I think we can all agree that the backwards world in RD is littered with inconsistencies and illogicalities, and while what I'm about to say has to be treated on a completely theoretical basis, I thought it may be interesting. I may be wrong. What would a 'real' backwards world be like? Well, while sitting thinking about this (I was bored) I came to a couple of conclusions, namely that it would be impossible to be either born into a backwards world, or enter one (as the RD crew do). The reason for the former of those is obvious, and of course it would be impossible to enter the backwards 'atmosphere', because the second you enter it, you would be thrown back out. This, in fact, would result in being trapped in a terrible 'non' space with no escape. So, the only way one could feasibly experience a world running backwards, would be if time in their 'normal' world was suddenly reversed.
