2015, We just dunno the answer. 2017, We just dunno the answer. 2019, We just dunno the answer. Damn.

The aliens stole it all.

Perhaps all the antimatter went the other direction. Allow me to explain. (Note that I will be using the terms "east" and "west". These directions have no meaning in the context of the universe, so just point in any direction. That's east. The opposite direction is west.) When the big bang occurred, immense amounts of particles and antiparticles were made, and most annihilated each other. But, due to random variance, slightly more matter went east, and slightly more antimatter went west. It wouldn't take too long before all the eastward antimatter was annihilated with the dominant matter, and vice versa in the west. The end result would be a bubble of matter in the east and a bubble of antimatter in the west, separated by an extreme distance. Both would have an exactly equal mass.

maybe to other living things on the other side of the universe our matter is anti-matter to them and we are actually the ones that are living in an anti-matter world

"mommy, I need a gram of antimatter" "All right,how much does it cost(at most a dollar)?" "1000000000000000000000000000000000000 dollars only"

Also, who the hell would dislike this video. This is awesome.

An excellent presentation. Clear and beautifully illustrated. Something which has been frustrating me for a while is now crystal clear. Thank you Professor Landua.

What if there are 2 universe created in big bang? 1 is our universe which have matter? Another one contain anti matter . Just like the Ying- Yang pattern.

a little knowledge is a very dangerous thing

Us farming a theoretical planet made up antimatter would be silly. Anything we used to farm it would cause it to explode.

if we treat antimatter as matter going in the wrong direction in regards to time then it went out the other side of the big bang.

Short answer: we must be incredibly rare and beautiful.

We are _unlucky_ that tiny asymmetry existed.

When in Italian restaurants I always think that pasti and anti-pasti combined will cause a huge explosion. The naming is rather peculiar...

But how is that possible? If there is an exact 50/50, there is an *EXACT 50/50*, how could you say there was an asymmetry

What if there is a ton of antimatter out there, but it's just over 14 billion light years away, so we can't see it?

Please just change the name from 'antiproton' to 'negatron', it would just make everything so much nicer.

That music at the beginning and ending is soooooo pleasing!!!!!!

I'm no Physicist but rather than people thinking of some sort of "antimatter planet" in our visible universe, isn't it entirely possible that, as our universe formed out of matter, a separate, identical universe formed out of antimatter? Although I guess that's the idea behind Parallel Universes?

Thank you for this video. I've always been interested in antimatter and this has explained a lot to me.

This is by far one of the more interesting questions in science that doesn't require pure speculation or for it to only work out mathematically. We are actually able to create this shit and that should be enough to get an answer in the near future! Super excited about this endeavor.

Ooooh okay so “antimatter” isn’t actually some physics breaking mater like I thought it was, but just a subatomic particle with different properties than other common particles.

Oh, thanks for your explanations xD But still, we know almost nothing about dark matter, isn't it really possible that there's a relation with anti-matter and dark matter?

Did I just hear "Hentai-matters"?

I have to say, the animations were flawless. 👌

Time Traveler: This is anti-matter gold bar Me: When since human can have these things? Time Traveler: After we raid the Area 51 Me: :o

It uhhh.... Ummmm.... I forgot tho Whatever, it doesn't *_MATTER_*

Has anyone read Angels and Demons. It has got some stuff about antimatter. A GREAT READ.

Beautifully explained! Thanks

The PARTICLE TRAIN! Previously I suggested that eternal photons made electron positron pairs, (as well as all standard model particles). Here's how. Start with a PARTICLE TRAIN, each time you add an electron or positron car to the train, you get a new particle. The only rule is the cars have to alternate from electron to positron. Think of a wave with trough always alternating with crest. Photons as electron positron pairs could make the main parts of an atom in the brief time after the Big Bang under those extreme and never repeated conditions. Charges are the cars on our particle train. Positive positron (+), Negative electron (-). Positron (+) Electron (-) Photon (+) (-) Proton (+) (-) (+) Anti Proton (-) (+) (-) Neutron (+) (-) (+) (-) Anti Neutron (-) (+) (-)(+) . The PROTONS and NEUTRONS are made from ELECTRONS and POSITRONS! When this production of particles was over, most anti particles with charge; positrons, and anti protons, didn't exist on their own. They were LOCKED INTO PROTONS OR NEUTRONS. That way conservation of charge was maintained. That also explains the MISSING ANTI MATTER PROBLEM! This from Wikipedia article Matter Creation: It is possible to create all fundamental particles in the standard model, including quarks, leptons and bosons using photons of varying energies above some minimum threshold, whether directly (by pair production), or by decay of the intermediate particle (such as a W− boson decaying to form an electron and an electron-antineutrino).

3:42 You see when the universe got created there were equal amounts of both but as you said they react with each other and cancel each other. So my theory is that there was slightly more matter than anti-matter which can be possible by the composition of the creation of the big bang etc. But after anti-matter got canceled the remaining matter has become the universe we know now. As you said, maybe the cause of the big-bang itself was the collision of anti-matter and matter. anti-matter cannot exist in this universe anymore as it would be cancelled out by the matter in it. Of course I could be wrong and maybe this mysterious dark matter has been protecting it or god knows. Soooooooo that's my theory

so I had this idea. Our visible universe is mainly matter with very little antimatter. Now, what if there's another part of the universe that we can't see yet that's the opposite. Mainly antimatter with traces of matter. Wouldn't that explain the missing antimatter? I don't think it can be proven, not easily but it just hit me the other day...

Keyword: visible. There is no significant concentration of antimatter in the VISIBLE universe. that means that, in theory, there is a small chance that all the matter went in one direction at near the speed of light, and the antimatter in the other at the same speed. that means, if we are near the leading edge of the matter "wave", that we could see only the matter, and not the antimatter, because all the antimatter in our "vision" that direction would have annihilated with the matter that would be equally concentrated there.

extremely instructive video !! Thank you !

How could we mine antimatter? If we found a planet of the stuff the shouvel would destroy itself.

We cannot be left overs... Energy was equally divided into matter. How come suddenly there was an extra matter..

Maybe you should consider reading bedtime storys. You have a nice soothing, calm voice.

Finally KZfaq recommended me this video after 8 years.

What happend to anti-matter Gone reduced to atoms

That was some real bruh pronunciation lmao

There is a theory that neutrinos are the reason for matter existing above antimatter as they have mass. Although it is 500,000 times less mas than an electron, it is believed by some that the miniscule imbalance of mass to 'antimass' is the the reason that matter is able to survive.

Thank You for illustrating the reasons given in "A brief history of time" by Steven Hawkings

There is something relation between antimatter and other dimensions

If hydrogen and anti-gold collide, do they produce some different element (maybe iron or something)? I like to think of it like numbers, so a hydrogen would be 1, and anti hydrogen would be -1, 1 + -1 = 0 (or destroyed, changed into energy). Now imagine anti-gold is -26, this would be 1 + -26 = -25, so would this produce a little bit of energy but also anti-something (maybe anti-manganese)?

Oh man I love science, after a long explanation answer was "we just don't know" Great video

Maybe because of THIS: X Bostons, the heaviest particle to ever exist in the universe decayed into lighter particles when the universe got too cold for it. The X Boston and its antimatter counterpart decayed into *BOTH* lighter matter and antimatter particles but there was more matter particles combined than all the antimatter particles combined

Antamatta, not antimatter

So... if time slows down as gravity increases and the universe is infinite in size. Would that not mean that the big bang had no beginning? I'd like to think of it as like a logarithmic function of sort. As gravity reaches infinity going back in time, so does time. It never reaches its asymptotes. Which could give meaning to the heat death of the universe too. But in those terms... wouldn't it mirror if you were to cross the asymptotes? But then, if it is a mirror, and you add both sides of the graph together... you get 0. Conforming to the first law of thermodynamics? Could that be the divide between matter and antimatter? Could that be the reason for the expansion of the universe getting faster?

One idea why we only see matter around us is we live in a corner of the infinite universe that it just so happens not to be evenly distributed and has yet to meet and be annihilated with antimatter yet. Its like those left over dry pockets you have left in wet cake batter after you have mixed the ingredients for a minute or two.

So i am here to see answer to that question, and all i get is some elementary school lecture about antimatter. With question just repeated at the end. Great success.

2:55 SO BRINGING A SPACE SHUTTLE INTO ORBIT EATS UP AS MUCH AS ENERGY AS 1000 TIMES EARTH-TOUR WITH A CAR? hmm nasa?

I personally think that after late 20th and 21st century, physics is almost stagnant without much significant progress in our understanding of our world. There aren't many groundbreaking discoveries like those made by Schrodienger or Einstein.

5:00 video, sums up to 'We don't know the answer.' Damn OK.

If we are going off the explanation in the video, antimatter by itself has the same energy as matter because the two are equal and opposite. Therefore, if matter has very little energy, antimatter also has very little energy. It's the reaction between the two that create energy.

Spoiler: We don't know why.

Off topic but seriously, Rolf Landua has a very soothing speech pattern and voice

He says just a second later, but it actually took much less than a second for matter and antimatter to annihilate each other.

what happened to antimatter? scientists: Yes.

I came for the fidget spinners in the thumbnail

what if matter is actually antimatter and antimatter matter?

Was the law of *particle entanglement* already present from the very beggining of the Universe, at the earliest moment of the Big Bang, or did it only come into play once it all settled? Does anyone know the answer to that? Thanks in advance.

The FULL lesson is exactly 1 second longer! Don't miss it, hahaha.

I like this view of the big bang (I think I saw Hitchens speak of this but idk) At first there was nothing, and then the universe came into existence, and at the same time an anti universe came into existence, all the anti matter going there. Mathematically, this is the way you can get something from nothing. You are given 0. You can add +1 and -1 to it, and you still have 0. 0=1+ (-1), 0=Universe + Antiverse.

I can feel his spit coming through the mic into my headphones and then into my ears

The narration + the animation + lack of music = creepiest video ever

ted ed!! can you please make a video about quantum physics????

Sorry, but this is video title is just inapropriate. 5 minutes video, where 4:30 is the introduction and the answer to the TITLE question is simple "we don't know". Did not expect that from TED-Ed video.

I see, thats why we have parallel univers and its made up of anti matter🤯

Flexin Angel's and Demons by Dan Brown where I first read about anti-matter and CERN

259th video in a row that promises an answer and ends with: "Bruh, i no understand any physics, but thanks for clicking"

I like science, but I won't believe everything comes from nothing. 0=1-1, 1-1=0 let's say zero stands for nothing, and 1 stands for everything that exists (energy, matter ect...) we cannot get 1 from 0, it's just impossible, whether you add, substract, divide, or multiply, we can only get zero from 1, 1-1 and every number added to its opposite eg: infinity-infinity=0. This is the magical theory!!!! Either you believe in a supernatural being, or you believe super atomic particles have always existed. I believe in God, and I don't think people should judge me, because I don't judge those who don't believe

What if antimatter turned into dark matter and dark energy? It would sound plausible but there's too much dark matter compared to matter, so it can't account for antimatter.

I think particles like photons are in orbit likely with dark or anti matter particles giving them an apparent axial wave or circular helical wave as they travel, depending on the orientation of their orbit. I think light travels thru the 2 polarized filters when a 3rd is introduced at 45 degrees because some particle orbits are deflected into that orientation or circular and pass thru. This would explain the double slit results too.

I'm guessing that, the matter did collide with each other, but didn't actually turn back into energy. It got stripped and the universe turned into a cloud of quarks and electrons instead of protons, neutrons, and electrons. But for the same asymmetry reason ( which we still don't know ), the matter outnumbered the antimatter, so all the reaction didn't allow antiparticles to form antiatoms. But matter was a little more, so little matter did form. And over time, all the antimatter in the universe got completely destroyed, because of reaction with matter. Or maybe it turned into dark matter, which we don't know a lot about either. Either way, matter could finally collect in huge amounts and form stars, planets, and galaxies. But I could be wrong.

I hate videos like this, they tell you luring, interesting information, but the answer is "We don't know" at the end.

yeah, science put the blame on luck! bravo

Excellent explanation!

I knew we were a mistake..now i have an explanation to support it! :P

Who's here cause of DJ Dan Mawson

Any second now, someone will bring religion into this. Just wait for it..

I just came to this video to comment that his name should have been Rofl for the video to be interesting enough to click and watch

One conceivable answer: There is no asymmetry. In any region of space there will be matter, antimatter or no matter. The region of space visible from Earth (our visible universe) is one in which matter prevailed. There are other massive regions of space where antimatter prevailed. Regions of space with matter or antimatter are separated by massive regions with no matter at all. It's conceivable that most regions of space have no matter and there are anomalous specs of space (e.g., our visible universe) with either matter or antimatter.

Science is so brave to admit it doesn’t know the answer. Religion, unlike, says it knows all bcos Jesus/Allah etc created it that way. End of critical thinking.

what if there is an alien race made of anti matter and think they are they regular matter and us the antimatter? we should build a spaceship so we may correct them.

I have theory. The energy that caused the big bang wasn't a condense ball of energy but lots of energy hitting each other at the same time. But the catch is that it happened multiple times but at a smaller scale. Some of the matter left over from smaller occasions of that happening have survived, before all the matter from the big bang killed itself off. leaving behind some extra matter without any anti matter to kill it off. That might also explain why the universe is expanding. The energy outside of the universe hits each other creating matter that goes inside the universe. Making it look like its expanding it just getting bigger.

The answer to the TITLE question "What happened to Anti-matter?" is. > "Almost all of the anti-matter got annihilated with normal matter, in the early stages of the Big Bang. We can still observe the radiations emitted during the event." The video ends in a "We still don't know." to another question that raises. "Why is there more of normal matter than anti-matter?". While there are some hypothesis, more experiments and a lot of funding is required to answer this question.

Oh my goodness, this guy is wrong! The reason why there is not alot of anti matter in the universe, is because before the big bang, there was MORE matter than antimatter in these collisions.The reason the big bang began was due to these collisions which released massive amounts of energy, giving spark to inflation. What do i mean? Well for every 2000 antimatter particles, there were 2001 matter particles- the + 2000 and the -2000 canceled out, but the leftovers remained. These leftovers would be enough to construct everything we see in the physical universe today. - the stars,planets,galaxies... There is almost no antimatter for that sole reason. Basic physics.

We dont know the answer... Therefore... *Drumroll* Therefore... *Drumroll* Therefore... *Drumroll* *GOD DID IT * *trollface*

“Like money, energy has a huge exchange rate” yeah you got that right

You explained it perfectly

So we got lucky when anti matter "lost the battle" against matter, then we got lucky when our galaxy hasn't collided with another, we also got "lucky" when our solar system was created in just right place in our galaxy not too far in and not too far out We also got "lucky" that the Earth is a perfect 93 million miles away from the Sun, any farther we would freeze and any closer we would burn. We also got "lucky" that we have planetary neighbors like Jupiter and Saturn that obsorb the majority of the interstellar impacts of meteors and astroids, then we got "lucky that our Earth is tilted on a 23.5° axis so we can have changing seasons, we also got "lucky" that DNA and RNA and essential amino acids were spontaneously formed in some goo and then reacred to gether to form a cell and that cell evolved into the many different complex animals of that time, they further evloved and now you have us...I disagree ten fold, Jehovah God is the creator of all things.

Thanks for your video! Love from Sweden!

Very nice and informational video Can you please answer that the COSMIC MICRO-WAVE BACKGROUND RADIATION which we see today are the radiations leftover of matter and antimatter annihilation battle ??
