This video is a bit different than my usual fare on this channel - less casual chat and more "documentary" style! I feel like everything I've learnt over the past 18 months making content (and everything Editing Becky has learnt) has all come together for this video. I know it's not perfect but I'm really proud of it - so I hope you all like it too 🤗 Edit: Voice was at 100%, music at 15% - I checked levels on headphone and computer speakers and it sounded great. If music was too loud (perhaps a TV) check your audio settings 👍 Edit: I said antimatter has the opposite value for all properties at the beginning - note this doesn’t include the mass 👍

Hi Dr. Becky! Reading your introduction I noticed that you used the word "learnt"? I'm thinking that you really meant to use "learned". Just saying....BTW, that was a very good video....👍👍
Assuming a cup to be 236ml (=1 us cup) for a cup of tea and 23°C (standard room temperature) as your starting temperature, you actually need ~70 BTU to heat that volume of water to 100°C , just in case someone was curious
I’m amazed how quickly you went from starting with simple videos in a desk to making such a good mini-documentary, congratulations on such amazing work!
@@DrBecky Great documentary, very well produced. And, dare I say it, all the better for your having dropped the dreadful Australian Question Intonation that seems to be creeping into British English.
I haven’t finished watching yet, but I like the style. Good job with the timing on your cuts. Definitely different from your normal “desk side chats”. There’s room for both!
Hey Becky! Is it possible that some of the quarks are really anti-quarks, but are stable with other quarks? That way, they wouldn't meet their anti-quark, and this could be the solution to the question.
As a chemistry person who also loves physics, this is something I must know: Have they managed to create diatomic anti-hydrogen? That is, the molecular form/H2. Have we been able to observe positron bonding? I mean, as far as I'm aware it should behave identically to matter, but I'm so curious.
Don't have enough of it yet to create molecules. Record is something like 1000 atoms of antihydrogen - with that few they just don't really interact with each other.
I for one am fascinated by anti-matter. The idea that "Data's positronic brain" was a form of anti-matter!?!? just makes me shake my head. Luv it! Thanks Dr. Becky - another great video.
When you first announced it, I expected like, the nerdy version of the vacation slides Selma and Patty showed the Simpsons on the older episodes. But no - ever the educator, you went way above and beyond with this, and I'm really glad we got to share in with the wonder a bit as you asked the questions with us instead of just telling us they're trying to answer them. And the editing and everything is super, thanks for make.
Don't, There no such thing as anti matter, nor quantum anything. Its a funding rort No big bang, a light bulb does not emit a spray of electrons etc etc. Learn something real,
Physics and astrophysics are probably the most relevant fields of studies for humankind. However, have in mind that Dr. Becky and 95% of the physicists in the world base their theories, studies, experiments and predictions ON THE FAILED CURRENT STANDARD MODEL. The worst part is that every physicist that decides to work outside that FAILED MODEL, he or she is immediately put in the "crazy people box". This is the reason why there has not been any major breakthrough in physicists since Einstein, more than 90 years ago. If you go to study this, good luck, but have in mind that if you EVER attempt to do any real science, you will have all these people (including Dr. Becky) against you.
@@ETALAL so really why do you come to a channel like this if that's what you think? I really don't get it, like yes l agree there may be things that's aren't perfect in the current model and that some others should have more resources used to investigate them, but dude if you don't like her content then go somewhere else. Plenty of channels talking about other theories these days(one of the good things about social media and sites like UA-cam) granted some sound like they need to take their medication, but some really do have interesting concepts that should be explored more.
@@Jake12220 that is why I come here, to get other perspectives, to see how close minded some in the science community really are. So Matt do you have any papers from CERN that you would like to cite regarding the topic. We have wasted decades on this rubbish, some of the greatest minds in the UK like Eric Laithwaite must have died from shame at what has happened to our universities since the 1970s
Wow the trip of a lifetime, so very awesome. Love the format you presented this with very laid back and informative. Can’t wait till your next adventure
My crackpot hypotheses is that the total average across the whole universe comes out to equal matter and antimatter but our pocket of the universe had to have an asymmetry for us to exist. This pocket had to be of a certain size to give us enough time to develop. But now that we are here and no longer protected by the anthropic principal I’m expecting that at any moment a powerful gamma ray background will replace the microwave background as the edge of our matter bubble comes into view.
Your presenting style and editing is worthy of a professional documentary. Except they have a whole to produce the film and they have a whole team to get the end result. Please keep doing this :-)
Can anti-matter particles only annihilate with their exact counterpart? Or does, for example, a collision of a neutron and a positron "take away the neutron's electron" and leave a proton (and a bunch of energy)?
When not in a nucleus a neutron is very unstable and decays in about 15 minutes. The emitted electron is normal and will annihilate as usual. There is no indication that this decay can be induced by an interaction with a positron, however, the lifetime of neutron decay isn't one value, there are two different, accurately measured, values depending on how you do the measurement. There are several possible things that could trigger this result so it is not certain that this particular interaction won't occur. Nevertheless, in general, it's exact matches only.
'Annihilation' between an antiproton and a neutron, for example, does happen because they both contain up and down quarks - which are the things that will actually annihilate. Neutron-positron annihilation wouldn't happen because positrons don't contain up or down quarks and neutrons don't contain electrons.
Great video and awesome that Curiosity Stream is on board! I do have a couple questions, though. For the LHC, is it possible to have multiple streams running concurrently or just 2 for a single experiment? Do they have to make adjustments for the Earth's rotation and movement or is it an inherent side effect of controlling the stream that stabilizes the path?
You are turning into quite a force of nature yourself, Dr Becky. Your evolving production quality, the depth of information - while keeping it accessible and fun is just impressive. I must confess, my brain outgassed a bit while watching. It was confusingly trying to operate anti-matter as if it was dark matter thinking we surely know it has mass that happily dances with "our" gravity. Until I paid attention and remembered "ohhhh.....anti-matter....Not the kind of matter(s) Dr Becky normally talks about". The banana segment was fantastic. As a safety-conscious gentleman, I of course never bring a banana to bed to not risk being blasted to dust via beta-decay. But you reminded me of course that we are talking Beta^+ decay. Those bananas are actively trying to annihilate me during sleep. I had totally forgotten. :D I can not wait to meet my nephew again soon - to attack him with a bona fide anti-matter gun. (I promise I will not scare him from eating bananas). Such a wonderful way of being reminded of all the lovely science and questions one does not think about every day or every month.
Great video Becky! Very interesting (as far as I can keep up). Also compliments for the editing of the video and especially the visual animations, good job!
"Where is all the Antimatter?" That sounds like an accusation to me and I can tell you that I haven't got it! That's not to say I haven't tried to get it; but, boy does it hurt trying to snatch this stuff! Take my word for it, someone else has it. Me, I'm more interested getting my hands on a What'samatter.
@@olik136 Thank goodness someone came clean on this. I kept seeing Dr. B.'s accusing eye looking at me with extreme disapproval. As you know, astronomers can see to the ends of the universe so there was no place I could hide. You did the right thing O.K.; so, tell you what: you get all the Antimatter you can snatch but I get all the What'samatter. Regarding the pens issue, I recommend you put all your money into buying stock in pen manufacturing enterprises. You will make yourself fabulously wealthy but keep in mind all the hearts you will break by disappearing all those beloved writing implements.
@@LuisAldamiz but.. but... aren't bananas proof of design?.. why else would the curved shape fit so well in a human hand and be so easy to peel?... Oh yeah, that's right. Bananas were basically straight(or flat) 100 years ago 🤦♂️🤣 Bananas are evil .
Dr. Becky - "Nothing to worry about" Me - "You conveniently failed to address the 'Cavern Evacuation' button on the control panel" 😀 Very cool and informative video. Thanks!
For others like me who don't really get how this all works out: One thing I wondered about and looked up is: Wouldn't annihilation keep producing more new pairs of particles and anti particles of smaller types. For someone like me who doesn't know much about the particles, I found the answer and the reason it becomes photons in form of gamma rays is because photons have no anti particle, they are neutral and don't interact in the relevant ways, so they are essentially their own anti particle. In the cases where they do though, all these reactions should produce the exact same amount of particles and anti particles, and as far as scientists can tell from experiments, they always do. But, if that was the case the big bang would have produced all manner of particle and anti particle pairs that came together, and annihilated, and the entire universe then would be nothing but light... So something is asymmetric and a bit fishy, hence the topic of this great video!
Really it's just the electric charge that is opposite. All other physical and quantum properties are the same between matter and antimatter, as far as we know.
I really, really enjoyed this style of video from you. So well put together, very entertaining to watch and a great departure from your normal videos. Love to see some more like this!
Love your videos Dr. Becky. This one is NO exception! Would love to hear more interviews with the staff on most plausible theories and if the evidence thus far favors any particular one. Thank you dear for all the wonderful knowledge you give us, even if said knowledge leads to more questions than answers. Please keep on keeping on. JT
Holy production value Batman. This video's quality is a cut above the rest. I don't know what you did -- but compared to your early videos where the focus or audio was glitchy--- WOW. This is very professional. Nice job!
For that we will need to build an even larger hadron collider, one that spans the entire circumference of Earth. Also the answer is (spoiler warning): 42.
Two questions for you guys that have always confused me about antimatter. First how exactly do you get anti-neutrons? I mean take an electron and mush a positive charge into it and you get a positron and vice versa for the anti proton I can grasp but I don’t understand how you can get an anti version of something with no charge. Second question is if you take an anti hydrogen atom and smash it into a larger atom of regular matter does the whole atom get consumed or just a single proton and electron? So let say you shoot a stream of anti hydrogen atom into a bar of lead would you eventually end up with a bar of Thallium (assuming you could only have each atom of the lead interact with a single anti hydrogen) or would you end up with nothing at all but a large quantity of energy?
The word positron long predates Star Trek. I believe that Isaac Asimov invented the word in his Robot series which he began to write in the late 1930s, early 1940s. His version of robots were controlled thru the use of “positronic” brains, manufactured by the fictional US Robotics. By the way, he also coined the word “robotics.” How’s that for having an impact on Science Fiction !!
Spok Haha - there should be at least a few others that know this stuff. As you know there are tons of Star Trek fans around, and there should be at least a few (elderly) Asimov fans left in the world. Thanks for writing. Live long and prosper !
I clicked on the new Dr Becky video as soon as it came up, but I couldn't watch it. With my hearing loss, the background music overwhelms the spoken words.
One upvote for Star Trek, one upvote for on location reporting, one upvote for props, one upvote for awesome simulation graphics... I'm way over my upvote quota and I haven't even gotten to content.
We basically group matter and antimatter by "what exists around us" and "what only exists if we create it in a lab". But for particles from which we can only produce the particle _and_ its anti-particle in an accelerator, how do we define which one is the anti variant? Why don't we group them by physical properties, like charge? Wouldn't it make sense to have protons and positrons in the same group? Is there any property that protons and electrons have in common, but positrons and anti-protons don't?
You could group them by charge if you wanted - they're called 'positive particles' and 'negative particles' instead of 'matter particles' and 'antimatter particles'. Whatever property you're interested in determines which property you'll group them by.
I'm not a physicist so maybe this is a dumb question. I have previously learned that anti-matter can be seen as normal matter going "backwards" in time. What happens if normal matter is "flipped" in another dimension (not time)? Would it turn into anti-matter?
Reinfallt I am a physicist and I asked the same question. It seems to keep on disappearing off this list of questions though. Glad that you’re seems to have stuck
"LHCB sees where the antimatter's gone. ALICE looks at collisions of lead ions." -- alpinekat Stuck in my brain. Thanks for helping me to understand more!
As you were patting that bit of the detector (14:08), I couldn't help but compare it to one of your "patting the telescope" photos ... That detector is perhaps the largest Microscope on earth. Great video!
Dr. Becky! What a great series! Thanks. I particularly liked this one. I worked at Brookhaven Nat Lab helping physicists with their 'maths problems' and computer programs used to 'detect events'. This program showed a picture of an event in the BNL Bubble Chamber. I met a friend through our work on the bubble chamber. Later he went on to work on the designs for the superconducting magnets at CERN. Several of his patents are used there. I did a little work at CERN, too, when they were having some problems calculating PI out to 100,000 decimal digits. Cheers. Thanks for the great work.
At the start of the video I was thinking 'yes I know about that part, but what about gravity?'. Now I know I have to be a little bit more patient :) Great video!
A year from now you'll be on all the late night TV shows explaining why antimatter is so cool. I hope this is what you want because you're an unstoppable force with a great gift for this (and painting fingernails).
I don't know anything about anti matter as I'm more of a BH enthusiast, but this video made me have an idea about it. Thanks for the interesting video, Dr. Becky.
Dr. Becky, another very well done content. Bloopers portion suggested addition to the dude at CERN. "If its not working...plug it in". Even though I know this axiom well and preach it, I'm embarrassed to say It still ends up 10th on the list even after my soft & hard resets.
Very interesting. I have seen several videos about lhc but all were talking about the other detectors and higgs boson, first time I'm hearing about lhbc and antimatter. This new format is great. Thanks for your work and sharing. Love&gratitude.
Thanks for taking us into CERN! Amazing things happening there, great to have an insider's glimpse. Your anti-gravity question reflects a question I have - are there, or is there a search (or even a need to search) for anti-bosons? I have not read anything about that yet.
Incredible how 2 different people have a lot of different things to offer about the same topic, both you and "Physics Girl" made a video about antimatter at CERN, yet, totally different stuff, and you can learn a lot from both, and that's exactly why I follow several physics channels...

I really, really enjoyed this style of video from you. So well put together, very entertaining to watch and a great departure from your normal videos. Love to see some more like this!
14:03 Ah, I get it now. The Rum is made of antimatter.
Love your videos Dr. Becky. This one is NO exception! Would love to hear more interviews with the staff on most plausible theories and if the evidence thus far favors any particular one.
Thank you dear for all the wonderful knowledge you give us, even if said knowledge leads to more questions than answers. Please keep on keeping on.

It's in the enterprise warp core.
Now where have the dilithium crystals gone?
Dr Becky - this is the best video. Wonderful wonderful work. Very excited to see more of this more documentary style!
Your face was like that of a kid in a toy store all the time :-)
Holy production value Batman. This video's quality is a cut above the rest. I don't know what you did -- but compared to your early videos where the focus or audio was glitchy--- WOW. This is very professional. Nice job!
But what about the *antidarkmatter*? ;)
Light matter?
Good question!
at least there *probably* isn't antidarkenergy
For that we will need to build an even larger hadron collider, one that spans the entire circumference of Earth.
Also the answer is (spoiler warning): 42.
@@LuisAldamiz No, we all know the answer is really 𝛑^(3ɸ)e^(-𝛑)ln(2). It involves all the numbers that appear everywhere
Two questions for you guys that have always confused me about antimatter. First how exactly do you get anti-neutrons? I mean take an electron and mush a positive charge into it and you get a positron and vice versa for the anti proton I can grasp but I don’t understand how you can get an anti version of something with no charge.
Second question is if you take an anti hydrogen atom and smash it into a larger atom of regular matter does the whole atom get consumed or just a single proton and electron? So let say you shoot a stream of anti hydrogen atom into a bar of lead would you eventually end up with a bar of Thallium (assuming you could only have each atom of the lead interact with a single anti hydrogen) or would you end up with nothing at all but a large quantity of energy?
I've seen enough star trek to know the word "positrons"
Just the word mind you🤗
The word positron long predates Star Trek. I believe that Isaac Asimov invented the word in his Robot series which he began to write in the late 1930s, early 1940s. His version of robots were controlled thru the use of “positronic” brains, manufactured by the fictional US Robotics. By the way, he also coined the word “robotics.” How’s that for having an impact on Science Fiction !!
Spok Haha - there should be at least a few others that know this stuff. As you know there are tons of Star Trek fans around, and there should be at least a few (elderly) Asimov fans left in the world. Thanks for writing. Live long and prosper !
I clicked on the new Dr Becky video as soon as it came up, but I couldn't watch it. With my hearing loss, the background music overwhelms the spoken words.
The antimatter version of Dr Becky hates Physics and loves Astrology
This is really good. It's way a documentary should be. Thanks Dr Becky.
Great Subject and what you were trying to convey. Bad.. Too loud background music and for some , distorted audio / phase problems covering the voices.
i might agree on music to a degree but phase? nah.. you might have your earbuds half plugged.
please point me to a problematic location.
No phasing issues in the audio stream (or video, for that matter) here.
That was great, I enjoyed every minute of it. Very well done.
good video but the music/sound effects are too loud, it's hard to hear you
I agree, it sounds super loud on my monitor speakers and spoiled the great video
One upvote for Star Trek, one upvote for on location reporting, one upvote for props, one upvote for awesome simulation graphics... I'm way over my upvote quota and I haven't even gotten to content.
We basically group matter and antimatter by "what exists around us" and "what only exists if we create it in a lab". But for particles from which we can only produce the particle _and_ its anti-particle in an accelerator, how do we define which one is the anti variant?
Why don't we group them by physical properties, like charge? Wouldn't it make sense to have protons and positrons in the same group? Is there any property that protons and electrons have in common, but positrons and anti-protons don't?
You could group them by charge if you wanted - they're called 'positive particles' and 'negative particles' instead of 'matter particles' and 'antimatter particles'. Whatever property you're interested in determines which property you'll group them by.
I'm pretty impressed with the engineers that listened to what the physicists said, then designed and built the machinery to run those experiments.
Space is big. If you think CERN is big, well that's just peanuts to space!
What a lovely job you have getting to visit CERN like that!
I'm not a physicist so maybe this is a dumb question. I have previously learned that anti-matter can be seen as normal matter going "backwards" in time. What happens if normal matter is "flipped" in another dimension (not time)? Would it turn into anti-matter?
Reinfallt I am a physicist and I asked the same question. It seems to keep on disappearing off this list of questions though. Glad that you’re seems to have stuck
I love this subject and also absolutely love the format you chose for to this video. Congrats and keep up the excellent work
It's somewhere...over there...riding the echo of a glare...wearing a frightful stare...bearing the timeless tear
Excellent job, absolutely loved this video.
Thanks Jacobus 👍

Stuck in my brain. Thanks for helping me to understand more!
Felt like I was watching Science Channel- Great job! Very cool you got to go to Cern- Thank you for taking us with you!
Better documentaries than many many many high-budget documentaries. Passion and talent rules!
That was one of the more interesting and thought provoking presentations regarding this matter. Thanks again for another great vid. 🙂
Loved this film Becky, you really make science interesting and fun! Thank you
sounded to me like a song of Fleetwood Mack.
Congratulations on the first 100.000 subscribers! So very well deserved
You are my go to physics educators !!! Still freaking out over the new age of everything ✌🇨🇦
Wonderful, thanks. The most professional video yet!! Are you and April from the same area, your accent is similar?
this is better than anything on Discovery Channel or History Channel since 2005.
As you were patting that bit of the detector (14:08), I couldn't help but compare it to one of your "patting the telescope" photos ... That detector is perhaps the largest Microscope on earth.
Great video!
Dr. Becky! What a great series! Thanks. I particularly liked this one. I worked at Brookhaven Nat Lab helping physicists with their 'maths problems' and computer programs used to 'detect events'. This program showed a picture of an event in the BNL Bubble Chamber. I met a friend through our work on the bubble chamber. Later he went on to work on the designs for the superconducting magnets at CERN. Several of his patents are used there. I did a little work at CERN, too, when they were having some problems calculating PI out to 100,000 decimal digits. Cheers. Thanks for the great work.
You so cute walking around CERN like kid in a candy store.You can always explain very difficult topics so anyone can understand it - thank you.
At the start of the video I was thinking 'yes I know about that part, but what about gravity?'. Now I know I have to be a little bit more patient :) Great video!
Congratulations on reaching 100 K subscribers. Stellar !
It's in the antimatter version of our universe, where there are people saying where is all the positive matter.
It will look negative from their perspective.
Perhaps we're the ones living in the negative world
Love this video 👍 just imagine how empty a region of space would have to be to find a good quantity of antimatter in the natural environment...
A year from now you'll be on all the late night TV shows explaining why antimatter is so cool. I hope this is what you want because you're an unstoppable force with a great gift for this (and painting fingernails).
I don't know anything about anti matter as I'm more of a BH enthusiast, but this video made me have an idea about it. Thanks for the interesting video, Dr. Becky.
love your videos and love your enthusiasm. Keep up the great work. Can't wait for the blooper reel.
Dr. Becky, another very well done content. Bloopers portion suggested addition to the dude at CERN. "If its not working...plug it in". Even though I know this axiom well and preach it, I'm embarrassed to say It still ends up 10th on the list even after my soft & hard resets.
Nicely done. I hope the BBC is paying attention!
I loved it Becky. New fresh form, fantastic job.
Thanks for the video. Dr Becky you are amazing and exited about what you show us it makes the videos so much better. Thanks again.
The background music makes it more soothing.
Very interesting. I have seen several videos about lhc but all were talking about the other detectors and higgs boson, first time I'm hearing about lhbc and antimatter.
This new format is great.
Thanks for your work and sharing.
Love&gratitude.
Thanks for taking us into CERN! Amazing things happening there, great to have an insider's glimpse. Your anti-gravity question reflects a question I have - are there, or is there a search (or even a need to search) for anti-bosons? I have not read anything about that yet.
Incredible how 2 different people have a lot of different things to offer about the same topic, both you and "Physics Girl" made a video about antimatter at CERN, yet, totally different stuff, and you can learn a lot from both, and that's exactly why I follow several physics channels...
Me and my daughters new favourite channel! Keep going dr Becky!!
8:05-10:26 I'm not sure if it's because I love learning cool science stuff or because I'm exceptionally gay, but I could sit and listen to this woman talk about particle physics for hours
I would never have thought that a banana could have something to do with anti-matter.
🤯
This is like monitoring a graduate studies class at Wossamotta U! Are there antimatter versions of Moose and Squirrel?
