If you don't mind me saying - poor naming and post title. This is much more interesting than the keyword phrases "particle simulator" and "physics" would suggest! Can you not cram something ALife related in there?

I don't know, I find the name pretty accurate – it is a particle simulator, after all.

It's a matter of specificity. Yes, it's a particle simulator, but given the Conway's Life feel to some of the examples, it at least seems like a high-speed, high-resolution cellular automata.

This is pretty fun, I like it, will take a look at the code later today. > Finally, I am legally obliged to inform you of the one law of exophysics: > YOU ARE REQUIRED TO TERMINATE A SIMULATION IMMEDIATELY UPON FINDING > EVIDENCE OF THE EMERGENCE OF SENTIENT CREATURES CAPABLE OF SUFFERING. LOL, I had to google "law of exophysics" to see if it is real.

I mean.. arguably... if the sentient creatures have emerged then is it ethical to kill them?

Well, factor in a slow extinction event and let it run for a few billion ticks. That way they have ample warning, and they might have even offed themselves within that timeframe.

Hey people, I built this particle simulator in ~500 lines of self-contained HTML/JS/WebGL2. It's designed to encourage creativity and exploration. You can just download one of those universes and open up the HTML file in a text editor to tweak the physical laws and constants. Then open it up in your browser to see the result immediately. I had a lot of fun exploring the beautiful emergent behaviors that arise from th…

Nice, this is really fun to play with!

I messed around with something similar a few years ago, based on (the code in) this video https://www.youtube.com/watch?v=Z_zmZ23grXE

Edit: Apparently there are a lot of these! This variant is also pretty cool (smaller particles, more like "fields"): https://www.youtube.com/watch?v=nu5aDIEoBk0

I love the emphasis on user exploration. And your way of writing the documentation is very welcoming. Awesome tool.

Thank you :)!

Sweet, thank you for the links! I'll surely learn something from what they've been doing :)

True, but that law was established to discourage any research in that domain, reducing the overall occurences of sentience-incidents and the resulting messy philosophical questions.

Thank you :) I can't edit it anymore, but will think of that next time.
