How The Immune System ACTUALLY Works – IMMUNE Kwabena Ofori Osei 31 Views • 4 years ago

To preorder IMMUNE click here: https://kgs.link/ImmuneBook –– It’s available in English and German and at online retailers it should be available in pretty much all countries too.Sources & further reading:https://sites.google.com/view/....sources-immunesystem human immune system is the most complex biological system we know, after the human brain, and yet, most of us never learn how it works. Or what it is. Your immune System consists of hundreds of tiny and two large organs, it has its own transport network spread throughout your body. Every day it makes hundreds of billions of fresh cells. It is not some sort of abstract entity. Your immune system is YOU. Your biology protecting you from the billions of microorganisms that want to consume you and from your own perverted cells that turn into cancer. It's so manifold that it is impossible to cover in one video, so we’ll make a series looking at different aspects of it. Today, what happens when your body is invaded and your first lines of defenses are engaged in a fight for life and death?OUR CHANNELS▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀German Channel: https://kgs.link/youtubeDE Spanish Channel: https://kgs.link/youtubeES HOW CAN YOU SUPPORT US?▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀This is how we make our living and it would be a pleasure if you support us!Get Merch designed with ❤ https://kgs.link/shop Join the Patreon Bird Army 🐧 https://kgs.link/patreon DISCUSSIONS & SOCIAL MEDIA▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀Reddit: https://kgs.link/redditInstagram: https://kgs.link/instagramTwitter: https://kgs.link/twitterFacebook: https://kgs.link/facebookDiscord: https://kgs.link/discordNewsletter: https://kgs.link/newsletterOUR VOICE▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀The Kurzgesagt voice is from Steve Taylor: https://kgs.link/youtube-voiceOUR MUSIC ♬♪▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀700+ minutes of Kurzgesagt Soundtracks by Epic Mountain:Spotify: https://kgs.link/music-spotifySoundcloud: https://kgs.link/music-soundcloudBandcamp: https://kgs.link/music-bandcampYoutube: https://kgs.link/music-youtubeFacebook: https://kgs.link/music-facebookThe Soundtrack of this video:EmergenceSoundcloud: https://bit.ly/3jEvquOBandcamp: https://bit.ly/2X30D2XLifeSoundcloud: https://bit.ly/3CBAybKBandcamp: https://bit.ly/37xr4juIf you want to help us caption this video, please send subtitles to subtitle@kurzgesagt.orgYou can find info on what subtitle files work on YouTube here:https://support.google.com/youtube/answer/2734698?hl=en-GB&ref_topic=7296214Thank you!🐦🐧🐤 PATREON BIRD ARMY 🐤🐧🐦▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀Many Thanks to our wonderful Patreons (from http://kgs.link/patreon) who support us every month and made this video possible:BBumbrazz, Sir Harry Farr, Abigail von Kelsch, Szabolcs Dombi, Conner Wilson, Enoch, Moody Bastard, Diego Marcheselli, Paxton LaRiviere, Richard Hagen, Robin Harn, Izzy Crow, Kristy Evangelista, Michael Baker, Tuna The Fish, @charlievankamp, Calvin Black, Justin Fisher, Jan Hübler, Anshul Choudhry, garshtoshteles, Mark Moses, Mau Magaña, seasar2000, Toda, newline, Matt, schubadu, Slumperd, Cracker, Josh Carpenter, Benedikt S., Jeti, Kevin Williams, Enrique Mejia, Juan Carlos Coto Sanchez, Paulmega, Jasmeet Singh, Austin Daily, Andrew Bourgeois, Andrew Dawson, Fin Brewin, Graesha Lizardo, Hagen, Diogo Moreno, Madeline McKinnon, akshay niranjan, The Entity, sontino catalano, Aubrey Temple, Terone, Oleksandr Bolgarov, Jacob Bell, Kyle Harmse, Henry Angulo, Luka Dulčić, mors741, Billyboots75, Joe Bedell, Merasmus 2.0, jimmy davies, PBYuki-Onna, Billy Z Duke

Look around you. Where are you? Where is this place you are occupying? Somewhere in a room, maybe in a city on a continent on a planet orbiting a star in a galaxy among billions. But… where is all of that? While this may feel like a daft question, it turns out that the concept of an absolute position is something humans made up.

In a nutshell, the universe is a big bag of space that has things in it. If someone removed all these things, the stars and planets and black holes and dust, there would just be empty space left. In empty space, the concept of having a position loses all meaning. Empty space is uniform, the same everywhere.

The new BLACK HOLE image explained by an ASTROPHYSICIST | Your questions answered
The new BLACK HOLE image explained by an ASTROPHYSICIST | Your questions answered Kwabena Ofori Osei 35 Views • 4 years ago

The Event Horizon Telescope collaboration just released the first ever image of the Milky Way’s supermassive black hole (the same group that took the first ever image of a black hole in 2019 - the one in the centre of the Messier 87 galaxy). What do we learn from this image? Why is it orange? Why is it different to the M87 image? Why is it blurry? And can we observe the same thing with the James Webb Space Telescope?

Why yes this was filmed and edited in a single day. Thanks for noticing. Yes I am exhausted.

👩🏽‍💻 I'm Dr Becky Smethurst, an astrophysicist at University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on *how* we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.
