[Duck Tales] Is it really possible for Dagobert to swim and dive through all the money according to our laws of physics? If not, how could the laws of physics be altered to make this possible?

The reason that Scrooge McDuck lives is able to swim in a pool full of coins is that the force of friction is almost non existent in his universe. Things just slip past each other and hardly interact at all. That means he can jump into a pool and the coins slip out the way like water. 

It's the same reason that he and his family don't wear anything on their lower halves - trousers etc would just slip off them too easily, so they don't bother. 

Any other individuals that you see them interacting with who DO have clothing on their lower halves (e.g. Mickey) have evolved pubic hair that functions a little like Velcro and keeps their clothing up. Ducks however haven't evolved this, as they have feathers, so can't wear trousers.
