🌌 6-min random three-body chaos compilation 7 simulations, all unique, none predictable

💥 3 collisions · 4 escapes ⏱ Longest run: 929 years simulated 🌀 Most chaotic: 40.3% chaos score, 7917 close approaches 📊 Avg simulated time: 247 years per simulation 🎲 Hardest to find: 97 attempts to survive 89 yrs minimum ⚡ Fastest escape: 39.0 km/s (rel. pair: 45.9 km/s) 💥 Hardest impact: 824.0 km/s

In chaos, civilizations fall and rise.

Paper 5 — Boundary Dynamics: Resolution, Selection, and the Realization of Admissible States. If boundaries define what’s allowed, what determines what actually occurs? Answer: systems don’t choose — they settle into states that remain admissible under real conditions. S(n+1) = Resolve[S(n) | L, B(n)] Resolution = realization of admissibility (no optimisation, no teleology — just persistence) https://substack.com/@hybridmind42/note/p-195972037?r=75c2ac #BoundaryDynamics #ComplexSystems #Physics #ScientificClarity #BFPF

Over the past series of posts, I’ve been exploring how systems fail—and how some persist. Across engineering, biology, and digital systems, the same structural patterns keep appearing. This post brings them together. It’s a simple index of ten case studies, each showing a different way a system can fail, adapt, or disappear. No new theory here—just the map. “The Boundary Failure Series — A Master Index of Systemic Persistence” https://substack.com/@hybridmind42/note/c-249620403?r=75c2ac #SystemsThinking #ComplexSystems #BoundaryDynamics #BFPF #HybridMind42 #FailureAnalysis #Resilience #Engineering #Biology #Physics #StructuralAnalysis #Adaptation

I went out into the garden at 10:30pm in the dark to observe the meteorites. I gave myself time for my eyes to adjust. I wrapped up warm. Since I saw exactly zero bright flashes streaking through the heavens here's a picture if a cake i made recently #physics #astronomy #crushing #disappoint #cake #meteorites

This Earth Day, some dream of saving the Earth, while others dream of leaving it. Here's why using antimatter as fuel is our best bet for interstellar travel https://bigthink.com/starts-with-a-bang/antimatter-energy-interstellar-travel/?utm_source=fark&utm_medium=website&utm_content=link&utm_campaign=fark&ICID=ref_fark #stem #science #physics #astronomy #cool

I enjoy #physics and i enjoy #teaching so... when the adversarial school system got too much for me, the 'cruel mistress' known as #Youtube seemed like a potential outlet. When I get comments like this the blood and sweat is worth it. If you're interested check out , @physics-for-all-with-edward on youtube

The idea of a "color charge" confuses a lot of people, and the analogy certainly has its flaws. Here's how to understand the strong force without colors, and without group theory, too https://bigthink.com/starts-with-a-bang/the-strong-nuclear-force-made-easy-without-colors-or-group-theory/?utm_source=fark&utm_medium=website&utm_content=link&utm_campaign=fark&ICID=ref_fark #stem #science #physics #cosmology #interesting

Why do so few scientists use Fahrenheit? According to Isaac Asimov, the original 100°F "fixed point" may have been based on a sick cow with a fever. A 300-year-old error that still dictates US weather today. Precision matters. #HistoryOfScience #Physics #Brevity #Celsius

@thanetric@mastodonapp.uk But so to would Artemis 2. In the reference frame of the Solar system's barycentre, Ted and #Artemis2, whilst not co-moving, have similar paths now that they are both on Terra. We'd need to pick a reference frame closer to home, where Artemis 2 is now stationary and Ted continues to move. WGS-84 is the obvious choice, I think. I suspect Ted is already being measured in it. I *definitely* wouldn't pick one with a billionaire as the origin point. The billionaire hopping onto a private (or even public) jet would make it seem like Artemis 2 was moving once again. Aside from complicating what is already a non-inertial frame, this seems like cheating to keep raising Artemis 2's total. (-: Artemis 2 does get legitimate credit for a few thousand extra km, though, because the service module took its own path around the globe after separation from the crew module. @GetCarter@mastodonapp.uk #astronomy #physics #GNSS #GPS

Maybe this is too deep. But, give it a read and see what you think. I think I agree. "There’s something quietly unsettling about placing a photograph of a human neuron next to a simulated image of the large-scale cosmic web. The two look almost identical: delicate, branching filaments connecting dense clusters, with vast open spaces in between." #Science #Physics #Cosmology #Existence #Intelligence #News #Destiny https://discoverwildscience.com/our-universe-might-be-a-giant-brain-according-to-new-theories-1-397374
