Paradox: The Nine Greatest Enigmas in Physics - Jim Al-Khalili
astronomy.nmsu.edu/nicole/teac...
en.wikipedia.org/wiki/Olbers%...
• Olbers' Paradox - A Le... - Наука та технологія
Did you understand the video? I want to make sure no one is left behind, and improve my writing and explaining where I can.
Yes the video was just perfect,those animations were just at the cutting edge!
Olber's Paradox is one of my favorites. I watched another video many, many years ago on the topic and I use its ideas routinely to bait hard-headed young-earth creationists into a science discussion that leads to them accepting that the Big Bang(or one of them anyway) happened billions of years ago.
"I want to make sure no one is left behind"
> "It's a little too late for that, don't you think?" - Star at the outer edge of our visible universe.
I certainly feel it is lots of ideas for 10ish minutes which isn’t wrong obviously but Smarter Everyday in particular talks about how this is challenging for UA-cam algorithms or whatever as I think I tweeted you... also, as I mentioned for instance on the latest Tibees I have a very unusual mind AND definitely science/math/tech UA-camrs however defined certainly do too I’d argue - one aspect outside of purely technical content is that it is fairly dark/night like of an episode which is appropriate but perhaps overwhelming to many viewers however perceived!? - maybe also even more panning across various skyscapes etc would be drawing viewers in and along with you and the comprehension gaps they may have encouraging them to watch again as happened for instance for myself when I watched this Cool Worlds episode over a year after I first watched it ( m.ua-cam.com/video/b_TkFhj9mgk/v-deo.html ) and was able to connect it in my comprehension (as I wrote about in the comments shortly after you uploaded this to UA-cam) in a weird way to this latest offering from you - the goal of Cool Worlds is raising awareness of a laboratory that does exomoon and similar research whereas a more general UA-camr probably is shooting for not necessarily a smash hit very occasionally but more steady interest and learning and so on however perceived... also I’m curious about the rights issues I guess it was fair use the film clips in that Cool Worlds episode and yeah obviously Tom Scott knows the latest hahaha - anyway I certainly liked your latest here and it is definitely an unusual astronomical UA-cam and that is excellent and who knows about UA-cam metrics and so on - Hollywood studios do focus groups for their largest budget stuff I guess and occasionally even give a broad release to something that doesn’t have extremely positive focus group data however derived - the art and science of show business wow teaching/learning STEM etc is an exciting corner of it and thanks again for this episode in particular!🌌🌌🌌🌌🌌🚀🌈☮️💟🤯🎬
Just perfect, science was never my strongest point. Your videos prove however, that the teacher plays a huge role in our understanding! A great teacher like yourself, and the lesson 'hits home'. Thank you so very much.
"Nothing can travel faster than the speed of light, except for...Nothing, which can travel faster than the speed of light." Brilliant!
This sentence made me feel like I was watching a Vsauce video 😅
I am going to use this sentence in my next presentation. which is on Tuesday and the topic is "Cosmos".
That can also be the answer of how something comes out of nothing, you are assuming that it doesn't, that's a rule, and there's no rules, there's nothing, so it just can, therefore 0 becomes 1. (at least this works in homotopy type theory, as a basic axiom to create the rest of the entire mathematics).
@@Ozelea 🙋🏻♂️Hi Abubaker, you definitely should! You could also play around with the structure and phrasing a little (even though Jade's delivery was excellent), if you wanted to that is. For example: "*Nothing* can travel faster than the speed of light...Except...Nothing, which *can* travel faster than the speed of light...In fact because *nothing* can travel faster than the speed of light it means that *nothing* else is faster than *nothing* when it comes to cosmic speeds - *not one thing*!" Or any variation you like really. A few other cool facts are that the speed of light isn't really about the speed of light. It's just the fastest speed that any information can be communicated between any two things. Light travels at that speed simply because it's a massless particle, and all massless particles *must* travel at that speed. It's our universes law. To give an idea of the vastness of cosmic scales you could try giving the speed in km/h or mp/h for a bigger 'wow' factor - and then tell your class how long it would still take them to reach the next nearest star or galaxy! But, interestingly, for an individual photon of light that long journey would seem to pass in precisely no time at all. Because for anything travelling at that speed time just completely stops - you would arrive in the Andromeda galaxy without noticing even the tiniest fraction of a nanosecond having elapsed. That long, long, long journey would feel like...*Nothing*🤦🏻♂️! Good luck with the project 💁🏻♂️✨
@@simesaid thank you alot. You are the best🙋♂️
Seeing Kepler's head on your body it's gonna give me nightmares until I perish
What are u doing here I thought u were to busy creating Tesla valves 😅
TESLA VALVES
Idk about you, but I burst into laughter at that part 😂
I love your physical demos! The one at 7:00 (ish) blew my mind. I had no idea you could demonstrate Doppler with water like that.
Hey there a big fan here
wow nick is here too
Oh, a collab between these two would be AWESOME! Edit: a word
Hey crazies
big fan
I’m not from Australia, but I love the fact that your earth model has Australia front and center
Lol...rip flat earthers 🤣🤣
Every country always shows itself as centre in atlas images
Mine doesn’t.
Yes, it’s mine.
@@mstandenberg1421 LOL love your comment.
Seriously those animations though... and the writing... and this video in general
I am in love
Simp
yeah it all SUCKED
@@brian8507 smashable indeed
6:14
Loved the bath tub Doppler explanation. Never seen that explained so beautifully. I would have liked to see you return to Keppler's wall at the end with the virtual horizon.
2:58 - Best CGI animation I have ever seen of a bounded universe.
Bonus points for adding a layer of simulated claymation! Bravo!
Wow Jade, you've truly outdone yourself on this one.
glad you enjoyed it!
@@upandatom 😊
@@upandatom I would like to talk to you about your claim of "nothing" expanding faster than light.
05:01 "until Edwin Hubble came along with a clean lens"
I'll see myself out now.
I actually thought that was what it was leading up to. ._.
@JT Raven Yep, that's the joke! :)
Absolutely deadly effective demonstration of Doppler Effect! Seeing a demonstration like that makes it readily apparent and practically eliminates the need for a lengthy explanation. I wish there were more easy to grasp demonstrations like this because I think it would have and would have had a huge impact on the general public's understanding of science in general.
I think, too often, the average person might have a good intuitive understanding in their own mind about something that they have integrated into their knowledge base, but when some science sceptic or a child asks them: Explain this to me so I can understand, they might struggle to do so because they lack easily replicated demonstrations like this. Imagine just being able to put water in a bathtub or basin and show Doppler Effect in a way that you can SEE it, rather than asking someone to first imagine what the sound waves of an ambulance siren might look like. Seeing is so important to humans for us to understand something. Seeing, for us, often produces that 'Eureka!' moment. You still might not be able to explain it, but you GET IT! and you get it immediately.
This is great stuff, and if you do nothing else with your channel but simply spread this demonstration like a meme, you will have contributed greatly to your fellow human's understanding of key scientific and cosmological concepts/theories.
Keep up the great work!
Wow, this horizon of the observable universe, behind which nothing can "escape" to reach the earth (our center of perception), this reminds me quite a lot of the event horizon of a black hole, where also nothing can escape, not even the light....could it be that the expansion of space-time is basically something like an inverse of a black hole? And what implications would that have?
Einstein's General Theory of Relativity also predicts the existence of white holes, which are the opposites of black holes. Even though a white hole has never been observed, I sometimes think that maybe the Big Bang was a white hole event. I sometimes also think that as black holes evaporate due to Hawking Radiation, that they might turn to a white hole when a critical mass is reached and it can no longer stay a black hole. At that point, the gravitational force can no longer overcome the repulsive forces of matter particles and energies inside, sort of like a supernova. These are just thoughts, though.
How you are still getting better and better with each video is ridiculous. In fact, HOW are your videos continually improving when they're already so good? IT'S A PARADOX. Please solve in a future video.
Well look at that! My other favorite creator that I met through a Tom Scott guest video! However while I now understand why some fishermen can hold their breath for 10 minutes, I still don't intuitively understand "how knot to hang a painting" :-/
So Jade just explained what i learned in a 3 month college course in 10 minutes. If school was as interesting as Jade's videos, I'd be a genius.
+1 this
Thanks for being so supportive all the time Rohin :)
Well I came down to the comments to say this exact thing, it's amazing how Jade's videos keep getting better. Congratulations and keep them coming!!
Jade's husband (in French or with accent), "Hurry up in the bathroom, Jade! I have to go!!!!" Jade, "I'm doing an experiment!"
hahahaha he was actually filming
i think shes australian dude
Her husband is French, though. She has him pronounce French stuff in other videos.
wait
Jade
science-related content with Jade
is that
I want Homestuck to get out of my head now
You guys- Up and atom, Veritasium, Science asylum, Real engineering, are all awesome!! The information you give is always authentic and the approach is always interesting. Thank you very much guys. You are doing an AMAZING job creating such an environment for education.
So much in love with this. The way you explained, visuals and the cherry on top is the outro music
I love that the earth is centered on Australia
*As it should be*
The real mystery is why weren't you inundated with moths while filming outside in the dark with a studio light pointed at your face.
the lights were trust me
they tried,but couldnt reach her,space was expanding lol.
The light is more luminous than the light bouncing off of her face.
If you have a porch light next to your front door, put a brighter light a few feet away to keep bugs from hanging out near your screen door.
I love all your videos, but this one is my favorite so far. The editing really good on this one.
I just love it when I see you uploaded a new video....and your previous ones too :)
I have never seen that demonstration of the doppler effect before with the moving dropper - it shows whats going on literally! Thank you for a fascinating video, Jade! :)
you're welcome!
the way you speak has a rhythm that kind of feels like you're singing.
the best visual explanation of the Doppler effect EVER. Your explanations are straightforward, without being insulting or TOO inaccurate. Truly elegant videos
Jade, this is so brilliantly done. What a marvellous explanation, delivered in your unique style, and which couldn’t have been done in any better way. Just fabulous. Oh... and bum to the critics, your presentation and acting in this is top notch, please don’t let them get to you. Much admiration and respect, from John, Wales, UK. 👍
It is depressing to know that we will never be able to see the stars beyond the visible universe
Just imagine all those photons that want to meet us but expansions was like "lol naw bro" 😭
And in the far future, we'll only see the lights from our own galaxy (unless the Big Rip is not true)
"It is depressing to know that we will never be able to see the stars beyond the visible universe"
I hear that those people are a bunch of jerks anyway....
Maybe we'll discover in the future a new way to travel faster than light so personnaly I'm not giving up
To be fair, there's quite a bit just in what we can see.
Hey Jade! Your content is overcoming itself constantly! Great work! Greetings from Mexico
Thank you!!!
Jade this was a great video! Wonderful job of explaining difficult concepts just enough to follow your overall theme. I had to laugh a bit though ... 8:18 Jade holds her rose, smiles, and mentions romance. Then 14 seconds later Jade nonchalantly tosses the rose aside. 😂
more important things to talk about
Amazing!! Nicely explained and loved the animations!!❤️
great video... the bathtub demo was the most straightforward way to demonstrate the doppler effect I have ever seen. very cool!
10:35 "How did it all begin? Well there's a computer program..."
We're living in a simulation
😂😂good one
*Just like the simulations*
That is a stupid theory. It requires a lot of assumptions and is plagued by paradoxes.
@@peoplesrepublicofunitedear2337 spoken just like a simulation bot designed to prevent people from realizing they're in a simulation.
It's too late.
We know this isn't real.
Stop pretending it is.
Our earth is 4 billion years old in a universe that is 13 billion years old. That means there are civilizations 8 billion years older than us. You think they couldn't produce this?
Why do you think we can't get off this rock? We've had the tech since the 1960's. Yet no one but elite astronots can supposedly leave.
Why do you think Antartica is off limits?
Watch the movie The Truman Show for answers.
@@peoplesrepublicofunitedear2337 well there are many anomalies which do support that theory.. like there have been cases of camera catching things which do not make sense(At least current knowledge/technology can't explain it) and scientists use them to support the theory.. it might come out as false but you can't call it stupid cuz if this is stupid then everything we know today is stupid since every assumption (theory) has at least once been called such
Great videos! As an Electrical Engineer and 'A' level Maths teacher, I really appreciate your methods of explanation. Wonderful content and I hope you have a lot of success to inspire and educate the youngsters coming through! Much love from the UK
One channel I'm glad I had on recommended.
Amazing content with such good animations and drawings and an even better explaination! Thank you so much!
Well that blew my mind! Bonus points for the visual on the Doppler effect.
You're like Hannah Fry: Your voice-accent combo is fantastic. I'd love to hear audio of you reading William S. Burroughs in a cheery, upbeat tone. The juxtaposition would be hilarious.
Hannah Fry > Jade Tan-Holmes because... redhead. ;-)
Hi Jade, I've watched many of your videos and they are all awesome - very well presented, fun and super informative. Thanks!
That music at the end is jammin'. I love it.
Visual aspect of this episode is really professional.
Okay this was really good! All I can do is appreciate you on this incredible work.
I love this channel. Can take a academically intimidating subject and concisely explain it, all the while encouraging you to keep up. Well done. The host seems very charming as well. Subscribed.
Great job, first time watching your videos now I’m excited for the next.
I had a proper 🤯🤯🤯 moment when you connected the expanding universe to the dark sky paradox. Love your work.
I love your earth graph, where Australia is at the center of the world 🤣🤣
I found this channel due to extra free time (covid recovery). I am already subscriber for some other similar channels but i just can’t stop watching Up and Atom. Jade is really sweet and super interesting with easy understandable, fresh way of going through topics. Keep on going! Cheers from Serbia
The illustration with the tub was the best I've ever seen, and I'm an old nerd. I've seen a lot of them.
If Olber had known about black holes, which can intercept light and not get hotter (getting cooler, even), he could have used those to muddy things a bit.
Your channel has quickly become one of my favorites.
aww thank you so much!!
Damn, the animation style is much more high quality now. Great work!
you are very talented in simply explaining many scientific ideas in a very simple way anyone can get through with it good job and continue
I really enjoyed how you went deeper into a topic that’s not usually discussed. Also I like how you referred to a specific show that’s related to this topic, so that we can learn more about this fascinating area (better than a generic endorsement).
This video was absolutely worth the wait.
Finally! A cup of coffee, and twelve and quarter minutes of pure physics with Jade 😊
Excellent camera work by the way!!
thanks!
I’ve joined Curiosity and love it. Highly recommend it. That series you recommended about math being discovered or invented “magic numbers” was excellent.
This is a really great video! I'm so glad to have discovered your channel. Please keep up the great work!
An infinite static universe would be gravitationally unstable as well though, it’s not only the finite universe that eventually collapses in on itself
Why will a static universe be unstable?

It was soo well explained ,Its sooo good to watch. Great work U&A , its just overwhelmingly good
This is the first time I actually understand a video about this theme, thank you!
Best visual description of doppler effect by using water drops in a tub of water.
I always liked the idea from this one Episode of Futurama in which the universe expands and the collapses resulting in a second big bang.
This video absolutely captivated me. So engaging and well written and presented, it unfolded in such an entertaining way, I was glued to my screen and grinning in parts from the wonder of it all. Thank you!
Your presentation and style make for a compelling combination that holds the viewer;s interest, entertains, and is overall very pleasing. Your gestures, expressions and intonations all help to keep, and direct our attention. Masterful!
This has become my favorite U&A video! The onion animation was so good. I remember during my army days, I took my night vision goggles and looked at the sky and it blew my mind. It was one of the most shockingly wonderful things I have ever experienced. Night vision goggles can see IR light and this video finally explained why I was able to see so much more. I knew the stars emitted IR light but didn’t know it was due to the red shift of the stars moving away. Amazing!
For visible stars, the cosmic red shift isn't a thing - any stars we can see (aside from occasional supernovae) are part of the Milky Way galaxy, and, rather than exploding away from us, are swirling around the center of the galaxy in the same direction as the sun, so some are moving toward us, others are moving away, and there's a mix of blue shifts and red shifts as a result. The Andromeda galaxy shows a pretty significant blue shift as it's rushing toward us at a bit under seven hundred thousand miles per hour (it's due to collide with us in about 4.5 billion years, so maybe not time to start panicking just yet).
The reason you see a lot more in the sky in infrared is that there are a lot of red dwarfs and brown dwarfs - small stars and near-stars - that are brightest in infrared wavelengths, and dim or invisible at visible wavelengths, so they're (more) visible when you switch to infrared.
Space: "nothing is allowed to go faster than light"
Also space: *actively expanding faster than light*
Great point, and seemingly lost on certain hosts.
I really love your videos! its very comprehensive and entertaining
First time watching one of your videos, very interesting. Thank you for your time.
Nothing can travel faster than speed of light
Except, *Nothing* can travel faster than speed of light
*Einstein has left the chat*
That's a good one!
Einstein did not say nothing could travel faster than the speed of light, his theories do not forbid it.
Great guy!!
That was brilliant.. It will be something I quote in future for sure.
@@jitteryjet7525 At the speed of light, there's no distinction between matter and energy
Some kind of big.... BANG 😂
Planets colliding happens all the time
I'm almost 60and LOVE to learn new things. Thank you so very much for what you do. Please keep em coming!
Nice way of explaining. Thanks and keep going
That was really great, Jade. Definitely one to show my daughters
:D !
This is such a clear explanation, thank you! I’ve also not seen such a clear demonstration of the Doppler effect before, very good. Question: would the sky look bright if viewed through a sensitive infrared camera? Also, does some light “shift” further into radio waves?
yes it would!
@@upandatom thanks!
Your presentations are lovely, thank you.
Thank you Jade. Amazing video. Both content and editing. never connected the "observable universe" and "expansion of spacetime". very smart. enjoyed it a lot. thanks!
There is one thing faster than the speed of space expansion:
The speed at which I clicked the Like button.
4:48 At this point I said: _"No, don't..."_ because I was expecting her to start promoting some online retailer or other that sells telescopes =)
I'll take explicit pitches by UA-camrs over repetitive ads chosen by Google executives every time I'm offered. But yeah it's got a strange 50s-TV feel to it then they cut to a sponsor promotion, even when Adam Ragusea does it, and he has all but mastered the art of the sponsorship segue.
This was really well explained. Really good analogies and visual explanations
Hi. Just subscribed. UA-cam suggested your video and the title had me interested. I watch a lot of PBS spacetime UA-cam vids and I really enjoyed yours it was much simpler to understand without having to stop go back and watch again lol. I have a short attention span and I zone out pretty quick but you kept me engaged. Thanks. I will be watching more of your videos in the future. Expect more comments
If the universe is expanding and the expanding speed is rising (because of dark energy) doesn't that mean that eventually that speed will pass speed of light and then we won't be able to see stars we see now?meaning the visible universe will shrink?
Indeed, things slip beyond the horizon out of the visible universe all the time, we just don't notice it. And as expansion accelarates, this will happen more. See en.wikipedia.org/wiki/Cosmological_horizon especially the section on Hubble horizon.
