A black hole you can throw things into

  1. 1PA

    We have a black hole at home — with actual relativistic physics, live in your browser. I'm Sasha (Alexander) Plavin, an astrophysicist at Harvard's Black Hole Initiative studying quasars and black hole environments. I work with raytracing/radiative transfer simulations professionally, and wanted to make one anyone can play with — so I built this app. Put the black hole onto your screen (any browser), or directly into your room with AR or VR (requires WebXR, for example Chrome on Android, or any VR headset). When looking around, pay attention to unintuitive relativistic effects: rays…

    Just for fun and self education, I've built this over a weekend to teach myself why orbits exist, not just show planets going around. Something that was never clearly explain to me in school. It opens with a guided tour that builds the idea up step by step: two bodies and the equal/opposite force, inertia (the Sun is removed and Earth just drifts straight), then "an orbit is falling and continuously missing," cosmic velocities with a little rocket, Voyager 1 & 2's real gravity assists (the clock runs the actual 1977–1989 dates so the planets orbit into their grand-tour alignment and the…

    I built this over the weekend. Any feedback is appreciated. Please note you will need a WebGL enabled browser. Thank you for checking it out. --UPDATE-- HN Traffic is strangling earthbit. There is sporadic downtime due to the web services I am using, if no transactions appear after a few seconds, then please try again in an hour.

    Hi. I made a video crash course about Terraform 0.12. It's one of four I want to do. I would love to show you what I've made so far and get your feedback and thoughts. The course is financially free but does require an email to signup (a limitation of the platform I'm using): https://www.thecloud.coach/terraform-crash-course Let me know if you have any questions. Thanks.

    This was my recent weekend project, aimed at teaching me JavaScript, a bit of HTML5, and (mostly) WebGL. The orbital data are from NASA JPL. I was inspired in part by this Flash app: http://www.dynamicdiagrams.com/wp-content/uploads/2011/04/orrery_2011_bce.swf, but wanted to do something in 3D. Coming from the games-dev world, this is my first introduction to web coding. The UI is jquery. I mostly used http://learningwebgl.com/blog for the 3D stuff. Being WebGL, it will work mostly on Chrome, Firefox 4 Beta. Forget about IE. I needed to figure out how to render text to the WebGL canvas - I…
