David, this series and all you wonderful videos are superb - thank you so much for all your wonderful work! Such a collection of brilliant work you have compiled
David Butler! Wow, look at all your subscribers! I always have to check back because this was your first (and most exciting) series. It is still my favorite. "It did not wobble"! Love it & Congratulations!
I have to say sir, your amazing. The simplicity of your analysis of space is the best I've ever heard. Albert Einstein famous quote if "you can't explain something simple then you don't understand it enough" definitely holds true to you
Around 10 million stars are known to orbit within just a single light-year of the galactic center. Some 30 million stars exist within the central bulge, stretching 27,000 light-years from end to end.
I'm sorry. I mixed up "central bulge" and "bar core". The central bulge is at the center of the bar core. There are some 30 million stars in the central bulge. There are some 30 million stars within the bar core. Star density drops dramatically as you leave the central bulge. By the time you get to around 325 ly, the density has dropped to around 3 stars per cubic light year. These are all rough estimates. It is hard to get a good reading of the center due to all the dust clouds in the way.
Love your channel and have been an avid follower - I keep coming back to some of these videos to get a clearer understanding of the fundamentals that is so well articulated by you - thanks David your are my online Astro Prof !!
We pick areas of space near the center of the galaxy and work our way out to the edges. At each distance from the center, we count the number of stars in a small volume. This gives us a star density. The star density is very large near the galactic core, thins out as we move out to the edge. We then multiply each density so calculated time the actual volume of space in each galactic region. I think the total as of our current count is closer to 600 billion.
David I have 2 words to sum up ur you tube film and I hope u don't mind me saying this....... absolutely brilliant!!! I enjoyed every minute of it, even tho I sort of knew/heard of it in past podcasts etc it was done so anyone could understand and that's what it's about, appealing to everyone so well done and please, don't stop!!!!! Thanks.
Andromeda has a trillion stars. There are 250,000 trillion stars within 1 billion light years from us. In fact, there are more stars in the Universe than there are grains of sand on all the beaches of Earth. It’s a wonder to ponder.
David- I watch as many videos on space as people put out there and I can find the time to look at them. I always come back to yours for clarity, logical separation of topic and the music in the background I the perfect touch. When I'm done I feel as though I've really learned something. I don't know how your mind can understand the complexity of the equations and their application but for a brief moment or two after your wonderful videos I feel as though I understand perfectly. Maybe if I just watch them over and over some of the good stuff will stick. If only our president would watch he might realize what true intelligence really is!
Thank you David for an extreamly nice and interesting description of our place in this universe and the conditions valid for our galaxie, the Milky way.
Excellent vídeo and better explanation. The use of classical music give a touch of beauty to the scene. Complex astrophysical concepts explain with simplicity. Thank you for your work!.
Thank you so much!! you explain it so simply even for non-native english speakers! best videos on the astronomy, they explain even better than bbc/etc films! really helpful ;)
Very informative video with simple calculation which are appreciated. I suggest you to use km instead of miles like other space videos. There is a reason why International System of Units (SI) are used. Thanks.
Despite shortcomings, big thumbs up for the amount of information and how it was presented in a cohesive and easy to understand fashion. Awe-inspiring.
Before going to sleep,i srart one of your video and gradually fall in sleep by hearing the story of travelling through the mysterious and wonderful universe.
Thank you Mr. David Butler. First time I watch this video many many times that it's explained very clearly about the Milky Way galaxy, our sun is located in the Orion Spur (3500 light years across, 2000 light years deep and approximately 10,000 light years long) and other neighbour stars of our sun nearby. This video that give us a extremely view of our Milky Way galaxy.
Excellent... Thank you ..; A video about the Soar system in the Milkyway , its orientation , movement around the milkyway center...etc will be very informative. Thank you
I can't get my head around how the "Goddard Space Flight Centre's Cosmic Background Explorer" (catchy name...) could have captured that 'edge view' image
READ MY LIPS PEOPLE OF THE EARTH, THIS IS OUR CREATOR Then from the throne, there poured a great radiance, surrounding and lifting my soul by its power. Swiftly I moved through the spaces of Heaven, shown was I the mystery of mysteries, shown the Secret heart of the Cosmos.
It's very humbling to think all of the stars you can see in the sky are in just a tiny, tiny section of the Milky Way. Just imagine what the night time sky would look on a planet near the center of the galaxy
The Perseus arm averages around 1,000 light years thick. On your previous question, I said 600 billion stars, but that number includes a guess as to the number of brown dwarfs that might exist. The more conservative number is 400 billion.
I am in fourth grade and I find it very helpful to know this stuff especially if there is a test on it.we have also been learning about galaxies,the planets,gravitational pull and a whole bunch more things.so thank you!

You have a very interesting series ,I just stumbled upon and I am glad I did it has taught me so much already, I like most people began my love affair with astronomy by watching cosmos by Carl Sagan back in the early 80's PBS I have always watch and read everything I can on the cosmos I'm interested to know what you thoughts of the new Cosmos ? I found your series and am still finding it very educational to me it has answered many questions that I have had. I think that you are a very smart man to know all these things that you know. Thank you for sharing this information I'm curious also do you believe there is other technologically advanced civilization in the cosmos ?
Thank you David for attempting to methodically explain the structure of our Galaxy. It’s difficult to conceive spatial understanding on this enormous scale but your description and reasoning makes it possible. I note a few negative comments herein about the style of your presentation and can only assume those commentators haven’t grasped the message and prefer, instead to inanely concentrate on points of irrelevant criticism. Gladly totally ignored. Well done 👍
true, eventually all galaxies will be eaten by black holes and the black holes will probably collide and consume each other. 0 life. then they explode or some shit and it all starts over.
This is not the likely outcome. Based on current observations, the black holes will move farther and farther apart and eventually they will slowly die from Hawking radiation. They will not "collide or explode or some shit"

Me too Steve Rafferty. I am still in a state of shock and joy at finding this site, and watching David go thru that awesome explanation of our universe. Some are attempting to be-little David's work, by homing in on all the misspelled words, but there will always be short-sighted brains so willing to exalt themselves by splitting hairs over the small stuff.
SO the cosmic background explorer was launched about 170,000 years ago was it ( at near light speed). Or did I miss the invention of time travel and folded space worm holes while on holiday on Andromeda ( must be if sent out in 1990) ? Or is this some alternate reality and it proves the many world theory, I must be lost in time/space I think!
The cosmic background explorer is part of my next video on cosmology. It was not part of the Milky Way Galaxy story. Where in the video did you see reference to it?
Just a note - a zero volume in such curved space time does not make any sense. From our point of view it may appears as zero volume, but looking inside this region it could be entire new universe.
Yes, relativity and quantum mechanics give different pictures of what is inside the event horizon. We know that it is impossible to go in and find out observational. SO, officially, no one knows what is inside the event horizon, and until we can unify the physics, we don't know.
I enjoyed that, particularly the way you explained how we cannot see through the centre of the galaxy and must estimate what lies beyond. I feel that the key to understanding all this is that there is no such thing as an object, its just a combination of atoms and atoms are mostly empty space. The atoms we see on the earth's surface are not under any compression and are at their fully expanded size, when compressed they fit into smaller spaces. I don't understand how the electro magnetic forces survive under such conditions.
Holy Quran Chapter Yasin 36 verse 38 : "And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing." verse 40 : "It is not allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming."
wow ive heard once we are in an arm at the edge of the galaxy , but we are really in the middle between the galactic centre and the edge, theoretically some other solar Systems with live should be all around us . this was really informativ to update my view where we live in the milky way
11:40 - 12:27 So it seems like 2 black holes of almost same gravity spiraling a higher gravity black hole (I'm assuming Sagi A). What are the cluster of stars called of the beginning of the Perseus Arm and Scutum Centaurus Arm called?
I really don't think we as humans will never comprehend the understanding or technical workings of intergalactic space??, we were never designed as a species to understand the immense scale of the quantum universe or physical or should I say observable universe. It is mind boggling and strangely addictive to want to explore our perceived reality. Thankyou science,, PEACE ✌
I've been thinking alot lately about the effects on our solar system as we are essentially traveling within the galaxy. I think it's an interesting theory that solar cycles, and earth magnetic reversals, etc..could relate to our position in our galaxy. there could be positions more favorable than others, impacting the gravitational effects and so on...
+Pradip Kumar well, if we agree that someone has created that "genius" who created all that, the basic question will remain the same. There must be someone who, created each and every thing and, was not created by anyone.
Well, keep your religious books aside and think logically..Why do you think universe need creation?? One reason could be you believe that nothing can be created without a higher intervention no?? By that logic these must be someone who might have created god first to create conceive that plan..that leads to something can exist without intervention....what if Universe happened on its own..no body created it. To undertand this u have to throw your religious text written by some ignorant ppl of medieval age.
+Pradip Kumar I never mention any religious book/quote to uphold my point. nor i wanna drag religion into it. All I have is some logical questions that needs logical answers not from any Holy Scriptures! To me believing that the so perfect and calculated universe can come into being without any creator is actually believing that a Bullet Train engine is coming out of a hardware shop without any engineer.
Great videos - best on the web ! One question if you have time -- why don’t the moons of planets get pulled in by gravity to the point where they come crashing in? Thank you sir.
The moons have what we call orbital velocity. If they slowed down, they would be pulled into their planets. But there is nothing out there to slow them down.
@@howfarawayisit Thank you for responding. Now this begs the question - Do you happen to know how tight of a relationship say our earth to the moon is regarding orbital velocity. What I mean is could the moon exist where it is if it was any faster or slower by X amount. And if that is a precise speed, how remarkable is it that moons exist anywhere being that they need to reach that perfect speed as they are forming around the planet. Sorry to go on long like that. Thank you sir. window
@@Goodtimes523 If it were slower it would orbit closer. If it was so slow, that it did not have an orbital velocity at all, it would fall to Earth. If it were faster, it would orbit further away. If it was so fast that it had escape velocity, it would leave the system forever.
Just remember there are two scales: Short and Long scales (SS & LS). North America, UK, Brazil and Asia uses the Short Scale, thus 300,000 trillon kilometers (SS). But Continental Europe and Latin America except Brazil uses the Long Scale, therefore we have 300.000 billion kilometers (LS) or 0,3 trillon kilometers (LS), with periods to mark thousands instead of commas, and commas to mark decimal figures. 1 trillon (SS) = 1 billon (LS) = 10^12 en.wikipedia.org/wiki/Long_and_short_scales en.wikipedia.org/wiki/Decimal_separator
I suggest you use km/s instead of miles/hour. The reason is that the velocities are small numbers if you use those units and that is easier to remember and to compare with c. In my theory, this velocity should be comparable with the Hubble expected velocity at that position. 100,000 Miles/hour=44.7 km/s This implies a Hubble distance of 44.7=c/R_0*d or d=44.7/300,000*13.8E9=2E6 ly. That would be the distance if there were no extra gravitational attraction.
@@howfarawayisit Since I have your momentary attention, please take a close look at the 3D map of the Universe at the moment the densities froze. qsnyc.shinyapps.io/UniverseMap/?_ga=2.113960967.1865578647.1602546909-1505942256.1600516222 I don't have the knowledge in astronomy to fully evaluate if this data is consistent with observations. Notice that this is the seeding distribution (missing the high-frequency Poison noise) and perhaps not perfectly oriented. In the second tab, you can see how the plot for layer 108 should look like. That was created in python. My plotting in R is still improving and there might be not only a loss in resolution but also a rotation. I had to move from celestial coordinates to Lattitude and Longitude. I know that there is a parameter to define the direction of the North Pole in the plotting command. I still have to think about that. So, the map might still improve. That said, you might be able to recognize astronomical features already.

+David Butler No, the only science class I took back in high school was Biology. Just interested in astronomy, the cosmos etc. Videos such as yours are a great learning resource for scientifically illiterate minds such as myself haha.
I wonder what we'll se when we get to the other side of the blind spot. Another galaxy 1/10th the distance of Andromeda would be cool. I'm counting the years...
Thanks. I did a wholesale update of all the videos in the video book to improve the sound. Can you take a look at the updated version (identified in the title) and let me know if you think it is better (ore not).
You're referring to the diameter of the disk. And indeed any number plus or minus 20% would be in the ballpark. We'll learn more from the new space telescope Gaia. Take a look at the 2013 update video if you haven/t already.
How the hell can you take a pic of the entire galaxy when we are in it. That would be like taking a picture of the outside of your house from inside the house
No, I stopped watching at 13:00. I did continue watching after your message, but it is too confusing for me? I am not sure what his point is? Can you explain in a few words what the point is? Thanks.
if you take enough pictures of the inside of your house, then yes, if you know what you are doing you can put together a very accurate picture of what it looks like (structurally) from the outside. think things out, dude.

I feel that the key to understanding all this is that there is no such thing as an object, its just a combination of atoms and atoms are mostly empty space. The atoms we see on the earth's surface are not under any compression and are at their fully expanded size, when compressed they fit into smaller spaces. I don't understand how the electro magnetic forces survive under such conditions.

I want more And more information about our universe..... Some thing more interesting and unbelievable incidents.. Etc
wow ive heard once we are in an arm at the edge of the galaxy , but we are really in the middle between the galactic centre and the edge, theoretically some other solar Systems with live should be all around us . this was really informativ to update my view where we live in the milky way
Edwin Hubbel's chief assistant, Halton Arp, demonstrated that black holes are imaginary. Read his book "Seeing Red".
Would you post this on the howfarawayisit wiki for further discussions? howfarawayisit.fandom.com/f Thanks.
11:40 - 12:27 So it seems like 2 black holes of almost same gravity spiraling a higher gravity black hole (I'm assuming Sagi A). What are the cluster of stars called of the beginning of the Perseus Arm and Scutum Centaurus Arm called?
I really don't think we as humans will never comprehend the understanding or technical workings of intergalactic space??, we were never designed as a species to understand the immense scale of the quantum universe or physical or should I say observable universe. It is mind boggling and strangely addictive to want to explore our perceived reality.
Thankyou science,,
PEACE ✌
I've been thinking alot lately about the effects on our solar system as we are essentially traveling within the galaxy. I think it's an interesting theory that solar cycles, and earth magnetic reversals, etc..could relate to our position in our galaxy. there could be positions more favorable than others, impacting the gravitational effects and so on...
when I see such VDOs, I wonder who could have created all that??? so calculated universe cannot come into existence without any creator.
I know it's such a beautiful universe
Well I also wonder who Created that Creator who has such a genius mind..Some must have created him no?
+Pradip Kumar
well, if we agree that someone has created that "genius" who created all that, the basic question will remain the same. There must be someone who, created each and every thing and, was not created by anyone.
Well, keep your religious books aside and think logically..Why do you think universe need creation?? One reason could be you believe that nothing can be created without a higher intervention no??
By that logic these must be someone who might have created god first to create conceive that plan..that leads to something can exist without intervention....what if Universe happened on its own..no body created it. To undertand this u have to throw your religious text written by some ignorant ppl of medieval age.
+Pradip Kumar
I never mention any religious book/quote to uphold my point. nor i wanna drag religion into it.
All I have is some logical questions that needs logical answers not from any Holy Scriptures!
To me believing that the so perfect and calculated universe can come into being without any creator is actually believing that a Bullet Train engine is coming out of a hardware shop without any engineer.
Aren't we in the Milky Way Galaxy?
Copernicus put the sun at the centre of our solar system about 400 years ago, not 1500 years ago. You may add an annotation as correction.
+Manish Udar Done. Thanks.
Actually, Greek astronomer Aristarchus in the 300s BC maintained that the earth revolved around the Sun.
Very cool
I believe I got this picture and text from the European Southern Observatory. Google GigaGalaxy Zoom.
Great videos - best on the web ! One question if you have time -- why don’t the moons of planets get pulled in by gravity to the point where they come crashing in? Thank you sir.
The moons have what we call orbital velocity. If they slowed down, they would be pulled into their planets. But there is nothing out there to slow them down.
@@howfarawayisit Thank you for responding. Now this begs the question - Do you happen to know how tight of a relationship say our earth to the moon is regarding orbital velocity. What I mean is could the moon exist where it is if it was any faster or slower by X amount. And if that is a precise speed, how remarkable is it that moons exist anywhere being that they need to reach that perfect speed as they are forming around the planet. Sorry to go on long like that. Thank you sir.

@@Goodtimes523 If it were slower it would orbit closer. If it was so slow, that it did not have an orbital velocity at all, it would fall to Earth. If it were faster, it would orbit further away. If it was so fast that it had escape velocity, it would leave the system forever.
It has a similar electric Charge.
Just remember there are two scales: Short and Long scales (SS & LS). North America, UK, Brazil and Asia uses the Short Scale, thus 300,000 trillon kilometers (SS). But Continental Europe and Latin America except Brazil uses the Long Scale, therefore we have 300.000 billion kilometers (LS) or 0,3 trillon kilometers (LS), with periods to mark thousands instead of commas, and commas to mark decimal figures.
1 trillon (SS) = 1 billon (LS) = 10^12

I suggest you use km/s instead of miles/hour. The reason is that the velocities are small numbers if you use those units and that is easier to remember and to compare with c. In my theory, this velocity should be comparable with the Hubble expected velocity at that position.
100,000 Miles/hour=44.7 km/s This implies a Hubble distance of 44.7=c/R_0*d or d=44.7/300,000*13.8E9=2E6 ly.
That would be the distance if there were no extra gravitational attraction.
I do in the updated version.
@@howfarawayisit Since I have your momentary attention, please take a close look at the 3D map of the Universe at the moment the densities froze.

I don't have the knowledge in astronomy to fully evaluate if this data is consistent with observations.
Notice that this is the seeding distribution (missing the high-frequency Poison noise) and perhaps not perfectly oriented.
In the second tab, you can see how the plot for layer 108 should look like. That was created in python. My plotting in R is still improving and there might be not only a loss in resolution but also a rotation.
I had to move from celestial coordinates to Lattitude and Longitude. I know that there is a parameter to define the direction of the North Pole in the plotting command. I still have to think about that.
So, the map might still improve.
That said, you might be able to recognize astronomical features already.
@@howfarawayisit Notice that the slider Layer actually change Redshift

Please upvote the posting such that I can overcome censorship.
My work has been published in books and low visibility journals and censored in mainstream journals and arxive since 2005.
@@howfarawayisit By the way, in the past I provided arxive a published article (in peer-reviewed books and journals) and two endorsers (one being the chairman of the Department of Mathematics at Rutgers).
The article posting at Arxives was denied under the guise of "uninformed endorsement" without any other information. The first time, they just first accepted and then a half-hour later wrote back: INAPPROPRIATE

Dear Dr Pereira,
Thank you very much for having submitted your manuscript entitled :
"Hypergeometrical Universe Theory Supernovae High Z Predictions"
to Astronomy and Astrophysics.
I regret to inform you that your manuscript cannot be considered for publication in Astronomy and Astrophysics because we do not publish articles that are not authored by members of astronomical research institutes.
Sincerely,
Thierry Forveille
A&A Editor in Chief
#########################
Other journals just took the article out from the peer-review process and refused to give a reason for that. That is what I call censorship
Dr. Forveille just told me that they don't publish articles from anyone that does not belong to the club...:)
It couldn't be any more shameless...:)
I need a strong endorser because the endorser cannot fear Paul Ginsparg. Will you endorse me or consider doing so?
I've never heard an estimate of the number of stars within the Milky Way galaxy to be 600 billion. I thought it was between 200-400 billion stars.
+Alex Jordan You are correct. I have fixed the error via annotations.
+David Butler thanks for the reply. Really enjoy your series of videos!
I'm glad. Are you a physics student?
+David Butler No, the only science class I took back in high school was Biology. Just interested in astronomy, the cosmos etc. Videos such as yours are a great learning resource for scientifically illiterate minds such as myself haha.
+David Butler hi
Amazing human being for discovery of such a amazing thing.
the milky way galaxy is about as far away as you are from the chair you are sitting in
It's not that far.
I wonder what we'll se when we get to the other side of the blind spot. Another galaxy 1/10th the distance of Andromeda would be cool. I'm counting the years...
We'll get a good look in about 115 million years.
Love the video. The music is a little distracting though. I would personally prefer it to be turned down at least 50%.
Thanks. I did a wholesale update of all the videos in the video book to improve the sound. Can you take a look at the updated version (identified in the title) and let me know if you think it is better (ore not).
I've read somewhere that our galaxy is probably a bit wider than 100,000 light years. I've heard between 100,000-120,000 ly.
You're referring to the diameter of the disk. And indeed any number plus or minus 20% would be in the ballpark. We'll learn more from the new space telescope Gaia. Take a look at the 2013 update video if you haven/t already.
I wonder what's inside our Milky Way's galactic center.
fudge
In a center of every Galaxy is a Black Hole
creamy nougat, everybody knows that.
Serge and its name is Oparah
How the hell can you take a pic of the entire galaxy when we are in it. That would be like taking a picture of the outside of your house from inside the house
That is exactly what I thought. You would have to travel millions of light years out of our galaxy to get those shots.
No, I stopped watching at 13:00. I did continue watching after your message, but it is too confusing for me? I am not sure what his point is? Can you explain in a few words what the point is? Thanks.
That's what I thought. Thank you.
Ever heard of CGI?
if you take enough pictures of the inside of your house, then yes, if you know what you are doing you can put together a very accurate picture of what it looks like (structurally) from the outside. think things out, dude.
