Other than being a scientist herself, I think that because she apparently knows what ticks you, but she is also respecting your lead, she is adding a delightful dimension to your podcasts that ur alter Nick character didn't have. As one of your observant reviewers said, "you as a physisict and her as a biologist are having a great chemistry together!" Keep on adding crazy great content about hard to explain physics topics that few event attempt to get near!
You are one hell of a teacher. Everyone would learn more if they had teachers as inspired and passionate about the subject as you. And your wife is a great addition to the video. Wishing you both well and until next time... 💜
Totally Nick and his wife are a good couple. He is a great teacher, and she is a complimentary personality with an inquisitive spirit. I have learned a lot from Nick's videos, like the one on tensors, because they are funny and passionate!
If the educator is good, fancy graphics and or animations are not required. Such a fantastic, informative and weirdly relaxing episode! Please do more like this every now and then!
There seems to be a rather unwelcome tendency in modern physics towards sort of mystification. This video wonderfully demystifies the dark matter thing. Great job!
I don't think that's a tendency in the actual science, so much as in trying to communicate what the science means to those outside the field. The predictions and behaviors produced at the leading edges of science, particularly anything that is particle physics or relativity adjacent, are so unintuitive that it's difficult to explain them without making it sound a little 'woo' somewhere down the chain. There's a reason that whole swaths of the scientists who work on these regularly tell grad students to "Just Do The Math, Don't Try To Figure Out What It 'Means' ".. that model/math works amazingly well but trying to fit it into any kind of picture that our human-scale brains can grapple with just doesn't really happen. How many videos are there just on this channel diving into how certain explanations of quantum or relativity phenomenon which are historically considered quite good give rise to critical misunderstandings of some aspect of what's Actually Going On?
@@jellorelic I get your point and that's why science teachers like Nick are important for their ability to simplify complex concepts so that people like myself can get a clue about what's going on in science. Cheers.
@@jellorelic another problem, is the voice of the mystifiers tend to drown out the people with legitimate information. It's just so much easier to take some half truths and make the rest up, that there are many more people who do this rather than the hard work.
This was a great idea for a video. Having a guest who is scientifically literate but doesn't have a really advanced physics degree is a great stand-in for what I expect the audience's level of understanding to be. This was really a lot of fun!
I like that Awkward M knows just enough about the subject to probably match most viewers. Like, she's not totally clueless about basic physics concepts, which would make these videos a drag. It's also really good that she sometimes takes things and rephrases them in simpler terms that are much easier to understand. TLDR: Make more of these videos! 😊
Thank you both for this video, it was really educational and at the same time very enioyable. I've said this before: For me personally, you have a talent when it comes to explaining these kinds of things. No other science channel comes close to this. If I remember correctly from an older video, I think you've been a teacher. I can only Imagine how great your classes must have been and how many young people you managed to inspire to become our future Nicks.
Amazing M's questions and reactions seemed considerably more... organic than what I'm used to from the clones. I really enjoyed this and such a great way to convey a clouded-up concept that is dark matter.
It also made me think this'd get into talk of symmetry experiments because whenever I hear someone talk about that, that's exactly how it sounds like :D
I know it's only what we see here..but I love your relationship. I love how passionate he is to teach you and us and how you're willing to listen and you're engaged. It's a win win.
It's a lot enjoyable to see this, I'll be honest to ya. Not to mention how well it's all comprehensible. I've actually watched every one of these kinda videos and it seems like all of these help in understanding what kind of problems the Physics community actually faces. All I'm asking you to do is keep doing these videos with your wife. She's awesome!
The input of Awkward M is indeed valuable. This is basically demonstrating what a teacher of mine used to say: Most of my colleagues start preparing a lesson with the question "How do I explain this to my wife?" And he claimed it was a pretty good start.
I feel your wife’s frustration and curiosity at a deep level. I would be asking the same question as well! This is a very well done format that I think you should regularly post. It’s such a 1-1 conversation type education that is hard to get anywhere. It’s both fun, educational, and entertaining. Teachers have bad tendency of over simplyfing or over complicating theories- and you somehow found the perfect middle ground by having someone (your wife) be the middle man(woman?). I hope to see more of this!
A) Love this format. It really does help to collect what you've taught in other videos and summarize it in a digestible way. B) Seriously; relationship goals. You guys are awesome.
This really is just about one of the best science channels on UA-cam. Well done you two. I'd love to see Nick do one of the Royal Institution Christmas Lectures over here in the UK - he'd be brilliant at engaging the audience.
THANK YOU for this session. This was most informative overview of Dark Matter. The parts about massless matter, stuff being non-electro magnetic; spin determines interaction with weak force; really got my attention.
If I had any friends, the first and probably the only channel I would recommend. So worth watching and happy to find someone who speaks my language. Love you Nick ❤️
"Different is such a polite word for it". The other word is one of our favorites here: "A little crazy". And yes, Dark matter is only a little crazy. Quantum mechanics has some really crazy corners.
I really like these interviews because I'm a biologist but I've also been getting really into physics in the last several years, so I feel each side of the interview.
I am so grateful I came across your channel on my first day of vacation. I have allot to catch up on and so much to share with my kids. I love hearing others nerd out about things they are legitimately interested in. It's contagious!
Nick, you're always so much better at naming things than other physicists. Like it is so obvious that it should be called invisible matter and not dark matter.
Thanks! Although, we shouldn't hate on physicists for _all_ the names. Many of the names were popularized by journalists. Some were even popularized by _detractors._
One intuition of mass for me is like, "a measure of resistance of an object to acceleration by an external force" and another intuition is "the thing what causes gravity to move objects closer together" and yet another is "it's energy, but the kind that specifically distorts spacetime" and it gets hard to reconcile these sometimes.
Especially for our chimp brains hahaha oh man the more we learn the more we know that we don't know! It's great though, the thirst for knowledge can't be quenched so we'll always have something to enjoy!
The way you explain a lot of things makes it so much easier to understand. I've always loved the passion behind it too. Your wife explains it all perfectly at around 14:30 lol.
I find it amazing that the species has managed to come so far in its understanding of the fabric of the universe in such a short time. The difficulty in understanding is due to our normal perception of things on the large scale - how things actually are on the nano scale feels so strange and alien by comparison.
Yeah, that's why I firmly believe we know just about nothing considering how we're such a small piece of the universe. It's like if you think about how the world looks to a microbe compared to how we see it and you can begin to imagine the potential differences between the scale we see and the actual scale of the universe. Not only that, but we're terrestrial beings. We evolved to survive this planet and probably don't even have the ability to perceive many fundamental aspects of the universe. For this example you can think of how deep sea fish generally evolve without eyes because their environment doesn't call for them. There's a whole visual spectrum that they can't even begin to imagine. Even our current senses are limited. Mantis Shrimp can see millions upon millions of colors we've never seen. Our attempt at full understanding is admirable but most likely never going to happen.
Nick's explanation and communication skills are well renowned but I wanted to give kudos to Awkward M. She is a very, very good student, almost immediately grasping all the necessary basic concepts and reiterating them in her own words to check the understanding. I don't think she got a single thing wrong, it's a good content because she offers an alternative take on the ideas... and she absolutely nailed it when described standard model ZOO, that it's basically few symmetries and you get a new particle by doing some kind of flip but they are spiced up by broken symmetries. That was funny as hell. Her comprehension skills are admirable.
The elusiveness of most of the universe is mind-blowing. My brain is loosening it’s grasp on the ungraspable every day. Obviously, things that we can grasp don’t really matter. Funny how grasping things makes us feel secure.
That's the reason I click on stuff I (assumed I) alread knew. All your videos are awesome but this format in particular might just hit the jackpot. Honest: you made it confortable and cool for everybody. MACHOSs and WIMPs checked! (And that wasn't even the weirdest thing you said) BTW, the 99% of the Proton mass being made by masless things just humbles me down a lil' bit ;) Well done you guys!!!
Started this thinking will watch half now and the other half at night. Never knew when it got over. Great video as always, thanks for making this amazing content!
I was like: - Hmm... a longer video from Nick. Okay, let's jump into it. Some time later, watching the video - Does he mention the sponsore halfway of the video?... [checking the progress bar] WHAT?!? All 17 minutes passed?! :-O I didn't felt time passing this fast since high school where I had some good teachers who was teaching interestingly and made it joyable. Thank you for being this good teacher!
Hearing Emily talk about how overwhelmed she felt by all the information and contrasting it with my own reaction (just review of stuff I'd already heard several times) reminds me of how some students feel when I'm tutoring them in algebra and I'm moving too fast. I have to remember that the stuff that seems really simple and intuitive to me is new to them and they need time absorb it and let it sink in. It can be so easy to get comfortable in out knowledge and forget that we once struggled to understand things that seem obvious now, but being a teacher means you have to remember that experience of the information being new and overwhelming and stuff not all making sense. I think most of us have had a teacher who clearly doesn't remember that experience because they expect everyone to understand everything right away and won't make allowances for those who are clearly trying but struggling. It's easy to see that Nick remembers though, because he's always anticipating potential questions people will ask and preemptively answering them.
That's why, when people ask me for good introductory material (in some area of programming, that's my field), I usually pass - I typically taught myself based on an already fairly high level of understanding related topics, I have no clue what good introductory material would be! (But at least I know I have no clue. And I'm not a teacher.)
Wonderful. May I say the interaction brings the information down to earth. Love you two. Love the kowledge and the way you do itl. Thank you. Raphael NYC
7:05 is a really interesting question! Mind you I am still trying to get used to Dark Matter not clumping like you just said. Quite a delightful video, power packed with clear explanation :-)
I’m pretty sure that the *Dark Matter* particles also use *Surfshark* . That masks their location. Hence: We can’t detect them. How do you like this explanation?
Seriously, u r on 2 sth here, Chris!! I saw u made Nick laugh, too! So, along the lines of your comment, I'm wondering whether the String Theories - better yet, hypotheses - have anything to say about dark matter. I'm wondering whether dark matter is escaping our detection because she is hidden in some of those extra dimensions the Stringers hypothesize!
Awesome video. Love this format. I think my favorite line re neutrinos passing through your body is “That's Invasive” LOL. Can't help but wonder if I might be one of the commenters you are referring to when you say “You know who you are” :)
@@ScienceAsylum Thanks, but you didn't need to check. I was just kidding. However I easily could have been as I like reading about alternate gravity theories. I thought what you said was funny. Again awesome video. I never knew about the whole spin vs interaction with the weak force thing. Always learn lots from your videos. And you two make a great team!
Ok.... After intently watching this video, I decided that I will think of dark matter as neutrinos. It is the only way that I won't obsess about dark matter at night instead of sleeping.
I really like these videos with you explaining things to your wife. Although your normal videos are awesome and I find them to be the best way for me to learn advance concepts as I am dyslexic, these provide another ‘way’ to get things to make sense. Keep up the awesome work! =]
With the miniature i was afraid of what i will discover in this video, but yeah they knew what they were talking about and they are great pedagog!! Thanks you for your hard work
Y’all are both two nerds lol. And I love that y’all get along so well. Maybe there is someone for everyone, so I’ll keep hanging around and waiting to attract mine. I love it though that she is a biologist and you’re a physicist, and y’all get along so well. I guess I’m saying that there is a lot of respect between both of you.
Powerful video, you have increased my understanding of dark or invisible matter. Please keep making videos on standard model and even on Gravity which is not in standard model.
I love learning about Dark Matter and this time you trying to explain it to your wife was so funny plus you guys make a great team! I would love to see more content like this! :3
Great video! Short enough to tempt me to watch it - but plenty of (relatively!) in depth content. For instance, that comment about "containment" problems for DM, given the absence of electromagnetic force interaction, was new to me... and quirky enough to make it very memorable😊. Super presentation 👍.
In engineering they'll throw the Stress-Energy Tensor at you at some point. Add a time dimension to that thing and you're basically doing General Relativity, where the mass is made up and the coordinates don't matter.
Love this conversation format of explainers, thanks to M for taking the role of listeners like us starting from the videos on interpretations of QM! I bet Nick also enjoys having these back and forth exchanges :) Hoping to see more of this.
I'm loving this format Nick, you're so incredibly smart and fantastic at explaining this stuff, and your wife is fantastic at question asking to help the understanding. Def need more of this.
Great video! I really like all of your videos. I have one question though: why is there almost no invisible matter in our vicinity, and a lot in the outskirts of the galaxies? Cheers!
WIMPs are expected to be pretty uniformly distributed throughout a galaxy. It's just that a solar system isn't very big comparatively, so that volume wouldn't have much in it.
Watching you guys collab always makes my mind wander to Jim Al-Khalili and Quantum Biology. Probably because I’m trying to process everything you’re talking about. Either way, I love any talk about neutrinos because I have a hard time understanding exactly where they fit into our reality.
You forgot talking about 'Axion (imaginary)' in this talk. Nonetheless, it is a very summarising, all in one video for curious beginners. Respect to both of you for providing us this very abridged version of 'Dark Matter and it's potential candidates' video with quality edutainment as a bonus in it. Thank You. [DiowE]
I didn't forget about it. We actually talked about it, but I cut it because it was too confusing. This 17 minute conversation was actually a _75_ minute conversation. Axions should be their own video.
@@ScienceAsylum Understood, Mr. Nick. My bad, that i didn't think this far, that the video is an edited version & a 'Veteran' physicist cannot forget 'Axion' when he is talking on 'Dark Matter'. By the way, i assume that you will post that whole 75 minutes conversation on your other 'personal' channel. Right? I will check out that video later. Thanks again. [DiowE]
Grate episode! At first I was sceptic in this format with questions and answers, but it turns great! Tempo is a little bit slower than usual, but facts stay longer in memory, it is my impression. Emily and you are so qute together! Five stars!
5:49 Hang on. That just means it can't clump around itself. Since it is affected by gravity, it should still be able to clump around ordinary matter. So shouldn't we expect to find it around massive dense objects like neutron stars and black holes? And double hang on. Dark matter might not interact electromagnetically, but it's still fermionic matter. Which means once we have enough of it to be bound gravitationally, it can't collapse to a point. The Fermi repulsion should give it structure.
Neutrinos are fermions, but we don't have any evidence that suggests dark matter _must_ be fermionic. There are proposals for bosonic dark matter. I just didn't cover them in this video because they're outside the standard model.
@@ScienceAsylum can you explain a little bit better why dark matter can't clump in asteroids, planets, whatevs? I find it logic (somehow) but I'm not grasping the reasons behind it
@@ScienceAsylum Ah okay. That changes things considerably. Still, I don't think they could be bosonic. Aren't bosons mostly massless? And the ones that do have mass are unstable and don't exist freely in the universe. Although, I suppose that would fulfil the non-self-interacting property of dark matter. If it were bosons, they'd just pass right through each other without interacting.
@@davidcroft95 my understanding was because it didn't lose energy from interactions, so it would just keep moving, I imagine it would be kind of like how we use planets to slingshot spacecraft, it doesn't lose momentum only changes direction from gravity, which is why it becomes so diffuse, gravity on small scales is just too weak. I think it might make more sense to think of it as frictionless? At least that's my impression, friction is born from electromagnetism right? So without it, no friction? Think about how far a hockey puck hit fast goes on ice(low friction) vs like, concrete or something. Idk, that's just how I'm thinking of it.
By her questions, and the apparent unfamiliarity with the subject, I suspect Nick's wife normally doesn't either. It's a rare exception she made, for the sake of Nick's video... she probably lost a bet or something :-D
Still though, my wife knows I'm obsessed with understanding what I can about the universe, she could care less and is more into what activities she can do with our children. She didn't even want to see the aurora lights with me
5:20 And as on cue, I find this video (that had somehow escaped me), and here's the explanation/info I should've come across before asking my other question earlier today :) You're a great science educator, sir.
It's what we theorized to make our models work for the formation of galaxies. I truly believe that there is something else out there that is on such a large scale (larger than the universe) that it is impossible to theorize and comprehend. The size of the universe is virtually impossible to even grasp, let alone something even larger than that.
@@ScienceAsylum ... Not as much as biology. Big bang, red giant, neutron star, black hole, quasar (quasi-star), pulsar (pulsing-star), supernova, and even dark matter are names that work pretty well as reasonably accurate short descriptions. Compare that with ribosome, deoxyribonucleic, meiosis, stamen or estradiol, and I'd say, comparatively, we are doing pretty well in the Physics department.
@@ratamacue0320 Unfortunately that's not really good reasoning. Perfect black body doesn't reflect light but it can be very visible... The important difference is that it doesn't block light either. Dark matter most probably should really be called transparent matter.
“Back up neutrino I did not consent to this” haha love it. Really digging this format, Nick knows so much and Emily asked great questions :)
Yeah I hope they get lots of audience engagement however perceived including obviously lots and lots of views-wild that she is no longer teaching or a student as she has always been since probably single digit ages this Northern Hemisphere Fall(she shared on the lesser known Nick Lucid self titled channel)-I wish I was her maybe or something haha wow exciting that he is getting various stuff written for him by lots of contributors he has said but this is different clearly-I haven’t taught since Covid started to be clear early last year in the USA🤯🤯🤯🤯🤯🤖🎬🗽🌈✔️♾☮️💟🌌😻😍😘🥰😎

Not only that, but we're terrestrial beings. We evolved to survive this planet and probably don't even have the ability to perceive many fundamental aspects of the universe. For this example you can think of how deep sea fish generally evolve without eyes because their environment doesn't call for them. There's a whole visual spectrum that they can't even begin to imagine. Even our current senses are limited. Mantis Shrimp can see millions upon millions of colors we've never seen.
Our attempt at full understanding is admirable but most likely never going to happen.
And we did it with the same caveman brains that couldn’t figure out how to make a fire or a wheel or language for hundreds of thousands of years lol
Glad you're back
Nick's explanation and communication skills are well renowned but I wanted to give kudos to Awkward M. She is a very, very good student, almost immediately grasping all the necessary basic concepts and reiterating them in her own words to check the understanding. I don't think she got a single thing wrong, it's a good content because she offers an alternative take on the ideas... and she absolutely nailed it when described standard model ZOO, that it's basically few symmetries and you get a new particle by doing some kind of flip but they are spiced up by broken symmetries. That was funny as hell. Her comprehension skills are admirable.
The elusiveness of most of the universe is mind-blowing. My brain is loosening it’s grasp on the ungraspable every day. Obviously, things that we can grasp don’t really matter. Funny how grasping things makes us feel secure.
Excellent conversation. Definitely did the format and flow.
This channel has explained and entertained better than any class I ever took. Also, it’s instilled a curiosity to learn even more!
What i like about this is that it takes me slowley because of the explanation process,
Great interaction and easy to digest information. Great Video.
Greatest video on this subject. That was very fun to watch, I love this format!
That's the reason I click on stuff I (assumed I) alread knew. All your videos are awesome but this format in particular might just hit the jackpot. Honest: you made it confortable and cool for everybody. MACHOSs and WIMPs checked! (And that wasn't even the weirdest thing you said) BTW, the 99% of the Proton mass being made by masless things just humbles me down a lil' bit ;) Well done you guys!!!
That was a fantastic explanation! I think that is the first time that I legitimately grasped what dark matter is (or could be) and how it worked.
Glad I could help 🤓
I'm loving the acronyms xD This video taught me some pretty darn cool stuff, keep up the good work!
Started this thinking will watch half now and the other half at night. Never knew when it got over.
Great video as always, thanks for making this amazing content!
I was like:
- Hmm... a longer video from Nick. Okay, let's jump into it.
Some time later, watching the video
- Does he mention the sponsore halfway of the video?... [checking the progress bar] WHAT?!? All 17 minutes passed?! :-O
I didn't felt time passing this fast since high school where I had some good teachers who was teaching interestingly and made it joyable.
Thank you for being this good teacher!
That's great to hear 🤓
Hearing Emily talk about how overwhelmed she felt by all the information and contrasting it with my own reaction (just review of stuff I'd already heard several times) reminds me of how some students feel when I'm tutoring them in algebra and I'm moving too fast. I have to remember that the stuff that seems really simple and intuitive to me is new to them and they need time absorb it and let it sink in. It can be so easy to get comfortable in out knowledge and forget that we once struggled to understand things that seem obvious now, but being a teacher means you have to remember that experience of the information being new and overwhelming and stuff not all making sense. I think most of us have had a teacher who clearly doesn't remember that experience because they expect everyone to understand everything right away and won't make allowances for those who are clearly trying but struggling.
It's easy to see that Nick remembers though, because he's always anticipating potential questions people will ask and preemptively answering them.
That's why, when people ask me for good introductory material (in some area of programming, that's my field), I usually pass - I typically taught myself based on an already fairly high level of understanding related topics, I have no clue what good introductory material would be! (But at least I know I have no clue. And I'm not a teacher.)
True story.
Wonderful. May I say the interaction brings the information down to earth. Love you two. Love the kowledge and the way you do itl. Thank you. Raphael NYC
7:05 is a really interesting question! Mind you I am still trying to get used to Dark Matter not clumping like you just said. Quite a delightful video, power packed with clear explanation :-)
THank you for this episode, Professor. It was heartwarming!
Great video, very entertaining and informative
Thank you for making these videos
You're welcome. Thanks for watching 🙂
really enjoy the interaction and hearing the conversation in real time. Great Job to BOTH of You !!!!
🌟🌟🌟🌟🌟
This was wonderful. Awkward M filled in for all of us!
The look M gives at 12:25 is all of us.
She did indeed.
I think this has been my favorite of your videos so far
I’m pretty sure that the *Dark Matter* particles also use *Surfshark* . That masks their location. Hence: We can’t detect them.
How do you like this explanation?
😂😂
Seriously, u r on 2 sth here, Chris!! I saw u made Nick laugh, too! So, along the lines of your comment, I'm wondering whether the String Theories - better yet, hypotheses - have anything to say about dark matter. I'm wondering whether dark matter is escaping our detection because she is hidden in some of those extra dimensions the Stringers hypothesize!
My brain is sizzling!
I do wonder however how much editing and cutting was done to produce this.
Thanks guys, wonderful as always.
The raw footage is 75 minutes long, so quite a bit of editing.
Hey! The upcoming Vera Rubin Observatory might just answer the mystery she discovered and named!
Awesome video. Love this format. I think my favorite line re neutrinos passing through your body is “That's Invasive” LOL. Can't help but wonder if I might be one of the commenters you are referring to when you say “You know who you are” :)
I was specifically referring to everyone bringing up modified gravity on my last dark matter video. Just checked and you were not one of them.
@@ScienceAsylum Thanks, but you didn't need to check. I was just kidding. However I easily could have been as I like reading about alternate gravity theories. I thought what you said was funny. Again awesome video. I never knew about the whole spin vs interaction with the weak force thing. Always learn lots from your videos. And you two make a great team!
Ok.... After intently watching this video, I decided that I will think of dark matter as neutrinos. It is the only way that I won't obsess about dark matter at night instead of sleeping.
I love this format, keep it going, really enjoyable to watch
"What do you know about dark matter?"
Oh! Isn't that the villain from Kirby's Dream Land 2? He shows up in a few other games too.
It is also an awesome sci fi action series, just for the record (which has nothing to do with Dark Matter BTW)
This video could have gone on for hours and Id watch it, Nick is a great teacher.
I applaude. This is hands down one of the best videos I've watched on this channel and that is not a light compliment. Also, we now want a wife clone!
She is a Biologist indeed. Careful what you wish for! lol
Loved it! You two are perfect together. More of these types of videos please.
I really like these videos with you explaining things to your wife. Although your normal videos are awesome and I find them to be the best way for me to learn advance concepts as I am dyslexic, these provide another ‘way’ to get things to make sense. Keep up the awesome work! =]
With the miniature i was afraid of what i will discover in this video, but yeah they knew what they were talking about and they are great pedagog!! Thanks you for your hard work
Y’all are both two nerds lol. And I love that y’all get along so well. Maybe there is someone for everyone, so I’ll keep hanging around and waiting to attract mine. I love it though that she is a biologist and you’re a physicist, and y’all get along so well. I guess I’m saying that there is a lot of respect between both of you.
Powerful video, you have increased my understanding of dark or invisible matter. Please keep making videos on standard model and even on Gravity which is not in standard model.
Your wife is extremelly nice and help us vocalize our questions!
Thank you Emily for asking the questions I had as well as the ones I hadn't thought of
I love learning about Dark Matter and this time you trying to explain it to your wife was so funny plus you guys make a great team! I would love to see more content like this! :3
Great video! Short enough to tempt me to watch it - but plenty of (relatively!) in depth content. For instance, that comment about "containment" problems for DM, given the absence of electromagnetic force interaction, was new to me... and quirky enough to make it very memorable😊. Super presentation 👍.
This discussion just reinforced my decision to go into engineering. "99% of its mass is made up of massless particles."
In engineering they'll throw the Stress-Energy Tensor at you at some point. Add a time dimension to that thing and you're basically doing General Relativity, where the mass is made up and the coordinates don't matter.
You usually make really good videos! But this was... also really good! Thank to both of you!
Love this conversation format of explainers, thanks to M for taking the role of listeners like us starting from the videos on interpretations of QM! I bet Nick also enjoys having these back and forth exchanges :) Hoping to see more of this.
It helps me gauge what I need to focus more time on, which is extremely helpful with weird topics like this.
This is a great format style!! Keep em coming!
Great chemistry
Props for the PBS Spacetime T.
A simple yet amazing explanation of dark matter. Thank you for this video.
I'm loving this format Nick, you're so incredibly smart and fantastic at explaining this stuff, and your wife is fantastic at question asking to help the understanding. Def need more of this.
We are surely but slowly going to comic book world lol
I LOVE your synergy together.
Great video! I really like all of your videos. I have one question though: why is there almost no invisible matter in our vicinity, and a lot in the outskirts of the galaxies? Cheers!
I'm really curious to get an answer to this if there is any
WIMPs are expected to be pretty uniformly distributed throughout a galaxy. It's just that a solar system isn't very big comparatively, so that volume wouldn't have much in it.
Watching you guys collab always makes my mind wander to Jim Al-Khalili and Quantum Biology. Probably because I’m trying to process everything you’re talking about. Either way, I love any talk about neutrinos because I have a hard time understanding exactly where they fit into our reality.
You forgot talking about 'Axion (imaginary)' in this talk. Nonetheless, it is a very summarising, all in one video for curious beginners. Respect to both of you for providing us this very abridged version of 'Dark Matter and it's potential candidates' video with quality edutainment as a bonus in it. Thank You. [DiowE]
I didn't forget about it. We actually talked about it, but I cut it because it was too confusing. This 17 minute conversation was actually a _75_ minute conversation. Axions should be their own video.
@@ScienceAsylum Understood, Mr. Nick. My bad, that i didn't think this far, that the video is an edited version & a 'Veteran' physicist cannot forget 'Axion' when he is talking on 'Dark Matter'. By the way, i assume that you will post that whole 75 minutes conversation on your other 'personal' channel. Right? I will check out that video later. Thanks again. [DiowE]
@@DiowE The fact that you didn't think that it might be edited is actually a compliment to my editing 😉
Maybe a less edited-down version on your other channel? I'm sure we'll like the more rambly bits as well...
Grate episode! At first I was sceptic in this format with questions and answers, but it turns great! Tempo is a little bit slower than usual, but facts stay longer in memory, it is my impression. Emily and you are so qute together! Five stars!
When a Biologist teams up with a Physicist, You get an educational and fun content!
This is a really cool way to teach! I love the format, please do more :)
5:49 Hang on. That just means it can't clump around itself. Since it is affected by gravity, it should still be able to clump around ordinary matter. So shouldn't we expect to find it around massive dense objects like neutron stars and black holes?
And double hang on. Dark matter might not interact electromagnetically, but it's still fermionic matter. Which means once we have enough of it to be bound gravitationally, it can't collapse to a point. The Fermi repulsion should give it structure.
I was wondering this too, but how do we know it's fermionic matter and not made of bosons?
Neutrinos are fermions, but we don't have any evidence that suggests dark matter _must_ be fermionic. There are proposals for bosonic dark matter. I just didn't cover them in this video because they're outside the standard model.
@@ScienceAsylum can you explain a little bit better why dark matter can't clump in asteroids, planets, whatevs?
I find it logic (somehow) but I'm not grasping the reasons behind it
@@ScienceAsylum Ah okay. That changes things considerably. Still, I don't think they could be bosonic. Aren't bosons mostly massless? And the ones that do have mass are unstable and don't exist freely in the universe. Although, I suppose that would fulfil the non-self-interacting property of dark matter. If it were bosons, they'd just pass right through each other without interacting.
@@davidcroft95 my understanding was because it didn't lose energy from interactions, so it would just keep moving, I imagine it would be kind of like how we use planets to slingshot spacecraft, it doesn't lose momentum only changes direction from gravity, which is why it becomes so diffuse, gravity on small scales is just too weak.
I think it might make more sense to think of it as frictionless? At least that's my impression, friction is born from electromagnetism right? So without it, no friction? Think about how far a hockey puck hit fast goes on ice(low friction) vs like, concrete or something.
Idk, that's just how I'm thinking of it.
Thanks, this made a lot of things more clear for me. Great questions and answers and great vibe :)
I asume 99.999999999999999 of all viewers are thinking "why is my wife/girlfriend not speaking about stuff I love with me like her"
By her questions, and the apparent unfamiliarity with the subject, I suspect Nick's wife normally doesn't either. It's a rare exception she made, for the sake of Nick's video... she probably lost a bet or something :-D
Still though, my wife knows I'm obsessed with understanding what I can about the universe, she could care less and is more into what activities she can do with our children. She didn't even want to see the aurora lights with me
I've watched your other video about dark matter two, the one you released two months ago, and I found this better.
Here are my two personalities when I am learning physics: the teacher who makes the student think and the student who makes the teacher think.
Both are great, I hope more teachers make the students think, and aren't afraid of letting their students make them think.
Outstanding Q and A. It got me to asking even more questions. You and your wife make a wonderful team.
Nick and Emily are quantum entangled souls- In this universe there is a special person for every person
5:20 And as on cue, I find this video (that had somehow escaped me), and here's the explanation/info I should've come across before asking my other question earlier today :)
You're a great science educator, sir.
This matter has been bugging me for quite some time: why is it called dark if it's invisible? Thanks for saying it as it is :)
Physics is full of terrible names.
It's what we theorized to make our models work for the formation of galaxies. I truly believe that there is something else out there that is on such a large scale (larger than the universe) that it is impossible to theorize and comprehend. The size of the universe is virtually impossible to even grasp, let alone something even larger than that.
@@ScienceAsylum ... Not as much as biology. Big bang, red giant, neutron star, black hole, quasar (quasi-star), pulsar (pulsing-star), supernova, and even dark matter are names that work pretty well as reasonably accurate short descriptions. Compare that with ribosome, deoxyribonucleic, meiosis, stamen or estradiol, and I'd say, comparatively, we are doing pretty well in the Physics department.
Because it doesn't reflect any light, so you can't see it.
@@ratamacue0320 Unfortunately that's not really good reasoning. Perfect black body doesn't reflect light but it can be very visible... The important difference is that it doesn't block light either. Dark matter most probably should really be called transparent matter.
