It is part of my interest to understand the quantum world in a less abstract and weired way than it is currently situated in. I believe there is a more “newtonian” concept hidden in the weiredness of quantum mechanics, so I came up with this frictionless fluid model to describe the aether (the void of empty space). In this model structures (sort of vortices) can form appearing to us as “elementary particles” with their respective properties (like charge etc).

This simulation shows the evolution of an initial disturbance (in momentum) in an experimental aether. It is mostly axially symmetric because the initial conditions are, so it is easier to follow what is happening. Actually the initial disturbance is slightly off-center (0.1% of the simulation cube length) which becomes apparent towards the end of this video – I did this to show the extreme sensitivity to initial conditions.

Here you can see it in action.

After thinking about how our universe might work at the lowest level I got the idea that what we call “particles” are nothing but vortices in a frictionless fluid, so I made a simulation to test this idea.

So this is a simulation of an aether (1920×1080 grid; toroidal topology/wrapping) with an initial disturbance leading to the temporary creation of particles/anti-particles (aka vorticies), their annihilation and energy radiation. This pictures an intuitive solution to the wave/particle-duality, conversion between these 2 forms, why particles cannot be pinned down to an exact position (uncertainty), bremsstrahlung and a mechanism for “borrowing energy from empty space for brief periods of time”. Particles are accelerated/decelerated by waves of energy while repelling other particles and attracting their anti-particles.

The waves would actually travel at the speed of light, so this simulation is a super-slowmotion of what might actually happen at the smallest scale of our universe.

Colors and arrows indicate “direction of flow of free space”, brightness indicates pressure and white regions indicate vortex/particle centers.

This is my first draft of a particle based fluid simulation implemented using CUDA.

It displays 2 non-mixing liquids with different densities, lets say oil (yellow) and water (blue). From time to time I apply some push-force somewhere in the scene to cause some action. You can see pressure waves running through the fluid, waves and breakers appearing at the surface as well as drops and filaments forming and other surface tension effects.

The simulation consists of 65536 particles and each of it interacts only with its local neighborhood. By exchanging appropriate forces all of them together will form the fluid. All the phenomena written above are not programmed explicitly, but emerge from local particle/particle interactions. The simulation runs at 60 fps on a GeForce285GTX.

The video plays back at half tempo because it is set up to 30fps where the original rendering was 60fps.

My plan is to add (particle based) rigid bodies as well and to perform finite element analysis on them so they can break apart if external forces exceed the bonding forces.
