David Butler, you rock! I find your calm descriptions of these cosmic things calming and meditative, as well as elucidating. You are a true educator! Thank you very much for your efforts!
Funny, I have to watch it at 2X speed to keep from getting annoyed waiting and waiting for the next idea. I feel as if the story is deliberately s l o o o o o w to be able to fit more adverts.... put down the qualudes, have a triple espresso with a side of amphetamine, wash it all down with a Jolt cola and pick up the pace! PBS Space Time goes fast, that is why we have a pause button.
Awesome video, as always. No other presentation conveys the sense of wonder and unimaginable distances and size of the universe. (And the music is perfect too) Thanks for posting!
The light takes that long to get here in our terms but to a photon it's instant as time stops at the speed of light relative to us. So many crazy things to get your head round, I love it and hate it at the same time.
Thank you VERY MUCH for this series of lectures. I'm not an astronomer - not even very interested in such thngs - but you've given me a MAJOR insight on the subject and instilled me with the HUNGER FOR MORE. My 8 y.o. daughter, which loves hearing about black holes, was thrilled by some of your images (as was I too!). Thanks, again.
I enjoyed this series. I learnt a lot of interesting precise details, and it was never too difficult . Thank you, sir, and your voice and the classical music were a real soothing pleasure.
This may seem strange to some people, but the vastness of the universe, and my seeming insignificance is actually empowering. If all of it "doesn't matter so much", then what's holding me back? who cares? go for things with no fear, no regret. Did anyone else get sort of the same thought after seeing superclusters become a dot?
From the first time I saw it, I've been amazed at how much the large-scale structure revealed by the Sloan survey resembles a neural network. The processes involved in their formation are obviously vastly different, but I can't help but wonder if this is perhaps indicative of something fundamental about the way complexity forms at all scales.
Self similarity can be seen everywhere. Take The mind and a lightning storm in a hurricane, we observe the calm of consciousness, in the "eye of the storm" while torrents of chaos and electrochemistry surround it. The emergent properties of existence. What it all emerges *from*. We shall all maybe know, someday.
I want to thank you for your videos good sir. You must be the most patient man to amass all of this data and presented as such. But most impressively, put up with this comment section :)
Unlike poor Chris below I find your voice soothing, your presentations incredibly interesting and your obvious knowledge on the subjects impressive. For every Chris out there hearing "meth mouth" (?) there's at least a hundred of me.
There are estimated to be 1,000,000,000,000,000,000,000,000 planets in our observable Universe. Add in a possible multiverse with zillions and billions and trillions more planets, I’m afraid that makes us pretty insignificant. I’m totally cool with that, it’s still wonderful.
With all the money spent on War/politics, if we'd put ALL that money and time in to space exploration, imagine what we could see now, what new technologies for space exploration would be around.
Oh my, you did manage to correct IC1101. I saw that mistake in another video just recently. Wonder how that started but one gets to see who is watching who. I didn't think this series could get any better but the newer version and the optics on my new computer are breathtaking. Thank you, David.
Far away = long ago. When we look at a distant galaxy, we aren't seeing it as it is 'now' but as it was when the light our instruments detect was emitted. So the Hubble ultra deep field proves that those galaxies in it were already billions of light years away from the space we now occupy at the time their light we see now was emitted.
Your videos are truly excellent. I really enjoy them and learn some interesting things to boot. Thank you for making them. This is my favorite vid so far. I only wish there was a way to represent the observable universe in such a way as to truly grasp the dimensions of it all. Distances in millions of light years sound big, but how do you picture something like that in a frame of reference that really means something. Pictures of skyscrapers compared to each other are easy to grasp the scale of the objects. But that last rotating simulation of the universe.. how can anyone truly grasp that kind of scale, when there is literally nothing you could compare it to at that size? I love thinking about it though, and love these videos!
Fantastic. These video's are Encyclopeadic for the wealth of information contained within them. Thank you Sir for taking the effort and time to produce them in such high-quality. I eagerly await the launch and deployment of the JWST in 2018!
Space is unbelievably big. The distance to our sun is almost 100 million miles and the solar system extends over 120 times that length and that's conservative. You then have the hypothetical oort cloud. And that's just the solar system. The nearest star, A Centauri, is 40 trillion miles away (roughly), and there are around 300 billion stars in the milky way. And this is one galaxy. There are at least 100 billion more. What is life.
What an excellent series. I thank you so much David Butler. The only subject I wish had received a good deal more attention was the Oort Cloud -- if you decide to do one more main video. :-)
David Butler Wonderful. I'm subscribed and will watch for it. Your presentations are excellent. BTW, if you haven't discovered her yet, Professor Carolin Crawford of Gresham College has a whole series of simply outstanding lectures I'm sure you would appreciate. Search her name on RUclips.
A lovely ending quote from Edwin Hubble. But personally, I prefer the deeply profound poetry of Douglas Adams.: *_"Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space."_*
_Pip pip, tallyho and mind the tweed suit!!_ Yes, tales of his obsession with all things English (Anglophelia?? Anglomania?? LOL) are legendary. Clearly a man who believed an accident of birth placed him in the wrong culture and country.
it's really simple.. The universe is expanding because the Dev's have to expand the Render Distance to avoid Server lag/ overload. or possibly, someone found an rng exploit and that's the only way to patch it ; )
im not the first to suggest that over a very long distance, space time being curved, not sure that curve is linear but if so, as we look back in time farther and farther out, this may mean we are actually viewing a part of the universe close to our local group as it was earlier in time. Light is at all points all at once. if you were to travel at the speed of time, time stops for you but to an observer goes by as his pace. but this is not what we see as an observer for light. hard to make sense when 2 different realities exist.
There is a small piece of music that's sounds like "All By Myself" 6:16- 6:44 being a musician I instantly was drawn to the choice of notes that belongs to the song. I always liked that song.
I also wonder, if the Hubble Ultra Deep field image, was taken over 11 days, what would be seen if you aimed it at a region for 20 or even 30+ days! Also, imagine the trajectory line of the Hubble telescope was the same trajectory as an alien ship going towards or away from us, what if anything we would see!?!? An exo-galactic cruise ship, like in The Fifth Element, maybe coming here to observe though strange, noise-making primates! :D ""Aah Glip-Glop darling look, those furless monkeys have made a crude telescope-like device to look at us! Maybe we can teach them basic space-sign language; will have to basic though, they only have 5 digits on their only 2 arms!!""
the size of the galaxy is 2 million light years across, just take a minute to think about the absurd size of that, and yet we cant see it without powerful telescopes
As space is expanding, more space is getting created to fill in there- such that the density (technically, vacuum energy density) of space always remains same. Going by conservation laws, even space itself is a manifestation of some thing (a form of energy or field), not same as 'nothing'. Vacuum is only a false vacuum (a local minima only). But globally, it could degenerate into further lower energy state.
Unfortunately, I cant seem to find a map of all the nearby filaments beyond our local superclusters. I only found maps of the superclusters in our local superclusters and the clusters in the Virgo Supercluster, and not the filaments in our universe! Was really hoping to find a labelled observable universe map. As far as I know, there are only three filaments in the universe: Pisces cetus, Sloan great wall, and Hercules-Corona borealis great wall. Please let me know if you found any maps. Thanks again.
Love your channel, thanks for your mind-blowing contributions. A couple of silly questions though: gravity is a strange beast, it seems to be doing work without consuming or requiring energy. No matter seems to be converted into energy when our sun attracts the planets.. unless it's part of the fusion process, but in that case, what is attracting me to the Earth's crust? What goes on in the nucleus? Does that mean that once the nucleus is no longer active, Earth's gravity will disappear? We have never seen a system where gravity does not exist because the system itself "ran out of fuel" to attract stuff around it so to speak. Nowadays we have many many stars and galaxies to look at but nobody ever found anything of the sort. I may be missing something as far as General Relativity is concerned but all these attractive or repulsive forces should be accounted for energetically... conservation of energy should be one of the universal laws. Plus gravity seems to be going in the opposite direction with respect to the laws of thermodynamics naturally favoring order to disorder. Sorry for the stupid question but I could not wrap my mind around it.
Where did you ever get the impression that I even wanted to build a time machine? The physics don't work so I gave up. Speeds greater than light work out to give imaginary properties, no negative time progression.
it sounded as though you were working on something spectacular Dan.. I was hoping to get ahead of you on building the proper flux capacitance to allow enough ac current to ground of the device being propelled along the space time curve. you see, i have been working on this problem for the last 22 years and i think with nanotechnology we here at The Lab, have come very close to finding a conductor with absolute zero resistance as you see, there cant be any, if there is the 220 gigawatts needed to envelope the transport vehicle cannot be properly distributed from our flux array. good day
Because the future, by definition, has not happened yet. We can only project the future in our minds, based on the knowledge of past events. Human beings are fairly proficient at spotting patterns and this is what we falsely use to predict the future- and we are almost always wrong.
So, when we say it is x light years away, is that where the light currently appears to be or is it where the object is suspected to be at this time, considering movement and space expansion?
David could you elaborate on what you say at 17.20 on the conservation of energy laws please? From my (extremely limited) understanding, the expanding universe is consistent with the entropy law. I've never studied physics formally & would love a clearer explanation here. Thanks, Ross. Also, great videos, really loving them. Will share with all my friends.
I'm glad you like the channel. On the conservation of energy question, I think it is just about the fact the the light looses energy as it passes through the expanding space.
I see, so it goes against the 1st law. I've been reading up on the Great Attractor. Do you know much about it? I watched a video with Somak Raychaudhury (who did his PhD on it) - seemed to reckon it doesn't exist. Fascinating science though
Why do people comment here about the mistakes on the video? You can just send an email to mr. Butler. If you can't do half of what he did with this videos, do not publicly criticize. The whole series is really amazing, but for for thinking out what the cosmic web is I'm speechless.
Are you confusing IC-1011 with IC-1101? IC-1011 is a barred spiral galaxy, IC-1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies.
Hello, I love your videos and explanations. I believe you don't have (I apologize if you do) a video about the shape of the universe, the isotropic and homogeneus subjects related, and the cosmic microwave background. I do have some theoretical background on astronomy, but I've never really understood these concepts. Is there a limit on how far you can see into the universe? Also, is there something like a 'big bang point' from which you would see matter being expelled? Thanks!
+Imana Maiwaga I touch on this a bit in the segment on the Cosmos. But to do it justice, I'm putting it into my next video book "How old is it" scheduled for a piecemeal delivery starting later this year.
Seems to me, H0 may not have been a constant throughout universe's history. Like you pointed out in explaining SN 2002dd. Universe then could be older.
Dr. Buttler, my hobby is astronomy, i want to keep all the videos in series how can i get it? some of videos you have uploaded are not opening. how can i get all?
+Xi Zhang Yes, and it was everywhere. If you think of the surface of the expanding balloon, you'll note that its expansion doesn't have a point of origin on the surface itself. Picturing the 4D space-time equivalent isn't easy to do, but the idea holds up - I think.

David, Thank you. OUTSTANDING JOB, I have always enjoyed this subject but you made it easy to understand and enormously interesting. NO, SUPER JOB!
always good to remind yourself about how insignificant you really are in the universe
we are not insignificant, we are precisious and valueble
There are estimated to be 1,000,000,000,000,000,000,000,000 planets in our observable Universe. Add in a possible multiverse with zillions and billions and trillions more planets, I’m afraid that makes us pretty insignificant. I’m totally cool with that, it’s still wonderful.
But isn't that the beauty of it? At least from our perspective in significance.. we are the most relevant, and irrelevant existence, at the same time.
True, on the other hand, the human brain is still the most complex thing we have ever discovered big or small.
Sir I commend you for such awesome and highly enlightening videos...

This segment 05:50 to 07:30 just blew my mind entirely.
im not the first to suggest that over a very long distance, space time being curved, not sure that curve is linear but if so, as we look back in time farther and farther out, this may mean we are actually viewing a part of the universe close to our local group as it was earlier in time.

“Joe Pera talks to you about space”
How does one determine which direction in time one is looking?
Can we not look forward any at all?
we can't see into the future. we can only see into the past.
Because the future, by definition, has not happened yet. We can only project the future in our minds, based on the knowledge of past events. Human beings are fairly proficient at spotting patterns and this is what we falsely use to predict the future- and we are almost always wrong.
So, when we say it is x light years away, is that where the light currently appears to be or is it where the object is suspected to be at this time, considering movement and space expansion?

two thousand. ....MILLIONN. years ....wow
Are you confusing IC-1011 with IC-1101? IC-1011 is a barred spiral galaxy, IC-1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies.
James Prince I am pretty sure this is the case
Hello, I love your videos and explanations. I believe you don't have (I apologize if you do) a video about the shape of the universe, the isotropic and homogeneus subjects related, and the cosmic microwave background. I do have some theoretical background on astronomy, but I've never really understood these concepts. Is there a limit on how far you can see into the universe? Also, is there something like a 'big bang point' from which you would see matter being expelled?
Thanks!
+Imana Maiwaga I touch on this a bit in the segment on the Cosmos. But to do it justice, I'm putting it into my next video book "How old is it" scheduled for a piecemeal delivery starting later this year.
David Butler Ooh okay, thanks!
Seems to me, H0 may not have been a constant throughout universe's history. Like you pointed out in explaining SN 2002dd. Universe then could be older.
+Diptendu Roy Chowdhury Indeed. I think we're in for some surprises in this area.
Dr. Buttler, my hobby is astronomy, i want to keep all the videos in series how can i get it? some of videos you have uploaded are not opening. how can i get all?
All my videos should show in all countries. What is it that you can't open and watch?
Awesome !!!!
so IC 1011 might be gone now? or vastly different? a billion years of change!
Thank you Sir. if we measure the movement and speed of all the visible objects in cosmos, can we find the location of the big bang?
+Xi Zhang Yes, and it was everywhere. If you think of the surface of the expanding balloon, you'll note that its expansion doesn't have a point of origin on the surface itself. Picturing the 4D space-time equivalent isn't easy to do, but the idea holds up - I think.
Thank you very much
