I feel like all that time I’ve been practicing shading is starting to pay off.
Sitting atop a fractal surface of black holes, Tribert tries to make Adenine, one of the molecules in DNA, but he didn’t get it quite right, probably because he got distracted by the cats. Maybe next time, Tribert.

It’s been a challenging month, and I haven’t had a lot of success with my gouache painting lately. So I decided to go back to my old style of doodling cats and aliens on black holes with ink and colored pencils, where life makes sense and I know what I’m doing.

Epic NASA video takes you to the heart of a black hole — and destroys you in seconds By Stephanie Pappas
published 5/7/24
"...Researchers created the new simulation using the Discover supercomputer at the NASA Center for Climate Simulation. It shows a viewer plunging through the accretion disk of glowing gas around a supermassive black hole like the one at the center of the Milky Way. The viewer cartwheels through the plunge, passing ghostly racetracks of light particles that have orbited the black hole multiple times, finally hitting the point of no return: the event horizon, where nothing, not even light, can escape..."
Massive black holes drag and warp the spacetime around them in extreme ways. Observing these effects firsthand is practically impossible, so physicists look for laboratory-sized analogs that behave similarly. Fluids offer one such avenue, since fluid dynamics mimics gravity if the fluid viscosity is low enough. To chase that near-zero viscosity, experimentalists turned to superfluid helium, a version of liquid helium near absolute zero that flows with virtually no viscosity. At these temperatures, vorticity in the helium shows up as quantized vortices. Normally, these tiny individual vortices repel one another, but a spinning propeller — much like the blades of a blender — draws tens of thousands of these vortices together into a giant quantum vortex.
With that much concentrated vorticity, the team saw interactions between waves and the vortex surface that directly mirrored those seen in black holes. In particular, they detail bound states and black-hole-like ringdown phenomena. Now that the apparatus is up and running, they hope to delve deeper into the mechanics of their faux-black holes.

"Now, thanks to a new, immersive visualization produced on a NASA supercomputer, viewers can plunge into the event horizon, a black hole’s point of no return."
The animation, which simulates the view of someone falling into a black hole, demonstrates how the bizarre objects warp light and space as you approach them.
Ever wonder what happens when you fall into a #blackhole? Now, thanks to a new, immersive visualization produced on a #NASA#supercomputer, viewers can plunge into the #eventhorizon, a black hole's point of no return.
I realized that I haven’t showed you all of my black hole doodles yet! This is probably the most recent one. I can tell because the shading makes the holes look more convincing, and that took me a lot of practice to figure out how to do that. Can you find the waterbear?

To celebrate #BlackHoleWeek here is a collection of images, videos, interactives, activities, and background resources about black holes from NASA's Universe of Learning.
Happy #BlackHoleWeek to those who celebrate! Here's a pic I took a few years ago back when I worked at ESO's Paranal Observatory in #Chile. One of our 8.2 m telescopes was pointing at the centre of the #MilkyWay, home to Sagittarius A*, a #BlackHole 4 million times more massive than the #Sun.
Astronomers devoted almost a century to unmask this beast:
I've just discovered (should be Sir) Roy Kerr (https://en.wikipedia.org/wiki/Roy_Kerr) , #NewZealand mathematician famous for his solution for rotating black holes published a paper last month which showed #singularities do not have to exist in a #BlackHole, at least not how the 2020 Nobel prize winner Sir Roger Penrose described. For #Physics this is a huge deal. For #NewZealand media it wasn't worth a mention. But, here is a description of what he's done if you are game. https://flip.it/iwDh4a
