The Most Complex Origami Ever
Geometry is key. 
Not an video, just a drawing:
In 2022, Wageningen University, in the Netherlands, digitized and put online 1,180 drawings from 40 years of research on the root system of plants and therefore that of trees, these large plants whose woody stem branches from a certain height above the ground

Imagine if he knew about sound wave focusing!

I'm not sure why, but NASA says:
It's Black Hole Week! Grab your telescopes and get ready for a week of black hole exploration.
Black Hole Week - NASA Science
Goddard scientists created the visualizations on the Discover supercomputer at the NASA Center for Climate Simulation.
The destination is a supermassive black hole with 4.3 million times the mass of our Sun, equivalent to the monster located at the center of our Milky Way galaxy. To simplify the complex calculations, the black hole is not rotating.
A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds the black hole and serves as a visual reference during the fall. So do glowing structures called photon rings, which form closer to the black hole from light that has orbited it one or more times. A backdrop of the starry sky as seen from Earth completes the scene.
The project generated about 10 terabytes of data — equivalent to roughly half of the estimated text content in the Library of Congress — and took about 5 days running on just 0.3% of Discover’s 129,000 processors. The same feat would take more than a decade on a typical laptop.
This video reminded me of a transcript in which Ark was working on a theory:

Black Hole Week - NASA Science
Hang out at the event horizon with us this week
Come and learn about these strange balls of gravity here and on social media. Check out the links below to find our latest content and follow the #BlackHoleWeek hashtag on social media for even more content. No matter where you go this week, we hope that you’ll find yourself teetering on the edge of the event horizon — just don’t fall in!Monday, May 6
Welcome to the event horizon! Let’s get close to one and see what it would look like.Tuesday, May 7
All black holes have an event horizon, and the object’s mass defines the size of the horizon. Learn about black holes of all sizes, big and small.Wednesday, May 8
Even though light can’t escape once it’s inside the event horizon, we can still detect black holes by monitoring their effects on their surroundings. Follow along to find out more.
NASA Simulation’s Plunge Into a Black Hole: Explained
This new, immersive visualization produced on a NASA supercomputer represents a scenario where a camera — a stand-in for a daring astronaut — enters the event horizon, sealing its fate.Goddard scientists created the visualizations on the Discover supercomputer at the NASA Center for Climate Simulation.
