This tutorial shows how to use either Red Giant Trapcode Particular or CC Particle World to create a particle tunnel. Part of my Makin' #wormholes series, showing how to create really cool, sci-fy tunnels in Adobe After Effects.
Christopher Nolan's 2014 epic Interstellar attempted to scientifically accurately depict black holes and wormholes. Which won the team at DNEG an Academy Award. My tutorial produces a fairly decent recreation of the wormhole effect and should give you the basic look as I'm sure you could improve upon it.

cp=thisComp.activeCamera.toWorld([0,0,0]);
sp=thisLayer.toWorld(effect("CC Sphere")("Offset"));

y=cp[1]-sp[1]; alpha=Math.atan2(y,x);
