Every Thing in Space

[@TheNerdySkier]

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

[@ttrash6404]

Thank you for 11:57! that one didnt make sense to me

[@Zurenza]

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).

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!

This is the best space science video i have seen on you tube so far.

[@mikip3242]

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".

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?

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?

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.

Shouldn't light be accelerated too as the expansion occurs? Thanks for replying, hope I'm not grilling too much.

7:11, if stars are born because another star exploded into a nebula, then how was the first star formed?

[@domainofscience]

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.

I'm not him to answer this, but he don't know for sure.

"Infinite things in space" Me: *are you sure about that?*

[@tichu7]

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.

Where is my girlfriend? Oh I see what you say now...

There is recent evidence that some hypergiant stars just collapse into a black hole without a supernova. A couple of stars just dissapeared and this is a possible explanation. Very wonderful video.

All the dislikes are from theologist Christians

[@WinmanVideo]

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.

Such a beautiful explanation, definitely puts our life into perspective

Things that exist in space: Epstein not killing himself

[@abhishekkochar9214]

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.

[@PolarFist]

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!

[@heff0d468]

I'll be impressed once you make a life-sized version.

[@cerka27]
