Mr Butler, your work is beautiful. I am hooked to your channel. The simulation of the colliding galaxies brought tears to my eyes. Intergalactic poetry

The fact that you have had the courage and intellectual honesty to explain the possible flaws in the hubble constant and show the example of NGC 7603 makes me respect you so much more. Love your videos and great work

I see it as two happy family's coming together after an eternity apart, a time for cosmic celebration :-) Wonderful imagery and narration, thank you David :-)

Nature do most beautiful things. Thank you for this and all lectures. Love all your works.

Great videos David. Like old school documentaries, all the information you want presented in an interesting, detailed manner, without any silly melodramatic rubbish the subject doesn't need. Thanks.

This Video changed my life. towards the end @ 19:00 I started to cry, I can't believe we are able to see how galaxies collide! Something we won't be able to fully witness because of the time scale, but by seeing all these examples we can fathom what happens in our universe. I think James Webb is going to scare the poop out of us~

Hey David, When i see your videos, It just humbles me and makes me feel blessed that we have this life to live on this small planet inside this galaxy of ours. Galactic collisions are the life blood of the universe is what i have learned from this video. I have been hearing about this collision phenomena for quite some time but couldn't really understand the whole process. Now i do have a pretty good understanding. It's sad that our's is also headed for a collision in a few billion years from now.I also have read somewhere that nearly around a few billion years from now,the sun will end all life on earth because of surface temperature here on earth exceeding above 400°C or so because of the changes in the sun due to it's dying. So even if a collision happens ,there won't be anything left on this burning planet at that time which could see that, I guess. We should be truly blessed that we could observe and understand at-least this much even though it hasn't been too long ago that we started learning about these phenomena.It's also interesting to note some of the probabilities that are specified in the paper published by T. J. Cox and Abraham Loeb of Harvard-Smithsonian Center for Astrophysics about this collision between M31 and our galaxy such as the Sun being pushed out in to the outer halo region of the newly forming galaxy which they have named as (Milkomeda) or that our Sun getting ejected out of the disk of Milky way in to the tidal arms of the materials which will be thrown out of the Milky way. The ending of this video was just darn perfect. Could not have been better. Thanks very much for this. Eagerly waiting for the Voyager update from you.

Great educational videos that curb my curiosity about astronomy. As a non scientist (mech engineer) I am very fascinated with astronomy but regular science outlets just don't do it anymore. Thank you very much Mr. Butler

Thank you for this amazing series, I have watched it with true wonder and continually have had my mind blown by the size and beauty of these objects. Thank you for presenting it so well on youtube so we may watch it.

Galaxies are my favorite. It's still sinking in just how many have been discovered since the Hubble deep field images. It's just amazing!

Thanks David, I've watched several hours of your videos and intend to watch many more. I appreciate the demonstration of how to calculate the distance using the redshift.

Love your stuff Mr. Butler Glad you can present this to us

Thank You Mr. Butler. Have fallen in love with your videos.

This series is amazing! Best and most interesting job done on the subject so far!

What an awesome video, thanks for making these. Especially loved that simulation of the merging Milky Way + Andromeda. That was quite clever to show the simulation from different perspectives and comparing them to images of other known galactic mergers, loved it.

That NGC 7603 mystery blew my mind, I’ve never heard that before. I think I prefer the idea of a non expanding universe.

Your hard work is praiseworthy ❤️

Absolutely tremendous content in this and everything else you do David

Just imagine there is a planet similar to ours that support life. They're also researching if anything out in space could be communicated with. They are looking at the Milkyway Galaxy as a typical spiral galaxy that will eventually collide with Andromeda.

Absolutely Fascinating, Thank you Mr.Butler. 🇺🇸

The Hubble images have astonishing resolution considering the distance. I liked the space, fantasy, new age music in this episode, especially the one by Vangelis. Other people seem to be fans of classical, which works fine, because its complex, largely unrecognizable pattern sets it behind the speech on another level.

The distances, time, and forces involved in the interacting of galaxies is mind boggling and humbling. What is the span of human existence to the life of galaxies. All of our innovations and civilizations are less than an eye blink in comparison. And the life of an individual human is even less than that. Now take it even further and imagine interacting universes!

I've watched this series thus far; but, having seen this episode I am for some reason left very sad. The enormity of both space and time of the universe has left me feeling very insignificant.

If someone in the Middle Ages had fully understood the enormity and scale of the solar system, the distance just from the earth to the moon would have seemed unimaginable. And now we've sent probes out beyond the heliopause. With some sort of mechanism to provide constant acceleration or maybe taking advantage of wormholes, it's possible one day humans could travel between galaxies in a single human lifetime (it sounds ridiculous but due to general relativity it's completely true WITH a constant acceleration). Of course, by then we'll be AI's, but still it's cool to imagine.

But the song played the first minutes of this video and again from around 12 minutes into the video is from "Heaven and Hell, Pt 1" by Vangelis and Jon Anderson (ca 12:50 into that long track). It was also used in Carl Sagan's Cosmos in the 1980's.

Thank you thank you thank you, you’re videos are Amazing

My opinion is that not only is there more than one explanation for red shift but that the interpretation of redshift itself may need to be totally revise just based on NGC galaxies. Of course if that does happen a lot of things will go topsy turvey for astronomers and cosmologists.

The First time we could see you in the series ,I am a fan on universe,^_^

It kind of blows my mind how in reality (atleast relative to the size of the universe) how slow andromeda is moving towards us. It is moving at slightly over 100 kilometers a second, which in earth terms is incredibly fast, but at that speed it would still take 10 seconds for the andromeda Galaxy to go from me to my grandmas house.

If the universe is expanding equally in all directions, what causes two galaxies to merge together from two different directions?

Gravitationally bound systems stay bound even as space expands. You can think of it this way. Hold a pencil in your hand. The space between the pencil and the floor is expanding (as is all space everywhere). Now let go of the pencil. It falls to the floor even though the space is expanding. To see more about how this works, check out the "How Old Is It" video book.

well don't you have a interesting KZread channel 🖒 my friend you got a new subscriber keep up the good WORK

The time a fly takes to beat its wings one time compared with 1 year, is the the time of our insignificant lives compared with the time of Andromeda collision! So guys... relax!

Propably nothing. The distances between the Planets and Stars are too great. If humans still live they would have a beautiful night sky tho. But that's all there is, any civilisation at that time would only see milkdromeda and nothing else because all the other galaxys moved over the light horizon so no Hubble or whatsoever can detect any galaxy or stars outside milkdromeda - that means they will think that their galaxy is the only one in the vast space. Perhaps they could find our earth and find out about the milky way and everything else.

+IrrepressibleGuile Mr Irrepressible We determine distance via redshift with the understanding that the redshift has the one cause (i.e. the velocity of the receding object). If there is another cause, it could change our understanding about the size of the universe and the acceleration of its expansion. These two items are key to the reverse engineering that gave us the big bang.

@howfarawayisit

I think astronomers need to look into this more deeply. Accidental alignment is real, but some quasars might just be redshifting via a different mechanism. I'm wait to see more data myself. But a new reason for a redshift doesn't through out all existing redshift interpretations, it just requires more categorization of redshifts.

I like your presentation Sir

on the mystery of ngc 7603b red shift. i believe that astronomers fail to recognise that red shift is not only caused by a galaxy moving away, but also by energy production/higgs boson interaction. they not only move away, they also make atoms and light, both of which require space. kinda like a rocket in all directions but more like an open faucet.

I really enjoy and respect this series, Mr. Butler, and though I want to bring some things up about it, I do not want it to be taken as anything other than attempts at complementary criticism, a la science, etc. First, I have always wanted to see some far away object presentations with the statements around the actual times involved. So, for instance, if two colliding galaxies are 100 million light years away, it would be cool to hear, instead of 10 million years ahead, what will have happened 90 million light years ago, etc. I know this kind of time description is grammatically harder to construct, and I fear it may make it less interesting to others, but it would interest me. Second, in this case, I have recently read somewhere that now they believe Andromeda is actually smaller than the Milky Way. If I and the alleged astronomers are not wrong about this, it would be nice to see that simulation reformulated to the new scale. Thank you Mr. Butler for your very enjoyable and rewarding work in these videos.

Also your videos are wonderful.

Beautiful Mr. Butler. Stunning. I have one question, will the super massive black holes of Andromena and our own milky way merge? Is it a guarantee that all central super massive black holes of galaxies merging will ultimately form into one or are there exceptions? I watched all of your videos, thanks so much!

To look back I mowed a pair of eyes in to my back garden, that were visible from space; well you could see them on Google Earth anyway! If George Carlin's right and you get to go wherever you believe when you die!!! Send my mail here!! Just think how much of the universe is obscured, if you live somewhere between the two; that said, think of the night sky!!

I imagine other species marveling at the beauty of the galaxy that spawned them.

Eli, I'm glad you like the videos. I am not an astronomer. Take a look at the short 4 min video "How far away is it 01 - Preface". It explains who I am.

The simulation of the Andromeda-Milky Way collision at the end is something that I have never seen anywhere else. Where did you get it? I LOVE it!

I have a question, if time and space is expanding and galaxies are all moving away from each other, why are they some of them still colliding? I know I could be mixing up concepts myself.

5 Billion.....I can hardly wait" 😋⭐

What about the 2 supermassive black holes in each galaxy? They tend to collide

Couple of colliding questions. Are we able to see any changes in colliding galaxies if we compare imagery taken over, say, a 5 year period? It seems that for a time, the interaction is all based on gravity, and as approximation occurs, other forces take precedent. Radiation itself pushes matter around. I hope at some point you'll do a piece on the actual materials of these worlds, and what they were and what they become. You did cover some of this, showing how a double star explosion produces the materials needed for life. And just how the gases and dust collect to form stars considering their distribution really needs a program all it's own.
