Introduction (to anyone listening!)

Beitragvon m4r35n357 » Di 13. Apr 2021, 15:21

I am an amateur both at coding & physics, interested in visualizations in Special & General Relativity.

I have done some YouTube videos of the Twin Paradox from 1st person perspective using POVray raytracer.

Also a Javascript canvas black hole orbit explorer (equatorial).

Finally, c code for ODEs and Black Holes using various combinations of symplectic integration, Taylor series integration and automatic differentiation.

I registered here because there are few resources for coding visualizations of relativity. I like this site http://www.madore.org/~david/math/kerr.html, and Andrew Hamilton has some good videos but I can't understand his papers ;)

I came here because I saw some of your posts & videos, and realized that there is a free version of Mathematica in the Raspberry Pi OS! I might have questions at some point . . . .

Good job, although the videos lack a numeric display that tells the viewer what velocity the observer has relative to the background. I also don't get why the videos "earth gravity" and "moon gravity" show distortion, since their gravity is not strong enough to produce noticable gravitational lensing or such high freefall/escape-velocities that aberration would be visible to the naked eye, those videos need better explanation.

Madore's site is one of the best regarding the Kerr Metric.
