Well that's fascinating. Apparently stalker's anomaly distortion effects (for the gravitational anomalies) is actually fairly realistic - high amounts of gravitational force effectively create a 'lense' effect. I'm sure intense gravitational fluctuations (eg, the Springboard anomaly) does a much similar thing..
I think this confirms that if the Zone ever becomes a reality, I'm becoming a scientist. Studying the Zone is fascinating as fuck.
