One of the authors of this paper was my lecturer for plasma physics. He showed us the results towards the end of the lecture, around 3 hours before they were sent off to the journals :)
Did he mention what he believes is the cause for matter and antimatter imbalance in the universe?
@@_John_P No, that's not something he works on. Even if he did, I don't think he'd hypothesise in a lecture
@@xxX69420Xxx I'm sure if anyone had asked, he would have made a guess.
@@_John_PYou're sure of what someone else will do without evidence? That's a big assumption, brother.

I'd love to see some kind of collab between Astrum, PBS space time and SEA
yessssir
Don’t forget V-101 Space.
Buddy…. There is quite the chasm between PhD holders and researchers, and a couple dudes who “research” a topic by just reading some papers/articles and making a video for UA-cam money.
@@dillan6134 this is true but i think the intended meaning was to mix and match the video styles and narrators, and having all three collab would make for more grounded and better research no?
@@dillan6134there is a difference… but one of the most important physicists of the last 60 years was a plumber. Yup. Susskind was just some guy that read papers and explored his curiosity while clearing pipes of stagnant feces before becoming a doctor.
He had his feel of physics worked out while being a plumber. He only went to pursue his PhD in order to understand the language he needed to speak to explain what he naturally understood in his mind to others.
Sometimes the smartest people in the room are the ones others laugh at.
I don't pretend to understand half of what is said, but I really find your videos very interesting, I learn something new every time.
+1
Same as me. I think half my wonder is the subject and half is amazement that these guys know as much as they do.
Yeah man my high school English education doesn’t hold up to this
Don't worry too much about understanding everything right away. Just like any subject matter it takes time to learn it. All that matters is being interested and willing to learn. The rest will come with time. :)
I'm normally good at understanding this field of science but this one lost me a few times, always more to learn 😅
I had heard about this paper already in an interview, but I didn't really understand that the weak force was different until this video so thanks
I find all this extremely fascinating, even admitting that for many of my years I thought, "Antimatter was only something out of science fiction" I would love to hear a lot more on this subject
It still is for 99.9999% of us. lol. Maybe kids in the future might get some cool anti matter toys. That’s if toys can compete with going to see their friends on Mars… 😂
@@matthewyabsley Unfortunately, antimatter toys would catastrophically annihilate ordinary matter they touched.
@@JohnRandomness105 Yeah, even the smallest antimatter gun would do a lot more damage than modern hand-held rocket launchers. Give those to kids, and there would be a lot of dead people.
@@matthewyabsleyjust a spoon of anti matter reacting with matter would be 1200 times stronger than the bomb that was dropped on Hiroshima.
I haven't listened to even one second of the video (they're trying to fool the public into going along with funding an even bigger, more expensive and more useless particle accelerator). But I can say this is all a scam. Physics went completely off the rails with the Copenhagen interpretation and has accomplished nothing in at least 75 years. See Alexander Unzicker for more. I have many more sources but am not going to list them. But did you know they've studied electromagnetism for 200 years and still don't know how electricity works? Search "Jefimenko, electromagnetism, causality. Philosophers have known all along that physicists aren't doing science and have been writing unread books and papers about it all the time. Also read Freeman Dyson's Why Maxwell's Theory is so Hard to Understand. That will tell you why they have the flexibility to fabricate nonsense forever.
Remember when medical science wanted to outlaw breast feeding during the 60s and 70s and even into the 80s? Well, medicine isn't the only flimsy science.
From looking at this setup, it's clear that it isn't like an atomic interferometer. It's designed to capture antimatter to take measurements. However, this setup looks like it can be run with regular matter too with the tops and bottoms set up to measure regular matter to see if the error ranges are similar. If they are, it would point to the method of measurement ( the hardware setup itself ) being a primary source of the range and would suggest moving towards an improved method of measuring.
I suppose they have run this with regular matter to see if it then matches the outcome of their simulations.
The difficulty with using regular matter in this experiment, is detecting the collisions of a single hydrogen atom... because regular matter won't announce it's location with a burst of gamma rays from annihilatation.
@@juliavixen176 I know, hence me saying " with the tops and bottoms set up to measure regular matter ". It would have to be a different method of detection. What needs to stay the same is the orientation and directions of the hydrogen atoms being the same as the anti-matter chamber's experiment setup.
@@juliavixen176Some ideas are brighter than others...💡🧛😱💨🕳️🫣😎
@@juliavixen176 Doing this experiment with regular matter would actually be a lot easier, since you wouldn't have to worry about antimatter annihilating before it reaches either end. You'd need a simple particle detector (they have been around for more than a hundred years), and it would tell you when a hydrogen atom passes by.
Love that you covered the actual experiment setup
I feel I do understand these concepts the way you explain them. I appreciate it.
This result was interesting. If we consider that the most mass of the proton is from the gluons, then we know that mass from energy (E=m*c²) falls "down". Then if the quarks themself would fall "up" we would see less than 1 G of gravity for the anti-hydrogen. The difference would be tiny, so a more precise experiment is needed to resolve this.
Good point!
Gluons, quarks and nuetrinos likely don't exist. They were all invented to patch over holes in prior theories (hypotheses, really). They're not practicing the scientific method. They're inventing hypotheses to save prior hypotheses and so on.
Where did you get the idea of falling "up"?? Antimatter is absolutely no different to normal matter in its interaction with gravity. Astrum should stick to topic of astronomy, when it comes to quantum physics, his understanding is extremely inadequate , his "quantum eraser" video is one such example if misleading content, this video is another.
@@AG-ig8ufconsidering scientists from CERN are testing and continue to test this very point, it clearly was not taken for granted that antimatter responds the same to gravity as matter.
@@AG-ig8uffor a while we really weren't sure. There was some math saying it might but just because math allows it doesn't mean it's physically allowed
I love how that experiment was done, nice walk trough! :D
Yes, agreed, these deep subjects can be a bit hard to get a leg up & climb out of when the walk's over... :🤔D
Angela Collier went over this, highly recommend hearing her physicist's take on the experiment.
Thank you . Because of this video I learnt in a concise manner the differences between matter and anti-matter in terms of their interactions via the 4 major forces. I am actually even more puzzled that the weak force shows any difference at all and about why we still have no explanation for the baryonic asymmetry. This leds me to ask if we really think there is really an asymmetry or if there is some other explanation. Overall the clarity of the presentation and its allocation of time to each point discussed. Rather than delve too deep into controversial points or over explain and complex point the video does a good job or touching upon every key point letting the viewer decide on how to digest and process the information. I greatly appreciate this Video for in content and presentation.
Neat! That was a very thought provoking informative video! Thank you! 👍
Amazing world of antimatter. Please continue to post about this subject and maybe the eccentric Paul Dirac
Thanks for the hard work!! Keep it coming!
I genuinely enjoyed this video and would love to see more about antimatter!
Sweet. I would love to hear more discussion on this topic. Thanks for posting. God bless.
There are no gods
@@Rustyfin1958 I'm sure you have some...everybody does.
@@Rustyfin1958 True. There is only one.
Antimatter having antigravity would have implied an infinite amount of potential gravitational energy, which would make no sense at all. It's great to finally confirm this experimentally though!!!
how would it imply that exactly?
I like where you are headed but need more explanation. You made me think of this though, and I'm sorry to plagiarize if this was your point. If antimatter had antigravity, there would never have been the initial annihilation of just about all antimatter with the nearly equal, but slightly greater, amount of matter. The two types would have pushed apart and the universe would be different in the extreme.
Would antimatter be attracted to itself or would it repel matter as well as antimatter? If the former, where antimatter attracts antimatter but repels matter, and all antimatter survived by never coming into contact with matter, I would imagine an oil and water universe. All the structure of the universe times two. Entire galaxies of antimatter. But I guess more radioactive?
For the latter case, if antimatter repelled all forms of matter, then I can imagine we'd have our current universe, but with double the amount of visible stuff. But half that stuff would just be clouding space, which is not the case. But I suppose it would lead to acceleration of the expansion of the universe. But, there is just no antimatter to be found. We have to create it.
@@jkelly02 That is a popular theory, and a thought that I've had.
What I was getting at with the infinite antigravitational potential energy is matter and antimatter would repel each other forever. So pretty much the same idea as what you just said, except I want to calculate how much total repulsive energy that is. With normal gravity, the potential energy is mgh. So you'd think it would be for antigravity, although we shouldn't jump to conclusions. But if it was mgh, then wouldn't h be infinite since they're pushed apart forever?
Not really. V=+/-q1*q2/r has no infinite amount in any positive or negative gravity. Singularity only happens at r=0, but regardless of matter or antimatter.
@@hongdu6541 What ate the q's in this equation? Yeah I started to think about it and want 100% sure it was infinite, it's kind of however the calculus works out.
Beautiful diagrams + animations + models for describing something so complex
I didn't know about CERN's antimatter experiment so I'm glad you posted this. The imagery always helps me understand better because that's how my mind works. I am interested in any new experiments on the nature of gravity.
I hope that, no matter how technologically advanced we become, the universe never ceases to suprise us. My hope is that no matter how much we know, there's always going to be more to learn.
It seems that every time we pull back the curtain to learn something about the universe, there is 2 more unknown curtains that are under it. Kinda seems like the more we know, the more we don't know...
True, maybe one day we know everything about this universe, a completly new one emerges one way the other...
The universe is queerer than we can imagine

Wow I got to 2mins into this and I was just about to say goodbye as I thought I wouldn't be able to understand any of this but you have managed to capture my attention as you explain it so well. Thank you👍❤️🏴
Agreed! This is the sort of thing the pre-Internet generation didn't have. I was well into my 30's before I read an article on the Internet, and before I saw a video was a bit after that. Today's kids will grow up much more educated than we did - but possibly also much more mislead, defrauded, etc. Not everything is as scientifically accurate as this video - and I am assuming its accuracy because it does not set out to be especially persuasive. It presents the known facts. We decide to believe it or not.
I have a phd in astrophysics, some decades ago, but never realized that antimatter behaves differently under the weak force. So i learned something new at the fundamental level. Also, it never ceases to amaze me how clever and intricate the experiments are. So, a very nice, captivating and educational video thanks so much.
Alex is a very good educator. Great video!
This was wonderful, thank you! I've always wanted to know more about the matter-antimatter question, and I've learned things here about antimatter which I hadn't known. I would love to see more on this topic, cheers!

When you do, make sure you add them to your, "Do Not Recommend Channel" List. Otherwise they keep showing up in your feed. My feed is an absolute dumpster fire right now, as the algorithm seems to prioritize clicks over disseminators of factual information.
@@NorthernChev for me these nonsense channel don't often show up in my feed (where I can do-not-recommend them) but they do show up very often in searches and sometimes (= too often) in recommendations when I am watching another video.

outstanding presentation, Very accessible. Thank you.
I always learn something new and awesome from watching your videos!
Since gravity is not a force but a result of a curvature of the space, both matter and antimatter can be alike and not any different when subjected to gravity. It’s no surprise to me.
If you define gravity from an Einsteinian Relativity standpoint, yes. Which I do, as well. I'm guessing you had the same reaction I did when you saw his chart showing Gravity as a Force.
Gravity is as much a force as all the other fundamental forces in QFT
@@kapoioBCS Yes, even in general relativity it's the force that curves spacetime.
define force... i'll wait.
@@maeton-gaming A process of energy transferal.
Im hoping there is a mirror universe to ours made of antimatter where time runs backwards
It's my favourite explaination for the missing antimatter
Time not necessarily runs backwards in that mirror universe, that bit I'm not sure if should be included in the hypothesis. But I always thought that the reason we see antimatter quantities so small is that we are in a matter bubble and out of the observable universe is a similar antimatter bubble with the quantities inverted. I like to think the universe is just "a bubble in the sea" because that explains every inconsistency of quantities. Of course, there's no way of proving it as the theoretical border of the bubble would be out of our observable distance and farther away each day. So at best, can be considered a theoretical hypothesis but I still like the idea. 😁
Hope and dreams are still free after all. 😅
The sensational Reverse Brothers...
Time does not run. Stuff runs through time.
@@greggoog7559
True... Antimatter and Matter are still bound by time.
Since Time Travel isn't real.
The distance of antimatter travel may be more, less, or equal to normal matter. However, it's never in the reverse of time itself.
Let alone, the "original" matter as all Normal Matter has an equal opposite of Antimatter. But where that 50% antimatter half is? That's unknown.
So everything goes from disorderly to order?
i luv when the voice is a humans whos actually interested in what there talking about, you videos are really good for people with natural interest in subjects they may or not may know much about, this would be great homework for those who are ahead of the group.
i like hearing about this kind of stuff, looking forward to more.
I was pleased with the CERN anti matter v gravity result as I have a working hypothesis regarding the nature and functionality of gravity that predicts that gravity should affect anti matter and mater in the same way. So this result was a great boost for me. It has not failed a test yet.
Probably Sofon’s fault
I learnt a lot! Great video. Would love to hear more about it.
Very well presented!
Would appreciate to see more.
Other UA-camrs please take notice! This is how it should be done.
Antimatter drives have been one of my favourite solutions for powerful starship drives in Science Fiction, so I am interested in anything on antimatter. This episode of Astrum gave me real information that is as fascinating as fiction. Please more episodes and information on the topic.
Angela Collier did three videos on anti-matter, half of them are specifically about how to build an anti-matter drive.
UA-cam nukes comments with URLs in them, even if the link just points to another video right here on UA-cam. So you're going to need to just search for Angela Collier, because I can't link directly. She has a good video on a couple of ways that you can use anti-matter to propell a spaceship.
@@juliavixen176 Thanks very much. Here I go down a rabbit hole.
@@juliavixen176 Thanks again! Much appreciated.
@@juliavixen176sssssssssss
Does antimatter have antitime? Does it have antigravity? If it does have both then if studied it would appear to fall in gravity but would actually be rising but backwards in time. Perhaps the antimatter proposed to have been produced in roughly equal amounts to matter in the Big Bang went backwards in time thus never encountering matter and mutually destroying each other.
I've learned something new about anti-matter!
And...
I'd like to hear more on this topic.
Interesting video explained very clearly in my view thank you. Would love to hear more on this particular subject.
Love this channel and this video in particular. I really like that you include information about the actual experiments. I'd like to see more of that in my favorite UA-cam channels. Thanks
Note: gravity is explained by general relativity - not special relativity.
Most interesting talk. I was amazed by the way it was simplified. Fantastic
I was amazed to scroll several pages of comments without seeing anything about demons or portals.
Good job, astrum audience
I am not a scientist but something just came up in my little brain. Since we all learned that matter and energy can not be produced nor destroyed but can only switch from one form to another, is it plausible that the antimatter was not destroyed but somehow was transported into a parallel universe of antimatter?
"matter cannot be created or destroyed" is only really a "law" for chemistry, where you conserve atoms between reactions. The more fundamental law is that energy is neither created nor destroyed, only transformed. So a particle and anti-particle colliding destroys matter and releases energy as photons (usually).
Look around you. Look *around* you! Just look around you! There! Now, take a closer look. Have you worked out what we're looking for? Correct, the answer is "anti-matter".
Lol

Ty for this presentation!
It would be very, very difficult to determine if anti-matter had a negative gravitational charge. A lot of people suggest anti-matter would fall up, but that ignores what gravity is: A bend in space-time. Here in Earths gravity well, a "straight line" through space is curved down to the ground. What that means is that a particle that curves space outward, instead of inward, would still be completely overpowered by all the positive gravity on Earth. *Such a particle would still fall down.*
You'd need multiple anti-particles to see if they repel each other, and you'd need to do this in free fall (In zero G).
it would be more like, that antimatter would fall towards antimatter, so technically it would also have a positive gravity, but repelled by matter, which is its opposite. So you can actually have the same mass charge for both matter and antimatter, as they are attracted to themselves, are repulsed by their opposite.
@@dragnothlecoona Can you elaborate? Positive gravity creates massive gravity wells, while negative gravity would do the opposite: Create a gravity hill. In either case, the particle itself will move in a "straight line" to wherever space is more heavily bent, which on Earth would always be down as matter outnumbers anti-matter.
Putting that another way: A particle with negative gravity would still follow the World Lines of space-time. It can't escape a singularity, for instance, just because it has negative gravity, it *must* follow space-time curvatures made by positive gravity.
I don't understand why so many are claiming that a particle with negative gravity would suddenly accelerate away from a gravity well when Lorentz Transformations suggest such a thing is impossible? If you inverse the gravitational constant, you end up subtracting from total G when computing a force, but if there is more matter the net result is always an attraction.
And so surely a fist-sized clump of anti-matter would, if it did have reverse polarity gravity, aggressively push apart from each other as they bend space-time into a gravity hill, and end up flying into Earth because of it's much larger gravity well?
@@WestAirAviation Well your looking at it wrong, what I am saying to keep it simple, is that antimatter may simply be attracted to itself and repelled by matter, and that matter may be repelled by antimatter, and is attracted to itself. Infact if both matter and antimatter repelled each other with equal strength, then the whole expansion of the universe would make more sense as essentially it could be that all the antimatter and matter are pushing each other apart. This could also by why we don't see antimatter and matter collisions, because they are too far apart to cause collisions, or the amount they push away from each other is essentially double then that of matter falling towards matter. For something like a singularity, it is neither matter nor antimatter and has a positive mass charge, so it could be that both are attracted to singularities such as black holes. This would moreover better explain the spiral shape of galaxies and the more uniform speed that that both the inner parts and outer parts of the galaxy seem to move at relatively the same speed.
This is what really irks me about this coverage, Scishow spacetime did an episode on it that was much more satisfying. If you do the math there was never a reason to expect anything different, this is the equivalent of doing 2 + 2 = 4 - 2 = 2 and then freaking out because anti-matter was involved.
Edit, in response to your paragraph. The real issue with your mental model is that you're trying to treat relativity and quantum mechanics the same, they are fundamentally different even if you can draw comparisons that seem appropriate. It's important to remember any conjecture should be provable in theory, most of this science is done in math so when it's "translated" to a form understandable by the laymen it loses some of it's accuracy.
Gravity is a product of mass, anti-particles have inversed charges but not negative mass, that's an extremely important distinction. If negative mass did exist you'd see physics defying acceleration, but that's also implying you could form negative mass somehow which no theory of observation implies. Math wise none of it works or even sounds plausible, theoretically you're so far outside of what's logical the only proper response is "no" which I can understand isn't satisfying.
An interesting place to go from here might be the hypothesized correlation between dark energy and blackholes. I think it's especially peculiar what gravity and inflation have in common, inflation isn't considered a fundamental force but gravity is, and yet gravity is unique in that it's not even a force by definition. Both appear as mono-poll, single-charge, emergent properties of space-time itself.
That's a current topic of debate and kind of similar to your positive/negative gravity idea, just with theory, I hope it's of interest!
Love this channel. Some of the comments here make me amazed the person can even figure out how to use their phone, or the internet in general.
That's nota very nice thing to say about Alex McColgan, is it? He seems like a pretty clever chap to me...🤔
@@joerosen5464 the person leaving the comments, not the person making the video you dunce :)
I just cannot like this channel, there's clearly a lol of effort put in but it's all framed like a history channel documentary and I dislike the dramatization. Anti-matter didn't surprise anybody, we were checking our assumptions and they're right. People aren't learning a proper grasp of anything here they're getting buzzwords, the comments kind of support this.
@michaelEilers your comment made a lot of sense when I read @Blewlongmun comment 😂 hahaha
Might be a cool future video to show how the Tevatron, Main Injector & Recycler accelerators at Fermilab made, stored, focused, used and recovered antimatter protons (PBars) beams to conduct experiments.
I don’t know much about the FermiLab itself or there experimental work and as such I would love a deep dive. Great idea.
Many thanks for explaining this fascinating subject with simple analogies that the majority of people can understand. This will encourage a greater number to support this work and potentially join the scientific community.
at 17:01 is it supposed to be 1.6g like you said or 0.16g like it was written on the screen?
If you look at the error bars it is absolutely clear that he meant to say "0.16g".
This better fits the Theory of mass being an energy level rather than an individual particle used in the Standard Model as if magic tricks explained the disappearance of the electron and magical appearance of the muon.
"mass being an energy level"? What is that supposed to mean?
No, the Standard Model does not say that mass is an individual particle. What on Earth are you talking about?
What do you mean with "disappearance of the electron and magical appearance of the muon"? What on Earth are you talking about?
@@bjornfeuerbacher5514 "No, the Standard Model does not say that mass is an individual particle. What on Earth are you talking about?" - I guess it's a misunderstanding based on the often heard popular science claim "the Higgs particle gives the particles their mass".
You're confusing topics, but it is true that the Higgs Boson is a scalar field.

INTERESTING NOTE: When cancer patients go in for a "PET scan," they are leveraging the power of antimatter to help determine which cells are growing out of control so doctors can know where the cancer is progressing...and how fast. PET = Positron Emmission Tomography.
This use of antimatter technology is utterly fascinating to me. May such progress continue in the battle against cancer, that terrible disease that killed my beloved wife Sharon 5.5 years ago. Stay strong, all ye cancer patients and their caregivers!
I'm so sorry for your loss cancer is such appalling disease, it's so difficult to adjust to life after loosing someone so precious, it's not something you get over you just try to learn to live with the loss. I'm sure you have realised by now that grief is a very fickle process and it is far from linear. Try to live the life that Sharon would have wanted to to have and be kind to yourself and give yourself whatever time you need to process the loss, I hope you find some peace and I wish you the best for the future.
PRIOR to seeing this I had noticed that anti-matter decays at a different rate than matter (faster of course). What fascinates me here is how the weak force interacts and that the chirality (left or right handed spin) will determine whether or not there is an interaction.
Unless it's related to the CP violation discovered in the 1960s with kaons, this is the first I heard of the asymmetry of the weak interaction.
Same! This is something new to me.
Pretty sure that's what he's referencing, all these studies were trying to check was anti-matter and gravity, all they did was confirm the obvious.
I feel more intelligenter now.

We need anti oxygen to make anti water, imagine taking a sip and immediately bursting into light
What a BRILLIANT idea!😎🙈
You'd need anti stars for elements that heavy. Or, fusion reactors which focus on colliding and recapturing larger atoms from small ones. Science does not understand why, if gravity affects and is created by antimatter the same way as normal matter, why don't we see far more antimatter in the universe naturally, than we do, or are we simply MISSING it.
You'd also have a much larger issue trying to contain your anti water, then drink it, without something causing it to burst into light on it's own. Say, water in the air. Would annihilate on its own.
And destroying the city all around you the moment you touched the container (or the air for that matter) 😮
In the very early universe, just after the weak force separated from the unified force, it was stronger than it is today. The anti- matter is supposed to have annihilated asymmetrically at or about this time. Perhaps the observed difference in weak force response of anti-matter was more powerful then and tipped the scale in favor of matter.
I do hope there is a mirror universe where antimatter won out over matter, just so that we have balance in the (meta-)universe!
I'm not sure how we could even know that a distant galaxy isn't comprised completely of antimatter. Wouldn't it emit the exact same light?
@@JathTech because vacuum of space is not perfect and there would be an area between galaxies where vacuum with matter meets vacuum with antimatter. Annihilation would take place there, which would produce a glow. Since we don't see that glow, there are no antimatter galaxies. (This is not my answer but copied from a Quora answer. The guy who wrote it said it was a good question 😄👍.)
@@ronald3836What if there's more than one pair of universes? What if there's like, universeseses?🤪
@@joerosen5464 multiverses are a thing. Or maybe not.
it was touched on briefly in this video, but the strong nuclear force appearing to not care about chirality when it should gives rise to a theoretical particle called the axion, which is one of my favourite dark matter candidates! :)
I get the sense from all these attributes: charge, handedness, spinup, spindown that we are not talking about any actual structure but only about unembodied attributes that have values and perhaps behaviors associated with them. There is nothing really there, it's all just information. Yet as you step back it suddenly becomes stuff...which makes it seem more and more likely that what we think of as stuff is simply illusion or perhaps representations of computation. Fun to watch even though most of it flies over my head.
The field of physics is the most interesting field of study in my opinion. My degree is in Cell and Molecular Biology, but I wish I would’ve studied astrophysics instead, though I do appreciate my education that fueled my interest in microbiology and the human body’s relationship with the microscopic life forms and how they can either be beneficial or pathogenic and cause disease and illness. Antibiotic resistant bacteria and viruses are the main focus of my work, and I definitely enjoy the work, but astrophysics, astronomy, and even astrobiology is my favorite subject to study as a hobby…
if you call them positrons, then the antiparticle would need to be a negatron
Position is the 'antiparticle'
@@peanheadm7883you must be fun at parties. And the anti of an antiparticle is what? That's right, your original particle.
Sounds like there's more than meets the eye.
The structure of spacetime is a tetrahedrally coordinated expansion contraction oscillation between points in space and antispace. The momentum energy of the expansion phase on each side of this oscillation is condensed to form either matter or antimatter, depending upon which expansion phase is condensed. This also determines whether the charge is positive or negative.
Antimatter. Great topic. I would like more content related to this, yes. An exploration of what an antimatter universe might look like, given the different ways it behaves versus regular matter...
Be well
S.W.
I have often thought that the diversity of all atoms, molecules and substances are all composed of the 3 basic building blocks, which is mind blowing.
Water, fire, earth and air. I count four! 😄
@@ronald3836 don't forget metal
Kind of like the Father, the Son and the Holy Spirit created everything.
Spirit, actually
Lol
This is probably going to be the plot of Death Stranding 2.
The fascinating thing about our narrative regarding the beginning of the universe is that matter and anti matter annihilated each other until all that remained is the universe :) That implies the universe is not symmetrical and might in fact be anti symmetrical, whatever that means. Lowest entropy states probably.
There's an alternate universe made up of antimatter and they think we are the antimatter.
It's amazing what man figures out. Thanks for sharing.
The zoom out starting at 4:45 had me shaking my head and saying out loud "what the fuck is that!!?
Absolutely ludicrous. Space is too big man
Yep. We (humans) will likely never go outside the galaxy. May be the solar system…
That was just a zoom out of the night sky, lol
You should see animations involving zooming out of our galaxy cluster and supercluster and all that jazz until the observable universe is inside your screen.
@@bsanders1 just another challenge to beat
Eventually™.
Mind-breakingly huge
You need to go to a planetarium. I went to the Haydon in NYC as a kid and was blown away. And now with the James Webb it seems there is even more to it then we thought.
As they quoted on our text book in school in Scotland
“Physics is fun”
Interesting research which will go on to further our understanding of the world around us
Many thanks to those who endeavour in this field😁
I've always been a little bit disappointed that they didn't name anti-protons negatrons.
Damn Anti-matter is just like Zlatan
It's so sad to see a channel with such good production and content always resort to cheap click-baity titles/thumbnails. For comparison, a few weeks ago, the content creator Angela Collier uploaded a video with a similar title - but the thumbnail saying "Of course it falls down". Then this video from Astrum pops up, but with a "..doesn't play by our rules" caption.
Great episode I couldn't look away an learning about anti proton's and positive charged electrons is a subject I would love to know more about. please post a video on the standard model we have today
I'm excited to hear that the science is moving forwards on this topic. Personally I felt like it made sense for antimatter to gravitationally repel matter ever since learning about the asymmetry mystery. But it also brings a smile to my face hearing that the mystery continues.
I’m starting to suspect Alex is following topics by Matt O’Dowd at PBS Spacetime… 🤔 😂
CERN just published this paper, and it's the current hot news that everyone is reporting on.
I have a question: if anti matter is indistinguishable from regular matter, how do we know that distant galaxies are not made of anti matter but rather of regular matter?
If there were significant regions of antimatter out there, there would be gamma rays coming from the areas between them and regions of normal matter where the "cosmic rays" of subatomic particles interacted between them.
We can measure the type and frequency of radiation given off by these distant galaxies you are referring to...
@@NorthernChev ah okay, that makes sense. Thank you so much for explaining
I would like to hear more about experiments that reduce the error to determine is it 1G or something different
Yes. Somehow 0.75G isn't 1G; even if the uncertainty is ±0.13G & the uncertainty of the uncertainty adds another ±0.16G...
Watch this space!
Oh, & the outer one, too...🤔

Interesting, this is how I remember the park brake shoe adjuster on Aussie 30 and 40 series Camrys. Spin the LH adjuster down to tighten, and spin the RH adjuster up to tighten.
I use the frequency of left and right handed people in the world. More right handed people = spin up, less left handed people = spin down.
Somewhat click-baity title😑
Yeah all his videos are like that 🤷♀️
Thank you I’m not watch now - YT needs to bring back thumbs down
How so?
What video are you watching cause this is literally 20 minutes describing the latest results coming out of alpha lab at cern...
And clickbait AI image too… sad
No! First we experimentally proved that it doesn’t! Second we know that gravity does only have one kind of charge which is always positive (all these are super simplified btw)
And an ipotetical substance that "fall up" is called exotic matter not antimatter
😊😊😊@@luco9155
Inertial mass might not be positive but negative gravitational mass is impossible.
Also anti matter is mostly just oppisiyly charged and spins differently, gravity doesn't care much about those differences
Gravity isn't a force, it's a function of spacetime. Antigravity would require anti-spacetime, not just antimatter.
Quiet you, weeb.
Man o man some of this stuff is so top tier I have to be on the top of my day to digest it lol seriously good .
I was partial to the thought of anti matter repelling gravity however to to be aware is the most important thing here and is enough for now.
Nice summary, thanks.
I used to think the disparity between matter & antimatter was an issue, but I've since realised that the level of matter in the universe is just part of the initial conditions.
To put it another way, it just means the matter in the universe is eternal. It doesn't require explanation
Really glad your video was recommended. Subbed
Fascinating subject I would like to know more about week force and the neutrinos
Greatly explained 👍
Yes, would like to hear more on.
As opposed to *from* one...my feelings precisely.🧐
I always had this fantasy idea that the universe did not create a lopsided amount of matter to antimatter. but instead created two poles, one which emitted matter, and one that emitted antimatter. and split off into their respective space time areas.
A universe that looks almost exactly the same as ours, but one that you can never interact with or face annihilation.
As someone who doesn't understand physics: the question you suggested experimentation on antimatter seeks to answer is the disparate quantities of normal vs anti matter. But would this question not also be answered in where does matter/antimatter come from? Is it formed new in some way or is it all just particles crashing around against each other that forms different types of particles? Is matter within the universe finite?
