This indie-documentary is one of the best documentary about cosmos PERIOD. That says a lot since i have seen more than i can count. But after this iam sure able to count or measure it hehe. A perfect serie of knowledge for an amateur hobby-astronomer from Sweden. Thank alot for sharing your wisdom to us in the younger generation, good sir!
This is probably the best space content on RU-vid. You are a gifted educator and I thank you for providing this content. Your How Far Is It series (and all of them really) are my favorite videos on RU-vid.
RU-vid award should be given to D.Butler!! I have been following many channels in this field so far best ever, can’t get better than this, vast knowledge of space amazing skill and unconditional love for teaching. We should appreciate it.
@@wadesharp11 I'm not sure about that, in Brazil it wasn't visible, if I remember correctly. I was expecting much more, since in the early 2nd millennium people got so scared it must have been really really big and bright
Anyone with even the slightest interest in the Sun, Comets, or Astronomy and what science has been and is doing should look at this wonderful video from David Butler. His video series are about the best on these topics that I have seen on RU-vid. As the Sun barrels through space taking all it’s planets and comets with it, us included, most of us live our daily lives oblivious to what is going on. David’s helpful illustrations will make it clear. Just wonderful.
Thank you so much for all your work Sir. It was awesome watching this over a cup of coffee before work today, I'll carry the perspective throughout the entire day now. Have a wonderful day.
Takes 40 years to leave the solar system (crossing the bow shock of the helioshpere) and even then, it will be another 40,000 years before it reaches the closest star (if it were going in the correct direction) That's 4x the entire duration of semi-recorded human history or 10x the age of the pyramids at giza. In other words, space is big and empty :'( and amazing!
To people that are well versed in this subject, it might seem slow-paced and somewhat juvenile. Some of the illustrations may also appear a bit unclear if not misleading, and the narration a droll monotone. Just guessing. But for beginners, it is well done mostly, and worth seeing. I admire anyone who does their best to disseminate interesting information such as this, especially about the fascinating space program!
Please don't take this as an insult, but your videos are a wonderful sleep aid. I've made a playlist of them and run them through the night with my screen off. I sleep very soundly and when I wake up in the morning I feel a little more intelligent every day...I'm guessing a lot of it sinks in! 😁 Anyways, thanks for your work. Oh, by the way, I do watch them when I'm awake, too. Astronomy and science are my favourite topics.
I listen to him going to sleep, in my headphones while working.......Halley’s Comet, I was 6 years old and my daddy rolled up a Bass Pro Shop magazine and we went outback where there was no light pollution and he showed Her. Told me my children will see it the next time it orbited. That sparked my love, my refuge and my sanctuary in the cosmos. I cant imagine what my life wud have been like had I never learned about space at such a young age. My 3 children love it and when my daughters was little girls they could name all planets and tell you facts about space. I love it. This man is amazing. Awesome voice too.
Since I was small, I saw David vidoes and also Sagan Series, and Jacques custeau series , ... All of them, great reserchers. David have a calm voice, and teach astronomy majestically. You are our best astronomy teacher David XD
Omg how have I only just found this channel. The way you articulate is bloody amazing. Thankyou so much for your work. Can’t wait to catch up with all your vids.
I really appreciate these videos; they really help me understand what a spec of dust on a spec of dust on a spec of dust on a spec of dust on a neutron we are in the universe! Keep up the great work; I love the classical music you play in the background of all your videos!
I love astronomy . unfortunately in the state I'm in I can't study this, but this channel gives me a great gasp of what the universe is , and I thank you for this david. You're one of my top subscribtions . i don't regret finding you channel from the great video you made over Andromeda
These are the best videos. Thank you David Butler. The improved graphics and animations really make the video so so much better. Your soothing and informative voice is great as usual.
Fantastic. What grade do you teach. I'd also like to know more about how you use the videos as part of the classroom work. The howfarawayisit.com website is made for teachers. Any ideas for improvement would be much appreciated. You can reach me through that website's contact page if you like. Thanks.
No matter how many of these types of videos I watch and no matter how articulately, or simplistically it is explained, I still cannot get a clear handle on the size of the Universe. Just when I think I've almost got my head around it, I'm like nope, that's just a few parsecs away.. I truly appreciate the time and effort that goes into making and explaining this subject matter, but I've realised trying to grasp the size of the Universe and truly make sense of it in my head is futile.. Fantastic video, thank you.
So true! I will never become tired of the wealth of knowledge the universe has to provide. It is too amazing to let go. The fact that some people couldn't be bothered by this knowledge really boggles my mind. How can someone NOT be fascinated with this????
Excellent video and narrating. I was only planning to watched a few minutes, but ended up sitting through the whole video. Great quality video in every way.
*Your narration rocks. The information you present is the best. Plus you always provide very interesting information. It's like taking a course on Astrophysics and Astronomy. Your videos are worth watching.*
I love watching your videos. There are far too many junk videos on RU-vid pretending to be educational videos, but your videos are the real deal. RU-vid needs more people like you.
And here in 2021, we are still hearing from both Voyager 1 and 2! 43+ years old and still going strong. Humans can do anything if we put our minds to cooperation and success!
Beautiful work, sir. Truly. Amazing images, graphics, narration - superb. And looking through the comments, I see you take the time to answer questions that people ask. That is a rare attribute on RU-vid.
Thank You for sharing factual information. It is too bad close minded people will never understand the wonders of our Universe. I love learning how the Universe works. Knowledge is POWER!
Amazing video. I find astronomy incredibly mindboggling to understand but I love every bit of it. Just here trying to learn new things, and this vid has plenty of it, at least for me. Well laid out too. Thank you so much.
No matter how many times I watch these programmes about the cosmos I'm never not in total awe at the sheer scale of our universe. This particular video illustrated just our own back yard in astronomical terms, and yet when the narrator says that the voyager travelling at approximately 36,000 miles per hour and that is very very fast in terms of our own velocity capacity, will take 1,200 years just to reach the oort cloud! Just think voyager 1 everyday is another 1 million miles from earth, the distances are simply just beyond human contemplation. I'm going out on a limb here but I strongly believe we will never ever ever have the technology to travel to these long far out destinations for eternity. We will visit other planets way off in the future for certain, but a time will come when the human race will come to realise the maximum of our capabilities in terms of our biological strengths and our intelligence.
We could build generational spacecraft, have a breakthrough in cryogenics, or merge with tech (cyborgs). Otherwise our fleshy bodies will never see another star system in person.
This video really made me appreciate and realise my life that how delicate and lucky our existence is in the corner of this tremendous erratic universe. oh my god, i really love my life and really wanna thank the mother universe for letting to have life experience. And THANK YOU soo much for the video.
David I have to say this is wonderfully put together. I follow a lot of these type of videos and RU-vid and Discovery channel and have to say your voice over is perfect for it (as well as your research). The graphics are spot on and it is a relief to see or should I say hear the background music (which is great) is just the right level to not drown out your commentary.I too watched Halley's comet back in 1986, I will be 87 when it comes back around again and hope to still be also still around to witness its splendour as well as to be able to say I saw it twice in my lifetime.I have subscribed and look forward to watching more content from your, keep up the good work sir!
I never used to subscribe to a channel. But next to NASA and Hubble this is the 3rd subscription I just subscribed. Well worth to watch this guy and these vids full of amazing information you barely get anywhere else compressed in short videos. Thank you!
Thanks, David Butler! The pandemic had given me the opportunity to go through your videos on How Far Away Is It. Haven't done this much math since Stuyvesant High School (class of 1970).
I love this series. However, I nearly jumped out of my skin at 13:28 - that glass shattering sound effect was so unexpected in such a relaxing video, I thought someone had broken into my house. Certainly made me pay attention.
They are powered by RTG's ( Radioisotope Thermoelectric Generators) using Plutonium 238 which was produced in early test reactors and is now in such short supply that deep space missions are severely limited. These very small amounts of radioactive materials produce significant amounts of heat for many, many years making these deep space missions possible. No longer being produced, this is one of the motivations for developing breeder reactors to not only make better use of limited uranium supplies, but this Plutonium 238 needed for space exploration....
Thank you, I struggle with the maths, but your explanations help a great deal. The distances involved are incredible, there will need to be a massive jump in technology to visit even the closest stars. Once again thank you for the efforts you have made in creating and uploading these videos.
Not sure how I arrived at this RU-vid video? With that said, I watched the entire thing and my mind is now blown! I can't wrap my head around some of these distances or the number of years it takes for a comet to travel. I'm also not sure why all of this information is relevant or needed? We are so so so small in relationship - we just don't make a difference.
@@virgilmccabe2828 I really agree with you but also feel we are so small in the scope of things that we really don't matter. On the scale of infinity, the earth is smaller than an isotope..
U have to have the divine view, otherwise, it seems like we're just miniscule fleas riding on a humongous elephant for only a brief period of time!! U know what is the lifespan of a flea??!!
Fantastic video! Everything is very clearly explained, awesome visualisations. The historical elements are very useful to put things in a time-depth perspective, which helps to conceptualise the great distances we are dealing with, as do the continuously indicated spatial distances in the video. The video is a perfect mix between real images of objects and events in space and schematic materials and models. The pace of the video is not too fast, which makes it easy to follow and enjoy for a non-astronomer like me. The sound quality is great, too.
I especially appreciate the pace and the sane dialogue as a wonderful contrast to the current trend of videos where they edit out the speakers' inhalations so that there is no break in between sentences or paragraphs. These videos are SO cool! :)
Holy crap, this was an amazing video!! I never even knew of the satellites outside earth like that, especially around L1 (also which I've never heard of before). Simply stunning!
David, Just wanted to let you know how much I enjoy your efforts regarding your very well presented information, but also how you present it in such a complete fashion. I've been one whom has tremendously enjoyed astronomy as a hobby since I was a child - I am now enjoying my 50th loop around the sun. Much thanks for sharing your experience and knowledge with us. - Jeff in Vancouver Canada
Thank you thank you thank you. I wish more people would take pride in their videos that you do. I appreciate you helping me to learn about space, and I've subscribed. 🙂🇨🇦
You are a modern day Tycho Brahe or Johannes Kepler. Using mathematics like it was the air you breathe you have given me a picture of the Universe (as well as the Microverse - can I copyright that, BAC? ) that I am certain is as close to the one you have and by extension the best one there is. As I believe you are the foremost communicator of this knowledge on our planet I just want to thank you. I hope you continue to make these videos - and I have seen as many as I can, many times - until it is time to pass the Torch to whoever is able to carry it. I'm pretty sure you know how important you are but its always nice to know how you affect others. And I am no dummy, going to University still at 60, aiming for a Doctorate in Music. Now that's the biggest number I have ever come across. Six O. Do they keep getting bigger?
