Dope Tech Episode 2

<<@Liam-fx3ir says : Obviously Endor and Yavin IV are planets, clearly we need a new definition>> <<@vizonegames1368 says : Isn't that how most definitions are made? I'm not familiar of a definition being made in a manner other than to describe something.>> <<@ARockRaider says : i propose we call the earth a binary planet system! now the rest of the rules work and the moon just needs a better name. additionally i propose we call it Antimerica and rename the Earth to America! or possibly Macromerica?>> <<@MrARock001 says : The history of the categorization of "planets" should be studied as an example of the limits of categorization. I think we should go back to the original definition of planets: Those wandering lights in the sky that don't behave like the rest.>> <<@blaz2892 says : This has to be science nerd engagement bait>> <<@QM42069 says : By your own argument and the way you're interpreting the chart, should Ganymede, Callisto, Io and Titan not also be planets? They all have hydrostatic equilibrium, and if Jupiter and Saturn weren't there (stupid hypothetical we're using apparetly) they would all orbit the sun or fall into the same kind of relationship the Earth and Moon have by your argument. What about Europa? Another commentor said it, but is it a "half-planet"? Or is Europa technically a moon to the "planets" Ganymede, Callisto, and Io?>> <<@ariadnavezuvian8458 says : What's wrong with you, people? Two planets orbiting each other could exist. The Earth and the Moon cold be considered a pair of sister planets, double planetary system. Why do y'all behave like the author FORGOT THE EXISTING OF THE EARTH?!! The planet we live on? The planet mentioned in the same video? Didn't cross your mind that if mistake is so obvious it is not a mistake?.. "Clear the orbit" means "clear from debris" And even so is not actually correct because Jupiter has asteroids sitting on his orbit. The only difference is it is Jupiter who controls it's motion.>> <<@DasSeltsameExemplar says : Planets should be defined by their own self-influence An asteroid and dwarf planet have no influence over their surface, thus rendering them completely exposed to outside influence from birth (My definition of self-influence is capacity for affecting the surface itself with geological activity, magnetospere as well as be able to well differentiate volatiles into their respective surfaces and keep them protected, a planet can do all of theese quite well over long periods of time ranging from icy to metallic crusts) Objects ranging from the mass of pluto to the moon cannot be planets because of their inability to keep a significant influence over the surface, with our luna basically behaving like an asteroid despite being far from one, historically luna at best had a modest magnetic field with partial resurfacing on the side facing earth and while keeping a volcanic atmosphere for a while (in it's prime meerely thicker than mars's), meanwhile pluto can keep an atmosphere and cryovolcanic activity purely because of it being icy, thus more malleable. The only object that could be considered a planet that is less massive than mercury would be the ganymede, ganymede because of it's highest mass along with having super differentiated interior, possesing a magnetic field along with a significantly altered surface from a mixture of self inflicted and tidally-caused crustal deformations making it's surface to how it is, now i'm not sure if the heat from the interior would ever pierce throught ganymede's thick icy crust to produce cryovolcanism in the present day, but it could do that as well. Now i would exclude all other massive moons from being considered a planet either due to them borrowing self-influence through tidal forces from their parent planets (f.e: Io, Europa, Triton), from specific compositional or evolutionary reasons (f.e: Callisto, Titan), or because they were proven to be far too weak to be a planet (Luna)>> <<@Midknight129 says : The only "planets" I recognize are Mercury, Venus, Mars, Jupiter, Saturn, The Sun, and The Moon. Earth is *not* a planet, it's Earth. Neptune, Uranus, and Pluto are *not* planets, they're just other gods in the Roman pantheon. And there are *certainly* not planets around any of the Fixed Stars in the sky, since they are *clearly* too small. ... ... ... ... ... For legal reasons, this is sarcasm.>> <<@paschalconneely2374 says : Others have remarked that the sheer size of the moon relative to the earth (when compared with other moons and their host planets), the system could be described as a binary planet. At any rate, luna is an extraordinary moon and has had a serious role in the billions of years the two have orbited the sun.>> <<@VeryShrimple says : The moon doesn't have enough gravitational pull on earth to be qualified as a binary planet right? So it's still a moon>> <<@gummibear555 says : Bro is on no team🥀>> <<@EngAnon says : Oh, come off it. We all know that the seven planets are the Sun, the Moon, Mercury, Venus, Mars, Jupiter, and Saturn. We even named the days of the week after them, for Kepler's sake!>> <<@ententes says : This is the biggest cope video of all time>> <<@thisis103 says : Thank you for this. The mere existence of Luna (and Mars) still baffle me to this day, and I believe that Luna would be better categorized as a planet in a binary system. I think theories such as the LMO further support this.>> <<@PeterFamilyGuy99 says : "The moon is a planet" bro no the fuck its not 😭✌>> <<@EliTheMac says : i KNEW PLUTO WAS A PLANET ITS MY FAVORITE THE IAU CAN… THEY CAN…. THEY CAN GO TO H*CK! (i’m sorry god)>> <<@VoidGMZ says : Dont let jerry smith see this>> <<@kellymoore5517 says : everything is a human construct. its whatever we say it is>> <<@gordonisnowhere says : a lot of iau apologists in here>> <<@ColaCat22 says : You misinterpreted the first one, it needs to be in orbit around the sun, and nothing else. Technically speaking, everything in our solar system is orbiting a black hole, but we wouldn’t say that. We’d say the sun is.>> <<@malakaiarnold6311 says : The "It must orbit the sun" rule: Am i a joke to you?>> <<@mywillowself says : Except an orbit is an ellipse, and not a smoothed polygon shape, so the moon does not in-fact orbit the sun.>> <<@haris6772 says : As an addition to all the other comments disagreeing with the video, id also like to point out that Pluto's orbit is vastly different to that of the other planets. While the other 8 have nearly circular orbits in the same plane, pluto has an elliptical orbit at an angle to the plane, meaning for a small part of it's orbit it's closer to the sun than Neptune.>> <<@user-theRealtimehack says : Not C bc of the Earth>> <<@misterglo1394 says : just because it’s big enough to clear its orbit doesn’t mean it does, as is evident here. the major moons of jupiter were above the line too after all>> <<@Mary_Jane_theMommas says : pluto is a plant, the moon is also, and so is ceres, and the sun, and everything, and you go somewhere empty enough.>> <<@euanstokes2828 says : This video really misses the point of the IAU definition. The reason an additional criteria was added to disqualify Pluto as a planet is because we kept finding other dwarf planets in the Kuiper Belt. There are dozens of them now. The recategorisation happened because we discovered Eris, which was bigger than pluto. Either we must accept all Dwarf Planets as Planets, raiding the number dramatically, or none of them can be accepted. The latter option was chosen to avoid desecrating the category of planet, that is to say that these objects, Dwarf Planets, all have far more in common with each other than with the other planets. Thus the 'clear their orbit' criterion was introduced to restrict the category of planet to the few objects that define the suns orbit. Now, a planet must by definition be a large object not simply an asteroid that rounds itself. And by the way, no moon can ever meet criteria 3 never mind criteria X. Yes, the moon would be big enough to clear its orbit if the Earth didn't exist, but the Earth does exist. If my Grandmother had wheels she would have been a bike.>> <<@igorkhac4105 says : Stop calling our moon the moon!!!! Its name is Luna! Moon of Earth is Luna! Not "the moon" its Luna!!!>> <<@Mimaspacegaming52 says : son 🥀🥀💔>> <<@Nysvarth says : Based on criteria A there are no planets in the universe outside of our solar system.. since it specifically says it must be in orbit around "the sun".>> <<@alextgordon says : Imagine that the Earth and the Moon were the same size. Which one is the satellite? Presumably such a system exists somewhere out there in the universe.>> <<@miguelsilva9118 says : I think this was a bit of a fail of a video. Very rare L for MP.>> <<@That_TS_STEM_Nerd_13 says : The Earth and Luna could be argued to be a dwarf system like Pluto and Ceres.>> <<@seanmcalevey4566 says : Tendentious argumentation. Hard disagree>> <<@hugorodriguez8672 says : Rare minutephysics L>> <<@modi4evr says : exoplanet proxima b will hate this>> <<@fafnirbane says : You define the moon's orbit inconsistently across points 2 and 3>> <<@toi_techno says : The planets are satellites of the Sun So there are no planets unfortunately>> <<@Roovinggoove says : 0:33 this seems really biased, you gave the most accepted method that shows if something is orbiting the other. So saying "you could consider it to be orbiting the sun" is kind of ridiculous>> <<@ernanipozza says : This is either ragebait or a very stupid video.>> <<@PlainBlueFolders says : Broke: Moon isn’t a planet because it can’t clear its orbit Woke: Earth isn’t a planet because it can’t clear its orbit>> <<@andrewg.3281 says : I disagree with the notion that arbitrary definitions are "un-scientific". For example, the start of space is the Karman line, which is 100km above sea level. There's no difference between the area just above and just below the line. It's just set there so we have an agreed upon distance when we talk about space. In the same way, the line for what makes a planet can be arbitrarily set to whatever we want, without it being "un-scientific". Especially since there's so many different attributes that makes drawing the line inherently arbitrary. Does an atmosphere matter? How about magnetic fields? Does orbital path matter? There needs to be a line drawn someone arbitrary so that we know what we are talking about when we say certain words. Saying "These 8 feel more special, why is that?", and making a definition to describe it is a very scientific process. Even the example of the definition of a dinosaur demonstrates this. Why are dinosaurs and mammals different? They had a common ancestor and have several similar features like skeletons, eyes, brains, etc. The definitions we have are because we thought the aminals we call dinosaurs and the animals we call mammals are different. So we made definitions based on those predetermined groups.>> <<@kingguydan says : I just keep finding more and more opinions from educational YouTubers that go against more and more of CGPGrey's opinions and this seems quite odd. I highly expected for their intellectual relationship to be more symbiotic than this>> <<@crawhey says : It was a planetoid before it fell on Earth.>> <<@LiveFreeOrDieDH says : Pluto stans giving out lots of likes 😂 It's ok. Kuiper belt objects have value too.>> <<@alex10763_ says : This video is a joke>> <<@Biga101011 says : This is exactly my thoughts on it. They were discovering a bunch of stuff in the Kuiper Belt they didn't want to include and decided to make up a new reason to exclude them... and apparently Pluto along with it. I really like the arguments Stern made and the terms Unterplanets and Uberplanets to help distinguish. He also has a term lamda used to classify the difference between the two. The rollout and lack of clear definition of this system was disgraceful and it is a shame more in the scientific community are not calling them out for it.>> <<@speedster8861 says : Luna btw>> <<@recoveringMENSAn says : The silliness of 'had cleared it's orbit, is that the exact same object before the last asteroid crashes into it becomes a different class of object after the last 'neigborhood' asteroid has crashed into yet.>>
