While a lot of this was well researched, there were a few misinformed items that could lead to some viewers to come away from this not knowing the full picture: 2:04 - Galaxies do not spin like this. I know for animations sake, it’s a good analogy, but the spiral arms are not in fact real things but rather density waves of stars and dust that happen to be aligned in their orbit at the time that we view them! Incredibly pretty but not physical structures that orbit together 2:36 - Main sequence stars don’t only include the red to yellow dwarfs, but also the blue giants as well! The main sequence is defined as the region on the HR diagram (a diagram comparing color with luminosity of stars) where stars will live most of their lives, so blue giants actually do live on the main sequence until their death since it’s a line of stability, where the gravitational inward pressure and the thermal outward pressure due to fusion are equal 4:16 - Red giants don’t “explode” but rather shed their outer layer slowly through flashes of increased thermal energy of the core. The core does in fact shrink, but this does not cause an explosion, merely a “puff” 5:35 - I know this is just nit picking at this moment, but black holes shouldn’t have reflection spots on them. Artistic liberties should also be truthful! 6:18 - Pulsars do not rotate like this either. Much like the galaxies, I can see how the animation wouldn’t lend itself to a good estimation of the real world equivalent, but for a pulsar to rotate like this, it’s magnetic north would have to be 90 degrees opposite it’s rotational north. We see way more slightly off pulsars, where the pole spins around the axis of rotation incredibly fast, giving a pulse each time it lines up with earth 10:30 - Without dark matter, we would not “fly apart”. Gravity still would hold all the matter together regardless of dark matter’s existence, but we wouldn’t be spinning around the galactic center nearly as fast as we do. This is how dark matter was actually discovered, as all galaxies actually rotate near their edges with a speed that they shouldn’t have with normal keplarian orbits. 11:57 - The galaxies themselves are not “traveling faster than the speed of light” but rather the space between us and those galaxies are expanding faster. From Einstein, we know matter cannot travel as fast as light since it has mass, but the space in between dictated by dark energy doesn’t have to obey this law. All in all, very educational video! I’ve been a fan of yours since the science and mathematical maps you’ve made in the past (I’ve actually bought these maps for former teachers of mine as going away presents). Thank you for making these types of videos, and even though there were some errors in animation or specific wordings, the fact that I only wrote about so little speaks volumes on the research that went into this! -Random Internet Astrophysicist
I'll have to disagree with you on Dark Matter, the primary reason we know is because back in 1933 when looking at the Coma Cluster, the astronomer Fritz Zwicky noticed that the Gravitational Pull of all Observable Matter in the cluster only accounts for about 1% of what would actually be needed to keep the Galaxies Clustered together. This wasn't confirmed until 1970 though by Vera Rubin and W. Kent Ford, when they realized that the Mass of most galaxies only account's for 10% of what is actually needed to keep the star's in said galaxy orbiting the Center. Without Dark Matter, in our simulations even now, galaxies cannot form, and if you were to suddenly remove Dark Matter, they would scatter apart(Not fly apart but start to scatter slowly based on their own velocity).
You missed planetary rings, rogue planets and rogue stars And here are some potentially undiscovered and interesting things: - Quark stars - Thorne Zytkow objects - Dyson Spheres - Donut shaped planets or planetoids Since its only theoretical and we haven't discovered any of them it doesn't count I'd say. But since you broke things into categories you could maybe have mentioned peanut shaped astroids and astroid clusters/families I think that's a thing But overall absolutely awesome video! Great job! I'd love to show this to my friends and see if they even knew half of these objects
10:43 it does interact with ordinary matter it seems that it doesn't interact via electromagnetic interaction (that's why we don't see it) it certainly interacts gravitationaly (because insert example from the video here)
is anti matter dark matter? is anti gravity a property of anti matter? I mean if it's something we can't observe then it has to be something that repels light, right?
@@WinmanVideo no antimatter isnt dark matter, irc it's just like normal matter but has an opposite charge (i. e. Anti-electron has the same properties as normal electron but opposite charge)
Amazing video. I love how on a universal scale we just throw sized like "million", "trillion", etc around like they're nothing, while we as humans can bearly comprehend these big numbers beyond maybe billion.
Something that could’ve been touched on more are the voids in between galaxy superclusters. Specifically the Dipole Repeller which is a *huge* region of space that seems to be repelling galaxy clusters away from it and towards the Shapley supercluster, which is by far the largest galaxy supercluster we know. The fascinating part of all of this is it almost resembles a “magnetic pole” the way the galaxies seems to be moving. All of this was pretty decent stuff. This was a fantastic video regardless!

Spectacular video. Thank you so much. A few minor things I see: Small mistakes: 1) 2:34 Main sequence stars are not only Red, Orange and Yellow Dwarfs. There are also "Blue dwarfs" (O and B), not to be confused with blue giants, and "White main sequence stars" (A and F), not to be confused with white dwarfs. There are also "Wolf Rayet stars" (which are in the main sequence for very very little). 2) 1:15 It is Kuiper Belt not Keiper Belt. Expandind the "Solar System" part: 1) You mentioned "meteroids", but there are also "meteors" and "meteorites". They are further subdivided in chemical composition "Iron meteorites", "Pallasites", "Mesosiderites", "Chondrites", "Chondrites" and "Stony meteorites". All of these are even further subdivided in specific families (we think they come from the same ejection events in the Solar System's history). 2) There are populations of asteroids in the inner Solar Sytem not directly associated with the Asteroid Belt: "Apohele", "Atens", "Apollo" and "Amor" are all kinds of "Near-Earth Asteroids". There are "Trojan Asteroids" for Venus, Earth, Mars, Jupiter, Neptune and Uranus and they are divided in kinds depending if they are in the leading or trailing motion of the planet (in Jupiter you have the "Greeks" and the "Trojan Trojans") and there is also the "Hilda" population which is also in resonance with Jupiter. Asteroids can also be subdivided in dynamical cathegories called families: "Eunomia", "Eos", "Flora", "Koronis", "Vesta", "Nysa", "Themis" and at least 100 more identified families. 3) The outer Solar System asteroids and minor bodies are not only in the Kuiper Belt. For example, there are "Centaurs" (before the Kuiper Belt), "Scattered Disk objects" (which are overlapping and farther than the Kuiper Belt) and "Detached Objects" (which constitute the extended scattered disk and might go as far to overlap with the inner Oort Cloud). Kuiper Belt objects are divided in kinds like "Plutinos", "Cubewanos" etc... depending on their dynamical history. Detached Objects include "Sednoids" for example. All Kupier Belt, Scattered Disk and Detached Objects are called "Trans-Neptunian Objects" and for Detached and Oort cloud objects they are called "Extreme Trans-Neptunian Objects". 4) There are other structures in the Solar System that you haven't mentioned: "Planetary Rings", "Propellers" (found in Saturn for example), "Arcs" (found in Neptune for example), "Gas torus" (like the one created by Io or the one by Enceladus), "Meteor Streams" and interplanetary dust can also create some structures like the "Kordylewski Clouds" (found in the Earth-Moon system). 5) Moons in the Solar System are highly cathegorized in families. For Jupiter: "Galilean Moons", "Amalthea Group", "Himalia Group", "Ananke Group", "Carme Group", "Pasiphae Group" and other statellites which are independent of any group. For Saturn: "Inuit Group", "Gallic Group", "Norse Group", "Alkyonides Group"... And dynamically moons are classified in "Inner Moons", "Large Satellites", "Irregular Satellites", "Prograde", "Retrograde", "Co-orbital Moons" and "Ring Shepherds". 6) Comets have also dynamical kinds: "The Sungrazers" which include "Kreutz Sungrazers", "Meyer Group", "Kratch Group" and "Marsden Group". There are "Long period comets", "Short period comets" and "Hyperbolic Comets". There are "Binary Comets" aswell as "Binary Asteroids" also. 7) You mentioned the Heliosphere. In fact it is made of the combination of different structures with wildly different physical regimes where different phenomena are occurring: "Heliopause", "Bow shock", "Hydrogen Wall", "Termination Shock", "Heliotail" and "Heliosheath".
This is a very cool list, thanks for this! And good point about the blue dwarf, I should probably have included that in as well. It is always tricky to draw the line because each extra thing I add increases the time of the video. Thanks for the feedback, much appreciated!
@@domainofscience No, thank you for taking your time and be sucha good sport. This is anawesome video really. Making schemes for these is a crazy goal to archive and you have done it. Congratulations
I really really really like these videos of yours. Your efforts are appreciated. And the illustrations as well as the cohesive-ness are awesome. Thanks!
They aren't actually travelling through space faster than the speed light, but space itself keep expanding faster and faster, making the distance between us and them increase so that they get further away from us faster than the speed of light. Imagine two sharpie dots on the surface of a balloon that is being blown up, the dot's get father apart even though they are not moving. The ever expanding space between them is what we call dark energy.
@@domainofscience Thanks for responding, it's awesome to see interaction with viewers! So dark energy isn't pushing things through space, it's actually spreading out space itself? Without *moving* the space(-time)? But light still travels through the warped space-time at unwarped speeds, rather than being accelerated along with the matter? Shouldn't light be accelerated too as the expansion occurs? Thanks for replying, hope I'm not grilling too much.
@@calebhale9865 Hey no probs! Yes everything you just said is correct, and light doesn't accelerate, it actually gets stretched out to longer wavelengths so becomes red shifted as it sort of expands along with the space expanding.
This video is truly amazing! Thank you for this brilliant overview, it helped me a lot. I also like your illustrations, helps me to remember terms and concepts visually.
You are Incredible, Genius!! You have uploaded awesome videos which made me so curious to understand topics of Astronomy, Math, Physics, Chemistry, Biology and other stuff
The best description of all the universe that we had known till now... Waiting to see many more stuffs getting added as man could find the ways to travel beyond our galaxy🚀✨
For mystries, I wanted to see if you would put strange matter but sadly no, yet this is one of the best videos on space that I found so far, great job, was really surprised you remembered dark energy. keep up the good work
@@Vagabond-Cosmique I think galaxy filaments (or walls) have been known for a long time, but now they are discovering they they contain most of the dark matter of the universe.
Terrific video. 2 thoughts in response: 1. Have you thought about including the strange attractor regions of the universe? I feel like you skip quickly over the known structure of the universe beyond galaxies and galaxy clusters, and how they are structured/moving as well. Highly filamentous, etc. 2. You mention twice that the universe may/may not be infinite. Your most provocative comment is that "we know there is more beyond the Big Bang horizon." Would be great to explain either in comments or on the next video how it is that we know that. Is it a mass balance calculation? Or some other way? Again, great series and a great video in particular! Should be mandatory in all primary and secondary schools globally! Keep up the great work. We need so much more of this sort of content...
John It actually could be, we just have no way of knowing because we can only see the observable universe, the area of the universe where light has had the time to reach us.
It's true, the first generation of stars didn't form from the stuff of earlier stars, they formed from the remnants of the big bang. They were large and short lived and when they exploded formed huge black holes. The elements heavier than hydrogen, helium and lithium were created in these giant explosions, so anything like the Earth has to be in at least a second generation star system. In fact our sun is a 3rd generation star: made from an exploded star, made from an exploded star, made from the remnants of the big bang.
Eóin Ó hIcí, he classified it as yellow dwarf later on, which is a (slightly ill-chosen, but apparently rather common) name for G-type main sequence stars. Useful for distinguishing them clearly from giants, and certainly not wrong.
I'm not him to answer this, but he don't know for sure. Actually, no one really knows, scientists make this assumption because our observable universe has been increasing throughout time and will still continue increasing for a very long time, as light from more and more distant objects reaches the required time to reach us, and because astrophisically speaking, it will be too weird to matter and stars just dissapear from that "barrier" (also, it's not a barrier, it's just a term to identify where our planet's scientists cannot see )
Well that was Feynman at work . Appreciate it. Also make these kind of videos for individual items in the work , say one like this on black holes and so forth coz you make it understand nicely.
This is incredible! I have some things you have missed out: I think you should of added a category for novas. There a supernovas (you have covered them), hypernovas (superluminous supernova), kilonova (When a neutron star explodes). But other than that im pretty sure you covered it all!
Just stop. you might be right for a few of them but stop generalizing a whole group of people. An atheist can disagree with astronomy just as easy as a Christian. The last thing you should do as an open minded individual is flex arrogance. It deters some people from eventually being on your side. Besides, making fun of Christians is old news.
This is my favorite map so far. Great job on these I love every one and wish I could get your voice on every map at home. Just look at it and push play and get this same introduction video through out the map. Make it a digital map and use the same concept of this video. That would be awesome.
There is something breathtakingly profound that only in the last few years of our universe's billions-year history have these facts about the universe been so easily shareable with the only life forms that we know about.
I have 14 questions: 1-How unusual is our Solar System? Some observed planetary systems contain Super-Earths and Hot Jupiters that orbit very close to their stars (even closer than Mercury). Systems with Jupiter-like planets in Jupiter-like orbits appear to be rare. Is it because of our lack of data, given the difficulty of observing exoplanets? Or can it be explained by the grand tack hypothesis? 2-How does accretion form planetary systems? 3- Where did Earth's water come from? 4-Are there any planets beyond Neptune? 5-What is the explanation for the elongated orbits of a group of Kuiper belt objects? 6-How do other solar-like stars generate their magnetic fields, and what are the similarities and differences between stellar activity cycles and that of the Sun? 7-Why is the Sun's corona (atmosphere layer) so much hotter than the Sun's surface? 8-What causes these transient radio pulses from distant galaxies, lasting only a few milliseconds each? Why do some FRBs repeat at unpredictable intervals, but most do not? 9-Is there a universal age-metallicity relation (AMR) in the Galactic disk (both "thin" and "thick" parts of the disk)? 10-Is dark matter a particle? 11-Why is there far more matter than antimatter in the observable universe? 12-Some large features of the microwave sky at distances of over 13 billion light years appear to be aligned with both the motion and orientation of the solar system. Is this due to systematic errors in processing, contamination of results by local effects, or an unexplained violation of the Copernican principle? 13-Is the universe heading towards a Big Freeze, a Big Rip, a Big Crunch, or a Big Bounce, or is it part of an infinitely recurring cyclic model? 14-Is there other life in the Universe? Especially: Is there other intelligent life? If so, what is the explanation for the Fermi paradox?

1) You mentioned "meteroids", but there are also "meteors" and "meteorites". They are further subdivided in chemical composition "Iron meteorites", "Pallasites", "Mesosiderites", "Chondrites", "Chondrites" and "Stony meteorites". All of these are even further subdivided in specific families (we think they come from the same ejection events in the Solar System's history).
2) There are populations of asteroids in the inner Solar Sytem not directly associated with the Asteroid Belt: "Apohele", "Atens", "Apollo" and "Amor" are all kinds of "Near-Earth Asteroids". There are "Trojan Asteroids" for Venus, Earth, Mars, Jupiter, Neptune and Uranus and they are divided in kinds depending if they are in the leading or trailing motion of the planet (in Jupiter you have the "Greeks" and the "Trojan Trojans") and there is also the "Hilda" population which is also in resonance with Jupiter. Asteroids can also be subdivided in dynamical cathegories called families: "Eunomia", "Eos", "Flora", "Koronis", "Vesta", "Nysa", "Themis" and at least 100 more identified families.
3) The outer Solar System asteroids and minor bodies are not only in the Kuiper Belt. For example, there are "Centaurs" (before the Kuiper Belt), "Scattered Disk objects" (which are overlapping and farther than the Kuiper Belt) and "Detached Objects" (which constitute the extended scattered disk and might go as far to overlap with the inner Oort Cloud). Kuiper Belt objects are divided in kinds like "Plutinos", "Cubewanos" etc... depending on their dynamical history. Detached Objects include "Sednoids" for example. All Kupier Belt, Scattered Disk and Detached Objects are called "Trans-Neptunian Objects" and for Detached and Oort cloud objects they are called "Extreme Trans-Neptunian Objects".
4) There are other structures in the Solar System that you haven't mentioned: "Planetary Rings", "Propellers" (found in Saturn for example), "Arcs" (found in Neptune for example), "Gas torus" (like the one created by Io or the one by Enceladus), "Meteor Streams" and interplanetary dust can also create some structures like the "Kordylewski Clouds" (found in the Earth-Moon system).
5) Moons in the Solar System are highly cathegorized in families. For Jupiter: "Galilean Moons", "Amalthea Group", "Himalia Group", "Ananke Group", "Carme Group", "Pasiphae Group" and other statellites which are independent of any group. For Saturn: "Inuit Group", "Gallic Group", "Norse Group", "Alkyonides Group"... And dynamically moons are classified in "Inner Moons", "Large Satellites", "Irregular Satellites", "Prograde", "Retrograde", "Co-orbital Moons" and "Ring Shepherds".
6) Comets have also dynamical kinds: "The Sungrazers" which include "Kreutz Sungrazers", "Meyer Group", "Kratch Group" and "Marsden Group". There are "Long period comets", "Short period comets" and "Hyperbolic Comets". There are "Binary Comets" aswell as "Binary Asteroids" also.
7) You mentioned the Heliosphere. In fact it is made of the combination of different structures with wildly different physical regimes where different phenomena are occurring: "Heliopause", "Bow shock", "Hydrogen Wall", "Termination Shock", "Heliotail" and "Heliosheath".
This is a very cool list, thanks for this! And good point about the blue dwarf, I should probably have included that in as well. It is always tricky to draw the line because each extra thing I add increases the time of the video. Thanks for the feedback, much appreciated!
@@domainofscience No, thank you for taking your time and be sucha good sport. This is anawesome video really. Making schemes for these is a crazy goal to archive and you have done it. Congratulations
@@domainofscience I want the video to be longer tbh : )
by point 5 you were just pissing me off
Interesting and informative video. A must see for everyone.
Great video!! Carl Sagan would be proud! Keep up the good work, Sir!! 😁
I really really really like these videos of yours. Your efforts are appreciated. And the illustrations as well as the cohesive-ness are awesome. Thanks!
Clicked this video faster than the universe running away from us
Beautifully constructed. Love the short explanations of each and absolutely spot on choice of background music!
Every time I see a video like this I feel like switching my field and start learning astrophysics :/
This is the best space science video i have seen on you tube so far.
Nobody:
Scientist naming intense object: 𝘽𝙇𝘼𝙕𝘼𝙍
ok
Sounds like a Pokemon
This channel is a bliss! Should be shown in every school.
11:57 how do the things in the universe travel faster than the speed of light?
They aren't actually travelling through space faster than the speed light, but space itself keep expanding faster and faster, making the distance between us and them increase so that they get further away from us faster than the speed of light. Imagine two sharpie dots on the surface of a balloon that is being blown up, the dot's get father apart even though they are not moving. The ever expanding space between them is what we call dark energy.
@@domainofscience Thanks for responding, it's awesome to see interaction with viewers!
So dark energy isn't pushing things through space, it's actually spreading out space itself? Without *moving* the space(-time)? But light still travels through the warped space-time at unwarped speeds, rather than being accelerated along with the matter?
Shouldn't light be accelerated too as the expansion occurs?
Thanks for replying, hope I'm not grilling too much.
@@calebhale9865 Hey no probs! Yes everything you just said is correct, and light doesn't accelerate, it actually gets stretched out to longer wavelengths so becomes red shifted as it sort of expands along with the space expanding.
This video is truly amazing! Thank you for this brilliant overview, it helped me a lot.
I also like your illustrations, helps me to remember terms and concepts visually.
You forgot the biggest thing in the universe. Yo Mama.
Seriously though, really nice presentation. YT needs more content of this quality!
That bit about neutron stars and the atoms in their core was the best explanation I've ever seen.
You are Incredible, Genius!! You have uploaded awesome videos which made me so curious to understand topics of Astronomy, Math, Physics, Chemistry, Biology and other stuff
The best description of all the universe that we had known till now... Waiting to see many more stuffs getting added as man could find the ways to travel beyond our galaxy🚀✨
Thought it was a space map. Loved the video though.
The king is back
One of the best informational videos I've ever seen on TH-cam. Well done!
Can we have a map of Astronomy/Astrophysics as scientific disciplines?
Yess please we love your map videos would want to see more of them
Thank you very much. Can you please keep making more videos. I've watched every single one of them at least twice and this one four times already.
This was so good.
@Arthur78 nice profile pic
For mystries, I wanted to see if you would put strange matter but sadly no, yet this is one of the best videos on space that I found so far, great job, was really surprised you remembered dark energy. keep up the good work
Have you considered doing a map of the Earth Sciences? I’m a geologist and I hate how much of a bad rap geology and the other earth sciences get.
I’ve printed all your maps and pinned them to my room’s walls. It reminds me of all the things I need to do in life. Bravo!
❤❤❤
DOS please do a map of eletric enginnering.I never asked you anything 🙏
Daniel de Souza e Silva na that shit sucks I would know
just gather everything that is related to electricity from every map.
That was actually amazing! I actually retained 70% of that which is impressive. Quality video lad.
There are gravitationally bound structures larger than superclusters: galaxy filaments.
www.vice.com/en_us/article/zmj7pw/theres-growing-evidence-that-the-universe-is-connected-by-giant-structures
Are you referring to this?
@@Vagabond-Cosmique I think galaxy filaments (or walls) have been known for a long time, but now they are discovering they they contain most of the dark matter of the universe.
Terrific video. 2 thoughts in response: 1. Have you thought about including the strange attractor regions of the universe? I feel like you skip quickly over the known structure of the universe beyond galaxies and galaxy clusters, and how they are structured/moving as well. Highly filamentous, etc. 2. You mention twice that the universe may/may not be infinite. Your most provocative comment is that "we know there is more beyond the Big Bang horizon." Would be great to explain either in comments or on the next video how it is that we know that. Is it a mass balance calculation? Or some other way? Again, great series and a great video in particular! Should be mandatory in all primary and secondary schools globally! Keep up the great work. We need so much more of this sort of content...
You definitely made it seem so creepy and scary out there but your animated poster is accessible and so cute! Love it!
You answered my question at 12:30. I love your channel
The only thing that bothers me are the highlights on the black hole's event horizon.
Exactly the video I was looking for so far thank-you so much best ever found ❤
I'm not sure this guy understands "infinite".
. . . ..but can any of us, really?
collab orator well the universe could be infinite
Jeremiah Laing it decidedly isn’t
collab orator the universe is not infinite
John It actually could be, we just have no way of knowing because we can only see the observable universe, the area of the universe where light has had the time to reach us.
I have a bigger infinity than you
Loved this! Minor detail “Kuiper” belt, with a “u”, or so most sources I’ve seen say.
You ever feel like you’re small and insignificant? Nah me either
I loved this. One thing I noticed that you missed is iron stars, which is the next step after a black dwarf, but it is very niche, so no complaints.
I think you missed antimatter.
and that is important so i think you should make video about it.
by the way thanks for this amazing video .
We all kind of miss it 😉
That was a super simple way to explain something extremely complex , thanks for the video.
7:11, if stars are born because another star exploded into a nebula, then how was the first star formed?
It's true, the first generation of stars didn't form from the stuff of earlier stars, they formed from the remnants of the big bang. They were large and short lived and when they exploded formed huge black holes. The elements heavier than hydrogen, helium and lithium were created in these giant explosions, so anything like the Earth has to be in at least a second generation star system. In fact our sun is a 3rd generation star: made from an exploded star, made from an exploded star, made from the remnants of the big bang.
@@domainofscience this is all amazing honestly but where did the energy to cause the big bang come from?
@@theepickoala2293 no one knows.
@TheEpic Koala It came from God.
@@stza16 jesus christ just stop already
thank you so much for all these videos. im 45 and still learning! Dankeschön 🙏
HOLD ON
technically we can't reeeally actually say it's infinitely big
The math says that
Kazataca Yes, at the end he said we don’t know for sure if the universe if infinite or finite because we are limited to what we can observe.
Make a triangle
In the first 30 seconds he called the universe infinite and the sun a dwarf star, neither of which are true
Eóin Ó hIcí, he classified it as yellow dwarf later on, which is a (slightly ill-chosen, but apparently rather common) name for G-type main sequence stars. Useful for distinguishing them clearly from giants, and certainly not wrong.
Absolutely Amazing. Great work.
When you said that we know there is stuff beyond the observable ring, how do we know that?
I'm not him to answer this, but he don't know for sure. Actually, no one really knows, scientists make this assumption because our observable universe has been increasing throughout time and will still continue increasing for a very long time, as light from more and more distant objects reaches the required time to reach us, and because astrophisically speaking, it will be too weird to matter and stars just dissapear from that "barrier" (also, it's not a barrier, it's just a term to identify where our planet's scientists cannot see )
I love it when you make these kinds of videos.
.... you forgot cute puppies. the universe has cute puppies :)
Great stuff. I especially love ending on the mysteries and the unknown universe. Very exciting to know even more discoveries are coming.
"Infinite things in space"
Me: *are you sure about that?*
Well that was Feynman at work . Appreciate it.
Also make these kind of videos for individual items in the work , say one like this on black holes and so forth coz you make it understand nicely.
I think you forgot life.. Oh well, Probably not important
This is incredible! I have some things you have missed out: I think you should of added a category for novas. There a supernovas (you have covered them), hypernovas (superluminous supernova), kilonova (When a neutron star explodes). But other than that im pretty sure you covered it all!
Where is my girlfriend? Oh I see what you say now...
Fantastic work!! ... most useful especially for the youngs ... well done ... plz keep it up ... and thank you very very much indeed ...
You missed Wheatley
If anyone gets this 👏
space!........space!.....spaaaaaaaace
Your maps are wonderful. Every science class would benefit from one. I'll buy some soon!
All the dislikes are from theologist Christians
Just stop. you might be right for a few of them but stop generalizing a whole group of people. An atheist can disagree with astronomy just as easy as a Christian. The last thing you should do as an open minded individual is flex arrogance. It deters some people from eventually being on your side. Besides, making fun of Christians is old news.
wow! i got chills watching this. the universe is fascinating mashallah
Things that exist in space: Epstein not killing himself
Can’t thank you enough for all the maps you created! Tremendously useful!
mükemmel, hem matematik hem uzay videon. bu iki video için sana minnettarım.
I love these type of videos! Great job! The universe is truly amazing and beautiful
This is my favorite map so far. Great job on these I love every one and wish I could get your voice on every map at home. Just look at it and push play and get this same introduction video through out the map. Make it a digital map and use the same concept of this video. That would be awesome.
Such a beautiful explanation, definitely puts our life into perspective
There is something breathtakingly profound that only in the last few years of our universe's billions-year history have these facts about the universe been so easily shareable with the only life forms that we know about.
I have 14 questions:
1-How unusual is our Solar System? Some observed planetary systems contain Super-Earths and Hot Jupiters that orbit very close to their stars (even closer than Mercury). Systems with Jupiter-like planets in Jupiter-like orbits appear to be rare. Is it because of our lack of data, given the difficulty of observing exoplanets? Or can it be explained by the grand tack hypothesis?
2-How does accretion form planetary systems?
3- Where did Earth's water come from?
4-Are there any planets beyond Neptune?
5-What is the explanation for the elongated orbits of a group of Kuiper belt objects?
6-How do other solar-like stars generate their magnetic fields, and what are the similarities and differences between stellar activity cycles and that of the Sun?
7-Why is the Sun's corona (atmosphere layer) so much hotter than the Sun's surface?
8-What causes these transient radio pulses from distant galaxies, lasting only a few milliseconds each? Why do some FRBs repeat at unpredictable intervals, but most do not?
9-Is there a universal age-metallicity relation (AMR) in the Galactic disk (both "thin" and "thick" parts of the disk)?
10-Is dark matter a particle?
11-Why is there far more matter than antimatter in the observable universe?
12-Some large features of the microwave sky at distances of over 13 billion light years appear to be aligned with both the motion and orientation of the solar system. Is this due to systematic errors in processing, contamination of results by local effects, or an unexplained violation of the Copernican principle?
13-Is the universe heading towards a Big Freeze, a Big Rip, a Big Crunch, or a Big Bounce, or is it part of an infinitely recurring cyclic model?
14-Is there other life in the Universe? Especially: Is there other intelligent life? If so, what is the explanation for the Fermi paradox?
