The universe isn't just a vast empty ocean sprinkled with galaxies – most of the atoms are actually drifting in between, in the intergalactic medium.
If we look closely, we can see who is in charge here: Quasars, the single most powerful objects in existence. As small as a grain of sand compared to the amazon river, they reside in the centers of some galaxies, shining with the power of a trillion stars, blasting out huge jets of matter, completely reshaping the cosmos around them. They are so powerful that they can kill a galaxy.
What are they, and how do they mold the structure of the universe at their whim?

Learning about space feels like the equivalent of gaining awareness of the world around you as a kid
-
It's absolutely nuts that most of the universes mass is located between galaxies, not inside them
-
1:21 nice little cheeky gomu gomu no mi reference.
-
Quasars, active galactic nuclei, and star-formation "quenching" are some of the most complex things in astrophysics, yet this video explains & animates them beautifully! Great work as always!
-
People aren't talking enough about the phenomenal background music. It really enhances the visuals and the information being told
-
Applause to the team who worked on this, animation was eye candy and the writers explained everything clearly and simply!
-
Every space-related Kurzgesagt video makes me realize that how valuable and beautiful our own planet is.
-
"If theres a hole theres a goal" . -guy who got sucked into a black hole
-
The concept of time dilation near black holes always blows my mind. It's mind-bending to think about how time can slow down near such immense gravitational fields. Black holes truly bend the rules of our familiar reality.
-
Shoutout to the motion graphics artists behind this
-
It so hard to comprehend stuff like that, honestly I spent a lot of time just wrapping my head around the fact that the time when something happens and when we see it due to the light needing to move through vasts amount of space to seem like a mere dot or line in the sky is amazing to me like what if a minute streak across the sky happened when my ancestors were alive? and it took THIS long to reach someone's eyes? just makes you appreciate everything a little bit more.

Space is terrifying. Beautiful, but terrifying. Ever since I first learned of quasars, I've wondered if some day Earth might get blasted by the polar jets from a quasar. We'd have no way to detect it, much less defend ourselves from it. Too often it feels like we are a sitting duck in a sea of violent chaos.
-
Really love the animation in this episode. Somehow even better than usual. Amazing job, folks!
-
That visuals at 5:50 where you can not only see the radio lobes, but they illustrate how it carves out a void in space is just amazing visual communication.
-
Ah yes existential crisis at 9 in the morning.
-
The amount of work this video must’ve taken is unbelievable. Stunning visuals and spot-on soundtrack!
-
Can we talk about how INSANELY beautiful Kurzgesagt's animations got lately? I mean, they were always beautiful, but FOR GOD'S SAKE, just look at this! They somehow manage to keep their charming characteristic style, while making their science videos a full art piece. I can't put my finger on what exactly makes their new animation so amazing, but it's just STUNNING and every time I finish watching one I can't wait to see the next one.
-
Alright which one of the cheeky animators snuck in a one piece reference? 1:22
-
Love the fact that one of the animators put the gomu gomu no mi fruit in the sky as a constellation.
