I listen every night till I fall asleep,that voice is better than any sleeping tablet....then I will watch again the next day and watch it properly because this series is the best I have come across so far “anywhere”....THANK YOU !!!
Just fabulous. I absolutely love your lectures. So much crap these days with CGI masking a complete lack of substance. Please continue making these wonderful shows for posterity, as well as for your current audience!
Finally a space channel that gives space the respect it deserves! It took so long for me to find this damn channel, sifting through all the “space documentaries“ that feel the need to spice things up with English accents, cgi and loud music with bass drops of all things! Thank you so much for this channel!
I agreed Mr Butlers channel is excellent. However, there are seldom genuinely made science documentaries with "English Accents" that utlize electric guitars, thundering war drums, and the general rock and roll feel of the type made, lets say, elsewhere. The English accent science documentaries of today are gennerally, slick, understated and beautifully filmed. See David Attenborough, Brian Cox, Jim Al Kalili, Alice Roberts etc. All covering science, without the need for the electric guitar or rock music. Bass drops? Wtf you on about? Enjoy. Cock.
@@Jobby1975 am I reading this comment right? It looks like we’re in agreement and then sort of wanders off into a gray area and then ends with outright hostility? I’m gonna need an English professor or maybe a psychiatrist to help me properly assess this comment.
Mr Butler, you are a treasure to all those of us who seek to expand our knowledge of the cosmos. All blessings to you for sharing your scholarship with your fellows so freely.
Maybe 75% of what I learned about astronomy (which is not much) I learned it from this channel. Mr. Butler makes me feel like I am in a classroom. The only difference is: no test, and tuition & fees! (although the videos are bona fide "textbooks"). Thank you very much, Sir. - Aimé
Wonderful job, Mr. Butler, absolutely remarkable! I'm not a scientist indeed, my education is pretty average and math has always been my "black beast" but I do love the way astronomy makes me dream and your documentaries are really the best of the best in "divulgation for simple minds", hands down! Thank you 300.000 times per second! :-D
Steve, You are the first Teradatan to comment on my videos. Thanks. I loved those good old days starting up the first massively parallel OS/database on the market. It was exciting. Now I find that what the Hubble Space Telescope has found is very exciting.
Its easy to say a star is 2 1/2 million light years away but to take light that long to reach us is both all inspiring & mind blowing to even comprehend those vast distances.. In both time & space
Mr. Butler thank you for sharing your amazing work with the world. Your content and the way you present it is exceptional and world-class. You are eloquent, knowledgeable and inspirational. Kudos to you sir.
It's really hard to get your head around the fact that even travelling at the speed of light which is 186,000 miles per second it would still take you 400 years to get to the star beetlejuice.
About Tycho Brahe's observation... he called it "Stella Nova" - hence the word "nova" which survived into modern science. (Not important, but I am Danish, so......) About this channel.... so refreshing not to be talked to as a child or a total ignorant - so popular in modern documentaries. No techno music and the words "totally awesome, dude" and no stupid comparisons "distance to the moon - you would have to stack x amount of schoolbusses on top of each other". I like to be talked to as if I was an intelligent person - even though I only understand part of the segment.... ;o)))
mind blowing in 4K ! thank you so much for your work, I am so looking forward to the launch of the James Webb space telescope to look deeper and with more clarity than we can imagine, exciting times indeed.
At 5:44 if I interpret the video correctly I see some of the stars moving also, amazing. Your videos are more interesting and educational than "proffesional" ones.
At 20 Million miles per hour, every hour of every day, over a period of one thousand years, the total distance covered by SN 1006 is mind numbing and that with no pit stops or potty breaks. All that distance is just a tiny drop in the expanding bucket of the Universe. Our experience of the size of the Universe, if we could experience the whole of it, would outright kill us.
How beautiful and captivating it is, the Universe is the most hostile and anti life environment ever known......It seems some scientists are donning their rose tinted glasses , with their continued statements ,"There must be countless Earthlike planets" ....while Earth probably is a very rare oasis in this vast universe.....some scientists would state "It's a miracle that we're here at all".....While with the billions of galaxies , even the most chronic sceptic would admit that surely there must be earthlike planets in some "Goldie Locks"zone....Fact is that we most likely will never know, certainly not "life" in other galaxies,...and better take good care of this only known oasis we're priviliged to have evolved on.....
You taught so many people so many invaluable things that so many others could have done but didn't. The way you've explained how we're able to tell the distance of objects just blew my mind and blew so many of my friend's minds that were skeptics and always said how would they know what it's made of and how far away it is and now they know because of you. Regardless of how many subs or like you may get what you deserve a trillion, but regardless of that just know you've helped thousands of people. Thanks again
i agree, fabulous voice while i day dream about the universe.... this sort of lecture should be compulsory to every 11-16 year old, imagine the talent we could nurture if this was done.
Let me echo the praise I see in these comments. This series of videos provide accessible explanations of complicated concepts, with excellent graphics supporting a non-sensational narrative. I first became interested in astronomy over 50 years ago, aged 9 or thereabouts, when Pluto was still a full planet and Bode's Law still got the occasional mention. It's fascinating to see how much we've learned since those days. Keep up the excellent work!
You are an amazing teacher. I am learning much here. The Universe is endless, so to speak, but I believe this is not the only Universe. The construct of God is unlimited. I pray we can understand just a bit before we perish..
Your videos are great. The one describing quantum chromodynamics is very insightful. Keep us posted on any more details found. Is there any information on the temperature inside neutrons and protons? Seems to me it is a very violent place.
on my 2nd watch thru.love the background music at the perfect level and David's soothing voice guiding us thru these amazing videos pack full of interesting facts.thanks for this series :)
I have been watching Francis Pryor's Britain AD along with David Butler's How Far Away Is It. The time scales are vastly different, but both explore the unknown past and try to reach a rational understanding. Considering my place in the scheme of time, I have come to the conclusion that it don't make a damn that I burnt the toast at breakfast.
Dera Dr Butler....The only I can say...is ---Muito Obrigado---- (Thanks in Brazilian Portuguese) and ---Tack saa hemskt mycket---- ( the same in swedish), both my languages. Little world, enormous universe. Thanks for showing us how small we are....yet so big, if we want.
I remember when i used to naively think what we saw at night were mostly galaxies. But the beautifully cosmic sight on a clear night in the country back in 70's But we only see a tiny bubble of a % of nearby stars within a galaxy of TRILLIONS!!
David, at 22:00 min, do you have any info on the small opaque gas/dust cloud (dark nebula) in the upper left hand quadrant of the Trumpler star field picture? Thank you for your time and effort!
To David Butler from James U. Which reality are you from? Because in the internet of my world on Earth, the stars and sun are different and you don't exist here. Please let me know asap. Thank You.
This video makes me jealous, if the human race makes it through the next 1000 years surly after that they will explore these places, wish I could have been there to explore this awesome universe, I guess I will be somehow through the human spirit
If the milky way🌌 was made like a supernova, what would be the weight and size of the stare to creat it? Thank you.

This guy sounds like a straight up soulless thug, no emotion. He could smash people's fingers with knowledge and not even give a shit. He violates people in the brain with facts and is cold as Antarctica. I would hate to meet this guy in a dark alley, where he could practice his perversion in relative isolation, while searching for some emotion that never comes... because it cannot. This guy is so terrifying, more so than anyone else I have ever seen on youtube.
I Wonder if you were on a planet in the thick star cluster the daytime sky would look like with each stare only being a third of a light year away from each other...
Is the rate of core collapse for red supergiants a predominantly constant and linear process, or does the rate of collapse (post initiation) decelerate gravitational mass compression due to the inverse-square law?
9:00 - 10:30 - I wish we'd get to see one in our lifetime, or in mine in the next 40-odd!?-ish maybe yrs!! 10:11 - Come again, the shockwave would be tearing us apart right now! Please elaborate to this point. Like literally, like a melon as the Earth with an M-80 Airbomb detonated inside it!? Or like an orange with its skin peeled off! or shotgun peppered when the contents of the Kuiper belt and Oort cloud are shot towards us!? or just deadly lashings of immense heat and gamma radiations!?* *this is how Planet Hulk 2 comes about! Population: Red Hulks! :D Also, what of the Sun and other planets of the solar system
Question Cosmic recycling. If a star dies after using up all its hydrogen and explodes. How does a new star form without hydrogen gas?? Sorry if it’s a stupid question.
At 22.21 of the video at the top left corner there’s a strange and dark part of the image where those bizarre shape and weird tale blocking light from the stars PLEASE SOMEBODY CHECK IT OUT! I could use somebody else opinion on this and I’d like to hear what people think!!
The prominent dark patch, close to the center of the cluster is a so called Bok globule: this is an isolated and relatively small dark nebula, containing dense dust and gas. These objects are still subjects of intense research as their structure and density remains somewhat a mystery.
Imagine a fly in a Cathedral. That fly is a Neutron. Now Imagine A Cathedral full of flies. Multiple The Mass of a Neutron by the number of flies. Now try weighing a spoon full . Pretty heavy.
Mr. Butler I'm certainly no cosmetologist & with all due respect!.. Shouldn't the universe be slowing down and not speeding up ??!..I just don't get it!..except to say MAYBE gravity is weaker at the furthest reaches of the universe..Don't know how else to explain it..any bang or explosion inherently slows down over time.. Correct ??
Frederick, I have a video book on this "How Old Is It". It's first two chapters after the preface are on the big bang. Let me know if they don't answer your question.
We base the expected lifetime of a star on its mass. Analysis of countless thousands of stars give us the metrics to use. Our sun's mass leads to a prediction that it will be a star for 9.5 billion years. It looks like it is around 4.5 billion years old now. So it has 5 billion more years to go.
Why these gets complicated and make us explain so much complicacy, than its easy to know every solar system will be same as our sun system. What u describe may be 90% imaginative. What u think??
I listen every night till I fall asleep,that voice is better than any sleeping tablet....then I will watch again the next day and watch it properly because this series is the best I have come across so far “anywhere”....THANK YOU !!!

I was wondering, what did you mean by "the western sky" when talking about Kepler's supernova?
23:06 this just blew my mind. I had no idea this was possible. By that calculation, our solar system would contain 20,000 stars. Unreal.

Maybe if you think the human race will ever explore these places, you haven't really understood "how far away it is".
It is a good point, it's unimaginable how large it is.
Still enjoy the "older" videos w/ MUSIC. Sure this isn't PISMIS 24? instead of PRIMIS 24? I tried to look it up. Thanks
Nice boat
And Bach playing in the background...OVE IT...but I still have a problems with distance...
21:15 I wonder how far those two stars are from each other? according to visual it's less then their radius
Muy interesante 1-10-2018
Very intresting
I wonder if Super Massive Black Holes are formed from a Globular Cluster of stars all crashing together in the middle at the same time.

I Wonder if you were on a planet in the thick star cluster the daytime sky would look like with each stare only being a third of a light year away from each other...

Also, what of the Sun and other planets of the solar system
Uneducated comments based on movies. 🤨
When our Sun explodes I'm hoping to be in Proxima Centauri 😂
What is a point charge and what dpes it mean that an electron is a point particle?
If the Milky way is 40k light years across how can galaxies few hundred light year be closer than our own galaxy across ?
WR stands for "Wolf-Rayet", right? Isn't R-136A1 in the Large Magellanic Cloud a Wolf-Rayet star?
Yes it is.
what would we see if habour fly to outside of solar system？
Question Cosmic recycling. If a star dies after using up all its hydrogen and explodes. How does a new star form without hydrogen gas?? Sorry if it’s a stupid question.
So far, only a small fraction of the Universe's hydrogen has been used to form stars. There's plenty left for current and future generations.
David Butler thank you
Everything is spoken matter of factly, but are they truly?

how far away is it ?

Mr. Butler how can someone determine the lifetime of the sun? I heard it is around 13 billion years
We base the expected lifetime of a star on its mass. Analysis of countless thousands of stars give us the metrics to use. Our sun's mass leads to a prediction that it will be a star for 9.5 billion years. It looks like it is around 4.5 billion years old now. So it has 5 billion more years to go.
