Video: Celestial bodies falling into a pool of water

What would happen if a scaled-down version of the Earth, the Sun or a black hole fell into a pool of water? It's a fun little experiment and also a showcase of some improvements of the renderer in version 0.8 - the raymarcher can now render mirror reflections and refractions in a (semi)realistic way.

These simulations have 2M particles, mostly used for the water. The block of water does not fit into the boundary exactly, hence the initial splash. I'm hoping to improve this in the future.
