I have seen this video more than a couple of times and still believe this is maybe top 3 all time universe videos just because of the pin point accuracy and communication skills to such a topic. Even not knowing anything, here, you can get more than a glimpse of our reality and how it all began
No sound effects, no cuts every 10 seconds, no horrible CGI effects..... Those people producing documentaries for TV should take a hint from this series. It is amazing that an "amateur" is able to produce content that is way ahead of what the professionals are able to do. This is the way content about space should be presented, and there is enough information in every one of the episodes that I need to watch them several times.
This guy's videos are some of the best for making these much discussed concepts understandable to ordinary people. He doesn't used hype, or toss out jargon like a lot of the superstars of science, he just carefully explains things as they have been understood to be, and therefore I get a better understanding of the ideas, a plain view so to say.
Yeah I agree. This honestly should be how people are taught about these topics. I have a feeling this will outlast and become a new model for how educational material goes forward...
What an absolute masterpiece of presentation of difficult ideas with enough math and physics to go beyond dumbed down popular science alternatives. My hats off to you dear Mr Butler. Teaching is definitely your calling. I almost forgot, your voice is also spot on. 🇨🇦👍
This answered my question about the big bang model. It makes perfect sense visible light only reaches us from as far as the time of point were cooling resulted in release of the trapped photons. And the photons went '' kaboom! who wants to see!''😮😮😮All jokes aside, I don't think I've seen any presentation related to this topic to even come close to the informative quality here and I think Mr Butler deserves an Award for presenting cosmology in such masterful and also down to Earth manner.
This series is the best educational tool of all astronomy videos available on CZcams. It is presented in a format that is conducive to learning. It has one narrator speaking in a calm, clear manner at a pace that allows the listener to absorb what is being said. It references to other chapters in the series that allow the viewer to "brush up", if necessary, to ensure the viewer can comprehend the material. Well done, sir!
Im listening on ipad to David whilst typing this on iphone. He sure knows his stuff. Im starting his videos from the beginning of his CZcams videos 7 years ago. The dudes voice is great for astronomy. Awesome David. Thanks
Love it. I wish my family and friends understood my love for science. The only time I really get to enjoy this subject is by myself. And when I do discuss the how, what and why in the simplest terms they shout "geek alert"....
Excellent video. I cannot thank you enough for creating this and having it freely accessible as well. The quality is top notch ! The content is superb. Needless to say I learn a lot from this. Also rewatching it for deeper understanding.. !! 👍😊
Thanks, I am not educated, but I find this very interesting and entertaining.thank you very much for your sincere efforts to bring science education to everyone
How do you not have more subscribers or views. The explanations are as understandable as you can get for laymen like me and the soothing voice is nice. The “how far” series should be a televised documentary. Thank you for the education.
despite the difficulty understanding physics concepts.. i have huge interest, i'm following and listening multiple times... hoping to learn alot about the cosmos... amazing work!
Hi David, I'm reviewing your video books on a new, large 4k tv and am very impressed with how beautiful it all looks. I'm recommending your coursework to my technically oriented friends while we're all hunkered down to beat the bug. I can now read the on-screen equations, and notice other details. What fun to spot Ayrton Senna in his McLaren MP4 racing off to a distant galaxy! Hope you are happy and healthy in these interesting times.
Wow, it's mind blowing to think how much knowledge humanity has gathered for a fraction of time (like 10000y). And this trend looks to me as rapidly accelerating with every new research, discovery, invention, technology, etc. Like all this is interconnected, more you know, more you want to know. I like one thought : - we've learned so much about the universe with its life, and yet we know only a fraction of the big picture.
One of the best presentation on CZcams about cosmology. Mr Butler have several high quality presentations. Worth watching all of them. I have shown most of them to my kids. Thank you for sharing it.
Mr. David Butler; thank you so very much for your wonderful videos! They're greatly informative and enjoyable for a school dropout such as me! You are very good at this! Please continue dear sir!
I'm hooked on these videos, it's so amazing to see the birth of our universe and if our own solar system, the mathematics you explain is excellent for bringing it down to size so someone like me can understand the processes, thank you for a great presentation.🌎
Your channel has quickly become one of my favorites, not only love watching it to educate myself, but great for my anxiety when I’m trying to go to sleep, but can’t.
Gloriously optimistic about the life after watching this. Even when I don't quite get it....might have to watch it twice, thrice or even more! Somehow thought, it lifts my spirits! Thank you!
This is the best brief lecture on this subject I have seen. I find myself in a state of wonder. Thank you for tying my piecemeal understanding together so beautifully. This is Templeton Prize standard pedagogy. It seems perfectly piched for the competent amateur who is well beyond the fundamentals of the field but far from expert. Thank you again and please keep producing these videos.
This answers quite a few questions that have been on my mind for so long. Thank you for explaining things in a way that make sense to so many. I'm looking forward to the new experiments and the information that they will be providing! Keep up the great work that you do!
Rated 5 STARS ! ***** ! This is a fine video that explains several key concepts about the CMB and its relation to the current Big Bang model of cosmology. WELL DONE ! An excellent adjunct for any high school science class with an astronomy component or lower division college course in Astronomy. Easy to follow, clear concise language, excellent graphics. BTW Arno Penzias name is hard to know how to pronounce. No matter, t Thank You !
So nice to have you back! Been looking forward to the new video book. I recently moved from the San Diego area to AZ (I really hate this state! I miss CA very much & can't wait to get back!!!) - so over the past few months I've hardly been online at all which has made things go even faster. Before I left I had watched all the other video books in your series -not just once, but at least two or 3 times- and each time it was a pleasure. Thanks for all the work you put into these.
As ALWAYS... Thank you! I learned a couple things from this video. I'm pretty well read but you my friend are definitely ahead of the times. Look forward to more.
Keep it up. If you watch enough videos on a topic that feels that way it stops feeling that way. You may not get a rigorous mathematical understanding, but you'll get build a working vocabulary for the topic. Then when scientists make a new discovery you can you'll appreciate it more.
Yet another fantastic series. I lost count of the many times i listened to your videos. They are on repeat in my ear while sleeping (after i heard them many times awake) Thank you from Sweden!
I think someone from religious background used this video to disaprove astrophysics or prove a creator and now the comment section is filled with people having "intelligent" questions. These are such amazing videos, full of knowledge and yet.. amazing how it has become acceptable to attribute everything to a sky daddy, but very hard to accept that we may not understand everything now, we are trying our best to understand from what we have, and may never understand. "I don't know" should be an acceptable answer, but the fear of unknown is still in play.
Same here. Also I don't understand why it's of such importance for some that, e.g. the big bang did no happen... I mean, I personally don't really care, I just accept that our current knowledge indicates that a big bang did happen.
@@Zahnom Exactly, if tomorrow, we have better theory for the origin of Universe than big bang, I'd be interested in that as well. Its not like I've made a religion out of big bang and suddenly if it's disapproved, my existence is false.
Used by a religious person to disprove astrophysics? lol they can use deer scat to do that, they don’t need educational materials to be dumb asses, they can do it with two sticks and a rock. Their stupidity and arrogance know no bounds.
Have you ever noticed how random numbers rarely appear "random". It's the same clumping-up principle that's at work when it comes to the surface of last scattering. Hence, by pure chance, recursive patterns are bound to manifest.
all and every video ive watched on cosmology were bits and pieces and you sir put them all together in one video so i can see the biggest picture ive ever saw thank you
Excuse me! Where did these first electrons, protons and photons come from? Universe began from a state of singularity with an infinite temperature. Cosmological BigBang is a convenience item . Presumably 30 microseconds later minor temperature variations appeared as microwave background.
they came from the universe. at some point it collapsed, everything heated up to the point of hydrogen dissociating into electrons and protons, and becoming opaque due to the lack of photons being created.
I'm curious, how do we know what the cosmic microwave background looks like anywhere else in the universe? We can point our detectors in any direction from our satellite, but how do we know how much of the microwaves are coming from nearby, and how much of it is coming from a great distance? That is, how do we have any depth information for each point of data, or is that data map just showing the total we receive here in the vicinity of earth, from all distances in that direction? How do we know it isn't completely different 100 light years away, or a thousand, or a billion?
The wavelength tells us how far away the radiation came from. And, as it is all stretched to the microwave wavelength, we know it all came from the big bang 13.8 billion light years away. No matter where in the universe you are, you will see the same thing because no place is any different than any other place.
Hello David. I've been wondering what's happened...after seeing your several other videobooks, most of them at least two or 3 times(!!), I kept waiting & waiting for the next one to come out. Well finally, last Sept., it did! And I thought that this new series all about the λCDM model. This was exciting, as it, before I watched it, seemed as if we'd be getting more and more deeper mathematical, astrophysical insight/education. This turned out to be entitled "How Old Is It?". Has there been some problem that has prevented you from doing more on this one? If so, IKR completely. Anyway, of course, right now it's already mid-Feb, 2018, so, I'm not holding my breath for any more soon, anyhow. Though I'd really be delighted to see a new one pop up. Thanks again, for all the hard work you've put into this series of educational video books. One last thing: the main reason I love your presentations so much is that you have the perfect bridge between those dumbed-down PBS-style science documentaries, where they have the same 10 or so talking heads pontificating and explaining certain things for us, the "uninformed"; between those and the more super-academic university lectures which usually presume an already steady knowledge of the subject at hand, and so doesn't take the time to, at least, "simplify", that is, go over the basics of the particular subject. These are just right for one who isn't an astrophysics major at Harvard or Cornell, or Cambridge, etc. (or Oxford, where you matriculated), but also for one who has enough knowledge to not need a dumbed down high school version of "science class". Anyway, thanks much for your work. Hope all is well with you & that, sooner or later, we'll see the rest of the "How Old Is It?" video book. Toodles...km.
I am in research mode on how old is the Solar System and Earth: getting into exoplanets and geology. It will take the year I think. Then 'life' - evolution in 2019. In the meantime, I have the 2017 review coming out very soon. I'll also be updating nearby and distant stars. Thanks for staying tuned into the channel. It has been very satisfying to see the number of subscribers like yourself grow.
Wow! Great to see you are back! The explanation and visuals on baryogenesis, neutrino decoupling sequence was very helpful. I did not understand that part of the big bang before :)
Thank you. For these amazing videos. I probably will have to watch them more than once. And I will. (BTW, in this particular vid music is not disturbing. And I love use of YT chapters. Well done 👍)
I have seen this video more than a couple of times and still believe this is maybe top 3 all time universe videos just because of the pin point accuracy and communication skills to such a topic. Even not knowing anything, here, you can get more than a glimpse of our reality and how it all began
No sound effects, no cuts every 10 seconds, no horrible CGI effects..... Those people producing documentaries for TV should take a hint from this series.
It is amazing that an "amateur" is able to produce content that is way ahead of what the professionals are able to do.
This is the way content about space should be presented, and there is enough information in every one of the episodes that I need to watch them several times.
"Professional" means. gets paid. they want you to keep watching, not to actually learn something.. because then you don't need them anymore ;)
Wow,I learned more from this video than what is taught for an entire semester.The classical music is a bonus.
Am i the only one who picks videos iv already seen to listen to when going to sleep? His voice calms and soothes me.
I used to listen to Carl Sagan's Cosmos while falling asleep. Try it.
He has a really nice and articulated voice, it relax
Almost everyday..
This guy's videos are some of the best for making these much discussed concepts understandable to ordinary people. He doesn't used hype, or toss out jargon like a lot of the superstars of science, he just carefully explains things as they have been understood to be, and therefore I get a better understanding of the ideas, a plain view so to say.
Thanks.
U?
Yeah I agree. This honestly should be how people are taught about these topics. I have a feeling this will outlast and become a new model for how educational material goes forward...

Even with such an interesting subject, David's voice and the classical scores are good sleep medicine! Pleasant Ethereal Dreams to all!
This video explains all of the concepts so easily and it makes so much sense. Thank you David Butler.
Very clear explanations. You are my hero
They're so great.... thanks
Best series for the layperson on the net..especially HOW we know what we know
Love it. I wish my family and friends understood my love for science. The only time I really get to enjoy this subject is by myself. And when I do discuss the how, what and why in the simplest terms they shout "geek alert"....
Been there, suffered that.
We need geeks.

Just brilliant work David. We are so lucky to have productive Inquisitive minds
Did you know that at the end of space there’s a little doorway which leads to a room where an old guys sitting
Yes I have heard rumor of this,they all have shoe boxes on their laps. Some boxes have dead cats and some have lively puppies . ..far out
Thank God you're back Sir! I'm so gonna enjoy in this one. Thank you, regards from Sarajevo, Bosnia and Herzegovina.
Dudes melted more minds than all of the acid ever created. Wow. A phenomenal teacher
Underrated comment
The art in science is here. As is the science in art, I suppose.....

As ALWAYS...
Thank you!
I learned a couple things from this video. I'm pretty well read but you my friend are definitely ahead of the times.
Look forward to more.
This is rather esoteric for me. I feel like I am in a class for a lecture on particle Physics.
Keep it up. If you watch enough videos on a topic that feels that way it stops feeling that way. You may not get a rigorous mathematical understanding, but you'll get build a working vocabulary for the topic. Then when scientists make a new discovery you can you'll appreciate it more.
this is real education, awesome job
Chemical is a living thing of the universe. Thank you Mr. David Butler for your video.

The surface temperature of our sun is 5777 Kelvin (1:08 min). I love your videos. Thanks for the work and very best regards from Germany.
Thank you David Great Teachings for the Lay person Like myself to grasp the wonderment of our universe
Nice & compact explanation of the esoteric processes of universe formation.
I go to Hickok45 for guns and I come to David Butler for cosmology. Yet both men are indistinguishable and I love it
Hey me too!
all and every video ive watched on cosmology were bits and pieces and you sir put them all together in one video so i can see the biggest picture ive ever saw thank you
I especially enjoyed listening to Bach’s “Wachet auf, ruft uns die Stimme”.
Phil Mc
Thank you so much for this recording material. I've really loved it to the most ..
we missed you!
david !!, an excellent video and lesson again. you are born to be a scientist and a teacher
of the highest level.
90% above my iq level but still watch all as you sir are totally engaging
Geat to everyone getting into astrophysics, i love this!
Gosh, I have seen that CMB map a thousand times and now for the first time I understand. Now I know the meaning of the word awesome.. Sincere thanks
Great and clear content, perfect timing and rhythm even for may horrorific english. Thanks :)

Many people misunderstand the word "theory" in a scientific context. It does NOT mean just a guess or even hypothesis.
Well said.
@Dupa Essex we are all hardwired to be religious in some way. basic human evolution, you're no different.
Hello David. I've been wondering what's happened...after seeing your several other videobooks, most of them at least two or 3 times(!!), I kept waiting & waiting for the next one to come out. Well finally, last Sept., it did! And I thought that this new series all about the λCDM model. This was exciting, as it, before I watched it, seemed as if we'd be getting more and more deeper mathematical, astrophysical insight/education. This turned out to be entitled "How Old Is It?". Has there been some problem that has prevented you from doing more on this one? If so, IKR completely. Anyway, of course, right now it's already mid-Feb, 2018, so, I'm not holding my breath for any more soon, anyhow. Though I'd really be delighted to see a new one pop up. Thanks again, for all the hard work you've put into this series of educational video books. One last thing: the main reason I love your presentations so much is that you have the perfect bridge between those dumbed-down PBS-style science documentaries, where they have the same 10 or so talking heads pontificating and explaining certain things for us, the "uninformed"; between those and the more super-academic university lectures which usually presume an already steady knowledge of the subject at hand, and so doesn't take the time to, at least, "simplify", that is, go over the basics of the particular subject. These are just right for one who isn't an astrophysics major at Harvard or Cornell, or Cambridge, etc. (or Oxford, where you matriculated), but also for one who has enough knowledge to not need a dumbed down high school version of "science class". Anyway, thanks much for your work. Hope all is well with you & that, sooner or later, we'll see the rest of the "How Old Is It?" video book.
Toodles...km.
I am in research mode on how old is the Solar System and Earth: getting into exoplanets and geology. It will take the year I think. Then 'life' - evolution in 2019. In the meantime, I have the 2017 review coming out very soon. I'll also be updating nearby and distant stars. Thanks for staying tuned into the channel. It has been very satisfying to see the number of subscribers like yourself grow.
I still can't believe this guy has below 50k subscribers.
Like the universe there was a time when it was very small now look at it.
Damn nice pool
This episode should be called, "How Cold Is It."
Thanks for your content Mr David
Love watching space documentaries
Thank you sir. Well spoken and delivered.
Wow! Great to see you are back! The explanation and visuals on baryogenesis, neutrino decoupling sequence was very helpful. I did not understand that part of the big bang before :)
David, I love the way you explain things, you must have put a lot of work into this.
Thank you. For these amazing videos. I probably will have to watch them more than once. And I will. (BTW, in this particular vid music is not disturbing. And I love use of YT chapters. Well done 👍)
