I assume everyone has seen the supposedly portal "paradox" where a blue portal comes smashing down on a cube and people argue if it shoots out the orange portal or not.Well, I built a simulation with a set of scenarios to look at, each introducing a new concept, slowly building up to the conclusion. In the end, everyone should hopefully be convinced that only one solution makes sense.I am more than happy to collect feedback and suggestions. Are the explanations clear? Is the pace good or should I spend more time on a specific concept? Do you have other scenarios in mind that are worth showing? Comments URL: https://news.ycombinator.com/item?id=50350400 Points: 1
